Bat script funny. We write with programs (scripts) using Windows Notepad. Scripti is not that simple. We write a detailed virus that opens “endless” windows
If you have recently started programming and have not yet tried to play with the installed operating system, then manipulating additional scripts may result in reasonable nutritional necessity and ease of use. However, to ignore the simple fact that they help better understand how the OS functions, in the future, with the addition of additional Wi-Fi scripts, it may appear very ugly.
To download offensive scripts, we go to PowerShell. Any system administrator (behind the scenes at heart) knows his capabilities and periodically tests himself, for all others it’s just a command line interface or a foreign word. On popular resources you can find a lot of ideas on how to use PowerShell to develop and manage, and then we will look at simple scripts that will help you get up to speed.
Vimknennya and restartWell, the simplest operation is to connect your computer. Open the notepad and write:
shutdown -s -t 0
We save the file as *.cmd (* - the name of your file, for example shutdown.cmd) and do not forget to select “all files” in the type. That's it, download the file from the launcher on your computer. “-s” in this case means embarrassment, replace with “-r” - remove re-invitation. “-t” – timer, we set it to 0 seconds, otherwise set it to 60 – cancel it after 60 seconds.
Seemingly unnecessaryWith various packages installed on a computer or laptop, you can end up with a number of completely unnecessary software packages. It’s easier to delete them using a script:
get-appxpackage -name *APPNAME* | remove-appxpackage
As you understand, *APPNAME* is the name of a non-tsikava. So, you can remove these packages using the standard method or through special programs, or you can create a script that will remove them all with one click.
Careful processesThere are two powerful commands in PowerShell that allow you to deal with windmills (processes that reduce speed code). You can simply display them on the screen:
Or information about a specific service under the code name *NAME* (at which place is the name of the service to click):
Get-Service *NAME*
This can be done in the task manager, and the active file axis can be displayed, which, when clicked, closes all processes with related resources (browsers, antiviruses, etc.). For this, use the Stop-Service command:
Stop-Service -Name *ANTIVIRUS*
Stop-Service -Name *BROWSER*
Name to replace the one entered with * *.
Renaming a group of filesAnother annoying problem: you copied images from your camera or phone. There is a large collection of photographs, which are called similarly by the symbol HGNMD034, where HGNMD is the name of the hidden directory that contains files, for example, taken in one day. In order to make the names of these files acceptable or to be able to combine several folders without losing the chronological confusion through the names, you can use the group renaming script:
$path = "$comp\desktop\journey\russia"
$filter = "*.jpg"
get-childitem -path $path -filter $filter |
rename-item -newname ($_.name -replace "HGNMD", "RUSSIA")
In the first row in the paws, indicate the exact path to the files. The other row has file extensions that facilitate changes. In the rest of the row, replace "HGNMD" - the name in the file names, which encourages replacement, with the replacement "RUSSIA" - the name you want to include. If you save this script again as a new file, then similar operations of the same type will take you every few seconds an hour.
Shukaemo filesAnother simple task that can be implemented in PowerShell is to search for files in a directory. In this case, let's look at the log files:
Get-Childitem C:\Windows\*.log
Or a little folding butt, if the search is carried out, there are also subfolders:
Get-ChildItem C:\Windows\* -Include *.log -Recurse -Force
This is a slightly more correct and new entry, where "Include" - indicates the searched part, "Recurse" - searches for nested directories, "Force" - searches for including system files.
DovidkaNow, we have become more and less familiar with the basic principles of PowerShell functioning. It’s just too stupid to get to the preliminary information like this:
Get-Help Services
This is a command that displays available commands on the screen with a short description. Do you want a report? There is nothing simple:
Get-Help -Name *CMDLET*
Instead of *CMDLET* insert a command to click.
Now let's move on to simple scripts, described with a few simple commands. For example, with the help of PowerShell you can also read all the information about the product and accessories. As an option, here is a script for estimating the level of battery charge:
Add-Type -AssemblyName System.Windows.Forms
.GetConstructor("NonPublic, Instance", $null, @(), $null).Invoke($null)
Architecture of the processor of the remote computer:
Assembly.GetType("System.Management.Automation.PsUtils"
).GetMethod("GetProcessorArchitecture", 40
).Invoke($null, @())
Another important task is checking the administrator's rights with the online account manager. Axis simple PowerShell method:
Assembly.GetType("System.Management.Automation.Utils").GetMethod(
"IsAdministrator", 40). Invoke($null, @())
Why don't you leave it alone? As you have already learned, PowerShell is not a very complicated, but rather a simple tool that can be used to perform the simplest operations, so it is quite complex. However, PowerShell is not a single tool for creating scripts for Windows. Ale about the coming time.
Viruses are dangerous programs that can be passed on to others (or others), and we think that your computer can be hacked, infected with a virus, or seriously damaged. Viruses can be written in a simple Notepad: you just need to write down commands in the file that will enhance the computer’s operation, change the operating system’s operation, or simply write to the user, and then ask him to run this file. Hot viruses can happen at any time, starting with annoying inconvenience and ending with a nightmare that destroys the functioning of the system. "Viruses" in this article are only meant for emergency situations, and the worst that they can generate is to turn on the computer. Please note: these hot viruses are only intended for computers running Windows and cannot be run on Mac OS without special preparation. Let's finish with Crocus 1.
Kroki Writes a subdivided virus that opens “endless” windowsLaunch Notepad. Batch (.BAT) files contain commands for the computer in text view. In order to write a BAT file, you don’t need a special editor—Notepad or a standard set of Windows programs is enough. Notepad can be found in the Start menu or the Accessories submenu. You can also open Notepad by pressing the Win + R key, in the text field of the dialog box that appears, type “notepad” and press Enter.
Dial @echo off, and then, from a new row, CLS. Once the BAT files are finished, open the command row window and display the commands to be completed. The @echo off and CLS commands cause commands to appear in the command row window, eliminating the cause of the heat that is invisible to the “victim”.
Write commands to open a multiplicity (or an uncounted number) in a window. Now is the time to write a sequence of commands, each of which your virus will open on many windows of different programs once or be uninstalled in the same window indefinitely. It is important to know that if the window opens incessantly, your computer may freeze. Read more about how to avoid being offended by the virus:
- To open the number of windows, type the command in Notepad from a new row: start (program names). Replacing the phrase in the arms, enter the name of the program on the “victim’s” computer or else or outside the file that is being saved. This command instructs the computer to open the program window. For example, start iexplore.exe will open an Internet Explorer window. Repeat the "start" command as many times as you want, and your "virus" will appear as many times as you specify. There are a number of programs that can be entered after the “start” command:
- iexplore.exe - Internet Explorer browser
- calc.exe - Calculator
- notepad.exe - Notepad
- winword.exe - Microsoft Word
- To open the blank window, type :A from the new row, including the double box. In the next row, type start iexplore.exe (or another program). I, find it, type goto A next to the bottom. This sequence of commands is to shut down the computer, open the Internet Explorer window (or any other program), turn to the place right before the window opens, and then immediately open a new window, until the window opens the command row will not be closed or the computer will not freeze.
Write to “virus” with a message. For the most greedy effect, you can add information to the “virus” in order to make the owner think what’s wrong with his computer. To display notifications, start a new row and press notification echo. Then from the new row type pause. The "pause" command will cancel the virus after the notification appears.
- To make your fire believable, write a notice similar to the notices about strikes, for example: Fatal strike. C:// directory poshkodzheno.
Save text as a batch file. When you're done, select File > Save as... from the Notepad menu, and then select the file extension “.bat” (for example, “pinball.bat”). In the “File type” list, select “All files”. Save the file here on the “victim’s” computer.
Please click to open the file. To achieve your passion, you need to work in such a way that the “victim” launches it. This can be reached in different ways. One of the most effective is to create a shortcut for your batch file and change its icon to something you can easily navigate to, and then change the name of the shortcut so that it matches the end. Sit back in your chair and watch out for the results of this manual task!
How to write. VBS with information about mercy or evilLaunch Notepad. As in the latest heat, you need to write a bunch of simple commands in Notepad. However, this time the effect will be different - instead of opening this heat, it creates a lot of information about the damages, which makes it difficult for the customer to think that there is a problem in the robot operating system or the computer is damaged.
Type "x=msgbox("Message text", 5+16, "Message title") exactly as indicated here, including the arms and legs, and replace the "Message text" and "Message title" with the desired text. This command opens the standard The window of the Windows repair dialog window is based on the notifications you have assigned about the repair and the title of the window. To make your fire believable, check out the notifications and headings similar to those in the reference. For example, try the title “Terminal repair”, and as reported nya - "U katalozi C:/ /Users /Windows/system32 has detected a critical problem."
- You might want to unleash your heat against the truly evil. At this time, send a message to the vikorist: “I have new access to your system. Get ready for the evil." In reality, nothing like this will happen, and it only applies to people who are bad at understanding computers.
- Viraz “5+16” instructs the computer to open a dialogue window with the critical strike icon and two “Repeat” and “Skash” buttons. By changing the numbers, you can remove different types of results from calculations. Just substitute the numbers below, either a one-digit number for 5 or a two-digit number for 16:
- 0 (OK button)
- 1 (OK and Skasuwati buttons)
- 2 (Skasuvati, Repeat and Skip buttons)
- 3 (Buttons So, Ni, and Skasuvati)
- 4 (Buttons So and No)
- 5 (Repeat and Skasuwati buttons)
- 16 (Critical kill icon)
- 32 (Help icon)
- 48 (Forward icon)
- 64 (Information icon)
Repeat the message about the meal as often as possible. Repeat the commands as many times as you like, being informed about the amends. Messages will appear one by one, so that as soon as the customer closes one message, another will appear. You can highlight this fact in order to create a long-term awareness of the increasingly unsettling character.
Save the document as Visual Basic (VBA). Once you enter all the required information, save the file. From the Notepad menu, select File > Save your..., give the file a name with the extension “.vba”. It’s easy to select “All files” from the “File type” list. Now, to get going, you need to make the “victim” run the entire file, for example, the Vikorist trick in method 1.
Vikorist is writing a batch file in advanceLaunch Notepad. This is the hottest command from Notepad to reset the computer and open the program randomly until the batch file is disabled or the computer freezes. To use this functionality, you simply need to copy and paste the commands assigned to this section. However, please note that this does not work on all computers.
Copy and paste these commands: @echo offclsbegingoto %random%:1start cmd.exegoto begin:2start mspaint.exegoto begin:3start pinball.exegoto begin:4start iexplore.exegoto begin:5start explorer.exegoto begin:6start solitaire.exe explorer.exegoto begin:8start edit.exegoto begin:9start iexplore.exegoto begin:0start mspaint.exegoto begin
Change these commands to the authorities. This code will inevitably open the program entered after the word “start”. You may have noticed that certain programs are repeated. Change the program list as you wish.
- Please note that these program names may not be correct for some machines, for example, “pinball.exe” may not appear on some computers. You should double-check the correctness of the program names before moving the virus-hot onto the “victim” computer.
- If you are unsure about the name of any program, remember that the exact program is the same. For example, instead of "iexplore.exe" you can write "C: Program Files Internet Explorer".
Save the text as a batch file and run it (if you like). Save the file with the extension ".bat" by selecting "All files" from the "File type" drop-down list. If you get the urge to launch it, you can easily open the program on your computer without any hassle.
- To make it more fun, try replacing “*.exe” in one of the commands in the opposite direction to any document of the correspondent. For example, "start C:\Documents\123.doc" opens document 123.doc from the "Documents" folder in the editor for instructions, and
edit (outside the file name)
goto begin
Open the instructions file in a DOS text editor. This is how it looks like the hacker reads specific documents. Remember that I have a file, to take revenge for mistakes, it’s my fault!
As a Linux system administrator, it’s very early on that you come across such concepts as “ script”, be it one of the most exciting scripts on kshtalt /etc/rc.d/rc or writing a configuration script by a software developer configure. In this article I will try to show that scripts are written on shell It's not over-the-top and is entirely suitable for introducing newbies to Linux.
Let’s finish by figuring out what is meant by English terms shellі script. Shell, or the shell, which translates this term into a command interpreter, an interface between the computer and the operating system, and the kernel. Alas, there is still a lot of effort in programming and writing scripts. You can combine your service words and constructs and allow you to write in a new program. This program of my scripts is called script, you can include system calls and operating system commands, as well as external utilities that create powerful tools for system administration.
One of the tasks of system administration is backing up important information. So let’s look at the example of a script that implements back-up information.
Cob of cobsWell, first of all, we need to understand the structure of the script. There's nothing fancy about it. By the way, the simplest script is simply a rewrite of system commands. For example:
Echo This is just an example
whoami
uname -a
These commands are combined in one file. Ale shell is responsible for knowing that it is responsible for processing this file, and not just reading it instead. For whom there is a special design: #!
This design is called “ sha-bang" Yes, # specifies a comment, and in this field sha-bang means that after it we go to the script. For example:
#!/bin/bash
#!/bin/sh
#!/usr/bin/perl
Mi zupinimosya on Bash, Bourne-Again shell. This shell is installed automatically on almost all Linux systems, and /bin/sh is used on new ones. When the script is finished, say the service word exit.
Having become familiar with this knowledge, let’s write our first script:
#!/bin/bash
echo Simple script # The echo command displays notifications on the screen
echo V:
whoami #whoami shows the name of the registered customer
echo Your system has started
uptime # uptime shows the hour the machine is turned off
echo Today
date # date shows the exact date and hour
echo Bye bye
exit
Save this file under the name tutor1.sh. Enter the command to create the script.
Chmod +rx tutor1.sh
The result of viking the script will be:
:~/Doc/Open Source$ ./tutor1.sh
Simple script
In and:
voland
Your system has started
14:38:46 1:48, 2 koristuvachs, load average: 0.47, 0.43, 0.41
Today
Sun Lute 26 14:38:46 MSK 2006
Leave it all
Now that we have learned to write simple scripts, it’s time to move on to serious speeches: writing a script for backup.
First of all, we need to figure out a backup copy of what we have. Therefore, our script can work with the command row. Command line arguments are specified after the script name through a gap: somescript arg1 arg2 arg3. The script accepts arguments by numbers of their direct line, so we use a construct like $argument_number, then. $1, $2, $3. $ is a wildcard symbol that we will need during our work. Changes in the script are specified as change_name=values. We will use the following changes: MAXPARAMS to determine the maximum number of command line parameters, BACKUPFILE to specify the name of the archive, BACKUPDIR for the folder, a backup copy of what we are working on, and ARCHIVEDIR for the folder where the archives will be placed. . The main part of the script will be the commands to search for and archive all found files and folders with values:
Find. -type f-print0 | xargs -0 tar rvf "$archive.tar" > /dev/null
gzip $archive.tar
Let's figure out what the commands are. find searches in the stream directory (the first argument ".") for all files and shows the next path to them (print0). These paths are redirected to the tar command, which collects all files into one. Then, using the gzip command, we archive the tar file that you need. Team > /dev/null manual if you archive a large number of files. In this case, their names and directions to them are not displayed on the console.
The next step is obliged to pass on the instructions of the koristuvacheva, as if he were using the script, in order to avoid allowing any kind of compromise.
For example, this design
If [$#-lt "$MAXPARAMS"];
then
echo
echo
exit 0
fi
It will be shown that the koristuvach showed the insufficient number of arguments in the command line. If [umova]...fi sets the mental structure. $# -lt "$MAXPARAMS" checks the entered number of parameters and if this number appears smaller than MAXPARAMS, then you will see a notification about the correction entry. Exit 0 Exit the script and assign it to the robot without inserting the execution code. In the same way, the permutation of the permissible number of parameters is checked, only instead of ls (less then – less, lower), it is necessary to specify gt (greater then – greater, lower). Now, if the main points of the script are clarified, you can move on to the next version:
#!/bin/bash
# Description:
#+ Create a backup copy of all files in the designated directory
#+ for "tarball" (tar.gz archive).
#+ Vikoristannya:
#+ sh backup.sh archive_name folder-dzherelo folder-appointment
#+
# Maximum number of command row parameters
MAXPARAMS=3
if [$#-lt "$MAXPARAMS"];
then
echo
echo "Vikoristannya: sh `basename $0` im_archive-folder-dzherelo-folder-attribution"
echo
exit 0
fi
if [$#-gt "$MAXPARAMS"];
then
echo
echo "This script needs more than $MAXPARAMS command line arguments!"
echo
exit 0
fi
# Changes like we vikoristovu in the script
BACKUPFILE=$1-backup-$(date +%m-%d-%Y)
archive=$BACKUPFILE
BACKUPDIR=$2
ARCHIVEDIR=$3
# We verify that this is a folder-djerelo and a folder-acknowledgment
if [! -e $BACKUPDIR];
then
echo
echo "\"$BACKUPDIR\" doesn't matter!"
echo
exit 0
fi
if [! -e $ARCHIVEDIR];
then
echo
echo "\"$ARCHIVEDIR\" does not exist, we are creating..."
mkdir $ARCHIVEDIR
echo "Done."
fi
# We check what archives Dzherelya has and acknowledge.
cd $ARCHIVEDIR
if [-e $archive.tar.gz];
then rm $archive.tar.gz
fi
cd $BACKUPDIR
if [-e $archive.tar.gz];
then rm $archive.tar.gz
fi
# The main part of the script...
echo "Robimo backup copy \"$BACKUPDIR\" file \"$archive.tar.gz\"..."
find. -type f-print0 | xargs -0 tar rvf "$archive.tar" > /dev/null
gzip $archive.tar
echo "\"$BACKUPDIR\" was successfully archived from the file \"$archive.tar.gz\"."
# Moving archives to the ARCHIVEDIR folder
echo "Moving archives \"$archive.tar.gz\" to the folder \"$ARCHIVEDIR\"."
mv $archive.tar.gz $ARCHIVEDIR/$archive.tar.gz
echo "Done."
I hope that I have commented on the main points in my report. If you have any problems with food, then you can contact me for the address. I also recommend the wonderful book by Mendel Cooper, which has really helped me in my time, since I only became familiar with the scripts. Successful programming.
P.S. Thank you very much mar for your respect and respect.
With this article, you won’t learn how to program and you won’t even be able to write such a program, but you will find here the wonderful VBS scripts and BAT files that you can easily write in a basic Windows notepad, you can perfect it on your own, then brag to your friends and close. Perhaps, if you lift your spirits, you will have a wonderful time.
Most similar scripts are written for ease of use and automation of any actions on a computer running Windows OS. The scripts presented below may not seem too colorful (maybe I think so), but they are definitely suitable for a basic understanding of “coding”. You will have a wonderful time enjoying yourself and the teapots you know (not programmers), plus one more delicious option.
A little bit of terminology:
- VBS is a language program for creating scripts in Windows, created/edited in Windows Notepad, may be called ".vbs". I think there’s no sense in continuing to chew, because there’s not much to say, especially for beginners. Who's going to make a fuss - .
- BAT is a batch file, popularly known as a batch file. Extension of the ".bat" file. Further similar -.
These files (vbs, bat) can be created in any popular Windows Notepad (Notepad). For greater ease of creating scripts, it is recommended to use the advanced (let's say) notepad - Notepad++. If you are familiar with the syntax of a large number of our programming, if you don’t have enough to talk about, then download and write from someone - you will create fewer errors in the code, or it will be easier to know them, without the same low-functionality Block Windows notes.
For accuracy, butt (left-handed – Windows Notepad, right-handed – Notepad++):
Let's get startedIf you are already familiar with VBS scripts and batch files, then for all the lower-level applications you will not have any problems, as if you are a beginner, then for basic knowledge - those that are needed.
Let's start using the computer
Set sapi=CreateObject("sapi.spvoice")
sapi.Speak "Hello!"
One aspect: if you have written the words in Russian letters in the tabs, and when you start it is obvious that you simply do not have the Russian voice engine installed. The detailed installation and customization of the voice engine is beyond the scope of our article, so read more about it and come back here again.
Now, let’s do this: we’ll write this script in AutoZan, which means that when you start the computer, you will be prompted to write a word (words) in the program, just like in an application, then you’ll say “Hello” when you turn on the computer. How can you earn money?
It’s simple, you can add a program (script) to AutoZan in the same way, through the same VBS script. Create a file in notepad, copy/paste (Ctrl+C/Ctrl+V) following code:
Dim vOrg, objArgs, root, key, WshShell
root = "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run\"
KeyHP = "Program"
Set WshShell = WScript.CreateObject("WScript.Shell")
WshShell.RegWrite root+keyHP,"C:\Privet.vbs /autorun"
We change the path to the “talker” script, the axis of this row is C: Privet.vbs to yours. We'll tell you where you have this script and what it's called. Next, we carefully create the program in Notepad and launch it. That's it, now the computer will be with you when your skin is turned on.
Unlock the drive
Set a = CreateObject("WMPlayer.OCX.7")
Set b = a.CdromCollection
Set c = b.Item(0)
Set d = c.
Here is the correct modification of this script:
Set WMPlayer = CreateObject("WMPlayer.OCX.7")
do
WMPlayer.CdRomCollection.Item(0).Eject()
loop
In this case, the CD/DVD drive opens and closes for an entire hour; on laptops, this device opens and closes after the skin closes.
Respect! Another code (opening and closing the drive) can be treated as a bad program by antivirus software. Kaspersky Antivirus (including) you can download it yourself this way and immediately. The first option (just open the drive) for anti-virus programs does not have a bad script.
To enable automatic opening and closing of the drive, you must:
Gra
Tsikava nakhidka z Merezhi – game on VBS. You need to guess the number from 0 to 100. When you start the script, the script automatically sets (guesses) the number you need to guess and enter in a special window; if the answer is incorrect, hints are given, for example, less or more.
Below is the same code that you need to copy and paste into Notepad and save (extension.vbs).
You can also change the message to your own taste; everything written in Cyrillic can be edited without any problems. Don't be afraid to hack the code. Experiment. If so, please copy the working code again.
Set y = CreateObject("Scripting.FileSystemObject")
Set y = Nothing
Do
a = 0
u = 0
Randomize
Number = Int((RND*99)+1)
MsgBox "I guessed a number from 1 to 100, try to guess", 64, "Guessing"
Do
a = a + 1
c = InputBox("Guess the number" & vbCrLf & vbCrLf & "Try: " & a & vbCrLf & vbCrLf & "To see the results, enter the number!" & vbCrLf & vbCrLf & "To exit, leave the field empty" & vbCrL Guessing)
If c = "!" Then CreateObject("WScript.Shell").Run "Notepad C:\Windows\Result.dll",3
If c "" Then
If IsNumeric(c) = True Then
If CInt(c) If CInt(c) > Number Then MsgBox "Ni, not " & c & ". I guessed a number less than",64,"Guess"
If CInt(c) = Number Then
Set y = CreateObject("Scripting.FileSystemObject")
MsgBox ("Number of tests:" & a)
If MsgBox ("Correct, this is the number " & c & ". Start over again?",36,"Guess") = 6 Then Exit Do Else WScript.Quit
End If
Else
MsgBox "This is not a number!",16, "Guessing Game"
a = a - 1
End If
Else
a = a - 1
l = MsgBox ("You don't know anything. Log out with programs?",36, "Guessing Game")
If l = 6 Then WScript.Quit
End If
Loop
loop
Well, before that, let’s move on to the batch file (.BAT) quickly using the best VBS script from all the lists in this article.
The script that wscript.exe closes
The script itself:
Set TaskKill = CreateObject("WScript.Shell")
TaskKill.Run "TaskKill /f /im wscript.exe"
In essence, you have to do the same thing that was explained a little more in the task manager, as for example, you can’t just open and close the disk drive that opens and closes the script, and all launches that run this script will be closed. It's like beating a wedge with a wedge.
We've learned a little about VBS scripts and how to write them in notepad, now we'll look at a number of applications for writing BAT files (hereinafter referred to as a batch file).
A very simple batch file that can be completed in just one row.
shutdown -s -t 1 -c -f
This is the code version:
shutdown -r -t 1 -c -f
Also, write in notepad, save with extensions.bat and after starting the computer, restart (restart the computer).
Vidalennya update
This body shirt will be in good hands in that situation, as you already are. What's the point? This batch file has overhauled commands with many updates, as can be seen from the name - telemetry update, or just one of the tricky little things of the system, and once they told you how to turn it on, in this case you simply create a batch file, instead of copying it follow the code below and run it, After which the list of updates will be seen.
@echo
echo
echo Step 1: Delete Updates Telemetry
wusa /uninstall /kb:3068708 /quiet /norestart
wusa /uninstall /kb:3022345 /quiet /norestart
wusa /uninstall /kb:3075249 /quiet /norestart
wusa /uninstall /kb:3080149 /quiet /norestart
In this way, you can see absolutely whether it’s updated, update KB971033, or verify it.
There are a lot of different scripts on the Internet, none of them harmless, but be careful, first try any script, they can be harmful, for example, make changes to the registry, and for some reasons the system is available for payment, in this case it will happen either Windows or develop an updated system.
Vitannya. It's been a while since we've had a lot of fun with jQuery. Today we are working on a scrolling script using jQuery. This is necessary practically on every site, and you don’t even want to create a third-party plugin for a third-party plugin with a mountain of unnecessary code.
Since the theme itself created for the site is not worth it for you, then the creation of the site on a turnkey basis by professionals is an excellent decision.
How to create a script for scrolling uphill using jQueryLet's get it simple, HTML:
This is the code of the button itself, which needs to be added to the HTML.
Let's move on to the CSS, describe the style of the button, make it statically right-handed at the bottom, in front of the view, in shadow, round and so that when hovered it becomes noticeable.
To avoid adding the arrow symbol to the HTML and to simplify the layout ourselves, we added it via CSS. In addition, we have described everything for the button in CSS - it is round and dark, fixed at the bottom right, and when hovered over it becomes visible.
We're done with CSS. Now let's look at jQuery. In jQuery we have 2 speeches:
- It is important to show the button “up” or no (below the scrolling stage of the page)
- Smooth scrolling of the page up when you press the button
So let’s do it:
Initially, we note that the page is scrolled, and we need to make a new adjustment: if the page is scrolled more, the screen size is lower, then you can still show the “up” button, if the page is scrolled less, then the same when wow.
Then we add a sample of the click on the “top” button. We have the same power as scrollTop in html and body (for cross-browser compatibility).
Done, the button works.
You can view the result here:
The button is not visible right away, you need to scroll the preview area a little (to check the manual and check).
You can safely install this code on the site, and you will be glad that it works and does not require additional plugins and scripts. There are only a few rows of code in JS, CSS and at least one row in HTML (you can also do without HTML, and only use JS to add a button to the new one after loading the page).
How to write scripts for an operating system, websites or just igor? The information on this, a simple diet, and will be considered within the framework of this article.
Secret informationIt’s really important that you want minimal knowledge about programming. If you find yourself foolish, then this article will help you fill up the clearing. Let's first understand what a script is. This is the name of the algorithm that writes song programming that is stored on a person’s computer and can interact with song files, programs on the browser’s desktop, and system settings. This allows you to significantly expand the standard capabilities, create automated assistants, and take on part of the work.
Let's start using browsers
This might be one of the best places to take. If we write scripts in JavaScript, then a basic notepad is enough to know this programming. True, there are some shortcomings here. So, a skinned person who uses the same “Notepad”, you might wonder what a script is. And if someone has bad intentions, and the code is leaking, then problems may arise. In addition to learning how to write scripts in JavaScript, it is important to know that it is enough to learn this programming. In order to create beautiful and complex programs, you can quickly access different libraries. Otherwise, they require specific web browser extensions. And when changing computer equipment, it will be necessary to carry out additional adjustments. And when using third-party developments, it is necessary to re-convert so that the script cannot be overpowered by the user on third-party services. Please note that your browser may contain songs. With this help, you can do practically everything you can. What is the best thing to write about in such situations? This is necessary if you want to automate human activities.
Works with the Windows operating system
Let's say we need to change the computer configuration. And this is due to the widest range of graphical features, but, unfortunately, we don’t like it. He often has to create system scripts. The stench looms large. Every person, who spends most of their time working at a computer, is already familiar with such files. How to write a script for Windows? For this we need the same “Notepad”. I'll create a new text file first. You need to write down system commands. After this, you need to change the file extension to .bat. I will be deprived of starting this development. If everything is correct, then the commands will be in the distance, and you can learn more. Otherwise, nothing will happen to the code if it is not written down. It’s better to understand what you write down. Just take the code here and mindlessly insert it, it is categorically not recommended! This can lead to significant problems with the robot's operating system. And also forgive me, since such unsafe actions were taken out of the guest account. Even a command from the administrator can turn the computer into a “fixed” state.
What about Linux?
Please remember that Windows is one operating system. And also “Linux”, and it’s still popular. How to write scripts for this operating system? They are created behind an additional shell - a special command interpreter, which is the interface between the human and the kernel of the operating system. In Linux, scripts, in essence, are just a file that uses system commands. It’s simple and instantly easy. You also need to know how to process such a file. He just reads after the promos. And if it is necessary to sign, the construction “#!” is used, which must be placed in front of the command. All scripts may be expanded. It should be noted that with help you can easily complete a lot of well-formed speeches. For example, backing up files. The range of options for vikoristan is extremely rich.
I'm looking forward to writing a script
So, first of all it is necessary to figure out from the middle where we are typing the code. For the most part, one “Notebook” is enough. However, it is no longer easy to represent a real structure, since operators and other elements are not highlighted. Therefore, as a good alternative, you can use the Notepad++ program. For those who know the English language, it is not so easy to translate it as a Notepad. Ale iz expanded capabilities. This is small, but even the most accepted technology is primarily oriented towards programmers. You can turn on the adjustment of the display for everything that it is. A handy tool for displaying code and avoiding other things you might want or need, to make the writing process more comfortable. In general, nutrition “to write scripts” is given without any variety of evidence, in which the skin demonstrates its peculiarity. And even more sophisticated middleware, with emulators and without any tools for improvement. Choose what amuses your soul. After all, it is necessary to speak about the clarity of knowledge. As a basis, we will follow up with your programming and operating system commands. To learn more, you can read a number of books that explain the specifics of machine logic and code processing.
Services start in real timeHow to learn how to write scripts, do not skip the steps and the possibility of getting started with the help of additional information and lighting technologies. What does this “forge of programmers” look like? Following the program, based on the thoughts of the experienced specialists, the newcomer is led from the easiest to the most difficult moments. So, from now on you can dynamically update the data in order to move on to the creation of socket servers. And people go through learning without haste, step by step, acquiring the maximum amount of data. If something goes wrong, you can rush to help them. It’s not a fact that the first one will satisfy all your needs, but it will be necessary to simply try something else.
What's the point of getting married?
It’s a lot of fun to write scripts for igors. Well, it’s not very difficult, but there’s not a single stagnation of such possibility. Well, let's take a look at the butt of the gri. It is acceptable that people should play on a singing site for fun. Ale, unfortunately, conveys that it is necessary either to invest your pennies or to finish singing for a long time and monotonously. And if another route was taken, then the scripts are the same as what is needed here. The same can happen in stationary games on a computer. There are characters under the control of a piece of intelligence, and in order to fight against it, you can create your own version of II, thus controlling the battle of the computer with itself (and for easy passage). But scripts can be successful in games, not just in games. It is possible that this is the website of a serious company. An important aspect is the maximum support for communication with clients. And for this purpose, the script is given a small form, in addition to which you can get online consultation with a specialist. There are a lot of possibilities!

It’s a pity, but within the framework of the article it is very important to convey how to write scripts correctly. You can, of course, vikorist gibberish phrases about those that the code is supposed to take up less space, be optimal and much else, but it will only be possible to understand in practice. Even more evidence and searches for optimal solutions can help in the implementation of programs in such a way that they complete their commitments with minimal effort. The programmed ones, and not just the written scripts, have a lot to learn from practice! Therefore, it is necessary to carefully study, become more precise and think about how to implement the assigned tasks as quickly as possible.
Instructions
Depending on the type of script being executed, the scripts are divided into “client” and “server” ones. By going to any address in the middle, we send the URL of the page to send to the server, and it launches the script located behind the specified address. The script, which ends on the server, is programmed with a new activity, selects the page from the necessary blocks and sends them to the browser. Tse is a server script. Having extracted the page, the browser on ours renders it for us, and if there is a script in the extracted code of the page, then it is now engaged in the execution of that script. This is a client script.
So that the server or browser can read, understand and view the script, it can be stored and recorded according to the rules it knows. Such sets of rules are called scripted programming languages. Most server-side scripts these days are written in my PHP, and most client-side scripts are written in my JavaScript. To write a script, your primary text editor is notepad. To program scripts smoothly, you cannot do without a specialized editor. Such an editor takes on the left side of the routine work from writing scripts, depriving programmers of more than an hour for creativity.
Let's write a simple server-side PHP script. First of all, you need to tell the Viconavian where the scenario begins. In the PHP language, the tag that opens looks like this: Between these two tags there are instructions - language. For example, to overwrite the writings written by O. Bender on the Caucasian rocks, like this: echo ("Here are Kisya and Osya"); And the instructions for displaying the exact hour in the HOUR: KHVILINA format are written like this: a PHP script, combining these operators, will look like this: echo date ("H: i");
echo ("here are Kisya and Osya!");?>After writing this script, the Vikonavian program (movie interpreter) looked like this:
And this script in client JavaScript will look like this: var now = new date();
document.write("In");
document.write(now.getHours() + ":" + now.getMinutes());
document.write ("here are Kisya and Osya!"); Here the line var now = new date() gives the script the command new object with the name "now", which is the current date and hour. document.write() – this is to write on the side what is indicated on the handles, and the commands now.getHours() and now.getMinutes() punish drawing from the “now” object exactly the same time.
For greater accuracy, it was better to combine two scripts into one file, save it on the server and type the URL in the address bar of the browser. As a result, there are essentially two rows, one of which follows our script on the server (PHP interpreter), and the other - on our computer (JavaScript interpreter).

- Scripts for the website html - where they are and how to install them
Internet software will always have to obtain some kind of virtual computer before installing the necessary programs on the browser or server. Actions may include, for example, visual effects or processing of data entered into the browser. Or a folded-up page from adjacent blocks on the server. The virtual controller for these actions will be the server or browser software, and the script for the controller will have to be written using one of the script programs. To get rid of the false statements about how scripts fail, let’s write a simple script in JavaScript.
Instructions
The JavaScript script is completed directly, so everything you need to write the script is already with you. As a working tool for the programmer, we will use the primary text editor - the standard Notepad. This is entirely enough to create a simple script, or, obviously, for a more efficient and specialized editor. First step: create a new document to write instructions to the browser.
Now you can print the code with instructions. The browser understands more than one language - for example, to lay out the page, the HTML language (HyperText Markup Language) is used, and for an extended description of the appearance of the page elements - the CSS language (Cascading Style Sheets - “cascading tables”) styles"). To make this scenario clear that part of the page's output code is written in JavaScript, all instructions require placing in the middle of a tag that opens and closes: Instructions by JavaScript operators. For example, read and remember for later in the script the exact date and hour looks like this: var aTime = new Date(); Another instruction is to write any information in the body of the page - it looks like this: document.write("any information"); Restore respect - here is an indication of the object named "document", which does not need to be created, but will be automatically. This is a virtual image of the flow side. From this object you can extract information about the page and from it you can perform various transformations - for example, in this row of code and with the help of the write operator, the text “as well as information” was written into the document. :document.write ("Working hour" + aTime.getHours() + ":" + aTime.getMinutes()); Here, with a simple addition operation (+), we have collected several storage parts of the row. The rest of your simple script looks like this:
Writing or editing a colorful web script is half the job, you still need to know how to log it out. Let's take a look at what is needed to create the most advanced types of scripts.

Obov'yazkova's mental witchcraft of any script (or script), naturally, is the obviousness of the wickedman himself. One hundred mov-programming by such a Vikonavian will be a scripted movie interpreter. Moreover, depending on the script, the movie interpreter can be part of the server software, or part of the browser code. Therefore, in order to view any server script (for example, PHP or Perl script) it is necessary to start the server. The server can be selected in a network or in itself. Very popular, for example, among Russian programs due to its remarkable simplicity and cost-free server software under the name “Denver”. Instead of bothering with your own installations, you can quickly use the services of a hosting provider. The provider will give you access, and all turbos will not interfere with your support and service. Call such fees, rather than expensive ones.
Follow “client” scripts. These scenarios that may end up directly in... To write such a script, for example, using my JavaScript in a browser and a simple text editor (use a standard notepad), nothing else is needed. The axis, for example, is the simplest script: var now = new Date();
document.write("This script is in " + now.getHours() + " year old " + now.getMinutes() + " hwilin"); To do this, it is enough to save this code in a file with extended html (for example, test. html) and then run the following mouse clicks. The extension html (HyperText Markup Language) in the operating system is reserved for files that serve as web pages. Then the OS launches your browser and passes it to the address of your file, and the browser recognizes the script, reads and executes your script. As a result, we will use something as simple as the script that goes into it:

You wrote a shell script, but you don’t know how to launch it. Many Linux users are facing this problem. In order for the script to start, it must be prepared in a special way. You can earn money in different ways.
Instructions
The easiest way is to create scripts and run them using the additional Midnight Commander program. Most Linux distributions already have this. However, every day in ALT Linux and Ubuntu, in which case you need to install it by entering the following command: In ALT Linux, to install this program, you will have to download it from the RPM file, and then install it. Go to the folder in which the file is being expanded, using the cd command, followed by the next path to this folder. Then enter the following command: rpm -i ./name file.rpm
Where is the file named.rpm - the file you have installed. In Ubuntu, the process of installing automation is required, for its launch you will have to do everything quickly: sudo apt-get install mc All listed commands are in root mode. Ubuntu does not have such a mode; the sudo command is used before apt-get. After Midnight Commander is installed, you can launch it if you want, by quickly using the following command: mc
Since Midnight Commander is not disabled, you can change the access rights to the file with a shell script so that it can be uninstalled using the following command: file name chmod 755
where filename - the name of your file with the script. Now try running this: ./filename
If you give preference to the Midnight Commander wiki, change the access rights to the script as soon as possible. Launch this program, go to the folder with the file you created, select the next option, then find the “Access Rights” item in the “File” menu. Check the boxes for “Run/search for a leader”, “Run/search for a group” and “Run/search for others” (you may not check these if you do not want to allow other members to run the script). Save the settings using the “Install” button. Now the file in the list will turn green, and a star will appear in front of it. By moving to a new item and pressing the "Enter" key, you can run the file.
In order to properly execute any script, it is necessary to activate it. There are many ways to earn money. Since the problem is most often due to the number of scripts that are used when working with hypertext pages, it’s important to look first at the ways of activating scripts with the most popular languages in this area - JavaScript, PHP, Perl.
Instructions
Since the writing script is a “client” one, its execution, as a rule, does not require the installation and launch of special software. For example, the files of the JavaScript script are downloaded and saved on the user’s computer side by side, as they were created. To click (activate) such a script, find its file and double-click. However, it is important to remember that the script is programmed to expand to the elements of the page, as a result of repetitions. If you activate such a script directly from the side of the page, you can avoid any signs of its work - rather than work by entering the “right” side of the script into the browser.
If you activate the client script after visiting the page in the user's browser, this click can be linked to any point - pressing the button inserted into the page, hovering the cursor over some element, at the end of the hour launched when important timer and other For this purpose, check out all the different attributes. Place the message to the script in the onClick attribute so that it will not be activated when the target is pressed. Vickory the onFocus attribute, since it is necessary to activate the JavaScript script when the user begins to fill out any field in the text input element. The onKeyDown and onKeyUp subsections will help program activation of the script when a key is pressed or released, onMouseOver - when the mouse pointer is hovered, onMouseOut - when the cursor is displayed, etc.
If you need to activate a server-side script (for example, using php or perl languages), do so by typing your URL in the address bar. You can program such a transition in the output code of the page in the original way (as instructed), or by linking it, as in the previous step, to any stage. It is not possible to launch a server script, as you can simply download it and click two times - such scripts are processed using special software. Therefore, to activate it on your personal computer, you need to install and run a suitable set of programs - for example, from which you can access the Denver kit (http://denwer.ru).

Paste the code for sending to the merge window into the body of the page, and describe the script for opening the merge window itself. Describe the click window function using the standard commands show(), TransferTo(), bind() and others. Make sure to write a short description for yourself so as not to get lost in the code, which could completely disrupt the operation of the entire system.
Turn the code over and open the page in your browser to improve the results of your work. To make a leaking window appear, you need to press the seal on the opening. Next, you can change the automatic appearance of the drain window. The drain window also has a variety of characteristics, such as the ability to tug, squeeze, stretch and, of course, close. All these parameters must be described in the merge window script. It doesn't matter what floats, it's important to know the basics of programming, because you need special knowledge to write the code correctly.
JavaScript is a special prototype-oriented language programming. This can be included in the HTML code of web pages, thereby increasing the functionality of the site. The script allows developers of different browsers to make pages interactive, which is why the manual and functional language is becoming more and more popular every day.
Java script is considered one of the most common types of programming, with many similarities to Java, which means the first part of its name. The architecture of this software is low in features, which is primarily due to its similarity with other languages, and in the other – due to its stagnation in practice. One cannot help but notice the power of memory, which can be processed automatically, as well as the dynamic typification of its type, the prototypicality of programming and the visibility of functions that are seen as first-class objects.
What JavaScript allowsA Java script allows you to create beautiful interactive pages that would be impossible to create in pure HTML. As a rule, these scripts respond to any actions of the user: clicking, hovering the cursor, etc. The online price of this video starts when the web page is accessed. You can write a Java script using any text editor. You can look at what is written in your browser and download the script. We are talking about Netscape Navigator (starting with the 2nd version) and Microsoft Internet Explorer (starting with the 3rd version).
Since then, as these browsers have become widely used, almost all business owners have begun to work with my programming, improving the current appearance of web pages and their functionality. Before speaking, scripts may appear differently in browsers. Most of the Java scripts that can be downloaded in Opera cannot be supported.
How to place the finished code in a protected fileYou need to create a sidebar in some text editor and save it. Next, download the prepared Java script code and place it in this page. Save with the same dad, where i.html. Now you need to secure JavaScript connections. For this purpose, you need to create a confirmation entry in the HTML file.
Scripts written by my script? can be displayed on html pages between tags of the same name. Tegu
A notepad for a website is a simple add-on in PHP and JQuery that allows freelancers to write notes. All records will be saved in text files on the server.
Krok 1. HTML
Let's take a look at the layout first. For this purpose, the most important HTML5 document is created, the most important part is presented below, the code can be seen in the output file index.php.
Notatka
As you noted, the layout is complicated, firstly, we add CSS styles, include jQuery and our script script.js. Please note that the phpecho expression is in the text area.
Krok 2. CSS
To form a background for the appearance of a sheet of paper for notes, a pseudo-element is added: after. When you change the size of the text input area in jQuery code, the bottom part is automatically pushed down.
#pad( position:relative; width: 374px; margin: 180px auto 40px; ) #note( font: normal 15px "Courgette", cursive; line-height: 17px; color:#444; background: url("../ img/mid.png") repeat-y; display: block; border: none; width: 329px; min-height: 170px; overflow: hidden; resize: none; outline: 0px; padding: 0 10px 0 35px; pad h2 ( background: url("../img/header.png") no-repeat; overflow: hidden; text-indent: -9999px; height: 69px; position: relative; ) #pad:after( position:absolute ; content :""; background:url("../img/footer.png") no-repeat; width:100%; height:40px; )
Krok 3.PHP
The PHP code for our butt is easy to complete. The note is read and displayed when the page is visited, and if jQuery powers the AJAX request, it is written to the file. The file will be overwritten.
$note_name = "note.txt"; $uniqueNotePerIP = true; if($uniqueNotePerIP)( // Vikorist's IP address for naming the note file. // This technique is useful in situations where the program // Vikorist can create a number of koristuvachs at the same time. if(isset($_SERVER["HTTP_X_FORWARDED_FOR"]))( $note_name = "notes/".$_SERVER["HTTP_X_FORWARDED_FOR"].".txt"; ) else( $note_name = "notes/".$_SERVER["REMOTE_ADDR"].".txt"; ) ) if(isset($ _SERVER["HTTP_X_REQUESTED_WITH"]))( // Pull AJAX if(isset($_POST["note"])))( // Write the file to disk file_put_contents($note_name, $_POST["note"]); echo " ( "saved":1)"; ) exit; ) $note_content = ""; if(file_exists($note_name))( $note_content = htmlspecialchars(file_get_contents($note_name)));
The next step is to increase your respect to the value of $uniqueNotePerIP. If this is set to true, it will create a unique note file with names based on the IP address. If set to false, everyone will select the same file.
Krok 4. jQuery
The work of jQuery in this add-on involves observing changes in the text input area and powering the AJAX post for index.php, where the text will be written to the file.
$(function())( var note = $("#note"); var saveTimer, lineHeight = parseInt(note.css("line-height")), minHeight = parseInt(note.css("min-height") ) ), lastHeight = minHeight, newHeight = 0, newLines = 0, var countLinesRegex = new RegExp("n","g"); ("input",function(e)( // Clearing the timer // saving skin pressure key clearTimeout(saveTimer); saveTimer = setTimeout(ajaxSaveNote, 2000); // Show how many new rows there are newLines = note.val().match (countLinesRegex); if(!newLines)( newLines = ; ) // Increase the height of the note ( as needed) newHeight = Math.max((newLines.length + 1)*lineHeight, minHeight); // Increase/change the height only once when changing if(newHeight != lastHeight)( note.height(newHeight); lastHeight = newHeight; ) )).trigger("input"); // This row will change the size of the note when the page is clicked function ajaxSaveNote())( / Launches an AJAX POST to save the note $.post("index.php", ("note ": note.val())); )));
The primary approach in such cases is to tie the device to the keypress. However, this method is not enough, because users can simply copy the text from the input area, or select a proposition from the browser’s automatic corrector, or use the select/repeat operation.
That's all. Ready!
The current Internet is inexorable without scripts. I'm excited to write in JavaScript.
When they wrote the Bible for the Internet, it would begin like this:
From now on there will be mail. And the engineers said it was good. And they created a stink of WWW from hyperactivity. And the engineers said that it was also good. And we created a lot of JavaScript to create pages.
This is approximately what happened in reality. JavaScript came up with something to “revive” HTML. Scripti JavaScript written without middle to the text HTML or saved in separate files, such as styles CSS. They will be displayed immediately after visiting the page in the browser.
The language itself was originally called LiveScript. Then it was renamed to JavaScript, so they were planning to get involved with Java’s secret significance. But at the same time they have virtually nothing to sleep on, and JavaScript- absolutely independent language programming due to its clear ECMAScript specification.
Formally, JavaScript is a trademark of Oracle, but it is an “extension” of ECMAScript, along with JScript from Microsoft and ActionScript, but rather there are problems with trademark rights. Golovnya, that the free ECMAScript does not belong to anyone.
Zgodom sphere inflow JavaScript has expanded significantly. Yogo started vikorystuvat not only for scripts on the site HTML, and also for serious web add-ons and entire programs that run in the browser. Є tools to specially “package” these programs and uninstall them outside the browser. These compilers and interpreters, as they are more clearly discussed in the introductory courses "" and "".
JavaScript programs end up with some kind of middle ground, which is an interpreter.
We are still limited to browsers and HTML pages.
Yak zrobiti JavaScript? Writing a basic script is as easy as it gets HTML-Storinku, even scripts JavaScript are written in original text, so they can be created literally in the same Notepad, then saved in separate files or pasted into the body HTML document. The simplest speeches in JavaScript It’s really easy to be shy.
How to Write JavaScriptFor example, here is a very simple script for logging into the Windows script server. This script can be written directly in Notepad and Vikonati without a browser.
WScript. echo(" Hello Skillbox!")
Let's write this text "Notepad" Then we save the file under the names skillbox.js and launches in "To the Explorer" Windows.
A similar script can be written directly from the page code HTML between tags і . There you can already vikorize the original JavaScript methods, not the method echo specific object WScript. Let's look at the standard methods for entering and displaying data in the browser.
alert()Method alert() Displays at the end with the "OK" button. The window displays a notification as indicated on the arms. For example, "Hello, Skillbox!". In this case, the browser will work exactly the same way that the script server worked before it Windows.
These applications can also be written in Notepad, but can only be saved in files with extended extensions HTML. For example, skillbox.htm.
alert(" Hello Skillbox")
Result:
Yak argument alert() can be specified as a specific text, and the result can be calculated and processed from other data. For example, alert(x) where x is calculated separately.
confirm()Method confirm() Display the same window with notifications, and also with two buttons - “OK” and “Save”. It is important that the button is pressed, the method rotates or the values true, or false. The server picks up the value that is rotated by the user and selects each action, according to the output.
The syntax is the same, only here it is logical to transfer the choice and then set the power supply.
confirm(" Hello Skillbox")
Result:
Method prompt() display a dialog box with notifications and a text field where you can enter data. Here there are also two buttons “OK” and “Skashuvannya”. After pressing the first button, the method rotates the text to the input server, and after pressing another button, it rotates the logical values false.
The syntax here is:
prompt( information, value_of_data_entry_field)
The input field values are not binding. There you can enter the text, which is the beginning of the introductions in the field of competence of the correspondent.
prompt(" Say hi to Skillbox", "Hello")
Result:
The Possibility of the Daily JavaScript go far beyond the boundaries of the primitive introduction and presentation of data through forms. These methods were given only as the simplest examples. Crimea, JavaScript allows you to respond to the actions of the koristuvach. For example, touching the bear or pressing the singing keys. JavaScript often used for securing asynchronous work ( Technology AJAX), if the information on the page is updated without re-uploading. In this mode, data is uploaded to the server and must be displayed in interactive mode. In addition, JavaScript building manipulation HTML-elements on the page (create and hide tags, etc.) and do a lot more.
Core tools Retailer consoleAll popular browsers have a special browser console. It shows the script code on the page, as well as other relevant information. U Chrome, Firefoxі I.E. The retailer console opens after pressing the hot key F12, V Safari - Ctrl+Shift+I or else Ctrl+Alt+C. In the screenshot of the script, the right hand is displayed next to other elements of the web page.
Chrome retailer console.
Code editorsFor manual programming, you will need to install a code editor or IDE (Integrated Development Environment), integrated center of development. IDE- This editor with extended functionality, which integrates with other core tools, also supports the connection of additional modules.
