Summary of javascript operation file implementation methods_javascript skills

You can create files on the visitor's hard drive through the browser, because I first tried it and it worked. If you don't believe me, COPY the following code into an HTML file and run it again!

Copy code The code is as follows:

Did you find that the Autoexec.bat file on your C drive is missing? Haha, actually when that file is run, IE will remind you that the ActiveX control you are currently using is unsafe and ask you whether to run it, but since you are as eager as me to try out the effect, you will press [OK] without hesitation. .... In fact, this is implemented using FileSystemObject. If you want to know more detailed usage and examples, click here to download the Chinese documentation of JScript or buy a copy of <> You can also take a look at the examples compiled by Wuyou Script for everyone to learn. Let us first take a look at what attributes and functions are available, and then we will make some small examples of some functions

Open a file stream instance description BuildPath(path, file name) //This method will add to the given path Upload the file and automatically add delimiters

Copy the code The code is as follows:

CopyFile(source File, target file, overwrite) //Copy the source file to the target file. When the overwrite value is true, the file will be overwritten if the target file exists

CopyFolder(object directory, target directory, overwrite) //Copy the object directory to the target directory. When overwrite is true, the file will be overwritten if the target directory exists

Copy code The code is as follows:

Copy the code The code is as follows:

CreateTextFile(file name, overwrite) //Create a new file. If the file already exists, you need to set the overwrite value to true

Copy code The code is as follows:

GetParentFolderName (file object) //Get the parent directory name

Copy code The code is as follows:

GetSpecialFolder(directory code) //Get the paths to some special directories in the system. There are three directory codes: 0: Directory where Windows is installed 1: System file directory 2: Temporary file directory

Copy code The code is as follows:

GetTempName( ) //Generate a random temporary file object, starting with rad followed by some random numbers, just like some software will generate *.tmp during installation

Copy Code The code is as follows:

To Be Continue! There are still a few attributes that I haven’t written examples for. I will give them later. Do you think it will happen every time? Are you having trouble running? Or..., wondering how to run without asking? (Don’t use scripts to damage other people’s systems!)
Use JavaScript to create shortcuts to the file system
