Javascript system folder file operations and parameter introduction _ javascript skills

Operations on javascript files include writing files, current directory files, reading files, deleting files, batch deleting, deleting folders, and deleting files in the current directory, if you are interested, refer to the previous section. net system operations, the implementation of the same function is very complex, I did not expect that javascript is so simple, so I searched the code on the Internet and made improvements.

The Code is as follows:

Function PathList (path ){
Var fso = new ActiveXObject ("Scripting. FileSystemObject ");
Var fldr = fso. GetFolder (path );
Var fd = new Enumerator (fldr. SubFolders );
For (;! Fd. atEnd (); fd. moveNext ()){
Sd = fd. item ();
WScript. Echo (sd. path );
// Write a file
WriteFile ("a. text", sd. path );
// Document. write (sd. path );
PathList (sd. path );
}
}
Function FileList (path ){
Var fso = new ActiveXObject ("Scripting. FileSystemObject ");
Var fldr = fso. GetFolder (path );
Var fd = new Enumerator (fldr. SubFolders );
For (;! Fd. atEnd (); fd. moveNext ()){
Sd = fd. item ();
Var fc = new Enumerator (sd. files );
For (;! Fc. atEnd (); fc. moveNext ())
{
WScript. Echo (fc. item ());
WriteFile ("B. text", fc. item ());
}
WScript. Echo (sd. path );
// Write a file
WriteFile ("a. text", sd. path );
// Document. write (sd. path );
FileList (sd. path );
}
}
// Current directory file
Function CurFileList (path ){
Var fso = new ActiveXObject ("Scripting. FileSystemObject ");
Var fldr = fso. GetFolder (path );
Var fc = new Enumerator (fldr. files );
For (;! Fc. atEnd (); fc. moveNext ())
{
WScript. Echo (fc. item ());
WriteFile ("c. text", fc. item ());
}
}
/*
Object. OpenTextFile (filename [, iomode [, create [, format])
Parameters
Object
Required. The object should be the name of FileSystemObject.
Filename
Required. Specifies the string expression of the file to be opened.
Iomode
Optional. It can be one of the three constants: ForReading, ForWriting, or ForAppending.
Create
Optional. Boolean value, indicating whether to create a new file when the specified filename does not exist. If a new file is created, the value is True. If the file is not created, the value is False. If not, no new file is created.
Format
Optional. Use one of the three-state values to specify the file opening format. If ignored, the file is opened in ASCII format.
Set
The iomode parameter can be any of the following settings:
Constant Value description
ForReading 1 open the file in read-only mode. This file cannot be written.
ForWriting 2 open the file in write mode
ForAppending 8 open the file and write it from the end of the file.
The format parameter can be any of the following settings:
Value description
TristateTrue open a file in Unicode format.
TristateFalse open an object in ASCII format.
TristateUseDefault: open a file by default.

}
