Description of Fs.mkdir method used in Node.js _node.js

Method Description:

Create a file directory asynchronously. If the directory already exists, an exception is thrown.

Grammar:

Copy Code code as follows:

Fs.mkdir (path, [mode], [Callback (ERR)])

Because this method belongs to the FS module, it is necessary to introduce FS module (VAR fs= require ("FS") before use.

Receive parameters:

directory path that path will create

Mode directory permissions (read-write permissions), default 0777

Callback callback, passing exception parameter err

Example:

Copy Code code as follows:

var fs = require (' FS ');
Fs.mkdir (' Creatdir ', 0777, function (err) {
if (err) {
Console.log (ERR);
}else{
Console.log ("creat done!");
}
})

Modenum (mode, 511/*=0777*/),
