Create a file in javascript

Question

I want to create a text file in javascript. I have tried this, but it doesn't work:

 var file_name=dir+'/aaa.txt';
 var fso = CreateObject('Scripting.FileSystemObject');
 var s = fsoo.CreateTextFile(file_name, True);
 s.Close();

I need to create an empty file to a path.

UPDATE1: I have also tried this, but doesn't work. Also I can not import System.IO:

 var file_name='aaa.txt';
 StreamWriter sw = new StreamWriter(file_name);
 sw.WriteLine("This is the line");
 sw.Close();

UPDATE2: I also have tryed to execute a unix comand that does 'touch file_name'. However this doesn't work either:

 var sys = require('sys')
 var exec = require('child_process').exec;
 var child;

 child = exec(\"touch\" + file_name, function (error, stdout, stderr) {
    sys.print('stdout: ' + stdout);
    sys.print('stderr: ' + stderr);
    if (error !== null) {
       console.log('exec error: ' + error);
    }
 });

Does anyone know how I should create a file in javascript?

Do you want to do this with a browser, and to write to the local filing system? The browser security model will stop you doing that, if so. — halfer

Are you attempting to run this in a browser? Or in server-side Javascript, in Node for example? — unwitting

This project on github looks promising:

https://github.com/eligrey/FileSaver.js

FileSaver.js implements the W3C saveAs() FileSaver interface in browsers that do not natively support it.

Also have a look at the demo here:

As I see this helps if you want to download(save locally) some file. I only need to create a file on a specific path (similar to touch file in batch).

Node.js has a library called FS FS Tutorial

You can easily create files using a built in function as so,

// include node fs module
var fs = require('fs');
 
// writeFile function with filename, content and callback function
fs.writeFile('newfile.txt', 'Learn Node FS module', function (err) {
  if (err) throw err;
  console.log('File is created successfully.');
});
