How do I run the system commands in javascript?

Question

I need to list all the files in the javascript such as \"ls\"??

Answer 1

Please give more information of your environment.

Unprivileged JavaScript in a browser can neither list files nor execute programs for security reasons.

In node.js for example executing programs works like this:

var spawn = require('child_process').spawn,
var ls  = spawn('ls', ['-l']);
ls.stdout.on('data', function (data) {
   console.log(data);
});

And there is a direct way to list files using readdir()
