    Javascript running in a browser doesn't have access to the underlying file system for security reasons, but this could be accomplished if you're talking about server-side JS (such as node.js). Are you? :) – chrisfrancis27 May 23 '11 at 12:22
  • @Chris - not strictly true. Permissions can be given and IE can use WSH FileSystemObject in HTA – mplungjan May 23 '11 at 12:25

Due to security restrictions you can not write local files using Javascript.

JavaScript on a web page cannot write a file to the local computer.

There is some scope for this in HTML 5, but it's not widely supported yet: http://diveintohtml5.ep.io/storage.html

For this, In your script section add:

try{var wsh = new ActiveXObject('WScript.Shell');} catch(err){}

This will promp user to enable Activex.
Then you can run any of the command using:

wsh.Run("notepad.exe"); //OR
wsh.Run("echo asdfasf sFAS  > a");

may be it works for you NOTE: i used ActiveXObject that means it works in IE only
