• 1 When you say not working.. what is not working? Are you testing this in IE or any other browser? – Chandu Commented Feb 27, 2011 at 20:15
• i tried firefox and chrome and yeah no output! – dimazaid Commented Feb 27, 2011 at 20:16
• 1 Most browsers won't allow that. you could run the script from the console, and it would work. But not within a browser, unless the page itself is loaded with high trust. In IE there are security zones you can set for this; not sure about the other browsers. – Cheeso Commented Feb 27, 2011 at 20:18
• You could install a web server and then use XMLHttpRequest. Working locally has its disadvantages. – pimvdb Commented Feb 27, 2011 at 20:29
• The above will only work out of the box if you save the code with extension .HTA for html application – mplungjan Commented Feb 27, 2011 at 22:08

Make sure your browser has the right permissions to perform that kind of operation. Usually, browsers won't allow direct file system access by default.

Only IE supports ActiveXObject. Trying to use ActiveXObject on any other browser will fail because there is no such variable defined.

You need to either limit yourself to IE, write a browser plugin instead, or give up trying to get file system access on other browsers and proxy files through a server instead.

If you're running WAMP anyway, just use standard AJAX to fetch the file 22.txt from the server. The easiest way is to use jQuery, where the code would be:

$.get("22.txt", function(data) {
    alert(data);
}

You can search for how to do this without jQuery if you wish.
