Why file dialog box not opening?

Question

I am using following code to open a file dialog box, but nothing happens on button click(). What's wrong?

<input id="btnBrowse" name="btnBrowse" type="button" value="Browse" onclick="document.execCommand('SaveAs');"/>

Edited:

Any other way to open such a dialog on other browsers as well?

AFAIK, It will work only in IE. It is working on my IE 7 and not in FF.
