There is no benefit from this link

 

You can't put Ajax in a form onsubmit like that.

http://www.alistapart.com/articles/userproofingajax/

 

you must return false at the end of the login function or the form will submit anyway, if this doesn't work try calling the login function from the onclick event of the submit button (once again you will still need to return false).

 

If javascript is not enabled the script will not run and the form will submit.
