jQuery/Ajax - Redirect to another page after succes message

Question

I want to redirect the user after filling up the contact form and the success message appears.

Here's the HTML code:

<div id="wpm_download_1" style="display: inline;">
   The link to the file(s) has been emailed to you.
</div>

and here's the JavaScript I'm trying:

function() { 
      var isDownloaded = jQuery('#wpm_download_1').text(); 
        if (typeof obj.isDownloaded != 'undefined'){
            window.location = 'http://google.com';
        }

    }

Basically, I want to redirect the user when this message appears after sending form data through AJAX:

The link to the file(s) has been emailed to you..

Solution

Alright, after trying hard I just came up this and it worked:

jQuery( document ).ajaxSuccess(function( event, xhr, settings ) {
  window.location.href = 'http://google.com';
});

Becuase, I wanted to be redirected after the successful AJAX request is complete.
