Submit a <form> without reloading

If you have a form on your PHP-enabled website and want to submit it without reloading the page,

1. Add this below the form:

    

   <div class="success" style="display:none"> Thank you for submitting. </div>
   <script type="text/javascript">
       if (typeof jQuery == 'undefined') {
           document.write('<script src="' + ( (location.protocol == 'file:') ? 'http:' : location.protocol ) + '//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js">\x3C/script>');
       }
   </script>
   <script src="send-form.js" type="text/javascript"></script>

2. Upload the contents of send-form.zip (2 KB) to your page location.

Enjoy!
