Question

When a user have changed something in a form, then clicks on any link that will direct him to another page, I’d like to trigger a popup with a ‘Would you like to Save before leaving?’ option.

How can I do this?

Example:

 <script type='text/javascript'>      var shouldConfirm = false;      window.onbeforeunload = function() {          if(shouldConfirm) {              return 'You have made unsaved changes. Would you still like to leave this page?';          }      }  </script>   <input id='FullName' type='text' />  <script type='text/javascript'>      document.getElementById('FullName').onchange = function() {          shouldConfirm = true;      }  </script>
