Hello,
Is exiting a possibility to forbid the click on the close cross ?
Otherwise, can we put a js treatment in order to don't lose the informations
on the form ?

Thanks, Skot.

No.

Firefox and Mozilla support 'window.onbeforeunload' (though it doesn't 
seem to have made it into the on-line documentation yet) that allows you 
to prompt a user to not close a window.


  <script type="text/javascript">

  window.onbeforeunload = function() {alert('hi'); return false;};

  </script>

A beforeunload listener should return a string. This string will be 
displayed in a dialog box that asks whether the user wishes to navigate 
away from the current document. So,

   window.onbeforeunload = function() {return 'Hi';};

would be more appropriate.

You can't cancel the event programatically; the whole point is for the 
user to handle it.

Thanks Mike.

I couldn't find any documentation on the Mozilla site (it seems to be a 
fairly recent inclusion), the Microsoft doco wasn't very clear - their 
example used window.event.

Hopefully the following is better:


  function savePrompt()
  {
    var unsavedData = true;

    // Do some test to determine if there is unsaved data
    // if unsavedData = true, message is shown
    // if unsavedData = false, navigation is not interrupted

    if ( unsavedData ){
      var message = 'You have unsaved data.'
                  + '\nLeaving this page without saving'
                  + ' will cause the data to be lost';
      return message;
    }
  }

  window.onbeforeunload = savePrompt;
