Are you sure you want to navigate away from this page

I have a web page - www.all-serials.net that contains a textbox and a submit button. When the user edits the text in the textbox and clicks another link (not the submit button) how do I display the 'Are you sure you want to navigate away from this page' popup message? I want some code or IDK.. My version is PunBB (punbb)

You would use the window.onunload event by attaching an event handler. The handler would ask the user if they wish to leave.

Can u give me the code pls and instructions how to put this code

Its not working

Try this:

Code:


(function(b){
  var f = function() { return confirm('Are you sure you wish to leave?'); };
  if(b.attachEvent) {
    b.attachEvent('onunload', f);
  }
  else {
    b.addEventListener('unload', f, false);
  }
})(document.body);


Nope.. its not working

I'm not sure if unload event is fired when clicking links to a new page. Only clicking back/forward and closing or reloading the page.

Might have to think of an alternative way.

I post ur code in java.. click in 1 topic, write something in quick reply and then click F5 to refresh the page.. and nothing.. i lost my message

its not working arww :@@@

And do you tick "In all pages"?
