JavaScript Need similar onload functionality after switching pages

I have some replaying functionality working by using Javascript and the window.onload function.

However when I go to some other page and then come back to the web application (with the onload function) it's no longer working since the page has not been refreshed (or loaded).

Is there a way I could refresh the functionality in the window.onload function if the user doesn't close off the page but it's in the background and after a while comes back and have it on focus?

Edit - bad question. After testing I realised this behaviour is with chrome only but works fine in IE and firefox. Sorry guys, I really thought it was a bug

Answer:1

The onload event should be fired when the user hits the back button. Elements not created via JavaScript will retain their values. I suggest keeping a backup of the data used in dynamically created element within an <input type="hidden"> set to display:none then onload using the value of the textbox to rebuild the dynamic elements to the way they were.

If you don't care about rebuilding the page and want to actually reload it, then you could do:

<input type="hidden" id="refreshed" value="no">

 <script type="text/javascript">
    onload=function(){
    var e=document.getElementById("refreshed");
    if(e.value=="no")e.value="yes";
    else{e.value="no";location.reload();}
    }
   </script>
