Javascript to detect page changes...

[Victor]

I have a form and would like to pop-up a JavaScript alert reminding the user to click on
"save/update" before clicking on any other link/moving to the next page. The alert isn't
necessary if no changes were made on the page. Is this possible?

add onChange="setVar()" to all of your form elements, and onClick="return checkVar()" to all of your links.

<script>
<!--
changed = false;
function setVar(){
  changed = true;
}

function checkVar(){
  if (changed) {
  alert("You need to save your data!");
  return false;
  }
  return true;
}
//-->
</script>
