How to Make a Navigation Button List Button Throw a Warning Message

Question

Hello All,
My application is using a button list, which gives the user the option of going around in the application. My newest requirement is when the user clicks on the Home button, I want to throw a Warning message telling the user that they must save before they can click on the home button. If they click cancel, then the user will stay on the current page and click the save button. If they click ok, then I want them to be able to goto the home page.
Should I put this in the list user defined attribute, if so what do I put. This does not need to be a conditional display.
Thanks,
Mary

Answer 1

I'd have the button calling a javascript function along the lines of:
<script type="text/javascript">
function confirmExit() {
  if (prompt("Are you sure you wish to exit without saving")) {
    redirect("Link to home page");
  else {
    /*Do nothing!*/
</script>To do this, have the button url link as javascript:confirmExit();
