[Dynapi-Help] dynapi.onUnload question

[Jesse V. <je...@6t...>]

I have a page where the user is moving some layers around, and I want to 
make sure they save before they leave the page, so I'd like to promt 
them with a warning if the page is unloading and they haven't saved.

To do that, I need to stop the page from unloading if they want to 
save.  What can I do with dynapi.onUnload to stop the page from 
unloading?  Is it possible?

Thanks in advance,
    Jesse Vitrone

Problem: onUnload can't return false to stop the
location change like onSubmit can do.

Workaround: Check if the page should be unloaded in
onClick in all links and in onSubmit in all forms.
It's not elegant, but it works.

Code Example: We have a function check(), returning
true if the page should be unloaded, false otherwise.

A link:

<a href="p.html" onClick="return( check() );">

A form:

<form action="p.pl" onSubmit="return( check() );">

Thanks anyway.

well you could just inform MSIE users using the document.onbeforeunload  =
property (all msie's) which does return false, though this sort of =
negates the whole X-browser thing

It is possible in IE. Not in NS 4.x and unsure in Mozilla.

In IE:

<SCRIPT LANGUAGE=JavaScript FOR=window EVENT=onbeforeunload>
 var strMsg = 'Press Cancel if you wish to save your form before leaving\nIf
you press OK you will lose all unsaved information.';
 if (!top.ButtonClicked) {
  window.event.returnValue = strMsg;
 }
 </SCRIPT>
