in IE, there is an additional method onbeforeunload, whatever string this returns is displayed in a popup wrapped in some 'built-in' text, cannot remember the text, but if its just IE, try the following

window.onbeforeunload=new Function('return \'The message I want the user to see\'');

 

by: ndixonPosted on 2005-07-29 at 03:31:19ID: 14553275

or even

<body onbeforeunload="return 'The message I want the user to see';">

never actually used it like this.

However it is important to note that both methods are called when a document is unloaded (navigated away from)

I usually use something like this

<script language="JavaScript">
  <!--
     var allowUnload = false;
     window.onbeforeunload = new Function('if(!allowUnload){return \'The message I want the user to see\';};');
  //-->
</script>

in each acceptable method of navigating away from the page i would then set the variable to true

<a href="#" onclick="allowUnload=true;">
<input type="submit" value="save" onlclick="allowUnload=true">

This is also triggered when refreshing the page.  But for me this falls into the category of methods which are unacceptable.

I'm pretty sure that what you want isn't possible - you can't prevent users from closing windows with scripting (spammers would love it if it were otherwise)

 

by: ndixonPosted on 2005-07-29 at 05:11:56ID: 14553824

dorward is right, stricktly speaking it isn't possible, my code for IE ONLY is as close as I've ever seen accomplished, there is ofcourse the undesirable possibilityof re-popping the window using the onclose event (I would not agree with or endorse this under any circumstances).

 

by: str_kaniPosted on 2005-07-29 at 21:07:54ID: 14560126

yes it not possible and more than this.... the onunload and onbeforeunload don't work on all the browsers. As you know not 100% of the surfers using IE!!!
