Need iframe to change onbeforeunload function of parent window 1

tcstom · Jul 16, 2007

I have an iframe which, in certain circumstances, needs to nullify the onbeforeunload event of its parent window. I thought I could just use

Code:

window.parent.onbeforeunload = null;

but this doesn't seem to work. Can anyone help? Before anyone gets huffy about the use of frames and IE-only events, I have my reasons!

Hi

Well, it is not standard, but [tt]onbeforeunload[/tt] works in Mozillas and Safari too. Regarding the reseting of [tt]onbeforeunload[/tt], seems to work only in Mozillas and Safari. At least for me.

I suggest to use a flag as a workaround.

Code:

<html>
<head>
<title>A</title>
</head>
<body>
<script type="text/javascript">
[red]var doit=true;[/red]
window.onbeforeunload=function(){[red]if(doit)[/red]alert('Bye')}
</script>
<iframe src="b.htm">
</body>
</html>

Code:

<html>
<head>
<title>B</title>
</head>
<body>
<script type="text/javascript">
[red]window.parent.doit=false;[/red]
</script>
</body>
</html>
