Getting alert when closing the browser

ravula2000 · Sep 16, 2002

Can I generate an alert box when I try to close the window that is started by browser, not by window.open() method?
Iam thinking to trap unload event of the window.. but dont know where to trap..
Can some body suggest me..?

Thanks

Hi,
But Iam not able to prevent window from closing..
After the window is closed Iam getting that message.
Can you please suggest some thing..

Thanks

use the

Code:

onbeforeunload

event instead of

Code:

onunload

, you'll be able to cancel closing by making your function return false or by typing

Code:

event.returnValue=false;

in your function.

Hi,
I got one more problem. When I refresh the browser Iam getting this alert box generated from onbeforeunload event.
Can I prevent this? I want to get only this message when I try to close the window.

Thanks

The only thing you can do is detecting the reason for wich your page is being unloaded. If it's by F5 (that you can catch by "onkeyDown" event on the body), put the showMessage global boolean to false. Then in the onbeforeunload method, do not affect anything to the returnvalue if showmessage = false.
This way doesnt prevent your message from being shown if the user clicks the "refresh" button.

NOTE: the onbeforeunload event is also raised as soon as the user clicks on a link that changes current page. so you'll have to do the same thing for all your links. Water is not bad as soon as it stays out human body ;-)

Hi Targol,

Thanks

I managed to do it by this code :

Code:

<script language=&quot;Javascript&quot; type=&quot;text/javascript&quot;>

var showMessage=true;
	
function testerTouche() {
	var valTouche = window.event.keyCode;
	alert (&quot;valtouche =&quot; + valTouche );
	if (valTouche == 116) {
		showMessage=false;
	}
	return false;

</SCRIPT>

</head>

<body onkeydown='testerTouche();'>
...
</body>

But only the thing is in this key down event if keycode=116 then I want to prevent the unload of the document.. not showing a message.
Is it possible?

Thanks

You can't stop page refresh, function key presses can't be canceled but once you've set your showMessage boolean to false, let the user refresh the page without message. Water is not bad as soon as it stays out human body ;-)
