close window automatically

**s00263668** · 08-01-2006, 02:44 AM

In my design, i want my Internet Explorer close automatically. Here is my code:

Code:

<script LANGUAGE="JavaScript">
function closePg(){
	window.close();
	return true;
}
</script>
<body onLoad="return closePg()"></body>

However, a pop up message was displayed after that. If nobody click the OK button, then the page will not close itself.

Yup. That will happen.

Only works in some browsers but, IE (the one that generated your confirm dialogue box) is one of them:

Code:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/1999/REC-html401-19991224/loose.dtd">
<html>
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<script type="text/javascript">
function closeIt(){
window.opener=self;
window.close();
}
</script>
</head>
<body onload="closeIt();">

</body>
</html>

Yes, but is it?? -*Insert maniacle laughter here

This is my personal favorite way to do this.

Code:

<script language="javascript">
onload=function closeIt(){
var cl=window.confirm("Close the window?")
if (cl) {window.opener=self;window.close()}
else {return closeIt()}
}
</script>

This does tend to tick off users

edit: don't use this, jscheuer1 is going to try to ban me for it!

Isn't that rather what the OP was hoping to avoid in the first place? :-\

**shachi** · 08-01-2006, 04:24 PM

Yea I think so too.

But, it forces you to close the window. When you hit "cancel" it returns the function.

**Twey** · 08-01-2006, 04:47 PM

Argh! I just read that. That's *awful.*

Recursion is not a good idea, especially when you don't control the level to which it will recurse

Every time the user clicks "Cancel," the function is run again, but the original call will still be in memory, since it won't return until the child does. That means that by the time they've clicked "Cancel" twenty times, you've got twenty-one copies of the function running, all at once.

Of course, if the user panics and just holds down enter, you could end up with 200+ copies of this function running -- a sure way to bring a monolithic system to its knees.

Whatever you do, do not use that code.
