[Javascript] Determining when a person leaves your domain

hi Matt,
The back button works because the page in the frame is loaded, not the
frameset.
But i can?t seem to catch the event when a user changes the address in the
addressbar though... (strange, shouldn?t that fire the onunload()?)

Better then nothing? I?m inclined to agree with Mike, let the user go when
he wants to leave.... Find another way to query the user about what you want
to know.

Anyway a bit of code to play with (to keep the customers happy :-)
The top.reloaded is to check if the reloadbutton is pushed.
(don't forget to put it in a frame)

<html>
<head>
<title>Untitled</title>
</head>
<script>
function clearBool(){
	if (typeof top.abandonBool == "undefined"){
		 top.reloaded=true
	}
	alert("clearBool:" + top.abandonBool)
	top.abandonBool=true
	alert("clearBool:" + top.abandonBool)
}
function setBool(){
	alert("setBool: " + top.abandonBool)
	top.abandonBool=false
	alert("setBool: " + top.abandonBool)
	top.reloaded=false
}

function getBool(){
	alert("getBool: " + top.abandonBool)
	if (typeof top.abandonBool != "undefined"){
		if ((top.abandonBool)&&(!top.reloaded)){
		  alert("abandoner!")
			 top.abandonBool=true
			 return false
		}else{
			 return true
		}
	}
}
</script>
<body onLoad="clearBool()" onunload="getBool()" >
bla bla<br>
<a href="javascript:setBool();this.location.href='subpage.htm'">internal
link </a><br>
more bla bla
<a href="javascript:this.location.href='externalpage.htm'">external link
</a><br>

</body>
</html>

That won't solve the problem Jessica is having with the browser
navigation buttons though.

A visitor would still see the confirm dialog when hitting the 'back'
button on the browser, since there's no way to tie an event to the
browser button which sets the value of the flag accordingly.
