Hi,

if I understood you, simply in javascript you can say :
document.locati on = "http://example.com".
this is an assigment, so document.locati on is read/write property !!
in any case, and same for the window.location = "http://www.example.com ".
why the onpropertychang e event is not fired !!
could you please explain more .

onpropertychange event is not fired when you change document location
Hello ,
I have attached the onpropertychang e event to my document as :
[CODE=javascript]// the handler function
function propertychangeH andler(){
alert('property change event...');
}
document.onprop ertychange=prop ertychangeHandl er;
// now, when I change the document.locati on as :
document.locati on="http://www.google.com" ;... -
what about method overriding such as :
window.confirm = function (){ }
I have tried that, but still the dailog box appears .
but are there any other ways to detect that this window will be unloaded . of course without any alerts or confirm boxs .
