unload function not working in Firefox and Chrome

Mar 19.2014

Hi

I am trying to handle window or browser close event with javascript to invalidate the session. Following is the code

window.onunload = function(e) {
e = e || window.event;
var y = e.pageY || e.clientY;
if(y < 0){
//call to java class to handle session
}
}

This snippet is working with IE but not in FireFox(version 23) and chrome(Version 33)

I tried onbeforeunload function which is working for all browsers but it is invoking even for refresh also which i don’t require.

Please suggest me to accomplish this issue..

thanks inadvance

@Sup3rkirbyMar 19.2014 — Playing with any unload scripts will typically leave you disappointed. Browsers all like to handle these sorts of things differently and there are a ton of restrictions.

But if you insist on using the events then I'd suggest taking a look at the [B]pageHide[/B] event for Firefox and Chrome. You'll want to add a check to make sure the event is supported, and then probably use the [B]addEventListener[/B] (and [B]attachEvent[/B] for IE8 and lower) to actually assign the event rather than directly assigning it to the window's event object.

I tried like below but still this pagehide not working in FF and Chrome

window.addEventListener('pagehide', exit, false);

function exit() {

//submitting form to java application

}

Success!
