Smile

6y5.3k.NET

I have a website with mutliple tabs and with multiple menu items with a master page.How to know when the browser/tab is closed.I need to close a thread on browser close.

I Haved tried this event

"text/javascript">
window.addEventListener('beforeunload', function (e) {
e.preventDefault();
e.returnValue = '';
});

This event is getting invoked when i am moving from one tab to other and even from one menu item to other.I want to know only when the the browser/tab is getting closed.

Hey try this
"ConfirmClose()" onunload="HandleOnClose()">

var myclose = false;

function ConfirmClose()
{
    if (event.clientY < 0)
    {
        event.returnValue = 'You have closed the browser. Do you want to logout from your application?';
        setTimeout('myclose=false',10);
        myclose=true;
    }
}

function HandleOnClose()
{
    if (myclose==true)
    {
        //the url of your logout page which invalidate session on logout
        location.replace('/contextpath/j_spring_security_logout') ;
    }
}
