Restrict onbeforeunload event from being fired

Question

I am using Ajax tabcontainer. i want to restrict the onbeforeunload event being fired on Ajax TabContainer. On click of one of the tab of TabContainer i am getting the alert/confirm message box which i have return in Onbeforeunload function.

The alert occurs because on tab click i have written C# code so postback occurs.

$('a').click(function() {
                window.onbeforeunload = null;

});

window.onbeforeunload = function() {
                return 'Pending changes will be lost unless they are saved first.'
                'Are you sure you want to leave this page?';
            };

Thanks in advance

Hi Try like this $('a').click(function() { event.preventDefault(); window.onbeforeunload = null; }); Regards Iftikar

onBeforeUnload event will be called everytime on postback. So what i am proposing will not look so good but that is how you have to handle it var isTabClicked = false; $('a').click(function() { isTabClicked = true; }); window.onbeforeunload = function() { if(!isTabClicked) { return 'Pending changes will be lost unless they are saved first.' 'Are you sure you want to leave this page?'; } };
