javascript - Using JQuery to bind "focus" and "blur" functions for "window", doesn't work in IE

Question

I need to use JQuery like the follwoing:

var focusFlag = 1;
jQuery(window).bind("focus", function(event)
{
focusFlag = 1;
});

jQuery(window).bind("blur", function(event)
{
focusFlag = 0;
});

Does anyone know why this doesn't work for IE?

Answer 1

Just to have the right answer here:

$(function() {
    $(window).focus(function() {
        console.log('Focus');
    });

    $(window).blur(function() {
        console.log('Blur');
    });
});

Note that in FF and IE the "Focus" event fires on ~document load, while in Chrome it only fires if the window had lost focus before and now it has regained it.
