In a nutshell; I wrote a simplistic chat application for a buddy and me to use. When the window running the application does not have the focus (minimized or behind other windows) and a message comes in, I want to change the windows title bar to serve as an alert. Exactly like Google's chat application does in GMail.

Everything works flawlessly in Firefox and Chrome but not in IE7 (haven't tested 8).

This is the code I am using to determine if the window has focus. Can this be written differently to also work in IE? Also, I'm open to any other approaches to accomplish the same thing. Many thanks in advance.

  $(window).bind("blur", function() {
    hasfocus = false;
  });

  $(window).bind("focus", function() {
    hasfocus = true;
  });
