Prevent user to perform any actions while page is loading

Question

I have a tabbed web application, and I also created caching of the images before page transitions, so when the user goes to a page, I make sure all the images are downloaded

Answer 1

I use:

$(window).bind('load', function() {
    // code here
});

Until the page is not completely loaded this event is not fired. So, there, you can call a function that unlock your page's elements.

Enjoy :)
