Cheap Turpentine: Ori Peleg's Blog: Prefetching JavaScript (or anything) with jQuery

(function($) { $.ajax({ url:"/js/file1.js", cache:true, dataType:"text" }); $.ajax({ url:"/js/file2.js", cache:true, dataType:"text" }); })(jQuery);

While users are logging into a web site, I thought why not prefetch some JavaScript files they'll be needing on the next page?

Web site que oferece o arquivo para download e a página para visualização de um preloader feito em JQuery !

There is always a minor problem when it comes to preloading image on a website. Nobody really has a full solution for it. There are a lot of preloaders available, but most of the time they only display the words: Loading page or have an animated image that spins. Why can't there be a nice loading bar of some kind? I've gotten a few request on how to make a preloader, or people asking me how to get all the images of a web page and preload them (even the images in CSS). This preloader has it all. Loading bar, custom animations and getting all images included in the web page.
