While the FreshBooks widget is currently only for OSX’s Dashboard, a lot of the HTML element access and glitzy fades are pure jQuery, and should be portable to other widget facilities, and the FreshBooks website itself. It’s also nice to be able to use the same skills in widget creation as webpage creation.

And the skills you learn are re-usable, since jQuery implements CSS3-style selectors. When browsers get around to fully supporting them, you’ll already be at home. In addition, jQuery also makes dealing with XML (as returned by the FreshBooks API) and Ajax in general a whole lot easier!


jQuery also leads to shorter, more concise JavaScript. $(”#submit”) is so much easier to type than document.getElementById(“submit”), and infinitely more flexible when you want to, say, operate on all of the images in a page with $(“img”).
