Tab Scope is a very handy Firefox add-on that shows a pop-up preview of a tab's contents when hovering over a non-selected tab...oh, a picture probably will say it better: The developers have clearly put a huge amount of work into Tab Scope over the years and have largely got it right, and in addition to a preview image, there's a couple of controls like back, forward, refresh in the pop-up itself. After using Tab Scope version 0.3 with the fx4 theme for a couple of weeks, there's a few things on my wish list, however: Left-clicking on the actual preview image...

Had a gnarly problem this afternoon, while trying to set focus to a control in an IFRAME. Using JQuery, I had created the IFRAME with the JQuery plugin ThickBox. ThickBox provides functionality that can simulate a modal dialog using an IFRAME, loading a page from a URL into the IFRAME (check out the demo here - scroll down to "Inline Content"). The page loaded inside the IFRAME contained code to set the focus which was actually being called, but after the page loaded something else was stealing the focus. I began to look at the javascript code in...

It's not very often that I do a link blog, but I've come across so many great JQuery links in the past week or so that I had to get them all down:   First off, the JQuery UI wiki has a great list of Essential Controls, both in the UI library and links to plugins (via Delicious Popular Bookmarks). Steve Reynolds' Top 10 JQuery Plugins for Form Usability covers 10 JQuery plugins that make web forms more usable, such as tooltips, user name availabilty checker, and validation. Speaking of tooltips, BeautyTips...

I've been playing with the excellent JQuery JavaScript library for a while now. Recently I came across a technique for fading in and out two images based on mouse over and mouse out; and I wanted to see if I could create a fade-in and fade-out hover effect without the images. It's a testament to the robustness and flexibility of JQuery that I could do this in so little code, with so little knowledge. Admittedly my first go can be CPU-intensive, however the code is short and sweet - include JQuery and JQuery UI, mark your elements with a CSS class...
