A plugin that allows you to easily show a fancy tooltip when the user’s mouse hovers over (or, optionally, clicks on) any element you designate in your script.
A plug-in that attempts to determine the user’s intent… like a crystal ball, only with mouse movement! It works like (and was derived from) jQuery’s built-in hover.
4. jQuery Live Query Plugin
Live Query utilizes the power of jQuery selectors by binding events or firing callbacks for matched elements auto-magically, even after the page has been loaded and the DOM updated.
7. AJAX Calendar Widget with Optional TimeZone Support
Cross-browser text selection and modification plugin built on top of the jQuery library. Tested with Opera 9.5 (Windows) and Opera 9.6 (Linux), Mozilla Firefox 3.0 (Windows and Linux), Internet Explorer 7, Chrome 2.0 and Safari 4.0. Also works with jQuery 1.4.
