Visual Event. External code loading bookmarklet that visualises the JavaScript events hooked up to the current page, and lets you view the source code of the event handling function for each one. Only works for events added by jQuery, YUI or MooTools since those libraries maintain a cache of event handlers that they add, to work around the standard DOM’s omission of handler introspection.

jQuery 1.2.2: 2nd Birthday Present. The API stays the same, but there are some healthy speed improvements, a new way of adding custom events and (most importantly) .ready() now waits for the CSS to be ready in addition to the DOM.

Live Query jQuery plugin. Ingenious plugin that lets you register jQuery event bindings to be executed when a new element matching the provided selector is added to the DOM. Performance is kept snappy by only running the check after a jQuery DOM manipulation method has been executed (append, prepend, attr etc); it won’t notice elements added using regular DOM methods.
