PrototypeXtensions adds additional components to Prototype.js and Script.aculo.us, two of the most popular and widely used JavaScript frameworks/libraries available. While these are extremely useful tools for creating visual effects, UI improvements, and Ajax methods, the creators of PrototypeXtensions realized a need for additional components. The library is currently at version 0.1.2 and is released under MIT License. There are three main categories of additions, or extensions, that are added by this library with specific features within each category. I have listed a basic feature overview below.

Features

There are detailed explanations and examples for each feature available so be sure to check out the website for more detailed features and information. You can download the current release in the original uncompressed form or download the smalled Minified and Gzipped version.

The Lightbox Clones Matrix lets you easily compare different lightbox clones in a table format. The table, or matrix, lists many of the features for each of the options and compares them side by side. Using jQuery to create the sortable table, the comparison matrix is very fast and easy to use. There are comparisons for 46 lightbox clones comparing seven different features. You have the ability to sort and/or filter by each of the seven features as well as the library type.

The filters include jQuery, Prototype, Mootools, YUI, "Can display images", "Can group images into sets", "Can display inline elements", "Can display iframes", "Can fetch content via Ajax", "Can display Flash", and "Can display various Video objects". There are icons to help you visualize the different features and easily sift through them.
