Miscellaneous small jQuery plugins and code fragments

http://benalman.com/projects/jquery-misc-plugins/

This repository contains a collection of minor jQuery plugins which are too small, too simple, or just not exciting enough to require individual pages. More will be added as I find the time... and the code!

Visit the project page for more information and usage examples!

jQuery :attached, :detached selectors - Selectors that match elements currently attached to or detached from the DOM.
jQuery each2 - If you're going to use $(this) inside an .each loop, iterating over many thousands of elements, use this plugin instead. It's faster.
jQuery getClassData - If you're not yet using HTML 5 data- attributes, you can store basic data in an element's class attribute for easy retrieval.
jQuery getUniqueClass - For when you really need a unique classname.
jQuery htmlDoc - Get html, head and body in your $(html).
jQuery isjQuery - Determine if an object reference is a jQuery object.
jQuery loadAdScript - Load third party ad network scripts that use document.write into specific containers.
jQuery :nth-last-child selector - Works exactly like jQuery's built-in :nth-child selector, except that it counts from the end.
jQuery queueFn - Execute any jQuery method or arbitrary function in the animation queue.
jQuery scrollbarWidth - Calculate the scrollbar width dynamically!
jQuery selectColorize - Basic cross-browser colored select boxes.
jQuery serializeObject - Serialize a form into an object.
jQuery viewportOffset - Calculate left and top from the element's position relative to the viewport, not the document.

These once-misc plugins have been "promoted" to full projects:

jQuery replaceText - String replace for your jQueries!
jQuery throttle / debounce - Rate-limit your functions in multiple useful ways, great for event callbacks.
jQuery Untils - nextUntil, prevUntil, and parentsUntil traversal methods.
