I use this in my AJAX as a quick way to get the Value of the selected item in a Select HTML object. If nothing is selected, it returns zero.
(May be basic to y'all, but maybe really usefull to someone else).

Fade an Element

This code allows you to set the "opcity" style attribute on a element without affecting it's content.

Just call the function for a specific element or to all elements of a given classname after the document loads.

Examples and advanced usage here...

These are some prototype methods to handle class names in html elements. As you all should know, a html element can have more than one class name.

This is part of my dom handling toolkit. Check it out and use it at will.

A simple, yet powerful (what a cliché) way of resgistering javascript keyboard shortcuts. Register any kind of keyboard shortcuts, and if applicable, override the browser default action.

Example usage and more info here:

Javascript Keyboard Shortcut Manager

Given a PHP array (even a deep nested array), returns a string representation of that array as JavaScript array. Useful when using PHP to output JavaScript.

This is an analog clock script designed to jump in place of a div element of class 'analogclock'.

The div tag is not replaced in this custom element, but instead is used as a pseudo-document to hold the clock itself. The 'hands' are implemented using arrays of generated divs.

I was actually inspired to write this widget because of an article on About.com's Javascript pages written by a guy named Stephen Chapman. His code was a mess, but I only discovered this after delving through two layers of 'unescape()' obfuscation.

The basics: You control the look of the numbers and the 'box' model of the clock using basic CSS. You control the clock's size (it will always be square) using the 'size' attribute.

The 'seconds', 'minutes', and 'hours' attributes are for the color of the 'hand's. 'numstyle' can be 1, i, I, or '.', each refering to a different type of face-numbering for the clock

The 'localzone' attribute tells the script to use the user's local time zone. If it's '0', 'false' or 'no', the clock will use the 'clockzone' attribute to determine what time it is (the clock zone is relative to GMT, so, for example, US Eastern is -5. The clock automagically figures out if we're in DST, so you don't have to.)

The 'city' and 'country' are for if you want to put in the city/country of origin for your clock. To be honest, you can put anything there.

Lastly, I designed my version of the clock to be able to not 'tick', i.e., work like the old-school analog clocks. If you want ticking, add 'tick=1' to the attribute list

As with all of my widgets, the idea here is that you can just include the .js file and start dropping in tags without needing to know any ECMAScript at all.

Additionally, for you ECMAScripters, I was very careful to keep my pollution of the global namespace to one class: analogClock.

Example of use:

This is a simple script to provide basic cross-platform XML request functionality in Javascript. It's meant to be the core component in any AJAX style framework. It is not an instantiable object, but instead is a namespaced microlibrary.

Calling is easy:
XMLRequest.GET(uri, query, callback, fallback)
uri: The location you're after
query: an associative array of form data to provide via the URL
callback: callback function of the form myCallbackFunction(objXMLHttpRequest), which is called upon successful (response = 200 OK) retrieval of the XML data
fallback: myFallbackFunction(objXMLHttpRequest), which is called upon failed (response != 200 OK) retrieval of the XML data.

XMLRequest.POST(uri, query, form, callback, fallback)
Similar, but does the query using the POST method. 'query' is the URL-appended data, still in associative array form, and 'form' is the same for the POST data.
