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).

The basic framework of an Ajax-enabled web page. The following JavaScript shows how to send a request for an XML file and how to receive that request. Of course, in a real life scenario, you'll have to implement better error trapping and actually do something with the XML that gets returned.

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 swear filter script I wrote for my xanga blog. I don't know if it has any application anywhere else. This will replace the swear words listed in the array with the character defined in blank_char. This isn't perfect but it works pretty well.

Basically, you can dynamically ask the webpage to look at a current object's attributes/values or even change the object's attributes/values. As such, running this script on any browser of your choice should show what attributes your particular browser will allow for an object reference you typed in.

I use this function when passing an array to a function being called from setTimeout();

Add dragging to your div elements. just adding class="drag" to the div element will make it draggable.

Here i'm adding an example for a draggable dialog box

Just a little code to make a window in XUL

I think that the problem comes when you populate a DataGrid's dataProvider with data from a a remoting call, such as a RecordSet returned from AMFPHP. The remoting protocol doesn't remember the datatype of each database column, so once you get the RecordSet back to ActionScript everything has become a String. You could go to the trouble of casting every numeric column's contents in the RecordSet to a Number so that the DataGrid will sort those columns numerically (1, 2, 3, ...) rather than lexicographically (1, 10, 11, ..., 2, 20, ...)... or you could throw this quick little function in and tell it which columns you consider numeric. It will replace the default sorting behavior with one that casts to numbers before comparing, when dealing in the columns you specify. Pass it an array of the columns' indices and the DataGrid in question. Non-numeric strings in the columns you specify will get treated as 0 and left unsorted at the top.
