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.

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).

A simple Tooltip for you web pages with minimal code.

Here's a simple JavaScript solution to hide your e-mail from many spam scripts while still providing clickable hyperlinks to your visitors.

Web crawlers and visitors with JavaScript disabled will see: me [at] mydomain [dot] com. I've seen a lot of people that just leave it at this, but it seems a bit unprofessional in my opinion. With the following code, we can replace that with a fully functional hyperlink.

It works with Array types. The example is a simple list of numbers, but the array could contain anything; lists of strings, functions, DOM nodes, whatever. Unfortunately, a lot of things that seem like arrays in the DOM aren't really, so you can't shuffle the images on a page with just document.images.shuffle() all by itself.

Similar to Perl's CGI::escapeHTML(), though (because we can!) this adds it as a method to all String objects.

Strips all tags from any string.

Gives you control to perform actions when the control key and the mouse button is clicked in the same time. Something similar to selecting elements in Windows with ctrl+click.

Just change the event.ctrlKey to event.shiftKey to make it shift+click. If you don't get it don't worry the snippet contains the demo for shift+click too.

You may need to change the event.which though 1 = left click, 2 = middle click, 3 = right click(at least in firefox 1.5.0.5)
