Hello,

I was wondering if anyone knew of a great site or two, that helped with AJAX. (AJAX Tutorials). I have been looking, but I can only find the odd things, and they're not even tutorials, they're just source files, and I've already learned them now.

I hope to expand my knowledge of AJAX, so I can work it well with the things I work on.

Any links greatly appreciated.

Once you've used AJAX once, it's essentially the same to apply it to any situation. All you're doing is responding to an event, sending a request to the server, receiving the response, and then processing it appropriately.

True; its amazing that AJAX is such a powerful technique, yet quite easy to use.

Anyone know where to read some very basic AJAX tutorials? I am a bit of a javascript noob which won't help Something like the w3schools things would be nice

Of course without Javascript DOM knowledge you wont be able to easily manipulate the contents of the page.

http://www.quirksmode.org is good for that. ( W3C DOM > Introduction )

Heh turns out I had used AJAX before in my widget without realising

Here is a little simple thing I made: http:/www.coredesigns.co.uk/testingzone/ajax1/base.html

Instead of adding a new select menu, you should put a placeholder one in and add and remove the options from it as necessary.

Just a small issue from a usability perspective.

Yeah but it will have no options since it needs to wait for the first select menu to be filled. The use of CSS will help the layout, but i was just playing with the AJAX stuff for now.

Put a default option in it as "Please select an option", or similar, and set the select to disabled by default.

There any better: http://www.coredesigns.co.uk/testingzone/ajax1/base.html ?

Much!
