Thread: dependent select - ajax issues

I am unable to get Louie's select box magic working. I've added the closing script tag and replaced `s with ' as well as updated the include_once link to page2.php
everything else is cut and paste and I can not get his script to work.

the select boxes both appear but upon selecting an option the second box does not change unless I use the submit button. I have a particular need for dynamic select boxes as I have 3-15 options in the first select and up to 70 options in a second select depending on the option in the first and don't want to cary all that code in the doc... but alas, I'm stumped even after reading several articles and posts on the subject.

http://netviper.com/test/page1.php <-- currently working on it

first fix this line in your javascript:

Code:

 if ( xmlhttp_obj.readyState == 4 && xmlhttp_obj.status == 200 ){  
 
//to
 
 if ( xmlhttp_obj.readyState == 4 && xmlhttp_obj.status == 200 ){

than get back to me on this as is due to copy and paste issues

you da man... I could swear I fixed that after reading your post from last year.
It appears to be working though I need to modify it now to have two select boxes dependent on the and not hierarchal (sp?) and then connect it to my
db

any cautions with the above before I proceed?

either way, Thank You!!

Cautions? - Sanitise the QS before accessing the DB

That is a very simple sample and can do the magic alright, but there a very good frameworks out the that could do more than one AJAX call simultaneously which is very handy - like Yahoo YUI

More than one Ajax call simultaneously??

How come the ajax is refreshing the entire div and not just the contents of the select box?
