AJAX help for javascipt novice...

[admoore]

First, apologies for such a general question...
I am much more fluent in PHP, MySQL, etc....

AJAX appears to be exactly what I need in this case, though, so here goes...

I need to dynamically alter a web page's form such that making a selection from a <select> pull-down menu results in the page offering a second (and ultimatly a third) pull-down menu based upon the selections above it.
Am I on track attempting this w/ AJAX? If so, could someone help me out, please, as I have found no examples specific to what I am attempting.

TIA-

-Allen

You could very well use Ajax to retrieve the data from another location but what you are looking to do with the select boxes is refered to as dynamic select or dynamic list boxes. There are a couple of FAQs for dynamically adding/removing items from a listbox.

I have done linked dynamic select boxes in the past and found it easiest to pull the data down into arrays when the page loads then use javascript to dynamically alter the content of each box based on the selection in the previous box. If you have a HUGE number of possible options then you might want to use Ajax to go out and retrieve new selections as needed but it might not be necessary.


Stamp out, eliminate and abolish redundancy!

Ajax is ideal for what you want to do, but as theniteowl says, it might be over engineering - i guess it depends on how much you want to learn about .net etc.

The is a FAQ for dynamically creating drop down lists.

Have a look:
