Multiple Cascase Drop Down boxes

Hello Gobinathm,

Great stuff by the way.

Unlike the other gentleman that posted a threat regarding cascading drop downs, I am a beginner. I am currently using NetObjects Fusion 11 to develop my site, since I initially did not want to learn and write my own code. However aside from outside support, support from the NetObjects staff is nearly abysmal and I have resorted to getting involved with PHP for its dynamic page capabilities and clean integration with MySQL.

How would I modify the code to add additional cascading drop down boxes? A perfect example of what I'm trying to do may be found at this site:

First select a product, then you will see what I am asking about. Thanks in advance!

the example show is refreshs the page are you looking for somehting like that

Thanks for the quick response.

I am fine with the refresh shown in the example I sent you, however I know you mentioned that your method benefits users so that they do not have to wait for the page to reload.

I prefer your method over the page refresh method, however if it will require more time and coding, I will be okay with the page refresh method.

Thanks again.

Hello Gobinath,

I have successfully generated the cascading drop down boxes (thanks to your code). But now how do I capture the selected items from each combo box as variables to pass back to a PHP server and perform a DB query?

I have been experimenting with Ajax (using jQuery), but I am not having luck capturing the data. Here's what I have:


<script language="javascript" type="text/javascript" src="scripts/jquery-1.3.2.min.js">
</script>
<script language="javascript" type="text/javascript">
var MyJavascriptVariable = document.getElementById('selectloc');

$(document).ready(function()
{
$.post("ajax.php", { js: MyJavascriptVariable});
});
</script>


Ajax.php attempts to store the posted value in a php session variable. Finally when the variable is recalled, I get the following message:
"This is a PHP Page. The javascript value is: [object HTMLSelectElement]"

[object HTMLSelectElement]<=======this is my problem. Any ideas? Thanks!!!
