Working with inherited code, i am having some issue with jquery not loading the data and populatin the dependant select:
Code:
Code:
<script type="text/javascript">
$(document).ready(function() {
//first, detect when initial DD changes
$("#parent_select").change(function() {
//get what they selected
var selected = $("option:selected",this).val();
//no matter what, clear the other DD
$("#child_select").children().remove().end().append("<option value=\"\">Select Option</option>");
//now load in new options if I picked a state
if(selected == "") return;
$.getJSON("categories.cfc?method=getContactSubCategory&returnformat=json",{"ccatID":selected}, function(res,code) {
var newoptions = "";
for(var i=0; i<res.length; i++) {
//In our result, ID is what we will use for the value, and NAME for the label
newoptions += "<option value=\"" + res[i].csubid + "\">" + res[i].contact_subcategory + "</option>";
}
$("#child_select").children().end().append(newoptions);
});
});
});
</script>
<select id="parent_select" name="parent_select">

I cannot help you further until I get to a real computer tomorrow.
Have a look at the generated code. Javascript is case sensitive.
There should be some errors in the error console in chrome or Firefox with firebug installed

try:
for(var i=0; i<res.DATA.length; i++) {
//In our result, ID is what we will use for the value, and NAME for the label
newoptions += "<option value=\"" + res.DATA[i][0] + "\">" + res.DATA[i][1] + "</option>";

go to jsbeautifier.org and paste your JSON data. You will end up with:
The code above is what the "rs" variable has. Clearly the id and description you need for the <option> tags are in the "DATA" element. rs.DATA is an array that contains 5 elements/items. Thus,
rs.DATA[0] has the array
[3, "Tracking shows delivered but shipment not received", 1]
rs.DATA[1] has the array
[2, "Shipment is late", 1]
etc. Notice that on each of these arrays, the first element (index 0) has the ID for the value of the <option>. Also, the second element (index 1) has the text/description for the <option> tag.
Knowing this, if you want the id (3) for the first array, you need to use rs.DATA[0][0]. Likewise, to get the description "Tracking ...received", then you need to "access" it as rs.DATA[0][1].
On the code I posted, the variable "i" varies between 0 through 4 (inclusive), that's why you see:
If that still doesn't help you, I suggest you read up a little on JSON:
