Hi
I think you will find it is more difficult then you may think...
I am using the sample code from webtricks.com. Their default is two
selects - what I need to find out is where to add javascript and coldfusion
to build arrays for the third select box
This is the actual code for two selects, need to find out how to build in
the extra logic to get three selects working on the same approach as below?
This is where I am having trouble.... and would appreciate some help please
<script language = "JavaScript">
<!--
// For each state, create an array to hold the area codes.
// Each state array will be identified by the two-character state
abbreviation
<cfoutput query="GetStates" group="State">
// Create the array
StateArray#StateCode# = new Array();
<cfset i = 0>
// Populate the array
<cfoutput>
<cfset i = i + 1>
StateArray#StateCode#[#i#] = #AreaCode#;
</cfoutput>
</cfoutput>
// Function to populate the area codes for the state selected
function PopulateAreaCode() {
// Only process the function if the first item is not selected.
if (document.StateForm.StateCode.selectedIndex != 0) {
// Find the state abbreviation
var ThisState =
document.StateForm.StateCode[document.StateForm.StateCode.selectedIndex].val
ue;
// Set the length of the arecode drop down equal to the length of the
state's array
document.StateForm.AreaCode.length = eval("StateArray" + ThisState +
".length");
// Put 'Select' as the first option in the area code drop-down
document.StateForm.AreaCode[0].value = "";
document.StateForm.AreaCode[0].text = "Select";
document.StateForm.AreaCode[0].selected = true;
// Loop through the state's array and populate the area code drop
down.
for (i=1; i<eval("StateArray" + ThisState + ".length"); i++) {
document.StateForm.AreaCode[i].value = eval("StateArray" +
ThisState + "[i]");
document.StateForm.AreaCode[i].text = eval("StateArray" + ThisState
+ "[i]");
}
}
}
//-->
</script>
