Richard,
I appears that you're using JQuery so some of your questions might be
more appropriate on the forums over there, but a couple of things:
You need to pass the pound symbol in with your field so that JQuery
knows to specifically to look for an HTML element with that id
attribute:
$('#columnID').value=columnIDsArray;
If it's an existing javascript object variable, than there's no need
to quote it:
var columnID = document.getElmentById("columnId");
$(columnId).value=columnIDsArray;
I'm not exactly sure what the execution plan and fallback for JQuery
is when the pound sign is missing. Rey Bango would probably know, but
it's a good bet that this may be the problem. By using
"document.manageLookupForm.columnID.value" you are bypassing the
JQuery lookup of the object and accessing the DOM tree directly.
In any case, I'm not sure that populating your forms with javascript
on each step is the most effective or efficient way. Javascript and
a JQuery are wonderful for manipulating stuff after the document has
loaded, but server side code can make quick and accurate work of it
like in this (very basic) example of using the passed form structure
to quickly populate required fields:
<cfset reqFields = "name,author,title,text">
<cfloop list="#reqFields#" index="i">
<input type="hidden" name="#i#" id="#i#"<cfif structKeyExists(form,i)>
value="#form[i]#<cfelse> value=""</cfif>/>
</cfloop>
You can make short work of handling the passed variables and don't
have to rely on the browser to make sure the values are set correctly.
Just my 2 cents.
