As you've discovered, CF doesn't store variable names as case-sensitive
values. So, you won't be able to find out this information by looking at the
Form scope. Here are some options.
1. Look at the raw form data. You could do this with GetHTTPRequestData,
then reading the HTTP request body yourself. Yecch.
2. Rather than referencing the fields by name, use the elements array in
your CFSCRIPT block:
<cfscript>
for (var i = 0; i lt StructCount(Form); i = i + 1) {
WriteOutput("document.forms[0].elements[#i#].onclick =
EventHandler;");
}
</cfscript>
3. If you're setting the same event handler for all of the form fields, just
use JavaScript:
<script language="JavaScript">
for (field in document.forms[0]) {
field.onclick = EventHandler;
}
</script>
