Well, you can pick up CF variables in Javascript easier than that. Just set them
directly!
<script>
var x = #cfvar#;
</script>
The server side Cold Fusion will spit out the above to the browser.
For reading Javascript variables in Cold Fusion you are correct, setting
form.element.value = 'X' will send it to CF on the next trip to the server.
Arrays and structures are no help because the client doesn't know about them.
