Well, no. You can't just assign the values to a form field and have CF
access it. You have to actually submit the form and have CF process it,
then do other stuff. For what you're seeming to want to do, that doesn't
seem like such a wonderful solution.
I'm not sure what you want to do with the height and width of the whatever
it is, but I would guess that you'll need to do it completely in JS /or/
find a way to calculate the size in CF.
What kinds of things are you trying to measure, and what are you trying to
do with those measurements?

: Yeah. That's what I figured. So I guess I can assign the javascript to a
: form field
: and then access the form field, right?
:
: <script language="JavaScript">
: var h = (eval(x#currentrow#).height);
: var w = (eval(x#currentrow#).width);
: document.forms[0].imgheight.value = h;
: document.forms[0].imgwidth.value = w;
: </script>
:
: <form>
: <input type="text" name="imgheight">
: <input type="text" name="imgwidth">
: </form>

: by form submission or url var. Remember ColdFusion is server
