ColdFusion runs on the server. JavaScript runs on the client. By the time
the browser has rendered the page, ColdFusion has done its duty and is
probably hanging out smoking a cigarette or using the little application
server room.
You can output CF variables to JS just like you do to HTML...
<script type="text/javascript">
var myName = "<cfoutput>#myName#</cfoutput>";
</script>
... but it's not a two-way conversation (much like my conversations with my
wife). If you want them to talk to each other, you need to introduce AJAX
into the equation.
So short answer is, no... a JavaScript variable can't be used to manipulate
a ColdFusion variable (but the converse works a treat), without utilizing
AJAX.
And maybe worth noting that the "language" attribute of the <script> tag is
deprecated in favor of "type".

I have failed as much as I have succeeded. But I love my life. I love my
wife. And I wish you my kind of success.
