ColdFusion is server side. Once the page loads, CF is done.
JS is client side. You can't reference CF code inside of JS after the
page loads (not without getting AJAX-y).
you can create JS variables with CF:
<script type="text/javascript">
var myFoo = "<cfoutput>#myQuery.foo#</cfoutput>"';
</script>
if you view the source of that page after it loads, you'll see the JS
is valid. it's identical to using CF to create HTML.
However, once the page loads, you can no longer rely on CF to create
any client side code.
To do what you want, you'd use CF to create a JS array and your
onclick would use that array.
