It is **impossible** to "use document.write java script (sic) to write the variable to a CF variable". Cannot be done. Why? Because CF variables are only available on the server side, and are long gone figments of one's imagination by the time the HTML/JavaScript/CSS/etc. reaches the client side (the browser).
You can, however, use JavaScript to write a form field value or to directly POST/GET to/from a CFC once the page has loaded in the browser.
