I think you're confused about client vs server side code.  You can't execute CF code from javascript. Javascript runs on the client (browser) and CF runs on the server. Neither one knows anything about the other.  To communicate with the CF server from javascript you need to submit another http request, such as using ajax, submitting a <form>, etc...

What's your ultimate goal in english, not code?

The answer is ID: 37783271 -  you can't.

Client side code executes after server side code is finished. To run more server side code you must submit a new request.
