Force "respond_do" format

I am using RJS with Prototype. In my controller I have this code:

def method_name
    respo开发者_如何学编程nd_to do |format|
        ...
        format.html
        format.js
    end
en

Is it possible to force the "respond_do" to use the 'format.html' whether or no the request is HTML or JAVA? If so, how to do it?

Don't use respond_to. Just let the controller action return or call render if you want to specify a particular view.
