Have you figured this out yet? I am looking for the same thing. How would you set a ruby variable inside a javascript method? Say something like this...

<SCRIPT language="JavaScript">

function submitform(nextQuestion) {   <% @nextQuestion = nextQuestion %>   document.form1.submit(); }

</SCRIPT>

Thanks

That's completely impossible - client side code cannot have server side effects (except of course via a request of some sort). If you are trying to change what the form submits, then a classic technique is to have a hidden field on the form that the javascript manipulates.
