ruby on rails 3 - Rails3 - How to send Javascript Variable to a controller's action with the link_to helper?

Question

If i have the following javascript code

var myVar = 0;

function setNewValforVar(newValue){
    myVar = newValue;
}

and i'm calling setNewValforVar function n times

so when I click on a link it'd send myVar value to the controller action in a remote link like

<%=link_to "My Link",{:action=>"myAction"},:data=>''sval='+myVar',:remote=>true%>

I Rails 2.3.x I'd do this with

<%=link_to_remote "My Link",:url=>{:action=>"myAction"},:with=>"'sval='+myVar"%>

and i was getting this on the controller's action with

params["myVar"]

how do I do this on Rails 3 with the link_to helper?

Answer 1

Rails 3 no longer supports this behavior. You will have to either create a form to submit the value, or modify the href of the link to include the value in the query string.
