Dynamic content with ajax (ruby on rails)

I use Rails and jquery and I need dynamic content with ajax.

But I do not know how to get the current user id

For example, URL: www.mywebsite.com/users/ 20

In my javascript file I need user id (20)

$.get("/users/<%= **20** %>.json", function(data)
      {

      }, "json");

Thanks in advance for your help.

Is there any other way to do this?

You can assign the value of the rails variable to the javascript variable in your view file, e.g.

"<% = javascript_tag" var userId = #{@current_user.id}; "%>"

and access to the variable inside the js file wherever you want.

Try <% = escape_javascript (params [: id])%> I'm not quite sure if escape_javascript is needed or will help.
