link_to append parameter using javascript

Question

I know that in rails 2.3 there is :with option available with link_to form helper. The use of it is basically the append parameters to URL. But in rails 3.1 its not working, how can i append more parameters to path using link_to in rails 3.1. Here is how it worked in rails 2.3

I need to append to my path something i get from javascript.

<%= link_to "Edit", {:url => error_prone_teacher_students_path(@store), :remote => true, :with => "'id='+$('#id').val()", :method => :get}, :id => "load", :style=>"display:none;" %>

You can do like this

<%= link_to "Edit", error_prone_teacher_students_path(@store) + "?id=parameter", :remote => true, :method => :get, :id => "load", :style=> "display:none;" %>

Hope this helps!

Then I guess, u need to append it runtime. may be like this. I m assuming u r getting a value in a variable. `$("#link_id").attr(href, ($("#link_id").attr('href')+ "?id="+value))` – Abibullah Rahamathulah Jul 16 '15 at 10:44
