title: Looking for MVC 3 tutorial with jQuery
body: <p>I am looking a tutorial that shows how to invoke an MVC action and pass parameters.
  I have a dynamic "comment box" which I need to save to database. 
  I want to use jQuery to send the comment data to a REST method that will handle it.</p>
  
  <p>I also need to refresh part of a page with data returned by MVC action.
  The data returned as JSON.</p>
  
  <p>I have seen tutoral from Scott Guthrie, but that uses postback.
  I need asynchronous communication through jQuery.</p>
  
  <p>Very simple and small tutorial will be very useful.</p>
  
  <p>Thanks</p>
  
  <p><strong>Edit:</strong>
  I will be using <code>$.ajax()</code> calls of jQuery</p>
