title: AJAX form submission using ExtJS and ASP.NET MVC
body: <p>I am working with ASP.NET MVC and have a view page with a simple text box and button to accompany it. I want AJAX to submit the form when the user clicks the search button. The response (search results) will be returned and displayed in a content div on the same page.</p>
  
  <p>I have done this successfully with JQuery, but I need the same functionality in ExtJS.</p>
  
  <p>Here is the JQuery (the <strong>form id is #helpsearchbox</strong> and <strong>#helpcontent is the id of the content div</strong> I want the results to be loaded into):</p>
  
  <p><code></p>
  
  <pre>
      $(function() {
          $("#helpsearchbox form").submit(function(e) {
              $.post($(this).attr("action"),
                          $(this).serialize(),
                          function(data) {
                      $("#helpcontent").html(data);
                          });
              e.preventDefault();
          });
      });
  </pre>
  
  <p>Can someone please help me write the equivalent function in ExtJS? Many thanks!
