title: Updating values on page without refreshing in Node.js
body: <p>I am trying to update values on my page when I user selects what they want to filter but I do not want to refresh the webpage constantly. As an example, think of a real estate website where you filter based on location and the types of housing come back with the number (e.g., apartment [4] townhouse [0] studio [5]). The types of housing will always be there but its the numbers I am interested in updating. When ever you change the filter, new numbers are popping up. What I am doing is filtering questions based on topic, subject etc. </p>
  
  <p>Is there anyway to use this in node.js? What I have working so far requires the page to refresh.</p>
  
  <pre><code>$.ajax({
      type="POST",
      url: "/user/calculatequestions",
      data: { 
           filter date here... },
      success: function () { },
      error: function () { }
  });
  </code></pre>
  
  <p>The '/user/calculatequestions' goes through an app.post and renders a new page with new variables.</p>
  
  <p>Thanks in advance,
  S</p>
