title: Get last part of CSV string
body: <p>Say I have a CSV string:</p>
  
  <pre><code>red,yellow,green,blue
  </code></pre>
  
  <p>How would I programatically select <code>blue</code> from the string using jQuery?</p>
  
  <p>The data is returned via an AJAX request from a PHP script rendering a CSV file.</p>
  
  <pre><code>var csv_Data;
  
  $.ajax({ 
      type: 'GET', 
      url: 'server.php',
      async: false,
      data: null, 
      success: function(text) { 
          csv_Data = text;
      } 
  }); 
  
  console.log(csv_Data);
  </code></pre>
