title: Ajax Error: Console says - POST is not defined
body: <p><strong>I have written the following jQuery code:</strong></p>
  
  <pre><code>$('#Submitter').click(function(f) {
  
      x = $('#link').serialize();
      $('body').append(x);
      $.ajax({
          type:POST,
          url:"engine.php",
          data:x,
          success: function(i){
              console.log(i);
              $('#i').html(i);
          }
      });
  });
  </code></pre>
  
  <p>Each time after clicking on the <code>&lt;input id="Submitter" type="button" value=Submit&gt;</code> element, Firefox's console displays the error: <strong>ReferenceError: POST is not defined</strong>.</p>
  
  <p>Where is the issue and how to resolve this issue?</p>
  
  <p>Thank you.</p>
