title: how do I get the reponse text from ajax / jquery?
body: <p>Imagine I run this:</p>
  
  <pre><code>     $.ajax({
          type: 'POST',
          url: '/ajax/watch.php',
          data: {'watch':'aukcia', 'id':aukciaID},
          complete: function(responseText){
             alert(responseText);
          }
       });
  </code></pre>
  
  <p>Inside /ajax/watch.php, let's say I have this:</p>
  
  <pre><code>echo 'this is what I want';
  </code></pre>
  
  <p>And the alert(responseText) returns:</p>
  
  <pre><code>[object Object]
  </code></pre>
  
  <p>Instead of my text string that I need.
  Any help, please?</p>
