title: Can a jQuery $.post call itself again from the callback?
body: <p>The use case would be if the response it gets isn't what it wanted it can call itself again.</p>
  
  <pre><code>$.post(qrLoginAjax.ajaxurl, { 
      userID : '11234324'
  },function( response ) {
      if (response.userID != 'undefined'){
          //do stuff
      } else {
          // call $.post again
      }
  });
  </code></pre>
  
  <p>How would I do that?</p>
  
  <p>Thanks</p>
