title: jQuery split problem
body: <p>I have a script, which returns value as an object. It can return text or numbers, like <code>'hello, goodbye'</code> or <code>'500, 900'</code>.</p>
  
  <p>When I try to use <code>split()</code> with this object, I catch an error:</p>
  
  <pre><code>TypeError: Object 'hello, goodbye' has no method 'split'
  </code></pre>
  
  <p>But I want to use split. What can I do?</p>
  
  <p>Seems the only way to convert this object into a string, how to do that?</p>
