title: How to define Global Arrays?
body: <p>Code example:</p>
  
  <pre><code> &lt;script&gt;
        var data = new Array();
        data[0] = 'hi';
        data[1] = 'bye';
   &lt;/script&gt;
  
   &lt;script&gt;
        alert(data[0]);
   &lt;/script&gt;
  </code></pre>
  
  <p>This gives the following error: <code>data is not defined</code></p>
  
  <p>How do you make something like this work? Especially if the first <code>&lt;script&gt;</code> block is being loaded on the page by ajax, and the second block is working from it.  jQuery solution is acceptable.</p>
