title: Issue with Inputs in jQuery
body: <p>Kind of new to learning jQuery, I wrote this script.</p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
      $(document).ready(function(){
          alert($("#myInput").value);
          alert($("#myInput").length);
      });
  &lt;/script&gt;
  
  &lt;input id="myInput" value="Hello, World!" type="text" /&gt;
  </code></pre>
  
  <p>I don't know why it is not why it always shows me:</p>
  
  <pre><code>undefined
  1
  </code></pre>
  
  <p>While the expected outptu is:</p>
  
  <pre><code>Hello, World!
  13
  </code></pre>
  
  <p>Please advice me. Thanks in advance.</p>
