title: Object [object Object] has no method 'addEventListener'
body: <p>If I include the latest version of jQuery from the jquery.com site on my page:</p>
  
  <pre><code>&lt;script src="http://code.jquery.com/jquery-latest.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>then line 3 of the following code (pscript.js):</p>
  
  <pre><code>function init() {
      $("textbox").focus();
      $("textbox").addEventListener("keyup", _keytext, false); // line 3
      $("textbox").addEventListener("blur", _save, false);
      ...
  </code></pre>
  
  <p>produces the following error:</p>
  
  <blockquote>
    <p>pscript.js:3 Uncaught TypeError: Object [object Object] has no method 'addEventListener'</p>
  </blockquote>
  
  <p>I confirmed that this error goes away if the jquery script is not included. What am I doing wrong? How do I include jquery without the error?</p>
