title: Issue with ascii keycode in javascript
body: <p>I'm seeing a wierd issue in javascript, or maybe it's because javascript is new to me.</p>
  
  <p>I am trying to allow some action if onkeypress, but only when alphanumeric or special character is pressed. This is my code:</p>
  
  <pre><code>if(e.keyCode&gt;=32 &amp;&amp; e.keyCode&lt;=126 ){
      alert(e.keyCode);}
  }
  </code></pre>
  
  <p>It does not alert if I press any special character key like <code>{,]&gt;.</code> am I missing anything here? </p>
