title: Copy to Clipboard in Chrome Extension
body: <p>I'm making an extension for Google Chrome and I have hit a snag.  </p>
  
  <p>I need to copy a readonly textarea's content to the clipboard on click in the popup. Does anyone know the best way to go about this with pure Javascript and no Flash? I also have jQuery loaded in the extension, if that helps any. My current (non-working) code is...  </p>
  
  <pre><code>function copyHTMLCB() {
  $('#lb_html').select();
  $('#lb_html').focus();
  textRange = document.lb_html_frm.lb_html.createTextRange();
  textRange.execCommand("RemoveFormat");
  textRange.execCommand("Copy");
  alert("HTML has been copied to your clipboard."); }
  </code></pre>
