[Greasemonkey] Re: Output possibilities?

Here's a button to open a table from a generated overlay in a new tab. I've
tested it up to 400KB which for my no graphics table is more than enough.

function Cpy() {
  var cpy = document.createElement("img");
  cpy.setAttribute("src",
'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAABAAA'

+'AAQCAIAAACQkWg2AAAAAXNSR0IArs4c6QAAAARnQU1BAACxjwv8YQUAAAAgY0hSTQAAeiYAA'

D');
  cpy.setAttribute("style",
'height:16px;width:16px;padding-right:8px;padding-top:6px');
  cpy.setAttribute("title","Open in New Tab");
  cpy.addEventListener('click', function() {
      var html = '<html><head><title>Title</title></head><body><table>'
                 +document.getElementById('Rts').innerHTML
                 +'</table></body></html>';
      GM_openInTab('data:text/html;charset=UTF-8,' + encodeURI(html));
    }
  , true
  );
  return cpy;
}

And an example use:

  var cpy = new Cpy();
  div.appendChild(cpy);

|There are length limits, which are discussed on the first page

|The script, which @includes both the target page and the

|location.href value and do different things based on whether

|Unfortunately, the clipboard is not available to Greasemonkey

|I don't know that you can get to the file system, either --
