Code submission - "copy" code

Coffeescript:

    # snippets of clipboard-handling code taken from
    # http://codebits.glennjones.net/editing/setclipboarddata.htm
    # Note that this works only in Chrome. Firefox and Safari need a piece of
    # text to be selected in order to even trigger the copy event. Chrome does
    # enable clipboard access instead even if nothing is selected.
    # There are a couple of solutions to this - one is to keep a hidden textfield that
    # handles all copy/paste operations.
    # Another one is to not use a clipboard, but rather an internal string as
    # local memory. So the OS clipboard wouldn't be used, but at least there would
    # be some copy/paste working. Also one would need to intercept the copy/paste
    # key combinations manually instead of from the copy/paste events.
    document.body.addEventListener "copy", ((event) =>
      if @cursor
        selectedText = @cursor.target.selection()
        if event.clipboardData
          event.preventDefault()
          setStatus = event.clipboardData.setData("text/plain", selectedText)

        #log('setData: ' + setStatus);
        if window.clipboardData
          event.returnValue = false
          setStatus = window.clipboardData.setData "Text", selectedText

        #log('setData: ' + setStatus);
