<!--复制自动版权-->
<script language="javascript" type="text/javascript">
jQuery(document).on('copy', function(e)
    {
      var selected = window.getSelection();
      var selectedText = selected.toString().replace(/\n/g, '<br>');  // Solve the line breaks conversion issue
      var pageInfo = '<br>---------(^-^)---------<br>'
                + '本文章原文链接<br>'+ document.location.href
                + '<br>来源：菜鸟建站(www.newbii.cn)<br>';
      var copyHolder = $('<div>', {id: 'temp', html: selectedText + copyFooter, style: {position: 'absolute', left: '-99999px'}});
        
      $('body').append(copyHolder);
      selected.selectAllChildren( copyHolder[0] );
      window.setTimeout(function() {
          copyHolder.remove();
      },0);
    });
