    <SCRIPT language=JavaScript>
    function runCode()  //定义一个运行代码的函数,
    {
     if(1 == arguments.length)
      try{event = arguments[0];}catch(e){}
      var code=(event.target || event.srcElement).parentNode.childNodes[0].value;//即要运行的代码。
      var newwin=window.open('','','');  //打开一个窗口并赋给变量newwin。
      newwin.opener = null // 防止代码对论谈页面修改
      newwin.document.write(code);  //向这个打开的窗口中写入代码code,这样就实现了运行代码功能。
      newwin.document.close();
