这个地方，你生成这种格式就可以了

<div class="n_pi_t otimecountdown" res="10000"></div>
--------------------编程问答-------------------- Microsoft JScript 运行时错误: 缺少对象

还是不行 --------------------编程问答-------------------- 你调试下是哪行报告的错误。
另外，你直接把我i的代码存成aspx看是否正常 --------------------编程问答-------------------- 另外，你的代码比较多，没法直接对你的代码测试
