如何计算页面的返回时间

转载：http://dev.mjxy.cn/a-How-to-calculate-the-return-time-of-the-page.aspx

服务器端开始计时：

ViewData["result"] = DateTime.Now.TimeOfDay.TotalMilliseconds;

页面最后调用脚本计算

<span id="times" title="<%:ViewData["result"]%>"><%:ViewData["result"]%></span>

    <script type="text/javascript">

        $(document).ready(function () {

            var today;

            today = new Date();

            var end = $("#times").attr("title");

            alert((today.getMilliseconds()-end)/1000);

    });
