页面跳转

huangwenquan123 2010-01-25 01:51:42

在一个页面中有两个div，d1,d2
其中d1，是用来登陆的，d2隐藏
登陆成功后d1隐藏，d2显示，然后d2会在自动跳转到另一个页面
可是问题来了
d2刚开始时是隐藏的
可是隐藏的时候它还会继续执行跳转的代码
时间一到，不管我有没有登陆都直接跳转过去
该怎么办？

<head runat="server">

    <title>无标题页</title>

    <style type="text/css">

        body

        {

            font-size: 9pt;

        }

    </style>



    <script type="text/javascript">

        var i=4;

        function Ref()

        {

            if(i>0)

            {

                i--;

                document.getElementById("d2").innerHTML="登陆成功,三秒后跳转到个人管理"+i+",如果未跳转,<a href='Manage.htm' style='color:red'>请点击</a>";

            }

            else 

            {

                 //var ref = document.getElementById("a1");

                 //a1.click();

                 location.href="Manage.htm";  

                 document.getElementById("d2").innerHTML="登陆成功,三秒后跳转到个人管理"+i+",如果未跳转,<a href='Manage.htm' style='color:red'>请点击</a>";

                                 

            } 

        }  

            setInterval("Ref()",1000);
