javascript实现错误页倒计时跳转

主要使用setInterval函数

<!DOCTYPE html>

<html lang="en" xmlns="http://www.w3.org/1999/xhtml">
<head>
    <meta charset="utf-8" />
    <title></title>
    <script type="text/javascript">
        var i = 5;
        var intervalid;
        intervalid = setInterval("fun()", 1000);
        function fun() {
            if (i == 0) {
                window.location.href = "http://www.baidu.com";
                clearInterval(intervalid);
            }
            document.getElementById("mes").innerHTML = i;
            i--;
        }
    </script>
</head>
<body>
    <p>还 <span id="mes">5</span> 秒跳转</p>
</body>
</html>
