JavaScript实现3秒后页面自动跳

2023-01-31 03:01:34 javascript 页面
整个html页面代码如下,自己看吧:
 
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "Http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=GBK">
<title>易宝搜索</title>
</head>
<body>
 <h1>找不到匹配的结果</h1>
 <span id="totalSecond">3</span>秒后自动返回
</body>
<script language="javascript" type="text/javascript">
<!--
    var second = document.getElementById('totalSecond').textContent;
    if (navigator.appName.indexOf("Explorer") > -1)  //判断是IE浏览器还是Firefox浏览器,采用相应措施取得秒数
    {
        second = document.getElementById('totalSecond').innerText;
    } else
    {
        second = document.getElementById('totalSecond').textContent;
    }
    setInterval("redirect()", 1000);  //每1秒钟调用redirect()方法一次
    function redirect()
    {
        if (second < 0)
        {
            location.href = 'query.jsp';
        } else
        {
            if (navigator.appName.indexOf("Explorer") > -1)
            {
                document.getElementById('totalSecond').innerText = second--;
            } else
            {
                document.getElementById('totalSecond').textContent = second--;
            }
        }
    }
-->
</script>
</html>
