一个的404自动跳转首页代码，以WordPress为例把下面的代码添加到主题404.php文件内
<script language=’javascript’ type=’text/javascript’>
var secs = 5; //倒计时的秒数
var URL;
function Load(url) {
URL = url;
for (var i = secs; i >= 0; i–) {
window.setTimeout(‘doUpdate(‘ + i + ‘)’, (secs – i) * 1000);
}
}
function doUpdate(num) {
document.getElementById(‘ShowDiv’).innerHTML = ‘<h2>还有<span style=”color:red”>’ + num + ‘</span>秒后自动反回首页<h2>’;
if (num == 0) { window.location = URL; }
}
</script>
</head>
<body>
<script language=”javascript” type=”text/javascript”>Load(“http://www.qinkei.com”); //网址修改成你要跳转的默认首页</script>
<div id=”ShowDiv”></div>
</body>
