例4:倒计时定时跳转
复制代码 代码如下:
<html>
<head>
<base href="https://www.jb51.net/<%=basePath%>">
<title>My JSP 'ds04.jsp' starting page</title>
<span>3</span>
<a href="javascript:countDown"> </a>秒后自动跳转……
<meta http-equiv=refresh content=3;url= '/ds02.jsp'/>
<!--脚本开始-->
<script language="javascript" type="">
function countDown(secs){
tiao.innerText=secs;
if(--secs>0)
setTimeout("countDown("+secs+")",1000);
}
countDown(3);
</script>
<!--脚本结束-->
</head>
例6:
复制代码 代码如下:
<head>
<meta http-equiv="refresh" content="2;url='b.html'">
</head>
例7:
复制代码 代码如下:
<script language="javascript" type="text/javascript">
setTimeout("window.location.href='b.html'", 2000);
//下面两个都可以用
//setTimeout("javascript:location.href='b.html'", 2000);
//setTimeout("window.location='b.html'", 2000);
</script>
例8:
复制代码 代码如下:
<span>2</span>
<script language="javascript" type="text/javascript">
var second = document.getElementByIdx_x('totalSecond').innerHTML;
if(isNaN(second)){
//……不是数字的处理方法
}else{
setInterval(function(){
document.getElementByIdx_x('totalSecond').innerHTML = --second;
if (second <= 0) {
window.location = 'b.html';
}
}, 1000);
}
