我是靠谱客的博主文静石头，最近开发中收集的这篇文章主要介绍倒计时-自动跳转页面，觉得挺不错的，现在分享给大家，希望可以做个参考。

<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://"
+ request.getServerName() + ":" + request.getServerPort()
+ path;
String errorMsg = (String) request.getAttribute("errorMsg");
response.setStatus(response.SC_OK);
%>
<!doctype html>
<html>
<script language="JavaScript">
var times=6;
clock();
function clock()
{
window.setTimeout('clock()',1000);
times=times-1;
document.getElementById('webRedictTips').innerHTML= times + "秒后自动跳转至登陆页面";
console.log(times);
}
</script>
<head>

<meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
<meta http-equiv= "Refresh" content= "5;url=/">
