JSP中如何利用JS实现登录页面的跳转(JSP中如何利用JS实现跳转页面)
注:只是用到js中的setTimeout();具体使用方法:
setTimeout(函数名, 时间(毫秒));
setTimeout( ) 是属于 window 的 method, 但我们都是略去 window 这顶层物件名称, 这是用来设定一个时间, 时间到了, 就会执行一个指定的 method。setTimeout( ) 通常是与 function一起用.
样例:
1 <%@ page language="java" contentType="text/html; charset=UTF-8"
2 pageEncoding="UTF-8"%>
3 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
4 <html>
5 <head>
6 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
7 <title>Login the System Information.</title>
8 </head>
9 <body>
10 <h1 align="center">Login the System Information.</h1>

12 <%!String url = null;
13 String word = null;%>
14 <%
15 String tag = (String) request.getSession().getAttribute("tagToMBoard");
16 if (tag == "0") {
17 url = "/HRuinger/index.jsp";
18 word = "你输入的用户信息不正确,请你核对后重新输入!正在为你转到登录页面.";
19 }
20 if (tag == "1") {
21 url = "/HRuinger/messageBoard.jsp";
22 word = "你输入的验证码不正确,请你核对后重新输入!正在为你转到登录页面.";
23 }
24 if (tag == "2") {
25 url = "/HRuinger/messageBoard.jsp";
26 word = "你已登录,欢迎你的使用!正在为你转到主界面.";
27 }
