使用Vue.js和Element-UI做一个简单登录页面的实例

最近了解到Vue.js挺火的,有同学已经学习了,那我心里痒痒的也学习了一点,然后也学了一点Element组件,就做了简单的登录页面。

效果很简单:

代码如下:

前端页面

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
<link rel="stylesheet" href="//unpkg.com/element-ui@1.3.6/lib/theme-default/index.css" rel="external nofollow" >
<script type="text/javascript" src="vuehttps://img.qb5200.com/download-x/dist/vue.js"></script>
<script type="text/javascript" src="element-ui/lib/index.js"></script>
<script type="text/javascript" src="jquery/jquery-3.1.1.js"></script>
<style>
.el-row {
 margin-bottom: 20px;
 &:last-child {
  margin-bottom: 0;
 }
 }
	.login-box {
		margin-top:20%;
		margin-left:40%;
	}
</style>
</head>
<body>
<div class="login-box" id="app" >
 <el-row>
	<el-col :span="8">
		<el-input id="name" v-model="name" placeholder="请输入帐号">
			<template slot="prepend">帐号</template>
		</el-input> 
	</el-col>
 </el-row>
 <el-row>
	<el-col :span="8">
		<el-input id="password" v-model="password" type="password" placeholder="请输入密码">
			<template slot="prepend">密码</template>
		</el-input>
	</el-col>
 </el-row>
 <el-row>
	<el-col :span="8">
		<el-button id="login" v-on:click="check" style="width:100%" type="primary">登录</el-button>
	</el-col>
 </el-row>
</div> 
</body>
<script type="text/javascript">
	new Vue({
		el : '#app',
		data : {
			name : '',
			password : ''
		},
		methods : {
			check : function(event){
				//获取值
				var name = this.name;
				var password = this.password;
				if(name == '' || password == ''){
					this.$message({
						message : '账号或密码为空!',
						type : 'error'
					})
					return;
				}
				$.ajax({
					url : 'login',
					type : 'post',
					data : {
						name : name,
						password : password
					},
					success : function(data) {
						var result = data.result;
						if(result == 'true' || result == true){
							alert("登录成功");
						}else {
							alert("登录失败");
						}
					},
					error : function(data) {
						alert(data);
					},
					dataType : 'json',
				})
			}
		}
	})
	
</script>
</html>

后台代码:

package com.moson.backstage.controller;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
/**
 * LoginController
 * @author MoXingJian
 * @email 939697374@qq.com
 * @date 2017年6月20日 下午3:03:50
 * @version 1.0
 */
@WebServlet("/login")
public class LoginController extends HttpServlet{
	
	@Override
	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		doPost(request,response);
	}
	
	@Override
	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		String name = request.getParameter("name");
		String password = request.getParameter("password");
		 response.setCharacterEncoding("UTF-8"); 
		response.setContentType("text/xml;charset=UTF-8");
		PrintWriter out = response.getWriter();
		if(name.equals("MoSon") && password.equals("123456")){
			out.write("{\"result\":true}"); 
		}else{
			out.write("{\"result\":false}"); 
		}
		out.flush();
		out.close();
	}
}
