vue+elementui搭建后台管理界面-登录_基于elementui 的后台管理登录页面

1 node环境安装

从 node官网下载安装包

2 vue-cli

npm install vue-cli -g

3 新建项目

vue init webpack vue-project

可保持默认，一路回车
完成后

cd vue-project  
npm run dev

4 安装并引入 elementui

npm install element-ui --save

编辑 src/main.js , 修改为

import Vue from 'vue'
import App from './App'
import router from './router'
import ElementUI from 'element-ui'
import 'element-ui/lib/theme-chalk/index.css'
Vue.use(ElementUI)
Vue.config.productionTip = false
new Vue({
  el: '#app',
  router,
  render: h => h(App)
})

5 编写登录页面

src 目录下新建目录 views
编写 views/Login.vue

<template>
     <div class="login-container">
        <el-form :model="ruleForm2" :rules="rules2"
         status-icon
         ref="ruleForm2" 
         label-position="left" 
         label-width="0px" 
         class="demo-ruleForm login-page">
            <h3 class="title">系统登录</h3>
            <el-form-item prop="username">
                <el-input type="text" 
                    v-model="ruleForm2.username" 
                    auto-complete="off" 
                    placeholder="用户名"
                ></el-input>
            </el-form-item>
                <el-form-item prop="password">
                    <el-input type="password" 
                        v-model="ruleForm2.password" 
                        auto-complete="off" 
                        placeholder="密码"
                    ></el-input>
                </el-form-item>
            <el-checkbox 
                v-model="checked"
                class="rememberme"
            >记住密码</el-checkbox>
            <el-form-item style="width:100%;">
                <el-button type="primary" style="width:100%;" @click="handleSubmit" :loading="logining">登录</el-button>
            </el-form-item>
        </el-form>
    </div>
</template>
 
<script>
export default {
     data(){
        return {
            logining: false,
            ruleForm2: {
                username: 'admin',
                password: '123456',
            },
            rules2: {
                username: [{required: true, message: '请输入账号', trigger: 'blur'}],
                password: [{required: true, message: '请输入密码', trigger: 'blur'}]
            },
            checked: false
        }
    },
    methods: {
        handleSubmit(event){
            this.$refs.ruleForm2.validate((valid) => {
                if(valid){
                    this.logining = true;
                    if(this.ruleForm2.username === 'admin' && 
                       this.ruleForm2.password === '123456'){
                           this.logining = false;
                           sessionStorage.setItem('user', this.ruleForm2.username);
                           this.$router.push({path: '/home'});
                    }else{
                        this.logining = false;
                        this.$alert('用户名或密码错误!', '提示', {
                            confirmButtonText: 'ok'
                        })
                    }
                }else{
                    console.log('error submit!');
                    return false;
                }
            })
        }
    }
}
</script>
 
<style scoped>
 
.login-container {
    width: 100%;
    height: 100%;
    background: #4373a5;
 
    /* 登录框上下对齐 */
    display: flex;
    align-items: center;
}
.login-page {
    -webkit-border-radius: 5px;
    border-radius: 5px;
    margin:0px auto;
    width: 350px;
    padding: 20px 35px 35px 15px;
    background: #fff;
    border: 1px solid #eaeaea;
    box-shadow: 0 0 25px #cac6c6;
}
label.el-checkbox.rememberme {
    margin: 0px 0px 15px;
    text-align: left;
}
</style>

6 增加路由

访问 login 要跳转到登录页面
修改 router/index.js 为

import Vue from 'vue'
import Router from 'vue-router'
import HelloWorld from '@/components/HelloWorld'
import Login from '@/views/Login'
 
Vue.use(Router)
 
export default new Router({
  routes: [
    {
      path: '/',
      name: 'HelloWorld',
      component: HelloWorld
    },
    {
      path: '/login',
      name: 'Login',
      component: Login
    },
  ]
})

访问 http://127.0.0.1:8080/#/login 出现登录页面:
