       首先，我们先安装ElementUI。运行vue ui，搜索依赖，安装

　　在main.js添加使用两个引用，一个加载。 

import Vue from ‘vue‘
import App from ‘./App.vue‘
import router from ‘./router‘
import ElementUI from ‘element-ui‘
import ‘element-ui/lib/theme-chalk/index.css‘;

Vue.config.productionTip = false

Vue.use(ElementUI);

new Vue({
  router,
  render: h => h(App)
}).$mount(‘#app‘)

 

       我们先来调整一下App.vue中样式

<style lang="scss">
    #app {
        -webkit-font-smoothing: antialiased;
        -moz-osx-font-smoothing: grayscale;
        color: #2c3e50;
    }
</style>

 

       然后是login.vue，目前我们没有后台，用户名和密码暂时写死在前台：admin/123456

 1 <template>
 2     <div class="login-page-container">
 3         <el-form :model="loginForm" :rules="loginRules" ref="loginForm" label-position="left" label-width="0px"
 4                  class="demo-ruleForm login-container">
 5             <h3 class="title">系统登录</h3>
 6             <el-form-item prop="account">
 7                 <el-input type="text" v-model="loginForm.account" auto-complete="off" placeholder="账号"></el-input>
 8             </el-form-item>
 9             <el-form-item prop="password">
10                 <el-input type="password" v-model="loginForm.password" auto-complete="off" placeholder="密码"></el-input>
11             </el-form-item>
12             <el-form-item style="width:100%;">
13                 <el-button type="primary" style="width:100%;" @click="submit" :loading="loading">登录</el-button>

15         </el-form>
