八、修改调试

main.js里面引入vue element 和router:

import ElementUI from 'element-ui'
import 'element-ui/lib/theme-chalk/index.css';
import VueRouter from 'vue-router'


Vue.use(ElementUI)
Vue.use(VueRouter)

新建登录vue文件：Ulogin.vue

<template>
  <el-form :model="ruleForm2" :rules="rules2" ref="ruleForm2" label-position="left" label-width="0px"
           class="demo-ruleForm login-container">
    <h3 class="title">系统登录</h3>
    <el-form-item prop="account">
      <el-input type="text" v-model="ruleForm2.account" auto-complete="off" placeholder="账号"></el-input>
    </el-form-item>
    <el-form-item prop="checkPass">
      <el-input type="password" v-model="ruleForm2.checkPass" auto-complete="off" placeholder="密码"></el-input>
    </el-form-item>
    <el-form-item style="width:100%;">
      <el-button type="primary" style="width:100%;" @click.native.prevent="handleSubmit2" >登录
      </el-button>
    </el-form-item>
  </el-form>
</template>

<script>
  export default {
    name: "Ulogin.vue",
    data() {
      var checkAccount = (rule, value, callback) => {
        if (!value) {
          return callback(new Error('请输入账号'));
        } else if (value.length < 4 || value.length>12) {
          return callback(new Error('账号名必须在4~12位'));
        } else {
          callback();
        }
      };
      var checkPass = (rule, value, callback) => {
        if (value === '') {
          return callback(new Error('请输入密码'));
        } else if (value.length < 2) {
          return callback(new Error('密码不能小于两位'));
        } else {
          return callback();
        }
      };
      return {
        ruleForm2: {
          account: '',
          checkPass: ''
        },
        rules2: {
          account: [
            {validator: checkAccount, trigger: 'blur'},
          ],
          checkPass: [
            {validator: checkPass, trigger: 'blur'},
          ]
        }
      };
    },
    methods: {
      handleSubmit2(ruleForm2) {
        this.$refs.ruleForm2.validate((valid) => {
          if (valid) {
            alert('提交！')
          } else {
            alert('登陆失败！');
            console.log('error submit!!');
            return false;
          }
        });
      }
    }
  }
</script>
<style lang="scss" scoped>
  .login-container {
    /*box-shadow: 0 0px 8px 0 rgba(0, 0, 0, 0.06), 0 1px 0px 0 rgba(0, 0, 0, 0.02);*/
    -webkit-border-radius: 5px;
    border-radius: 5px;
    -moz-border-radius: 5px;
    background-clip: padding-box;
    margin: 180px auto;
    width: 350px;
    padding: 35px 35px 15px 35px;
    background: #fff;
    border: 1px solid #eaeaea;
    box-shadow: 0 0 25px #cac6c6;
    .title {

      text-align: center;
      color: #505458;
    }
    .remember {
      margin: 0px 0px 35px 0px;
    }
  }
</style>

router内index.js文件配置路由：

import Ulogin from '../components/Ulogin'

Vue.use(Router)

export default new Router({
  routes: [
    // {
    //   path: '/',
    //   name: 'HelloWorld',
    //   component: HelloWorld
    // },
    {
      path:'/',
      name:'',
      component:Ulogin
    }
  ]
})

App.vue

<template>
  <div id="app">
    <router-view/>
  </div>
</template>

<script>
  export default {
    name: 'App'
  }
</script>

<style>
  #app {
    font-family: 'Avenir', Helvetica, Arial, sans-serif;
    -webkit-font-smoothing: antialiased;
    -moz-osx-font-smoothing: grayscale;
    text-align: center;
    color: #2c3e50;

    margin-top: 60px;
  }
</style>

目录结构：

运行：npm run dev
