Vue實現簡單視圖模板（登錄，后台）

1.登錄

<template>
  <div>
    <el-form ref="loginForm" :model="form" :rules="rules" label-width="80px" class="login-box">
      <h3 class="login-title">歡迎登錄</h3>
      <el-form-item label="賬號" prop="username">
        <el-input type="text" placeholder="請輸入賬號" v-model="form.username"/>
      </el-form-item>
      <el-form-item label="密碼" prop="password">
        <el-input type="password" placeholder="請輸入密碼" v-model="form.password"/>
      </el-form-item>
      <el-form-item>
        <el-button type="primary" v-on:click="onSubmit('loginForm')">登錄</el-button>
      </el-form-item>
    </el-form>

    <el-dialog
      title="溫馨提示"
      :visible.sync="dialogVisible"
      width="30%"
      :before-close="handleClose">
      <span>請輸入賬號和密碼</span>
      <span slot="footer" class="dialog-footer">
        <el-button type="primary" @click="dialogVisible = false">確 定</el-button>
      </span>
    </el-dialog>
  </div>
</template>

<script>
export  default {
  name:"Login",
  data(){
    return {
      form:{
        username: '',
        password: ''
      },
      //表單驗證，需要再el-form-item 元素中增加prop屬性
      rules:{
        username:[
            {required:true,message:'賬號不能為空',trigger:'blur'}
          ],
    password:[
    {required: true,message: '密碼不能為空',trigger:'blur'}
          ]
  },
    //對話框顯示和隱藏
    dialogVisible:false
  }
  },
  methods:{
    onSubmit(formName) {
      //為表單綁定驗證功能
      this.$refs[formName].validate((valid) =>{
        if (valid){
          //使用 vue-router路由到指定頁面，該方式稱之為編程式導航
          this.$router.push("/main");
        } else {
          this.dialogVisible = true;
          return false;
        }
      });
    }
  }
}
</script>

<style lang="scss" scoped>
.login-box{
  border: 1px solid #DCDFE6;
  width: 350px;
  margin:180px auto;
  padding:35px 35px 15px 35px;
  border-radius: 5px;
  -webkit-border-radius: 5px;
  -moz-border-radius: 5px;
  box-shadow:0 0 25px #909399;
}

.login-title{
  text-align:center;
  margin:0 auto 40px auto;
  color:#303133;
}
</style>

 

2.url路徑錯誤

<template>
  <div>
    <h1>404,你的頁面走丟了！</h1>
  </div>
</template>

<script>
export default {
  name: "NotFound"
}
</script>

<style scoped>

</style>

 

 

3.主頁

<template>
  <div>
    <el-container>
      <el-aside width="200px">
        <el-menu :default-openeds="['1']">
          <el-submenu index="1">
            <template slot="title"><i class="el-icon-caret-right"></i>用戶管理</template>
            <el-menu-item-group>
              <el-menu-item index="1-1">
                <!--name,地址，params：傳遞參數，需要對象：v-bind/:-->
               <router-link :to="{name:'UserP', params:{id:1}}">個人信息</router-link>
              </el-menu-item>
              <el-menu-item index="1-2">
                <router-link to="/user/list">用戶列表</router-link>
              </el-menu-item>
              <el-menu-item index="1-3">
                <router-link to="/home">回到主頁</router-link>
              </el-menu-item>
            </el-menu-item-group>
          </el-submenu>
          <el-submenu index="2">
           <template slot="title"><i class="el-icon-caret-right"></i>內容管理</template>
            <e1-menu-item-group>
             <el-menu-item index="2-1">分類管理</el-menu-item>
             <el-menu-item index="2-2">內容列表</el-menu-item>
            </e1-menu-item-group>
          </el-submenu>
          <el-submenu index="3">
            <template slot="title"><i class="el-icon-caret-right"></i>系統管理</template>
            <e1-menu-item-group>
              <el-menu-item index="3-1">系統設置</el-menu-item>
            </e1-menu-item-group>
          </el-submenu>
        </el-menu>
      </el-aside>
      <el-container>
        <el-header style="text-align: right; font-size: 12px">
         <el-dropdown>
            <i class="el-icon-setting" style="margin-right:15px"></i>
            <el-dropdown-menu slot="dropdown">
             <el-dropdown-item>個人信息</el-dropdown-item>
             <el-dropdown-item>退出登錄</el-dropdown-item>
           </el-dropdown-menu>
          </el-dropdown>

        </el-header>

        <el-main>
          <router-view/>
        </el-main>
      </el-container>
    </el-container>
  </div>
</template>

<script>
export default {
  name: "main"
}
</script>

<style scoped lang="scss">
.el-header {
  background-color: #4abaf8;
  color: #333;
  line-height: 60px;
}

.el-aside {
  color: #333;
}
</style>

 

4.主頁子模塊，用戶列表

<template>
  <h1>用戶列表</h1>
</template>

<script>
export default {
  name: "UserList"
}
</script>

<style scoped>

</style>

 

5.主頁子模塊，個人信息

<template>
  <div>
    <!--所有元素必須不能放在根節點下-->
    <h1>個人信息</h1>
<!--    {{$route.params.id}}-->
    {{id}}
    <div v-model="form">
      <p v-model="form.name">{{form.name}}</p>
    </div>
  </div>

</template>

<script>
export default {
  props:['id'],
  name: "UserProfile",
  beforeRouteEnter:(to,from,next)=>{
    console.log("進入路由之前");//在這里加載數據（axios）
    next(vm=>{
      vm.getData();//進入路由之前執行getData
    });
  },
  beforeRouteLeave:(to,from,next)=>{
    console.log("進入路由之后");
    next();
  },
  data(){
    return{
      form:{
        name:'',
        url:''
      }
    }
  },
  methods:{
    getData:function (){
      this.axios({
        method:'get',
        url:'http://localhost:8080/static/mock/data.json'
      }).then(function (response){
          console.log(response);


      })
    }
  }
}
</script>

<style scoped>

</style>

 

 

 

6.路由

import Vue from 'vue'
import Router from 'vue-router'

import Main from '../views/Main'
import Login from '../views/Login'

import UserList from '../views/user/List'
import Profile from '../views/user/Profile'

//404
import NotFound from "../views/NotFound";

Vue.use(Router);

export default new Router({
  mode:'history',
  routes:[
    {
      path:'/main',
      component:Main,//嵌套路由
      props:true,
      children:[
        {path: '/user/Profile/:id',name:'UserP',component: Profile,props:true},
        {path: '/user/List',component: UserList}
        //path,寫的是服務端的網址，component中的才是真正要引入界面的地址
      ]
    },{
      path:'/login',
      component: Login
    },{//重定向
      path:'/home',
      redirect:'/main'//重定向到Main的請求上，走/main的path
    },{
      //404
      path: '*',
      component:NotFound
    }
  ]
});
