1.先用vue-cli3创建一个项目

2.安装element模块

全局安装

npm i element-ui -S

3在main.js引入模块

import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';
Vue.use(ElementUI);

4.这里先扩展一个小知识点

在package.json文件中找scripts下serve,在后面加上--open 可以实现运行项目后自动打开浏览器

5.然后我们在views文件夹下新建一个登陆页面login.vue

6.搭建login页面(这里我们简单的用element修饰一下)

<template>
 <div class="firstdemo">
 <el-form ref="form" :model="form" label-width="80px">
 <el-row type="flex" justify="center">
 <el-col :span="5">
  <el-form-item label="用户名">
  <el-input v-model="form.name"></el-input>
  </el-form-item>
 </el-col>
 </el-row>
 <el-row type="flex" justify="center">
 <el-col :span="5">
  <el-form-item label="密码">
  <el-input v-model="form.password"></el-input>
  </el-form-item>
 </el-col>
 </el-row>

 <el-row type="flex" justify="center">
 <el-col :span="5">
  <el-form-item>
  <el-button type="primary" @click="onSubmit">登陆</el-button>
  <el-button>注册</el-button>
  </el-form-item>
 </el-col>
 </el-row>
 </el-form>
 </div>
</template>
<script>
export default {
 name: "fisrtdemo",
 data() {
 return {
 form: {
 name: "",
 password: ""
 }
 };
 },
 methods: {
 onSubmit() {
 if (this.form.name == "admin" && this.form.password == "123456") {
 this.$message({
  message: '登陆成功',
  type: 'success'
 }); 
 this.$router.push({ path: "/Home" });
 }else{
  this.$message.error('登陆失败');
 }
 }
 }
};
</script>
<style lang="stylus" scoped></style>

由于只是简单的展示以下这里我们用一个死数据

这里简单强调一下在逻辑层实现路由切换

<!-- router.push({path:'/foo'}) -->
　　　　　<!-- 声明式导航 应用于视图层 -->
 <router-link to='/foo'>to foo</router-link>
 <router-view></router-view>
 <!-- 编程式导航 应用于逻辑层-->
 <!-- router.push({path:'/foo'}) -->

到这里login页面基本搭建完成

7.在router下的index.js中引入我们刚刚创建的login.vue

并对路径作相应改动

index.js

import Vue from "vue";
import VueRouter from "vue-router";
import Home from "../views/Home.vue";
import login from "../views/login.vue";
Vue.use(VueRouter);

const routes = [
 {
 path: "/",
 name: "login",
 component: login
 },
 {
 path: "/Home",
 name: "home",
 component: Home
 },
 {
 path: "/about",
 name: "about",
 // route level code-splitting
 // this generates a separate chunk (about.[hash].js) for this route
 // which is lazy-loaded when the route is visited.
 component: () =>
 import(/* webpackChunkName: "about" */ "../views/About.vue")
 }
];

const router = new VueRouter({
 mode: "history",
 base: process.env.BASE_URL,
 routes
});

export default router;

8.最后我们对home作一下简单修饰。

博主这里在components中新建了一个组件helloworld并引入了element中的一个简单的布局容器。

然后在home页面引入helloworld对页面进行渲染(当然也可以像上面一样直接在home中引入element布局容器)

9.运行 npm run serve

10.下面展示以下效果
