在vue-cli中实现组件切换

方法一：动态组件

1.在App.vue根组件中引入子组件

import HelloWorld from "./components/HelloWorld.vue";
import student from "./components/student.vue";
import teacher from "./components/teacher.vue";

2.在component属性中添加组件

export default {
  name: "App",
  data() {
    return {
      
    };
  },
  components: {
     HelloWorld,
     student,
     teacher,
  },
};

3.添加动态组件，并设置变量值

<component :is="currentCom"></component>

 data() {
    return {
       currentCom: HelloWorld,
    };
  },

4.给三个按钮绑定点击事件

<button @click="currentCom = 'HelloWorld'">HelloWorld</button>
<button @click="currentCom = 'student'">student</button>
<button @click="currentCom = 'teacher'">teacher</button>

方法二：路由

1.安装路由
cnpm install vue-router

2.定义路由
创建router文件夹，在router内创建index.js文件

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

import student from '../components/student.vue'
import teacher from '../components/teacher.vue'

Vue.use(Router);

export default new Router({
    mode: 'history',
    routes: [{
        path: '/student',
        component: student
    }, {
        path: '/teacher',
        component: teacher
    }]
});

3.挂载/注入main.js

// 默认引入index文件
import router from './router'

 new Vue({
	router
})
