使用动态组件实现组件切换

定义两个组件

Student.vue

<template>
  <div>
    <el-tag type="danger" style="margin-top: 10px">当前是学生表</el-tag>
    <el-table :data="students" style="width: 60%;margin-left: 20%;margin-top: 20px" border>
      <el-table-column prop="id" label="编号" align="center"></el-table-column>
      <el-table-column prop="name" label="姓名" align="center"></el-table-column>
      <el-table-column prop="sex" label="性别" align="center"></el-table-column>
    </el-table>
  </div>
</template>

<script>
export default {
  name: 'Student',
  data(){
    return{
      students:[
        {
          id:1,
          name:'小米',
          sex:'男'
        },
        {
          id:2,
          name:'小花',
          sex:'女'
        },
        {
          id:3,
          name:'小明',
          sex:'男'
        },
        {
          id:4,
          name:'雪莉',
          sex:'女'
        }
      ]
    }
  }
}
</script>

<style scoped>

</style>

Teacher.vue

<template>
  <div>
    <el-tag type="warning" style="margin-top: 10px">当前是教师表</el-tag>
    <el-table :data="teachers" style="width: 60%;margin-left: 20%;margin-top: 20px" border>
      <el-table-column prop="id" label="编号" align="center"></el-table-column>
      <el-table-column prop="name" label="姓名" align="center"></el-table-column>
      <el-table-column prop="sex" label="性别" align="center"></el-table-column>
    </el-table>
  </div>
</template>

<script>
export default {
  name: 'Teacher',
  data(){
    return{
      teachers:[
        {
          id:1,
          name:'Tom',
          sex:'男'
        },
        {
          id:2,
          name:'Sherry',
          sex:'女'
        },
        {
          id:3,
          name:'Jack',
          sex:'男'
        },
        {
          id:4,
          name:'Mary',
          sex:'女'
        }
      ]
    }
  }
}
</script>

<style scoped>

</style>

在App.vue中引入上面两个组件

App.vue

<template>
  <div style="text-align: center">
    <el-button type="primary" @click="currentCom='Student'">查看学生</el-button>
    <el-button type="primary" @click="currentCom='Teacher'">查看教师</el-button>
    <component :is="currentCom"></component>
  </div>
</template>

<script>
import Student from './components/Student'
import Teacher from './components/Teacher'

export default {
  name: 'App',
  data () {
    return {
      currentCom: ''
    }
  },
  components: {
    Student,
    Teacher
  }
}
</script>

<style scoped>

</style>
