一、方法1：使用Vant組件庫的tab組件

二、 方法2：手動創(chuàng)建tab切換效果

1.在components文件夾下創(chuàng)建切換的.vue頁面、引入使用

import one from "./components/one";import two from "./components/two";import three from "./components/three";import four from "./components/four";components: {    one,    two,    three,    four,},

2.布局：上面放tab點擊的標(biāo)簽，下面放組件呈現(xiàn)對應(yīng)內(nèi)容

// 然后使用v-for循環(huán)出來呈現(xiàn)<template>   <div id="app">      <div>      <!-- 放置tab點擊標(biāo)簽 --> <div :class="{ highLight: whichIndex == index }" v-for="(item, index) in cardArr" :key="index" @click="whichIndex = index">    {{ item.componentName }}</div>      </div>      <div><!-- 放置動態(tài)組件... -->       <!-- keep-alive緩存組件，這樣的話，組件就不會被銷毀，DOM就不會被重新渲染，       瀏覽器也就不會回流和重繪，就可以優(yōu)化性能。不使用的話頁面加載就會慢一點 -->       <keep-alive> <component :is="componentId"></component>       </keep-alive>      </div>   </div></template>

3.寫好上面的tab點擊標(biāo)簽，定義數(shù)據(jù)修改樣式

// 首先我們在data中定義數(shù)組cardArr存放點擊tab的數(shù)據(jù)data() {   return {      whichIndex: 0,      cardArr: [{  componentName: "動態(tài)組件一",  componentId: "one",},{  componentName: "動態(tài)組件二",  componentId: "two",},{  componentName: "動態(tài)組件三",  componentId: "three",},{  componentName: "動態(tài)組件四",  componentId: "four",},      ],    };},

// 又因為需要有高亮狀態(tài)樣式：默認(rèn)索引0高亮.highLight {  box-shadow: 0 15px 30px rgba(0, 0, 0, 0.2);  transform: translate3d(0, -1px, 0);}

三、完整代碼

<template>  <div id="app">    <div>      <div       :class="{ highLight: whichIndex == index }"v-for="(item, index) in cardArr":key="index"@click="  whichIndex = index;  componentId = item.componentId;"      >{{ item.componentName }}      </div>    </div>    <div>      <keep-alive><component :is="componentId"></component>      </keep-alive>    </div>  </div></template><script>import one from "./components/one";import two from "./components/two";import three from "./components/three";import four from "./components/four";export default {  components: {    one,    two,    three,    four,  },  data() {    return {      whichIndex: 0,      componentId: "one",      cardArr: [{  componentName: "動態(tài)組件一",  componentId: "one",},{  componentName: "動態(tài)組件二",  componentId: "two",},{  componentName: "動態(tài)組件三",  componentId: "three",},{  componentName: "動態(tài)組件四",  componentId: "four",},      ],    };  },};</script><style lang="less" scoped>#app {  width: 100%;  height: 100vh;  box-sizing: border-box;  padding: 50px;  .top {    width: 100%;    height: 80px;    display: flex;    justify-content: space-around;    .crad {      width: 20%;      height: 80px;      line-height: 80px;      text-align: center;      background-color: #fff;      border: 1px solid #e9e9e9;    }    .highLight {      box-shadow: 0 15px 30px rgba(0, 0, 0, 0.2);      transform: translate3d(0, -1px, 0);    }  }  .bottom {    margin-top: 20px;    width: 100%;    height: calc(100% - 100px);    border: 3px solid pink;    display: flex;    justify-content: center;    align-items: center;  }}</style>
