html片段

<template>
    <div class="swiper-container" style='background-color: #020D35;height:100vh;'>
        <div class="swiper-wrapper">
            <div class="swiper-slide" style="height: 100vh;"><Home></Home></div>
            <div class="swiper-slide" style='height:100vh;'><TeachersData></TeachersData></div>
            <div class="swiper-slide" style='height:100vh;'><WisdomEducational></WisdomEducational></div>
            <div class="swiper-slide" style='height:100vh;'><ResearchResults></ResearchResults></div>
        </div>
        
        <!-- 如果需要导航按钮 -->
        <!-- <div class="swiper-button-prev"></div>
        <div class="swiper-button-next"></div> -->
        
        <!-- 如果需要滚动条 -->
        <div class="swiper-scrollbar"></div>
    </div>
</template>

js片段

<script>
import Home from "./home/home"
import TeachersData from "./teachersData/teachersData"
import Swiper from "swiper"
import WisdomEducational from "./wisdomEducational/wisdomEducational"
import ResearchResults from "./researchResults/researchResults"

export default {
    components:{
        Home,
        TeachersData,
        WisdomEducational,
        ResearchResults
    },
    data(){
        return{
			isShow: false
        }
    },
    created(){
        this.$nextTick(function(){  //因为初始化swiper需要获取dom节点，所以要将初始化的代码写入 this.$nexTick 里，或者写在mounted钩子函数里
            var mySwiper = new Swiper ('.swiper-container', {
                loop: false, // 循环模式选项
                speed:1000,
				mousewheel: true,
				direction : 'vertical',
                navigation: {
                    nextEl: '.swiper-button-next',
                    prevEl: '.swiper-button-prev',
                },				
            })  
        })	
    },
    mounted(){
   }
}
</script>

3.使用swiper Anamate

1.animate.js

[注]：因为swiper官网提供的js文件不是export方式导出的，所以我们引入时会报错，我在各大网站上找到里一个更改以后的js文件。
创建一个js文件 我这里命名为 animate.js，将以下代码复制到创建的js文件里

export function swiperAnimateCache() {
  const allBoxes = window.document.documentElement.querySelectorAll('.ani')
  for (var i = 0; i < allBoxes.length; i++) {
    allBoxes[i].attributes['style']
      ? allBoxes[i].setAttribute('swiper-animate-style-cache', allBoxes[i].attributes['style'].value)
      : allBoxes[i].setAttribute('swiper-animate-style-cache', ' ')
    allBoxes[i].style.visibility = 'hidden'
  }
}

export function swiperAnimate(a) {
  clearSwiperAnimate()
  var b = a.slides[a.activeIndex].querySelectorAll('.ani')
  for (var i = 0; i < b.length; i++) {
    b[i].style.visibility = 'visible'
    const effect = b[i].attributes['swiper-animate-effect']
      ? b[i].attributes['swiper-animate-effect'].value
      : ''
    b[i].className = b[i].className + ' ' + effect + ' ' + 'animated'
    const duration = b[i].attributes['swiper-animate-duration']
      ? b[i].attributes['swiper-animate-duration'].value
      : ''
    // duration && style
    const delay = b[i].attributes['swiper-animate-delay']
      ? b[i].attributes['swiper-animate-delay'].value
      : ''
    const style = b[i].attributes['style'].value + 'animation-duration:' + duration + ';-webkit-animation-duration:' + duration + ';' + 'animation-delay:' + delay + ';-webkit-animation-delay:' + delay + ';'
    // delay && (style = style )
    b[i].setAttribute('style', style)
  }
}

export function clearSwiperAnimate() {
  var allBoxes = window.document.documentElement.querySelectorAll('.ani')
  for (var i = 0; i < allBoxes.length; i++) {
    allBoxes[i].attributes['swiper-animate-style-cache'] && allBoxes[i].setAttribute('style', allBoxes[i].attributes['swiper-animate-style-cache'].value)
    allBoxes[i].style.visibility = 'hidden'
    allBoxes[i].className = allBoxes[i].className.replace('animated', ' ')
    const effectValue = allBoxes[i].attributes['swiper-animate-effect'].value
    /* eslint-disable-next-line */
    allBoxes[i].attributes['swiper-animate-effect'] && (effectValue, allBoxes[i].className = allBoxes[i].className.replace(effectValue, ' '))
  }
}

2. animate.css
   css文件在swiper官网上就有，传送门：animate.css
   
   3.在需要使用的页面引入js 和 css文件
   js（在 script标签内部引入）

import * as swiperAni from '../../assets/animate/animate.js' //根据自己的路径进行引入

css（在style标签内部引入）

@import url('../../assets/animate/animate.min.css');

4.开始使用动画
js
在初始化swiper的代方法里加入以下代码 on 的这段代码

  this.$nextTick(function(){
            var mySwiper = new Swiper ('.swiper-container', {
                loop: false, // 循环模式选项
                speed:1000,
				mousewheel: true,
				direction : 'vertical',
                navigation: {
                    nextEl: '.swiper-button-next',
                    prevEl: '.swiper-button-prev',
                },
				on:{
					init: function(){
						swiperAni.swiperAnimateCache(this); //隐藏动画元素 
						swiperAni.swiperAnimate(this); //初始化完成开始动画
					}, 
					slideChangeTransitionStart: function(){ 
						swiperAni.swiperAnimate(this); //每个slide开始切换时也运行当前slide动画
						//this.slides.eq(this.activeIndex).find('.ani').removeClass('ani'); 动画只展现一次，去除ani类名
					} 
				}
            })  
        })

html
给需要展示动画的dom节点上加入以下内容

//

<template>
    <div class="swiper-container" style='background-color: #020D35;height:100vh;'>
        <div class="swiper-wrapper">
            <div class="swiper-slide" style="height: 100vh;">
            	<Home class="ani" swiper-animate-effect="bounceInLeft" swiper-animate-duration="0.5s" swiper-animate-delay="0s"></Home>
            </div>
        </div>
</template>

class=“ani” 是必须要加的
swiper-animate-effect=“bounceInLeft” （动画的样式，这个根据animate.css官网上的演示，自行挑选）
动画演示
swiper-animate-duration=“0.5s” swiper-animate-delay=“0s” （动画持续的时间）

4.最终效果
