Vue wow.js animate.css实现动画效果

1.介绍

Wow.js 是一个轻量级的 JavaScript 库，用于在网页滚动时实现动画效果。基于 CSS3 的动画库 Animate.css，并通过触发 CSS 动画类来创建各种引人注目的过渡和动画效果。

使用 Wow.js，可以很容易地为网页中的元素添加动画效果，比如淡入、滑入、缩放等。当用户滚动到指定位置时，Wow.js会自动触发相应的动画效果，为用户提供更加流畅和有趣的浏览体验。

Wow.js 的优点在于简单易用，只需几行代码即可实现各种动画效果，并且支持自定义动画样式和回调函数。这使得 Wow.js 成为开发人员和设计师们在构建交互式网页时的有力工具，为用户提供更加吸引人的视觉效果。

3.效果展示

（觉得官网动画很有意思，搬运过来了哈哈哈）

vue+wowjs+animate动画

4.npm下载资源

npm install wowjs --save-dev
npm install animate.css --save

5.为了方便后期修改动画animate.css代码，可以将node_modules/wowjs/libs/animate.css复制到assets/css/animate.css里面

5.mian.js引入

// 引入animate.css
import 'animate.css'
// import animated from 'wowjs/css/libs/animate.css';//不需要后期修改动画可以直接使用该代码
import animated from './assets/css/animate.css';
//这里需要将样式用起来，
Vue.use(animated);

6.实现，元素隐藏2秒后显示且加载动画。使用的swing动画效果需要在0%和20%的时候添加opcity属性，先隐藏再显示

<template>
 <div
      class="textClass wow swing"
      data-wow-duration="2s"
      data-wow-delay="2s"
      style="visibility: hidden;animation-delay: 2s; animation-name: swing;"
    >
      <img
        class=""
        src="https://wowjs.uk/img/wow-logo.jpg"
        style="width: 86%;"
      />
    </div>
    <template/>
    <script>
import { WOW } from "wowjs";//在需要动画的页面引入
export default {
  name: "wows",
  components: {},
  data() {
    return {};
  },
  onload() {
    console.log(123);
  },
  mounted() {
    let wow = new WOW({
      boxClass: "wow", //需要执行动画的元素的 class
      animateClass: "animated", //animation.css 动画的 class
      offset: 150, //距离可视区域多少开始执行动画
      mobile: true, //是否在移动设备上执行动画
      live: true //异步加载的内容是否有效
    });
    wow.init();
  }
};
</script>
<style scoped>
.span3 {
  flex: 1;
  display: flex;
  justify-content: center;
}

.textClass {
  /* height: 80vw; */
  /* background-color: lightblue; */
  text-align: center;
  display: flex;
  justify-content: center;
  align-items: center;
  padding-top: 15vw;
}
</style>
