npm i animate.css --save

import 'animate.css';

/**
 * 
 * @param {*} element 传入的H5元素对象
 * @param {*} animation 动画名称
 * @param {*} prefix 可以不用传，默认参数即可
 * @returns 
 */
export const animateCSS = (element, animation, prefix = 'animate__') => {
  new Promise((resolve, reject) => {
    const animationName = `${prefix}${animation}`
    
    element.classList.add(`${prefix}animated`, animationName)
 
    function handleAnimationEnd(event) {
      event.stopPropagation()
      element.classList.remove(`${prefix}animated`, animationName)
      resolve('Animation ended')
    }
	
    element.addEventListener('animationend', handleAnimationEnd, {once: true})
  })
}

import { animateCSS } from "@/utils/function";
import { onMounted, ref } from "vue";
 
const introTitle = ref();
const introImg = ref();
const header = ref();
console.log('捡来了');
const domAnime = () => {
  animateCSS(introTitle.value, "fadeInLeft");
  introTitle.value.style.display = "block";

  animateCSS(header.value, "fadeInDown");
};
 
onMounted(() => {
  domAnime();
});
