1、首先在npm上下载vue-lazyload的引用包
npm install vue-lazyload --save-dev
2、然后我们在main.js里面import这个包，当然，单单这一个包是不够的，还得其他的文件
import Vue from 'vue'; import App from './App.vue' import router from './router'; import VueLazyload from "vue-lazyload"
3、然后我们配置vue-lazyload
Vue.use(VueLazyload, {
error: 'static/error.png',//这个是请求失败后显示的图片
loading: 'static/loading.gif',//这个是加载的loading过渡效果
try: 2 // 这个是加载图片数量
})
4、具体配置api可以看下图
html
<template>
<div>
<ul id="container">
<li v-for="img in list">
<img v-lazy="img">
</li>
</ul>
</div>
</template>
JS
<script>
export default {
data () {
return {
list: [
