lazyload图片延迟加载插件的实例讲解

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> <li v-for="img in list"> <img v-lazy="img"> </li> </ul> </div> </template>

JS

<script> export default { data () { return { list: [ 'http://st2.depositphotos.com/thumbs/2627021/image/9638/96385166/api_thumb_450.jpg!thumb', 'http://st2.depositphotos.com/thumbs/2627021/image/9638/96385166/api_thumb_450.jpg!thumb', 'http://st2.depositphotos.com/thumbs/2627021/image/9638/96385166/api_thumb_450.jpg!thumb', 'http://st2.depositphotos.com/thumbs/2627021/image/9638/96385166/api_thumb_450.jpg!thumb', 'http://st2.depositphotos.com/thumbs/2627021/image/9638/96385166/api_thumb_450.jpg!thumb', 'http://st2.depositphotos.com/thumbs/2627021/image/9638/96385166/api_thumb_450.jpg!thumb', 'http://st2.depositphotos.com/thumbs/2627021/image/9638/96385166/api_thumb_450.jpg!thumb', ] } } } </script>

css

<style> //图片加载中... img[lazy=loading] { /*width: 100px;*/ background-position:center center!important; background: url("../../../static/images/loading.gif"); background-size:100px 100px; background-repeat:no-repeat; -webkit-background-size: cover; -moz-background-size: cover; -o-background-size: cover; background-size: cover; } img[lazy=error] { /*width: 100px;*/ background-position:center center!important; background: url("../../../static/images/error.png"); background-size:100px 100px; background-repeat:no-repeat; -webkit-background-size: cover; -moz-background-size: cover; -o-background-size: cover; background-size: cover; } img[lazy=loaded] { /*width: 100px;*/ background-position:center center!important; -webkit-background-size: cover; -moz-background-size: cover; -o-background-size: cover; background-size: cover; background-color: green; } /* or background-image */ .yourclass[lazy=loading] { /*your style here*/ } .yourclass[lazy=error] { /*your style here*/ } .yourclass[lazy=loaded] { /*your style here*/ } </style>
