vue-lazyload图片延迟加载插件

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: [                '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>
