下面小編就為大家分享一篇vue-lazyload圖片延遲加載插件的實例講解，具有很好的參考價值，希望對大家有所幫助。一起跟隨小編過來看看吧

1、首先在npm上下載vue-lazyload的引用包

npm install vue-lazyload --save-dev

2、然后我們在main.js里面import這個包，當然，單單這一個包是不夠的，還得其他的文件

import Vue from 'vue';
import App from './App.vue'
import router from './router';
import VueLazyload from "vue-lazyload"

3、然后我們配置vue-lazyload

Vue.use(VueLazyload, {
error: 'static/error.png',//這個是請求失敗后顯示的圖片
loading: 'static/loading.gif',//這個是加載的loading過渡效果
try: 2 // 這個是加載圖片數(shù)量
})

4、具體配置api可以看下圖

html

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

<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>
//圖片加載中...
img[lazy=loading] {
 /*width: 100px;*/
 background-position:center center!important;
