vue图片懒加载 —— vue-lazyload的使用

使用方式

1.npm install vue-lazyload --save-dev
2.main.js

import VueLazyLoad from 'vue-lazyload'
Vue.use(VueLazyLoad, {
  preLoad: 1,
  error: require('./assets/img/error.jpg'),
  loading: require('./assets/img/homePage_top.jpg'),
  attempt: 2,
})

3.页面中使用

<template>
    <div id="lazyload">
        <!-- img中使用图片懒加载。 v-lazy代替v-bind:src -->
        <ul class="img">
            <li v-for="(item,index) in imgList"> 
                <img v-lazy="item" alt="" style="width: 768px;"> 
            </li>
        </ul>
 
        <!-- 背景图中使用图片懒加载。 v-lazy:background-image = "" -->
        <ul class="bgImg">
            <li v-for="(item,index) in imgList" v-lazy:background-image="item"></li>
        </ul>
    </div>
</template>
<script>
export default {
    name:'LazyLoadDemo',
    data(){
        return{
            imgList:[
