VUE-lazyload的详细过程

npm install vue-lazyload
&&cnpm install vue-lazyload
然后,在main.js里引入这个模块。
import 'VueLazyload' from 'vue-lazyload' Vue.use(VueLazyload,{ preload:1.3,//预加载的宽高 loading:"img的加载中的显示的图片的路径", error:"img加载失败时现实的图片的路径", attempt:3,//尝试加载的次数 listenEvents:[ 'scroll', 'wheel', 'mousewheel', 'resize', 'animationend', 'transitionend', 'touchmove' ], //你想让vue监听的事件 })
然后在app.vue的模板里写一个<img v-lazy="img.src"/>
然后在app.vue的剧本里写
data(){ return { img:{ src:"图片的真是路径" } } }
捋一下思路:
//main.js // The Vue build version to load with the `import` command // (runtime-only or standalone) has been set in webpack.base.conf with an alias. import Vue from 'vue' import App from './App' import $ from 'jquery' import 'assets/bootstrap/css/bootstrap.min.css' import 'assets/bootstrap/js/bootstrap.min' import router from '@/router/index' import VueLazyload from 'vue-lazyload' Vue.use(VueLazyload,{ preload:1.3, loading:require('../static/imgs/ad3.png'), //解释一下为什么是require('.....url'):因为vue自带webpack打包工具,如果是图片路径就会把他当成模块解析,所以直接引入就好了。 //记得把里面的路径换成自己的哦 listenEvents:['mousewheel'], }) //载入vue-router //import Vue from 'vue' /* eslint-disable no-new */ new Vue({ el: '#app', router, template: '<App/>', components: { App } }) //app.vue <template> <div id="app"> <navbar></navbar> <router-view></router-view> <hello></hello> <ul> <li v-for="item in imgUrl"> <img v-lazy="item.src" alt="" width="300" height="150"/> </li> </ul> <img v-lazy='img[0].src'/> </div> </template> <script> import hello from './components/Hello' import Navbar from '@/components/navBar' import route from '@/components/route' export default { name: 'app', components:{ hello, Navbar }, data() { return { imgUrl: [ {src: require('@/assets/imgs/ad1.png')},//记得把里面的路径换成自己的哦 {src: require('@/assets/imgs/ad1.png')},//记得把里面的路径换成自己的哦 ], img:[ {src:require('@/assets/imgs/ad2.png')}//记得把里面的路径换成自己的哦 ] } } } </script> <style> #app { font-family: 'Avenir', Helvetica, Arial, sans-serif; -webkit-font-smoothing: antialiased; -moz-osx-font-smoothing: grayscale; text-align: center; color: #2c3e50; margin-top: 60px; } </style>
