首先 ,在命令行输入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template里写一个
<img v-lazy="img.src"/>
然后在app.vue的script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
