首先 ,在命令行輸入npm install vue-lazyload&&cnpm install vue-lazyload
然后,在main.js里引入這個模塊。
import 'VueLazyload' from 'vue-lazyload'
Vue.use(VueLazyload,{
preload:1.3,//預(yù)加載的寬高
loading:"img的加載中的顯示的圖片的路徑",
error:"img加載失敗時現(xiàn)實的圖片的路徑",
attempt:3,//嘗試加載的次數(shù)
listenEvents:['scroll','wheel','mousewheel','resize','animationend','transitionend','touchmove'], //你想讓vue監(jiān)聽的事件
})
然后在app.vue的template里寫一個
<img v-lazy="img.src"/>
然后在app.vue的script里寫
data(){
return {
img:{
src:"圖片的真是路徑"
}
}
}
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'),
//解釋一下為什么是require('.....url'):因為vue自帶webpack打包工具劫扒，如果是圖片路徑就會把他當(dāng)成模塊解析州藕，所以直接引入就好了黔牵。
//記得把里面的路徑換成自己的哦
listenEvents:['mousewheel'],
})
//載入vue-router
//import Vue from 'vue'
/* eslint-disable no-new */
new Vue({
el: '#app',
router,
template: '<App/>',
components: { App }
})
//app.vue
