小編給大家分享一下vue-lazyload圖片延遲加載插件的示例分析,希望大家閱讀完這篇文章之后都有所收獲,下面讓我們一起去探討吧!
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 // 這個是加載圖片數量 })
4、具體配置api可以看下圖
