vue-lazyload的使用 图片懒加载

1. 安装插件:

npm install vue-lazyload --save-dev

2. main.js引入插件:

import VueLazyLoad from 'vue-lazyload'
Vue.use(VueLazyLoad,{
    error:'./static/error.png',
    loading:'./static/loading.png'
})

3. vue文件中将需要懒加载的图片绑定 v-bind:src 修改为 v-lazy 

<img class="item-pic" v-lazy="newItem.picUrl"/>

 三.功能扩展:

图片懒加载的简单效果已经实现了,然后就可以按这开发文档的api进行扩展了:

keydescriptiondefaultoptions
preLoad proportion of pre-loading height(预加载高度比例) 1.3 Number
error src of the image upon load fail(图片路径错误时加载图片) 'data-src' String
loading src of the image while loading(预加载图片) 'data-src' String
attempt attempts count(尝试加载图片数量) 3 Number
listenEvents

events that you want vue listen for

(想要监听的vue事件)

默认['scroll']可以省略,

当插件跟页面中的动画或过渡等事件有冲突是,

可以尝试其他选项

['scroll'(默认),

'wheel',

'mousewheel',

'resize',

'animationend',

'transitionend',

'touchmove']

Desired Listen Events
adapter

dynamically modify the attribute of element

(动态修改元素属性)

{ } Element Adapter
filter the image's listener filter(动态修改图片地址路径) { } Image listener filter
lazyComponent lazyload component false Lazy Component
dispatchEvent trigger the dom event false Boolean
throttleWait throttle wait 200 Number
observer use IntersectionObserver false Boolean
observerOptions IntersectionObserver options { rootMargin: '0px', threshold: 0.1 } IntersectionObserver
