分享一个精简的vue.js 图片lazyload插件

这个插件未压缩版本只有7.62kb,很精简,支持img标签和background-img资源的lazyload。支持vue.js 1.0 和vue.js 2.0

安转

$ npm install vue-lazyload --save

使用方法

//main.js

import Vue from 'vue'
// import VueLazyload
import VueLazyload from 'vue-lazyload'

//use custom directive
Vue.use(VueLazyload)

// use options
Vue.use(VueLazyload, {
  preLoad: 1.3,
  error: 'dist/error.png',
  loading: 'dist/loading.gif',
  attempt: 1
})

new Vue({
  el: 'body',
})
<!--your.vue-->
<script>
export default {
  data () {
    return {
      list: [
        'your_images_url', 
        'your_images_url', 
        // you can customer any image's placeholder while loading or load failed
        {
          src: 'your_images_url.png',
          error: 'another-error.png',
          loading: 'another-loading-spin.svg'
        }
      ]
    }
  }
}
</script>

<template>
  <div class="img-list">
    <ul id="container">
      <li v-for="img in list">
        <img v-lazy="img">
      </li>
    </ul>
  </div>
</template>

这里可以定制所有加载中和加载失败加载成功的样式,

<style>
  img[lazy=loading] {
    /*your style here*/
  }
  img[lazy=error] {
    /*your style here*/
  },
  img[lazy=loaded] {
    /*your style here*/
  }
  /*
  or background-image
  */
  .yourclass[lazy=loading] {
    /*your style here*/
  }
  .yourclass[lazy=error] {
    /*your style here*/
  },
  .yourclass[lazy=loaded] {
    /*your style here*/
  }
</style>
