<p id="app">
  <span v-view-lazy @model="handleModel"></span>
</p>
<script src="https://cdn.jsdelivr.net/npm/vue@2.5.16/dist/vue.js"></script>
<script src="./dist/vue-view-lazy.min.js"></script>
<script>
  Vue.use(vViewLazy.default,{});
  new Vue({
    el:'#app',
    data:{
      msg:'数据'
    },
    methods:{
      handleModel(){
        console.log('出现了');
      },
    },
  })
</script>

$ npm install --save-dev vue-view-lazy

import vView from 'vue-view-lazy'
Vue.use(vView,{
  error:'../../static/images/loading.png',
  loading:'../../static/images/loading.gif',
});

<template>
  <ul id=&#39;img&#39;>
    <li class="in" v-for="(item,i) in imgs" :key="i">
      <img src="#" alt="图片" v-view-lazy="item.src">
    </li>
  </ul>
</template>
<script>
  export default {
    data () {
      return {
        msg: 'Welcome to Your Vue.js App',
        imgs:[
          {src:'../../static/images/img1.jpg'},
          {src:'../../static/images/img2.png'},
          {src:'../../static/images/img2.jpg'},

          {src:'../../static/images/img4.jpg'},
          {src:'../../static/images/img5.jpeg'}, 
        ]
      }
    },
    mounted(){
    },
  }
</script>
<style scoped>
  ...
</style>

<template>
  <p>
    <!--@model自定义事件是在该dom在第一次出现在视口内时触发的方法-->
    <!--v-view-lazy=&#39;method&#39; 或 v-view-lazy=&#39;(e)=>method(e,...arg)'-->
    <p class="cnt" v-for="(v,i) in msg" :key="i" v-view-lazy @model="(e)=>getAjaxContent(e,v.msg)">
      loading...
    </p>

      return{
        msg:[]
      }
    },
    mounted(){
      fetch('http://localhost:3000/test').then(res=>res.json()).then(res=>{
        this.msg = res;
      })
    },
    methods:{
      getAjaxContent(event,msg){
        event.innerText = msg
