vue瀑布流下滑加载更多组件waterfall2使用

1.首先安装依赖

npm install --save vue-waterfall2

2.在main.js中引入

import waterfall from 'vue-waterfall2'
Vue.use(waterfall)

3.在需要使用的组件中引入(这里有一个坑，就是如果是嵌套在父组件的div中，那么waterfall必须定义高度，我是通过用document.documentElement.clientHeight时时获取body高度为waterfall动态添加高度)

<template>
  <div class="main">
    <el-row>
      <el-input v-model="content" :clearable="true" placeholder="请输入要搜索的模板" prefix-icon="el-icon-search" @change="change" />
    </el-row>
    <waterfall :height="wfHeight" :col="col" :data="data" @loadmore="loadmore" @scroll="scroll">
      <template class="templateStyle">
        <div class="elimg" style="width:90%;" v-for="item in data" :key="item.id">
          <div @click="templateDetail(item.id)">
            <el-image :src="item.imgUrl" alt="" />
          </div>
        </div>
      </template>
    </waterfall>
  </div>
</template>
