uni-app实现瀑布流效果，支持上拉加载更多（修改后可应用于小程序）

这是一个绝对定位方式的瀑布流实现，直接贴上代码了

<template>
	<view class="content">
		<view hidden>
			<block v-for="(a,b) in imgList">
				<block v-for="(item,index) in a">
					<image @load="imageLoad" :data-src="item.src" :src="item.src" mode="widthFix"></image>
				</block>
			</block>
		</view>
		<view>
			<block v-for="(item,index) in imgList1">
				<image :src="item.src" mode="widthFix" :style="`left: ${item.left}upx;top: ${item.top}upx;`"></image>
			</block>
		</view>
	</view>
</template>

<script>
	var colCount //定义列数
	var colHeightArry = [] //定义列高度数组
	var imgWidth = 375 //单张图片的宽度，可经过调整宽度显示不一样列数

	colCount = parseInt(750 / imgWidth) //计算出列数，这里是两列

	for (var i = 0; i < colCount; i++) {
		colHeightArry[i] = 0
	}

	export default {
		data() {
			return {
				title: 'Hello',
				imgList: [
					[{
