说明：

实现图中所示的的左侧标签栏可上下滑动，右侧区域为对应左侧标签展开的图片文字详情说明，也具备上下滑动的功能

scroll-view

可滚动试图区域
本文着重使用”scroll-y“即纵向滑动

<template>
	<view class="classify">
		<!-- 左侧标签区域 -->
		<scroll-view class="left" scroll-y>
			<!-- 定义一个acitves为0，与index的索引绑定,若相等赋予类名，不相等为空 -->
			<view :class="actives === index ? 'active' : ''"  
			v-for="(item, index) in cates" 
			:key="item.id"
			@click="leftClickHandle(index, item.id)"
			>
				{{ item.title }}
			</view>
		</scroll-view>
		<!-- 右侧图片区域 -->
		<scroll-view class="right" scroll-y>
			<view class="item" v-for="item in secondData" :key="item.id">
				<image @click="previewImg(item.img_url)" :src="item.img_url"></image>
				<text>{{item.title}}</text>
			</view>
			<text class="none" v-if="secondData.length === 0">暂无数据,请浏览其他页面!</text>
		</scroll-view>
		
	</view>
</template>

				})
				this.cates = res.data.message
				this.leftClickHandle(0, this.cates[0].id)
