我把这个封装成一个组件的形式，方便大家使用，以下为swiper组件代码

<template>
	<view class="swiper" ref="swiper">
		<view class="strip" ref="strip">
			<view class="strip-item" v-for="(item,index) in list" :key="index" @touchstart="touchStart($event,index)"
				@touchmove="touchMove($event,index)" @touchend="touchEnd($event,index)">
				<image class="cover" :src="item.image" mode=""></image>
				<image class="button" src="https://file.yuanyinfu.com/front-end-lib/play.png" mode="" @tap="handGo(item.url)"></image>
			</view>
		</view>
		<view class="page">
			<view v-for="(item,index) in list" :key="index" :class="['page-item',activeIndex===index?'active':'']">
			</view>
		</view>
	</view>
</template>

<script>
