uniapp在APP端使用swiper进行页面会卡顿，主要是渲染的数据有点多，这里只渲染三个数据就不好那么卡顿了，每次滑动后更新数据

<view><swiper @change="changePoint" circular :disable-touch="disableTouch"><swiper-item v-for="(item, index) in orderSafeMonitorList" :key="index"><view class="title">......</view></swiper-item></swiper>
</view>

export default {data() {return {allOrderSafeMonitorList: [],//所有测点数据orderSafeMonitorList: [],//部分测点数据（只取三组）current: 0, //这是当前所在索引swiperIndex: 0, //这是当前swiper在的索引disableTouch: false, //是否禁止滑动};},onLoad(option) {this.getData()//获取测点列表},methods: {getData() {// 获取测点数据this.allOrderSafeMonitorList = '全部测点数据'this.getList()},getList() {this.orderSafeMonitorList[1] = this.allOrderSafeMonitorList[this.current]this.orderSafeMonitorList[0] = this.current == 0 ? this.allOrderSafeMonitorList[this.allOrderSafeMonitorList.length - 1] : this.allOrderSafeMonitorList[this.current - 1]this.orderSafeMonitorList[2] = this.current == this.allOrderSafeMonitorList.length - 1 ? this.allOrderSafeMonitorList[0] : this.allOrderSafeMonitorList[this.current + 1]this.getDetail()//获取测点数据详情},//获取测点数据详情getDetail() {this.disableTouch = false//接口请求好了之后即可继续滑动this.$forceUpdate();//强制更新页面，这个没写页面可能没办法显示},//滑动页面changePoint(e) {this.disableTouch = true//当滑动后禁止继续滑档导致卡顿，等接口请求结束再滑动下个页面if (e.detail.current > this.swiperIndex) {if (e.detail.current == 2 && this.swiperIndex == 0) {// 向右滑-减少if (this.current == 0) {this.current = this.allOrderSafeMonitorList.length - 1} else {this.current = this.current - 1}} else {// 向左滑-增加if (this.current == this.allOrderSafeMonitorList.length - 1) {this.current = 0} else {this.current = this.current + 1}}} else {if (e.detail.current == 0 && this.swiperIndex == 2) {// 向左滑-增加if (this.current == this.allOrderSafeMonitorList.length - 1) {this.current = 0} else {this.current = this.current + 1}} else {// 向右滑-减少if (this.current == 0) {this.current = this.allOrderSafeMonitorList.length - 1} else {this.current = this.current - 1}}}this.swiperIndex = e.detail.currentthis.getList()}}}
