html
这里的关键点就是 :id="'scroll'+index" 以及 :scroll-into-view="intoIndex"
<view class="week-day-item" v-for="(item,index) in weekList" :key="index" @click="queryBus(item)" :id="'scroll'+index" :class="defaultDate.includes(item.date) ? ['active-font'] : (choiceDate.includes(item.date) ? ['active-font'] : '') "> <view class="week-day">{{item.date}}</view> <view class="week-day">{{item.week}}</view> </view>
methods
这里的函数思想就是循环你的日期list，只要选中日期在list有匹配，就把下标给存储到intoIndex，这样 :scroll-into-view 就可以获取到要定位的下标地址了
// scroll定位 operaDate() {this.weekList.forEach((item, index) => { if (item.date.includes(this.choiceDate)) { this.scrollIndex = index } }) this.$nextTick(() => { this.intoIndex = "scroll" + this.scrollIndex }) this.intoIndex = '' },
