最近在学习小程序，正好发现一个问题，微信小程序多列表渲染数据开关怎么互不影响，记录一下，分享给大家

<!--pages/list/list.wxml--><wxs src="../../utils/filter.wxs" module="filter" /><view class="list"> <view wx:for="{{list}}" wx:key="{{index}}" class="ban" data-main='{{index}}'> <view class="time">{{filter.replaceStar(index)}}</view> <view wx:for="{{item}}" wx:key="*this" class="cen ovf" data-id='{{item.id}}' data-index='{{index}}' > <navigator url="../details/details?id={{item.id}}" open-type="navigate" class="ovf item_1"> <view> <view class="name">{{item.ymname}}</view> <view class="msg">{{item.ymms}}</view> </view> </navigator> <view class="check ovf"> <view id="jl" bindtap='cancle' wx:if="{{item.seleced==1}}" data-fid='{{item.fid}}' data-id='{{item.id}}' data-index='{{index}}'>已记录</view> <picker mode="date" data-id='{{item.id}}' data-index='{{index}}' data-fid='{{item.fid}}' bindchange="bindDateChange" bindcancel="bindcancel" class="item_2" name="picker" wx:if="{{item.seleced!=1}}"> <view id="jl" bindchange="checkboxChange" value='{{date}}'>记录</view> </picker> <view class="zi" wx:if="{{item.seleced==1}}">{{item.time}}</view> </view> </view> </view></view><view class="fix" bindtap='wait'> <text>查看待\n打疫苗</text></view>// pages/list/list.jsconst app = getApp()var time =''Page({ data: { id:0, list: [], date:'', tr:'', s:'' }, //事件处理函数 // bindcancel:function (e) { // var that = this // console.log(e.target.dataset.id) // that.setData({ // tr: 1, // }) // }, bindDateChange:function (e) { console.log('picker发送选择改变，携带值为', e.detail.value) time = e.detail.value var that = this var arr = that.data.list var index = e.target.dataset.index var index1 = e.target.dataset.fid arr[index1][index].seleced = 1 arr[index1][index].time = e.detail.value that.setData({ id: e.target.dataset.id, date: time, list: arr }) }, cancle:function (e) { var that = this var arr = that.data.list var index = e.target.dataset.index var index1 = e.target.dataset.fid arr[index1][index].seleced = '' that.setData({ id: e.target.dataset.id, list: arr }) }, wait:function () { wx.navigateTo({ url: '../wait/wait' }) }, lis: function () { wx.navigateTo({ url: '../archives/archives' }) }, onLoad: function () { var that = this wx.request({ url: 'https://m.renyiwenzhen.com/xcx_ajax.php?action=yimiaolist', //仅为示例，并非真实的接口地址 method: 'post', header: { 'content-type': 'application/json' // 默认值 }, success(res) { console.log(res.data) that.setData({ list: res.data }) } }) }})

总结：

这里使用了双层循环，需要注意的是使用wx:key='*this'循环本身
使用wx:if="{{item.seleced==1}}"标记点击效果，给数据自定义属性

arr[index1][index].seleced = 1
