问云函数生成聚合之后createSelectorQuery().selectAll失效？

生成这个聚合之后，能获取聚合内每层数组内index，但是

wx.createSelectorQuery().selectAll失效所以导致左右联动的右联动失效，本来想通过这个生成一个数组启动左右联动，还一直报错

js const db=wx.cloud.database(); const $ = db.command.aggregate; var that = ''; var query; var arr = []; Page({ data: { list:[], idx: 0, scrollTop: 0, toView:'positon0' }, onLoad: function (options) { that = this; query = wx.createSelectorQuery(); wx.createSelectorQuery().selectAll('.position').boundingClientRect(function (rects) { that.setData({ positions:rects }) }).exec(); wx.cloud.callFunction({ // 要调用的云函数名称 name: 'All', // 传递给云函数的event参数 data: { } }).then(res => { console.log(res.result.list); this.setData({ list: res.result.list }) // output: res.result === 3 }).catch(err => {console.log(err) // handle error }) }, switchClassfun(e){ var e = e.currentTarget.dataset.index; this.setData({ idx: e, toView: 'position' + e }) }, bindscrollfunc(e){ var arr = []; console.log(e) for(var item of this.data.positions){ if (item.top <= e.detail.scrollTop + 2){ arr.push(item) } } this.setData({ idx:arr[arr.length-1].dataset.index }) }, })
