代码如下：

const query = wx.createSelectorQuery()

const selectors = '.share-report-li, #userInfoBorder, #userInfoHeadimgBorder, #userInfoHeadimg, #userInfoText, #evaluationContent, #knowledgeContentBorder, #knowledgeContent, #shareGroup, #shareLoc, #shareSmallprogramCode, #shareWeixin, #shareGrowUp'

query.selectAll(selectors).boundingClientRect()

query.selectViewport().scrollOffset()

query.exec(res => {

console.log('getLiNodes', res)

})

现象：

（1）获取节点信息有时会出现top负值，有时正常
