我真服了这个问题啦，An SelectorQuery call is ignor

• 一直报到死的警告，死都获取不到组件

VM54:1 An SelectorQuery call is ignored because no proper page or component is found. Please considering using `SelectorQuery.in` to specify a proper one.

• 放在onLoad里不行，放在onReady里也不行，延迟5秒都还不行，到底行不行啦！

const query = wx.createSelectorQuery().in(this)
    query.select('#old-house-chat').boundingClientRect(function(res){
      res.top // 这个组件内 #the-id 节点的上边界坐标
    }).exec()

<view class=“ec-expontent”>

<ec-canvas id=“sell-house-chat” canvas-id=“old-house-chat” class=“ec-canvas mychart” ec=“{{ sellhouseEc }}”></ec-canvas>

</view>
