 const query = wx.createSelectorQuery();

    query.select(’#navigationBar’).boundingClientRect(function (rect) {

      debugger;

      thisEls.setData({

        navBarh: rect.height

      })

    }).exec();

    query.select(’.nav’).boundingClientRect(function (rect) {

      debugger;

      thisEls.setData({

        navh: rect.height

      })

    }).exec();

或者

const query = wx.createSelectorQuery();

query.select(’#navigationBar’).boundingClientRect();

query.select(’.nav’).boundingClientRect();

query.exec(function (res) {

console.log(2);

debugger;

res[0].top       // #the-id节点的上边界坐标

res[1].scrollTop // 显示区域的竖直滚动位置

})

开发工具一切正常，真机一点反应都没
