小程序自定义标题和胶囊横对齐

app.js

App({
  onLaunch: function () {
    let _that=this;
    // 获取手机系统信息
    wx.getSystemInfo({
      success: res => {
        //导航高度
        // this.globalData.navHeight = res.statusBarHeight + 44;
        _that.globalData.statusBarHeight=res.statusBarHeight;
      }, fail(err) {
        console.log(err);
      }
    });
  }
      });
    })
  },
  globalData: {
    statusBarHeight: 0,
    toBar: 44
  }
})

文件夹下的文件

    this.setData({
      statusBarHeight: app.globalData.statusBarHeight,
      toBarHeight: app.globalData.toBar
