    wx.getSystemInfo({
      success: res => {
        let statusBarHeight = res.statusBarHeight,
          navTop = menuButtonObject.top,//胶囊按钮与顶部的距离
          navHeight = statusBarHeight + menuButtonObject.height + (menuButtonObject.top - statusBarHeight) * 2;//导航高度
        this.globalData.navHeight = navHeight;
        this.globalData.navTop = navTop;
        this.globalData.windowHeight = res.windowHeight;
      },
