   })
}

  },
  /**

*/
  downloadAndUpdate: function (updateManager) {
var self = this
wx.showLoading();

// 监听小程序有版本更新事件，客户端主动触发
updateManager.onUpdateReady(function(){
   wx.hideLoading();
   // 新版本下载好，调用applyUpdate
   updateManager.applyUpdate()
})

// 监听小程序更新失败事件
updateManager.onUpdateFailed(function(){
   wx.showModal({
      title: '已经有新版了哦',
      content: '请你删除当前小程序，进行升级哦'
   })
})
  }
})

大神们这段代码错误点在哪里一直不成功
