在$ rootScope中存储数据 [英] Storing data in $rootScope

问题描述

建议将数据存储在$ rootScope中. 我有一个cordova应用，该应用使用每100毫秒发送一次的传感器数据.为了在多个控制器中使用该数据，我使用了$ rootScope.sensorData变量，该变量每100毫秒刷新一次.这样使用可以吗?有更好的方法吗?

Is it advisable to store data in $rootScope. I have a cordova app which uses sensor data which is coming every 100ms. For me to use that data in multiple controller I am using $rootScope.sensorData variable which is being refreshed every 100ms. Is it alright to use it this way? Is there a better way to do it?

谢谢

推荐答案

您可以将其存储在工厂中.在AngularJS中，工厂是单例的，因此仅创建实例.

You can store it in factory. In AngularJS factory is singleton, so only instance is created.

myApp.factory('SensorSrv', function SensorSrv() {
  var sensorData;
  return {
    setData: setData,
    getData: getData
  };

  function setData(data) {
    sensorData = data;
  }

  function getData() {
    return sensorData;
  }
});

如果您要保留数据，也可以使用本地存储.

You can also user local-storage if you want to persist the data.
