Angular页面间切换及传值的4种方法

state('producers', {
 url: '/producers',
 templateUrl: 'views/producers.html',
 controller: 'ProducersCtrl'
})
.state('producer', {
 url: '/producer/:producerId',
 templateUrl: 'views/producer.html',
 controller: 'ProducerCtrl'
})

.controller('ProducersCtrl', function ($scope, $state) {
 $scope.toProducer = function (producerId) {
  $state.go('producer', {producerId: producerId});
 };
});

.controller('ProducerCtrl', function ($scope, $state, $stateParams) {
 var producerId = $stateParams.producerId;
});

.factory('myFactory', function () {
 //定义factory返回对象
 var myServices = {};
 //定义参数对象
 var myObject = {};
  
 /**
  * 定义传递数据的set函数
  * @param {type} xxx
  * @returns {*}
  * @private
  */
 var _set = function (data) {
  myObject = data; 
 };
 
 /**
  * 定义获取数据的get函数
  * @param {type} xxx
  * @returns {*}
  * @private
  */
 var _get = function () {
  return myObject;
 };
 
 // Public APIs
 myServices.set = _set;
 myServices.get = _get;
  
 // 在controller中通过调set()和get()方法可实现提交或获取参数的功能
 return myServices;
  
});

.factory('addressFactory', ['$rootScope', function ($rootScope) {
 // 定义所要返回的地址对象
 var address = {};
  
 // 定义components数组，数组包括街道，城市，国家等
 address.components = [];
 
 // 定义更新地址函数，通过$rootScope.$broadcast()设置全局事件'AddressUpdated'
 // 所有子作用域都能监听到该事件
 address.updateAddress = function (value) {
 this.components = value.slice();
 $rootScope.$broadcast('AddressUpdated');
 };
  
 // 返回地址对象
 return address;
}]);

// 动态获取地址，接口方法省略
var component = {
 addressLongName: xxxx,
 addressShortName: xxxx,
 cityLongName: xxxx,
 cityShortName: xxxx  
};
 
// 定义地址数组
$scope.components = [];
 
$scope.$watch('components', function () {
 // 将component对象推入$scope.components数组
 components.push(component);
 // 更新addressFactory中的components
 addressFactory.updateAddress(components);
});

// 通过addressFactory中定义的全局事件'AddressUpdated'监听地址变化
$scope.$on('AddressUpdated', function () {
 // 监听地址变化并获取相应数据
 var street = address.components[0].addressLongName;
 var city = address.components[0].cityLongName;
 
 // 通过获取的地址数据可以做相关操作，譬如获取该地址周边的商铺，下面代码为本人虚构
 shopFactory.getShops(street, city).then(function (data) {
  if(data.status === 200){
   $scope.shops = data.shops;
  }else{
   $log.error('对不起，获取该位置周边商铺数据出错: ', data);
  }
 });
});

// 定义并初始化localStorage中的counter属性
$scope.$storage = $localStorage.$default({
 counter: 0
});
 
// 假设某个factory（此例暂且命名为counterFactory）中的updateCounter()方法
// 可以用于更新参数counter
counterFactory.updateCounter().then(function (data) {
 // 将新的counter值上传到localStorage中
 $scope.$storage.counter = data.counter;
});

$scope.counter = $localStorage.counter;
$scope.$watch('counter', function(newVal, oldVal) {
 // 监听变化，并获取参数的最新值
 $log.log('newVal: ', newVal);
});
