请观看以下视频:控制器之间的通信

Html:

<div ng-controller="ControllerZero">
  <input ng-model="message" >
  <button ng-click="handleClick(message);">LOG</button>
</div>

<div ng-controller="ControllerOne">
  <input ng-model="message" >
</div>

<div ng-controller="ControllerTwo">
  <input ng-model="message" >
</div>

javascript:

var myModule = angular.module('myModule', []);
myModule.factory('mySharedService', function($rootScope) {
  var sharedService = {};

  sharedService.message = '';

  sharedService.prepForBroadcast = function(msg) {
    this.message = msg;
    this.broadcastItem();
  };

  sharedService.broadcastItem = function() {
    $rootScope.$broadcast('handleBroadcast');
  };

  return sharedService;
});

function ControllerZero($scope, sharedService) {
  $scope.handleClick = function(msg) {
    sharedService.prepForBroadcast(msg);
  };

  $scope.$on('handleBroadcast', function() {
    $scope.message = sharedService.message;
  });        
}

function ControllerOne($scope, sharedService) {
  $scope.$on('handleBroadcast', function() {
    $scope.message = 'ONE: ' + sharedService.message;
  });        
}

function ControllerTwo($scope, sharedService) {
  $scope.$on('handleBroadcast', function() {
    $scope.message = 'TWO: ' + sharedService.message;
  });
}

ControllerZero.$inject = ['$scope', 'mySharedService'];        

ControllerOne.$inject = ['$scope', 'mySharedService'];

ControllerTwo.$inject = ['$scope', 'mySharedService'];

我不知道这是否超出了标准，但如果你把所有的控制器都放在同一个文件上，那么你可以这样做:

app = angular.module('dashboardBuzzAdmin', ['ngResource', 'ui.bootstrap']);

var indicatorsCtrl;
var perdiosCtrl;
var finesCtrl;

app.controller('IndicatorsCtrl', ['$scope', '$http', function ($scope, $http) {
  indicatorsCtrl = this;
  this.updateCharts = function () {
    finesCtrl.updateChart();
    periodsCtrl.updateChart();
  };
}]);

app.controller('periodsCtrl', ['$scope', '$http', function ($scope, $http) {
  periodsCtrl = this;
  this.updateChart = function() {...}
}]);

app.controller('FinesCtrl', ['$scope', '$http', function ($scope, $http) {
  finesCtrl = this;
  this.updateChart = function() {...}
}]);

正如你所看到的，当调用updateCharts时，indicatorsCtrl正在调用其他两个控制器的updateChart函数。

有一个方法不依赖于服务$broadcast或$emit。它并不适用于所有情况，但如果你有两个相关的控制器可以抽象成指令，那么你可以在指令定义中使用require选项。这是ngModel和ngForm最可能的通信方式。你可以使用它在嵌套的指令控制器之间通信，或者在同一个元素上。

对于父母/孩子的情况，使用方法如下:

<div parent-directive>
  <div inner-directive></div>
</div>

在父指令中，使用要调用的方法，你应该在this(而不是$scope)上定义它们:

controller: function($scope) {
  this.publicMethodOnParentDirective = function() {
    // Do something
  }
}

在子指令定义上，你可以使用require选项，这样父控制器就被传递给了链接函数(这样你就可以从子指令的作用域调用它上的函数)。

require: '^parentDirective',
template: '<span ng-click="onClick()">Click on this to call parent directive</span>',
link: function link(scope, iElement, iAttrs, parentController) {
  scope.onClick = function() {
    parentController.publicMethodOnParentDirective();
  }
}

以上内容可以在http://plnkr.co/edit/poeq460VmQER8Gl9w8Oz?p=preview上看到

兄弟指令的用法类似，但两个指令都在同一个元素上:

<div directive1 directive2>
</div>

用于在directive1上创建一个方法:

controller: function($scope) {
  this.publicMethod = function() {
    // Do something
  }
}

在directive2中，可以使用require选项调用，这将导致siblingController被传递给link函数:

require: 'directive1',
template: '<span ng-click="onClick()">Click on this to call sibling directive1</span>',
link: function link(scope, iElement, iAttrs, siblingController) {
  scope.onClick = function() {
    siblingController.publicMethod();
  }
}

这可以在http://plnkr.co/edit/MUD2snf9zvadfnDXq85w?p=preview上看到。

它的用途是什么?

Parent: Any case where child elements need to "register" themselves with a parent. Much like the relationship between ngModel and ngForm. These can add certain behaviour that can affects models. You might have something purely DOM based as well, where a parent element needs to manage the positions of certain children, say to manage or react to scrolling. Sibling: allowing a directive to have its behaviour modified. ngModel is the classic case, to add parsers / validation to ngModel use on inputs.

在angular 1.5中，这可以通过以下方式实现:

(function() {
  'use strict';

  angular
    .module('app')
    .component('parentComponent',{
      bindings: {},
      templateUrl: '/templates/products/product.html',
      controller: 'ProductCtrl as vm'
    });

  angular
    .module('app')
    .controller('ProductCtrl', ProductCtrl);

  function ProductCtrl() {
    var vm = this;
    vm.openAccordion = false;

    // Capture stuff from each of the product forms
    vm.productForms = [{}];

    vm.addNewForm = function() {
      vm.productForms.push({});
    }
  }

}());

这是父组件。在这里，我创建了一个函数，将另一个对象推入我的productForms数组-注意-这只是我的示例，这个函数可以是任何东西。

现在我们可以创建另一个使用require的组件:

(function() {
  'use strict';

  angular
    .module('app')
    .component('childComponent', {
      bindings: {},
      require: {
        parent: '^parentComponent'
      },
      templateUrl: '/templates/products/product-form.html',
      controller: 'ProductFormCtrl as vm'
    });

  angular
    .module('app')
    .controller('ProductFormCtrl', ProductFormCtrl);

  function ProductFormCtrl() {
    var vm = this;

    // Initialization - make use of the parent controllers function
    vm.$onInit = function() {
      vm.addNewForm = vm.parent.addNewForm;
    };  
  }

}());

在这里，子组件创建了对父组件函数addNewForm的引用，然后可以将其绑定到HTML并像其他函数一样调用。

另外两个提琴:(非服务方法)

1)对于父-子控制器-使用父控制器的$scope来发射/广播事件。 http://jsfiddle.net/laan_sachin/jnj6y/

2)在不相关的控制器上使用$rootScope。 http://jsfiddle.net/VxafF/

下面是两个控制器共享服务数据的单页示例:

<!doctype html>
<html ng-app="project">
<head>
    <title>Angular: Service example</title>
    <script src="http://code.angularjs.org/angular-1.0.1.js"></script>
    <script>
var projectModule = angular.module('project',[]);

projectModule.factory('theService', function() {  
    return {
        thing : {
            x : 100
        }
    };
});

function FirstCtrl($scope, theService) {
    $scope.thing = theService.thing;
    $scope.name = "First Controller";
}

function SecondCtrl($scope, theService) {   
    $scope.someThing = theService.thing; 
    $scope.name = "Second Controller!";
}
    </script>
</head>
<body>  
    <div ng-controller="FirstCtrl">
        <h2>{{name}}</h2>
        <input ng-model="thing.x"/>         
    </div>

    <div ng-controller="SecondCtrl">
        <h2>{{name}}</h2>
        <input ng-model="someThing.x"/>             
    </div>
</body>
</html>
