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。

下面是一个与Angular JS无关的发布-订阅方法。

搜索参数控制器

//Note: Multiple entities publish the same event
regionButtonClicked: function () 
{
        EM.fireEvent('onSearchParamSelectedEvent', 'region');
},

plantButtonClicked: function () 
{
        EM.fireEvent('onSearchParamSelectedEvent', 'plant');
},

搜索选择控制器

//Note: It subscribes for the 'onSearchParamSelectedEvent' published by the Search Param Controller
localSubscribe: function () {
        EM.on('onSearchParamSelectedEvent', this.loadChoicesView, this);

});


loadChoicesView: function (e) {

        //Get the entity name from eData attribute which was set in the event manager
        var entity = $(e.target).attr('eData');

        console.log(entity);

        currentSelectedEntity = entity;
        if (entity == 'region') {
            $('.getvalue').hide();
            this.loadRegionsView();
            this.collapseEntities();
        }
        else if (entity == 'plant') {
            $('.getvalue').hide();
            this.loadPlantsView();
            this.collapseEntities();
        }


});

事件管理器

myBase.EventManager = {

    eventArray:new Array(),


    on: function(event, handler, exchangeId) {
        var idArray;
        if (this.eventArray[event] == null) {
            idArray = new Array();
        } else { 
            idArray = this.eventArray[event];
        }
        idArray.push(exchangeId);
        this.eventArray[event] = idArray;

        //Binding using jQuery
        $(exchangeId).bind(event, handler);
    },

    un: function(event, handler, exchangeId) {

        if (this.eventArray[event] != null) {
            var idArray = this.eventArray[event];
            idArray.pop(exchangeId);
            this.eventArray[event] = idArray;

            $(exchangeId).unbind(event, handler);
        }
    },

    fireEvent: function(event, info) {
        var ids = this.eventArray[event];

        for (idindex = 0; idindex < ids.length; idindex++) {
            if (ids[idindex]) {

                //Add attribute eData
                $(ids[idindex]).attr('eData', info);
                $(ids[idindex]).trigger(event);
            }
        }
    }
};

全球

var EM = myBase.EventManager;

我也知道这条路。

angular.element($('#__userProfile')).scope().close();

但我不太使用它，因为我不喜欢在angular代码中使用jQuery选择器。

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.

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'];

控制器之间有多种通信方式。

最好的可能是共享服务:

function FirstController(someDataService) 
{
  // use the data service, bind to template...
  // or call methods on someDataService to send a request to server
}

function SecondController(someDataService) 
{
  // has a reference to the same instance of the service
  // so if the service updates state for example, this controller knows about it
}

另一种方法是在作用域上释放事件:

function FirstController($scope) 
{
  $scope.$on('someEvent', function(event, args) {});
  // another controller or even directive
}

function SecondController($scope) 
{
  $scope.$emit('someEvent', args);
}

在这两种情况下，您也可以与任何指令通信。
