javascript - 如何在 AngularJS 中 Controller 之间进行通信？

Question

我正在编写一个 Controller 。该 Controller 必须与其他 Controller 通信。但不知道可以吗？

HTML:

<div data-ng-app="TestApp">
<div data-ng-controller="menuCtrl">
    <ul>
        <li> <a data-ng-click="Click()">
            Menü1</a>
        </li>
    </ul>
</div>
<div data-ng-controller="pageCtrl">
    <hr/> 
    <button data-ng-click="getText()">GetText</button>
    <br/>
    <strong data-ng-model="boldText"> {{boldText}}</strong>
</div>

JS:

var app = angular.module('TestApp', []);

app.controller('menuCtrl', function ($rootScope, $scope) {
    $scope.Click = function () {
    //???
    };
})
.controller('pageCtrl', function ($rootScope, $scope) {

    $scope.getText = function () {
        $scope.boldText = 'tst';
    };
});

我修复了 JSfiddle 上的示例:sample

您可以通过广播轻松实现这一点:

var app = angular.module('TestApp', []);

app.controller('menuCtrl', function ($rootScope, $scope) {
    $scope.Click = function () {
        $scope.$broadcast('MyClickEvent', {
           someProp: 'Clicking data!' // send whatever you want
        });

    };
})

.controller('pageCtrl', function ($rootScope, $scope) {

   $scope.getText = function () {
       $scope.boldText = 'tst';
   };
   $scope.$on('MyClickEvent', function (event, data) {
        console.log(data); // 'Data to send'
   });
});
