我正在写一个控制器。该控制器必须与其他控制器通信。但我不知道它是否可行?
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目标:
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'
});
});

使用广播事件,我们可以将值从一个控制器传递到另一个控制器
app.controller('menuCtrl', function ($rootScope, $scope) {
$scope.Click = function () {
var valueToPass = "value";
$rootScope.$broadcast('eventMenuCtrl', valueToPass);
};
})
.controller('pageCtrl', function ($rootScope, $scope) {
$scope.getText = function () {
$scope.boldText = 'tst';
};
$scope.$on('eventMenuCtrl', function(event, value) {
$scope.boldText = value;
})
});
