[英]Angular.js: Data binding not working with directives controller option
[英]Angular JS / Data Binding / Controller
我有两个控制器和一项服务。 有人可以解释一下为什么姓氏不会更新/更改时引用是“旧的”吗?
我以为这是控制器之间进行通信的方式...?
<!-- language: lang-js -->
// Controller 1
function controllerOne (..., myService) {
$scope.firstname = myService.customer.firstname;
}
// Controller 2
function controllerTwo (..., myService) {
$scope.firstnameNew = myService.customer.firstname;
}
// Service
application.factory('myService', ...)
function(...) {
return {
customer: {
"firstname": "",
"lastname": "",
"pers": "",
"street": "",
"zip": "",
"city": "",
"selectedCountry": "",
"comment": ""
},
...
}
在控制器之间进行通讯时,请检查以下提示。
var myModule = angular.module('myModule', []);
myModule.factory('mySharedService', function($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 = ['$scope', 'mySharedService'];
<body data-ng-app="myApp">
<div data-ng-controller="ctrl1">
{{firstName}}
{{lastName}}
</div>
<div data-ng-controller="ctrl2">
{{firstName}}
{{lastName}}
</div>
</body>
Script :
var myApp= angular.module('myApp', []);
myApp.controller('ctrl1', function ($scope, myService) {
$scope.firstName = myService.firstName;
$scope.lastName = myService.lastName;
myService.firstName = "ABC";
myService.lastName = "DEF";
});
myApp.controller('ctrl2', function ($scope, myService) {
$scope.firstName = myService.firstName;
$scope.lastName = myService.lastName;
});
myApp.factory('myService', function ($rootScope) {
return {
firstName: '123',
lastName: '456'
};
});
