[英]Sharing Data Between Controllers using Services in Angular js
通過服務在控制器之間共享
我已經瀏覽了鏈接和視頻
我有一個活着的打工者,同樣在這里看到打工者
JAVASCRIPT
var testModule = angular.module('testmodule', []); testModule .controller('QuestionsStatusController1', ['$rootScope', '$scope', 'myservice', function ($rootScope, $scope, myservice) { $scope.myserviceCopy = myservice; $scope.myserviceCopy.newValue = $scope.NotBinding; myservice.confirming = "asdsadasdd"; $scope.ForceBinding = function(){ $scope.myserviceCopy.newValue = $scope.NotBinding; }; }]); testModule .controller('QuestionsStatusController2', ['$rootScope', '$scope', 'myservice', function ($rootScope, $scope, myservice) { $scope.myservice = myservice; $scope.newMyService = myservice; }]); testModule .service('myservice', function() { this.xxx = "yyy"; });
(在插栓中)“ 1”工作正常,並立即更新
當我按下bindNow按鈕時,“ 2”僅在更新
“ 3”根本沒有更新
我只希望它們所有人都立即刷新,並且我不想使用“ 1”方式(在插塞器中)
我知道我一定會在概念上與我所感知的有所不同。
我不確定為什么您要創建許多服務副本,因此簡化了代碼,並且我認為它應該可以按預期工作:
js
var testModule = angular.module('testmodule', []);
testModule
.controller('QuestionsStatusController1',
['$rootScope', '$scope', 'myservice',
function ($rootScope, $scope, myservice) {
$scope.myservice = myservice;
$scope.myservice.confirming = "asdsadasdd";
$scope.ForceBinding = function(){
$scope.myservice.newValue = $scope.NotBinding;
};
$scope.$watch("NotBinding",
function( newValue, oldValue ) {
$scope.myservice.newValue = newValue;
}
);
$scope.$watch("confirming",
function( newValue, oldValue ) {
$scope.myservice.confirming = newValue;
}
);
}]);
testModule
.controller('QuestionsStatusController2',
['$rootScope', '$scope', 'myservice',
function ($rootScope, $scope, myservice) {
$scope.myservice = myservice;
}]);
testModule
.service('myservice', function() {
this.xxx = "yyy";
});
和html:
<!DOCTYPE html>
<html ng-app="testmodule">
<head>
<script data-require="angular.js@1.1.5" data-semver="1.1.5" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.1.5/angular.js"></script>

檢查代碼和我的代碼之間的差異,您會發現問題所在,例如,控制器1的div在數字3之前關閉了(這就是為什么它沒有被更新的原因)。
您可以在這個笨拙的工具中看到它。
