如何将我选中的项目存储在带有其他控制器的复选框中?
我的尝试(请参阅the plnkr了解观点):
var myApp = angular.module('myApp', []);
myApp.factory('CooSelection', function () {
return {selectedCoo: []}
})
function CooListCtrl($scope, CooSelection) {
$scope.coos = {"Coos": ["spark", "nark", "hark", "quark"]};
$scope.coo_list_selection = CooSelection;
$scope.checkSelection = function (item) {
if ($scope.coo_list_selection.indexOf(item) === -1) {
$scope.coo_list_selection.push(item);
} else {
$scope.coo_list_selection.splice($scope.coo_list_selection.lastIndexOf(item), 1);
}
}
}
CooListCtrl.$inject = ['$scope', 'CooSelection'];
function DebugCooList($scope, CooSelection) {
$scope.coo_selection = CooSelection;
}
DebugCooList.$inject = ['$scope', 'CooSelection'];

当您引用CooSelection
服务时,您期望一个数组,但工厂返回一个对象。你可以这样做:
myApp.factory('CooSelection', function () {
return []; // Return an array instead of an object.
})
此外,在DebugCooList
控制器中,您的scope属性与您在视图中检查的变量的名称不匹配。控制器代码分配给coo_selection
,但视图会检查coo_list_selection
,因此您需要更改一个以匹配另一个。
