问题描述
我有一个使用AngularJS的简单CRUD前端，我需要打开一个对话框，其中装有范围数据的输入。数据本身是不同的，并且需要动态的形式。保存时，我需要更新根范围数据结构。
当前，控制器范围内的项以某种方式绑定回了根范围内的数据结构。我该如何解决？我需要将这些更新的值传递给对话框结果承诺，然后将其写入根范围的数据结构。
{{name}}: <input name="{{name}}" ng-value="value" ng-model="???"/>
...
<button class="btn btn-primary" ng-click="save(???)">OK</button>
示例JS：
angular.module('ui.bootstrap.demo',['ui.bootstrap']);
angular.module('ui.bootstrap.demo').controller('ModalDemoCtrl',function ($scope,$modal,$log) {
$scope.data = [{name: 'A',url: 'example.com',interval: 5},{name: 'B',node: 'A'},{name: 'C',different:"component"}];
$scope.open = function (index) {
var modalInstance = $modal.open({
templateUrl: 'myModalContent.html',controller: 'ModalInstanceCtrl',resolve: {
item: function () {
return {index,data: $scope.data[index]};
}
}
});
modalInstance.result.then(function (item) {
console.log('result:',item);
$scope.data[item.index] = item.data
},function () {
$log.info('Modal dismissed at: ' + new Date());
});
};
});
// Please note that $modalInstance represents a modal window (instance) dependency.
// It is not the same as the $modal service used above.
angular.module('ui.bootstrap.demo').controller('ModalInstanceCtrl',$modalInstance,item) {
$scope.item = item;
console.log("dialog scope:",$scope);
$scope.save = function () {
console.log("save item: ",$scope.item);
$modalInstance.close($scope.item);
};
$scope.cancel = function () {
$modalInstance.dismiss('cancel');
};
});
