我无法弄清楚如何从子作用域(ModalCtrl)更新父作用域(DirCrl)中的$scope.dir.视图是一个简单的模态形式,只有一个文本输入.提交时,文本输入绑定到子范围中的mkdir.name.子控制器对数据库进行REST调用,并应使用响应数据更新父作用域中的$scope.dir.任何指导将不胜感激.下面的代码片段
app.controller('DirCtrl',['$scope','$http',function ($scope,$http) {
$scope.dir = {};
$scope.mySelections = [];
$http({
method: 'GET',url: '//localhost:9090/fx/v1/dir/52cdc7304c3525ac0c5cdd3a'
})
.success(function (data,status,headers,config) {
$scope.dir = data;
$scope.children = data.children;
})
.error(function (data,config) {
});
}]);
var ModalCtrl = function ($scope,$modal,$log) {
$scope.mkdir = {
name: 'name',data: {}
};
$scope.$parent.ben = 'ben01';
$scope.open = function () {
var modalInstance = $modal.open({
templateUrl: 'myModalContent.html',backdrop: true,windowClass: 'modal',controller: ModalInstanceCtrl,resolve: {
mkdir: function () {
return $scope.mkdir;
}
}
});
modalInstance.result.then(function () {
$scope.$parent.children = $scope.mkdir.data.children;
});
};
};
var ModalInstanceCtrl = function ($scope,$modalInstance,$http,$log,mkdir) {
$scope.mkdir = mkdir;
$scope.submit = function () {
$log.log('name of directory to create');
$log.log(mkdir.name);
$http({
method: 'GET',url: '//localhost:9090/fx/v1/dir/52cdcce74c358cdfe2fa2c83'
})
.success(function (data,config) {
$scope.mkdir.data = data;
})
.error(function (data,config) {
});
$modalInstance.dismiss('cancel');
}
$scope.cancel = function () {
$modalInstance.dismiss('cancel');
};
};
更正：
在孩子做类似的事情：
$scope.$emit('whatevereventnameyouwant',data);
在父母听取该事件：
$rootScope.$on('whatevereventnameyouwant',function(event,data) { console.log(data); });
