将数据从Angular模态的控制器传递回主控制器 [英] Pass data from an Angular modal's controller back to the main controller

问题描述

这是事情。我无法将角度模态的数据传回我需要的控制器。下面给出的代码。

Here is the thing. I am not able to pass data from angular modal back to the controller where i need it. the codes given below.

控制器端

'use strict'
var DataMod = angular.module('Data', ["angularGrid", 'ui.bootstrap.contextMenu', 'ui.bootstrap']);
DataMod.controller('DataController', ['$scope', '$compile', '$uibModal', '$log','$rootScope', '$http', function ($scope, $compile, $uibModal,$log, $rootScope, $http, ngUtilityService) {



//user first clicks on Add button. A modal opens up. ModalInstanceCtrl is the controller used.
$scope.adduser = function () {
var modalInstance = $uibModal.open({
    templateUrl: 'myModalContent.html',
    controller: ModalInstanceCtrl
});
 //response data should be available here.  
};


var ModalInstanceCtrl = function ($scope, $uibModalInstance) {
//ajax call is made is inside this controller and i get a response. 
//this response is an object. i need to pass this object back to the adduser function. mentioned it above. 
};


}
]);

如上所示，有主控制器。我在里面使用了一个模态，它有自己的控制器。我在该模态控制器内部进行ajax调用并获得响应。

As you can see above, there is the main controller. I have used a modal inside there which has its own controller. I make ajax call inside that modals controller and get a response back.

我希望这个响应能够在adduser函数中返回，以便我可以使用该数据。但是，似乎一旦adduser函数启动，它就会转到ModalInstanceCtrl并在那里结束它的执行。它根本没有回到adduser函数。我需要一种方法来回到adduser函数。

I want that response as a result to be available back at the adduser function so that i can work with that data. However, it seems that once the adduser function starts, it goes to the ModalInstanceCtrl and ends its execution there. It doesnt come back to the adduser function at all. I need a way to get back to the adduser function.

任何人都可以让我知道如何实现这一目标。另外如何将对象响应从ModalInstanceCtrl传递到adduser函数内的主控制器。

Can anyone let me know how to achieve this. Also how to pass the object response from ModalInstanceCtrl to the main controller inside adduser function.

推荐答案

看起来你正在使用Angular Bootstrap Modal，是吗？首先，我将其设置为使模态控制器与主控制器分离。其次，您错过了将响应从模态传递到主控制器所需的承诺。您可以在此处阅读文档中的返回模式实例： https：// angular-ui。 github.io/bootstrap/#/modal

It looks like you are using the Angular Bootstrap Modal, yes? First, I would set it up so that the modal controller is separated out from the main controller. Second, you are missing the promise needed to pass the response from the modal to the main controller. You can read about the return modal instance in the docs here: https://angular-ui.github.io/bootstrap/#/modal

这是Angular Bootstrap plunkr的示例代码： http://plnkr.co/edit/nGjBtMp33pFDAQ6r7Tew?p=info

This is the example code from the Angular Bootstrap plunkr: http://plnkr.co/edit/nGjBtMp33pFDAQ6r7Tew?p=info

angular.module('ui.bootstrap.demo', ['ngAnimate', 'ui.bootstrap']);
angular.module('ui.bootstrap.demo').controller('ModalDemoCtrl', function ($scope, $uibModal, $log) {

  $scope.items = ['item1', 'item2', 'item3'];

  $scope.animationsEnabled = true;

  $scope.open = function (size) {

var modalInstance = $uibModal.open({
  animation: $scope.animationsEnabled,
  templateUrl: 'myModalContent.html',
  controller: 'ModalInstanceCtrl',
  size: size,
  resolve: {
    items: function () {
      return $scope.items;
    }
  }
});

modalInstance.result.then(function (selectedItem) {
  $scope.selected = selectedItem;
}, function () {
  $log.info('Modal dismissed at: ' + new Date());
});
};
  $scope.toggleAnimation = function () {
    $scope.animationsEnabled = !$scope.animationsEnabled;
  };

});

// Please note that $uibModalInstance represents a modal window (instance) dependency.
// It is not the same as the $uibModal service used above.

angular.module('ui.bootstrap.demo').controller('ModalInstanceCtrl', function ($scope, $uibModalInstance, items) {

  $scope.items = items;
  $scope.selected = {
    item: $scope.items[0]
  };

  $scope.ok = function () {
    $uibModalInstance.close($scope.selected.item);
  };

  $scope.cancel = function () {
    $uibModalInstance.dismiss('cancel');
  };
});
