Angular UI Bootstrap modal inside ngRepeat

问题

I am making an app, where I have a lot of input fields. Those input fields are generated from JSON object array field with AngularJS ngRepeat directive and have a button next to them which open an Angular UI Bootstrap modal to edit this value in a bigger textarea. I cannot figure out how to reference this model property to Angular UI Bootstrap so that I can save the changes made in modal. Since this functionality is needed in multiple views, I turned it into a service.

I have made a plunker to illustrate my problem.

Currently in plunker example modal contains textarea, but I will actually need to use Text-Angular directive, because those fields contain some HTML markup and I would be easier for users to edit values with this nice addon.

TextAngular

EDIT: Please, if you are taking time to answer, you might aswell take a little more time to edit my plunker example to show exactly how your solution would look like, because seems that everyone who tries to help me, think they know the solution, but in reality it doesn't work :( Thanks!

I personally like to decorate my $scope with the services (i.e. $scope.modalService = ModalService;), so I understand the source of the logic. In the ng-repeat you then pass the value item into the method call:

<div class="input-group">
    <input class="form-control" ng-model="value.value">
    <span class="input-group-addon" ng-click="modalService.openTextEditModal(value)">
       <span class="glyphicon glyphicon-align-justify"></span>
    </span>
</div>

The modal service and modal template would then reference the object, in this case a clone of the object to help with state management, not the text:

app.factory('ModalService', function($modal) {
    return {
        openTextEditModal: function(item) {
            var modalInstance = $modal.open({
                templateUrl: 'modal.html',
                backdrop: 'static',
                controller: function($scope, $modalInstance, $sce, item) {
                    var clone = {};
                    angular.copy(item, clone);
                    $scope.clone = clone;
                    $scope.close = function() {
                        $modalInstance.dismiss('cancel');
                    };
                    $scope.save = function() {
                      angular.extend(item, clone);
                      $modalInstance.close();
                    };
                },
                size: 'lg',
                resolve: {
                    item: function() {
                        return item;
                    }
                }
            });

        }
    };
});

With the corresponding modal template changes:

<div class="modal-header">
    <h3 class="modal-title">Edit text</h3>
</div>
<div class="modal-body">
    <textarea class="form-control" ng-model="clone.value"></textarea>
</div>
<div class="modal-body">
    <button class="btn btn-warning" ng-click="close()">Close</button>
    <button class="btn btn-success pull-right" ng-click="save()">Save</button>
</div>

It might be easier to make a controller for your modal and pass in the objects that you need from your scope. Those will be passed by reference so changes to them will update the scope of your parent scope. Something like this in your MainCtrl :

 var modalInstance = ModalService.open({
            templateUrl: 'modal.html',
            controller: 'YourModalController',
            size: 'lg',
            resolve: {
                text: function () {
                    return $scope.editText;
                }
           }
        });

        modalInstance.result.then(function () {
        });

And then in your modal controller:

app.controller('YourModalController', ['$scope', '$modalInstance', 'text', function YourModalController($scope, $modalInstance, text) {

 $scope.text = text;
                    $scope.close = function() {
                        $modalInstance.dismiss('cancel');
                    };
                    $scope.save = function() {
                        $modalInstance.close($scope.text);
                    };

}]);

And if you want it to be reusable so you do not have to duplicate the modal instance code in the parent controller you could make that a directive.

回答3:

You can return the promise and then handle the success callback in the controller.

In the openTextEditModal function, return modalInstance.result;.

Then, in the controller you can do this:

$scope.editText = function(text){
    ModalService.openTextEditModal(text).then(function(newText){
        console.log(newText);
        $scope.text = newText; // do something with the new text
    });
};
