Error in AngularJS when passing object to modal dialog

I'm facing a challenge with an AngularJS application I'm developing. It involves displaying a list of contacts, each accompanied by a button that triggers a modal containing a form for editing the contact information. The issue arises when attempting to edit the existing information as it fails to display in the form. I suspect this could be due to the modal not inheriting the scope from the parent page. Despite various attempts to resolve it by modifying input field attributes, such as prepending ng-model with $parent and using ng-init, the problem persists. Any guidance from experienced individuals here would be greatly appreciated.

Thank you in advance.

Let me provide you with a snippet of my code to give you a better understanding of the context. Here is the HTML responsible for rendering the contacts list:

<div class="panel panel-default" ng-controller="contactsController">
<div class="panel-body">
    <div id="gridContainer" ng-class="{'': state == 'list', 'none': state != 'list'}">
        <table class="table table-bordered table-striped">
            <thead>
            <tr>
                <th scope="col"><spring:message code="contacts.name"/></th>
                <th scope="col"><spring:message code="contacts.email"/></th>
                <th scope="col"><spring:message code="contacts.phone"/></th>
                <th scope="col"></th>
            </tr>
            </thead>
            <tbody>
            <tr ng-repeat="contact in page.source">
                <td class="tdContactsCentered">{{contact.name}}</td>
                <td class="tdContactsCentered">{{contact.email}}</td>
                <td class="tdContactsCentered">{{contact.phoneNumber}}</td>
                <td class="width15">
                    <div class="text-center">
                        <input type="hidden" value="{{contact.id}}"/>
                        <a ng-href="#updateContactsModal"
                           ng-click="selectedContact(contact);"
                           role="button"
                           title="<spring:message code="update"/>&nbsp;<spring:message code="contact"/>"
                           class="btn btn-sm btn-warning" data-toggle="modal">
                            <i class="icon-pencil"></i>
                        </a>
                        <a ng-href="#deleteContactsModal"
                           ng-click="selectedContact(contact);"
                           role="button"
                           title="<spring:message code="delete"/>&nbsp;<spring:message code="contact"/>"
                           class="btn btn-sm btn-danger" data-toggle="modal">
                            <em class="fa fa-trash"></em>
                        </a>
                    </div>
                </td>
            </tr>
            </tbody>
        </table>
    </div>
</div>

Next, let's explore the HTML markup defining the modal and the editing form:

<div id="updateContactsModal"
 class="modal fade centering"
 role="dialog"
 aria-labelledby="updateContactsModalLabel"
 aria-hidden="true" style="display: none;">
<div class="modal-dialog" role="document">
    <div class="modal-content">
<div class="modal-header">
    <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button>
    <h3 id="updateContactsModalLabel" class="modal-title">
        <spring:message code="update"/>&nbsp;<spring:message code="contact"/>
    </h3>
</div>
<div class="modal-body" data-ng-controller="contactsController">
    <form name="updateContactForm" novalidate>
        <input type="hidden"
               required
             data-ng-model="contact.id"
               name="id"
               value="{{contact.id}}"/>
        <div>
            ... <!-- Form fields for updating contact information -->
        </div>
    </form>
    <div class="modal-footer">
        ... <!-- Buttons for submitting updates and canceling -->
    </div>
</div>

<span class="alert alert-error dialogErrorMessage"
      ng-show="errorOnSubmit">
    <spring:message code="request.error"/>
</span>
</div><!-- /.modal-content -->
</div><!-- /.modal-dialog -->

Finally, let's take a look at the relevant portions of the controller logic:

App.controller('contactsController', ["$scope", "$http", function($scope,$http) {

... <!-- Controller functions for retrieving, updating, and managing contact data -->

}]);

Answer №1

The reason the modal does not share the same scope as the contacts table is because Angular creates a new scope each time it encounters an ng-controller directive.

In both the contacts table and the modal, you are declaring ng-scope, resulting in Angular creating separate scopes.

For more detailed information, refer to this answer:

There are several ways to address this issue...

1) Place the modal HTML inside the parent element where ng-controller is initially declared - this way, it will be within the same scope.

2) Utilize UI Bootstrap's modal directive to create the modal with its own controller and pass in $scope.contact from your contactsController. You can find an example here: https://angular-ui.github.io/bootstrap/#/modal

3) Develop a service that stores $scope.contact and inject it into a separate controller specifically created for the modal. Check out this fiddle for an illustration: http://jsfiddle.net/whnSs/
