retrieving directive variable from the controller of the parent's parent

I am currently facing a situation involving the use of a kendo editor.

Controller One

app.controller('FirstController', ['$scope', function($scope) {
  $scope.Html = "<div> Hello World</div>";
}

Second Controller for Template

app.controller('SecondController', ['$scope', function($scope) {
 $scope.Options= [{Options1, Option2}];
}

Custom Directive

app.directive('htmlEditor', ['$http', function($http) {
    return {

        restrict: 'EA',
        replace: true,
        scope: {
            documentName: "="
        },
        link: function (scope, element, attr) {               

            $http.get("ngview/TemplateEditor.html")
            .success(function (data) {
                element.html($compile(data)(scope));                    
            });              
        }
    }

}]);

TemplateEditor.html (Using SecondController in Template)

<div ng-controller="SecondController">
<textarea kendo-editor k-ng-model="documentName" k-encoded="false" k-     
options="{{Options}}"></textarea>
 </div>

Page HTML (Utilizing FirstController)

<div ng-controller="FirstController" class="col-md-8">
    <div html-editor="HtmlEditor"
         document-name="Html">
    </div>
</div>

If I update the HTML with different text like changing "Hello World" to "Hello Every Body," it always displays the initial value that was assigned:

  $scope.Html = "<div> Hello World</div>";

Check out this JSFiddle example: https://jsfiddle.net/aqdasiftekhar/HB7LU/19160/

Answer №1

It would greatly benefit to showcase a functional demonstration of your code on plunkr in this scenario. Upon initial review, it seems that the issue lies in the following:

k-ng-model="documentName"

The correct syntax should be:

k-ng-model="{{documentName}}"

This correction will result in the resolution of documentName to Html, allowing for the binding of the textarea to $scope.Html.

Answer №2

After much effort and perseverance, I finally found a solution.

I was able to resolve the issue by updating the k-ng-model in the template file to refer to the parent (FirstController) object through the parent's parent (Directive's Scope) in the SecondController.

In TemplateEditor.html, make the following changes:

<div ng-controller="SecondController">
  <textarea kendo-editor k-ng-model="documentName" k-encoded="false" k-options="{{Options}}"></textarea>
</div>

New Code:

<div ng-controller="SecondController">
  <textarea kendo-editor k-ng-model="$parent.$parent.$parent.Html" k-encoded="false" k-options="{{Options}}"></textarea>
</div>

With this update, I no longer require the variable defined in the Directive.

scope: {
    documentName: "="
},

A big thank you to everyone who offered assistance! :-)
