Bind Ckeditor value to model text in AngularJS and Rails

If you simply want to retrieve text in the editor textarea in angular, call CKEDITOR.instances.editor1.getData(); to get the value directly in an angularjs function. See below.

In your html

In the test.controller.js

(function () {
    'use strict';

    angular
        .module('app')
            .controller('test', test);

    test.$inject = []; 

    function test() {

        //this is to replace $scope
        var vm = this;

        //function definition
        function postJob()
        {          
            vm.Description = CKEDITOR.instances.editor1.getData();
            alert(vm.Description);
        }
    } 
})();

the Vojta answer work partly

in this post I found a solution

the final code:

.directive('ckEditor', function() {
                return {
                    require : '?ngModel',
                    link : function($scope, elm, attr, ngModel) {

                        var ck = CKEDITOR.replace(elm[0]);

                        ck.on('instanceReady', function() {
                            ck.setData(ngModel.$viewValue);
                        });

                        ck.on('pasteState', function() {
                            $scope.$apply(function() {
                                ngModel.$setViewValue(ck.getData());
                            });
                        });

                        ngModel.$render = function(value) {
                            ck.setData(ngModel.$modelValue);
                        };
                    }
                };
            })

edit: removed unused brackets

CKEditor does not update textarea while typing, so you need to take care of it.

Here's a directive that will make ng-model binding work with CK:

angular.module('ck', []).directive('ckEditor', function() {
  return {
    require: '?ngModel',
    link: function(scope, elm, attr, ngModel) {
      var ck = CKEDITOR.replace(elm[0]);

      if (!ngModel) return;

      ck.on('pasteState', function() {
        scope.$apply(function() {
          ngModel.$setViewValue(ck.getData());
        });
      });

      ngModel.$render = function(value) {
        ck.setData(ngModel.$viewValue);
      };
    }
  };
});

In html, just use:

<textarea ck-editor ng-model="value"></textarea>

---

The previous code will update ng-model on every change.

If you only want to update binding on save, override "save" plugin, to not do anything but fire "save" event.

// modified ckeditor/plugins/save/plugin.js
CKEDITOR.plugins.registered['save'] = {
  init: function(editor) {
    var command = editor.addCommand('save', {
      modes: {wysiwyg: 1, source: 1},
      readOnly: 1,
      exec: function(editor) {
        editor.fire('save');
      }
    });

    editor.ui.addButton('Save', {
      label : editor.lang.save,
      command : 'save'
    });
  }
};

And then, use this event inside the directive:

angular.module('ck', []).directive('ckEditor', function() {
  return {
    require: '?ngModel',
    link: function(scope, elm, attr, ngModel) {
      var ck = CKEDITOR.replace(elm[0]);

      if (!ngModel) return;

      ck.on('save', function() {
        scope.$apply(function() {
          ngModel.$setViewValue(ck.getData());
        });
      });
    }
  };
});
