Question

I want to bind CKEditor text to ng-model text. My View:

    <form name="postForm" method="POST" ng-submit="submit()" csrf-tokenized class="form-horizontal">
  

    <fieldset>
    <legend>Post to: </legend>
    <div class="control-group">
      <label class="control-label">Text input</label>
      <div class="controls">
        <div class="textarea-wrapper">
          <textarea id="ck_editor" name="text" ng-model="text" class="fullwidth"></textarea>
        </div>
        <p class="help-block">Supporting help text</p>
      </div>
    </div>

    <div class="form-actions">
      <button type="submit" class="btn btn-primary">Post</button>
      <button class="btn">Cancel</button>
      <button class="btn" onclick="alert(ckglobal.getDate())">Cancel123</button>
    </div>
  </fieldset>
</form>

controller

      function PostFormCtrl($scope, $element, $attrs, $transclude, $http, $rootScope) {
      $scope.form = $element.find("form");
      $scope.text = "";
    
      $scope.submit = function() {
          $http.post($scope.url, $scope.form.toJSON()).
          success(function(data, status, headers, config) {
                  $rootScope.$broadcast("newpost");
                  $scope.form[0].reset();
              });
      };
    
      $scope.alert1 = function(msg) {
          var sval = $element.find("ckglobal");
          //$('.jquery_ckeditor').ckeditor(ckeditor);                                                                                                                      
          alert(sval);
      };
    }
    PostFormCtrl.$inject = ["$scope", "$element", "$attrs", "$transclude", "$http", "$rootScope"];

I want to set CKEditor value in $scope.text at the time of form submit.

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());
        });
      });
    }
  };
});
