我想将ckeditor文本绑定到ng-model文本

我的看法

<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>

调节器

  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"];

我想在表单提交时在$ scope.text中设置ckeditor值

答案

键入时CKEditor不会更新textarea,因此您需要处理它。

这是一个使ng-model绑定与CK协同工作的指令:

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);
      };
    }
  };
});

html中,只需使用:

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

以前的代码将在每次更改时更新ng-model。

如果您只想更新保存时的绑定,请覆盖“保存”插件,除了触发“保存”事件外什么都不做。

// 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'
    });
  }
};

然后,在指令中使用此事件:

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

在这篇文章中,我找到了解决方案

最终代码:

.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);
                        };
                    }
                };
            })

另一答案

如果您只想在编辑器textarea中以角度检索文本,请调用CKEDITOR.instances.editor1.getData();直接在angularjs函数中获取值。见下文。

在你的HTML中

在test.controller.js中

(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);
        }
    } 
})();
另一答案

感谢Vojta的出色指令。有时它不会加载。这是修复该问题的修改版本。

angular.module('ck', []).directive('ckEditor', function() {
  var calledEarly, loaded;
  loaded = false;
  calledEarly = false;

  return {
    require: '?ngModel',
    compile: function(element, attributes, transclude) {
      var loadIt, local;

      local = this;
      loadIt = function() {
        return calledEarly = true;
      };

      element.ready(function() {
        return loadIt();
      });

      return {
        post: function($scope, element, attributes, controller) {
          if (calledEarly) {
            return local.link($scope, element, attributes, controller);
          }
          loadIt = (function($scope, element, attributes, controller) {
            return function() {
              local.link($scope, element, attributes, controller);
            };
          })($scope, element, attributes, controller);
        }
      };
    },

    link: function($scope, elm, attr, ngModel) {
      var ck;
      if (!ngModel) {
        return;
      }

      if (calledEarly && !loaded) {
        return loaded = true;
      }
      loaded = false;

      ck = CKEDITOR.replace(elm[0]);
      ck.on('pasteState', function() {
        $scope.$apply(function() {
          ngModel.$setViewValue(ck.getData());
        });
      });

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

或者如果你需要coffeescript

angular.module('ck', []).directive('ckEditor', ->
  loaded = false
  calledEarly = false
  {
    require: '?ngModel',
    compile: (element, attributes, transclude) ->
      local = @
      loadIt = ->
        calledEarly = true

      element.ready ->
        loadIt()
      post: ($scope, element, attributes, controller) ->
        return local.link $scope, element, attributes, controller if calledEarly

        loadIt = (($scope, element, attributes, controller) ->
          return ->
            local.link $scope, element, attributes, controller
        )($scope, element, attributes, controller)
    link: ($scope, elm, attr, ngModel) ->
      return unless ngModel

      if (calledEarly and not loaded)
        return loaded = true
      loaded = false

      ck = CKEDITOR.replace(elm[0])

      ck.on('pasteState', ->
        $scope.$apply( ->
          ngModel.$setViewValue(ck.getData())
        )
      )

      ngModel.$render = (value) ->
        ck.setData(ngModel.$viewValue)
  }
)
另一答案

只是为了记录如果你想在一个页面中使用多个编辑器,这可以派上用场:

mainApp.directive('ckEditor', function() {
    return {
        restrict: 'A', // only activate on element attribute
        scope: false,
        require: 'ngModel',
        controller: function($scope, $element, $attrs) {}, //open for now
        link: function($scope, element, attr, ngModel, ngModelCtrl) {
            if(!ngModel) return; // do nothing if no ng-model you might want to remove this
            element.bind('click', function(){
                for(var name in CKEDITOR.instances)
                    CKEDITOR.instances[name].destroy();
                var ck = CKEDITOR.replace(element[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.$viewValue);
                };
            });
        }
    }
});

这将销毁所有先前的ckeditor实例并创建一个新实例。

另一答案

现在有一个可以用于此的'变更'事件。

这是我刚刚创建的一个指令,它有几个不同的工具栏配置选项,我正在使用jQuery适配器来初始化ckeditor。欲了解更多信息,请查看this blog post

(function () {
    'use strict';

    angular
        .module('app')
        .directive('wysiwyg', Directive);

    function Directive($rootScope) {
        return {
            require: 'ngModel',
            link: function (scope, element, attr, ngModel) {
                var editorOptions;
                if (attr.wysiwyg === 'm
