将Redactor WYSIWYG集成在AngularJs指令中

我试图将美丽的所见即所得Redactor( http://imperavi.com/redactor/)整合到一个定制的AngularJS指令中.

Visualy它的工作,但我的自定义指令是不兼容的ng模型(我不明白为什么)

这是你如何使用我的指令：

<wysiwyg ng-model="edited.comment" id="contactEditCom" content="{{content}}" required></wysiwyg>

这是指令码：

var myApp = angular.module('myApp',[]);
myApp.directive("wysiwyg",function(){

var linkFn = function(scope,el,attr,ngModel) {

    scope.redactor = null;

    scope.$watch('content',function(val) {
        if (val !== "")
        {
            scope.redactor = $("#" + attr.id).redactor({
                focus : false,callback: function(o) {
                    o.setCode(val);
                    $("#" + attr.id).keydown(function(){
                        scope.$apply(read);
                    });
                }
            });
        }
    });

    function read() {
        var content = scope.redactor.getCode();
        console.log(content);
        if (ngModel.viewValue != content)
        {
            ngModel.$setViewValue(content);
            console.log(ngModel);
        }
    }

};

 return {
     require: 'ngModel',link: linkFn,restrict: 'E',scope: {
         content: '@'
     },transclude: true
 };
});

我根据Angular-UI的TinyMCE指令做了一个.这个也听格式按钮点击.当模型在指令之外更改时,它也处理这种情况.

directive.coffee(对不起,为coffeescript)

angular.module("ui.directives").directive "uiRedactor",["ui.config",(uiConfig) ->

  require: "ngModel"
  link: (scope,elm,attrs,ngModelCtrl) ->
    redactor = null

    getVal = -> redactor?.getCode()

    apply = ->
      ngModelCtrl.$pristine = false
      scope.$apply()

    options =
      execCommandCallback: apply
      keydownCallback: apply
      keyupCallback: apply

    scope.$watch getVal,(newVal) ->
      ngModelCtrl.$setViewValue newVal unless ngModelCtrl.$pristine


    #watch external model change
    ngModelCtrl.$render = ->
      redactor?.setCode(ngModelCtrl.$viewValue or '')

    expression = if attrs.uiRedactor then scope.$eval(attrs.uiRedactor) else {}

    angular.extend options,expression

    setTimeout ->
      redactor = elm.redactor options
]

<textarea ui-redactor='{minHeight: 500}' ng-model='content'></textarea>
