angularjs 与 UEditor开发，添加directive，保证加载顺序正常

'use strict';

angular.module('app.core').directive('ueditor', [function () {

    return {

        restrict: 'A',

        require: 'ngModel',

        link: function (scope, element, attrs, ctrl) {

            var _initContent = '';

            var editor;

            var editorReady = false;

            ctrl.$render = function () {

                _initContent = ctrl.$isEmpty(ctrl.$viewValue) ? '' : ctrl.$viewValue;

                setContent(_initContent);

            };

            function init() {

                editor = new UE.ui.Editor({

                    initialContent: scope.content,

                    wordCount: false, // 字数统计

                    toolbars: [

                    setContent(_initContent);

                    editor.addListener('contentChange', function () {

        }

    };

}]);

<div name="content" ueditor ng-model="content" ng-change="contentChanged()" ng-required="true"></div>

初始化 $scope.content="";

赋值：$scope.content="<b>abcdefg</b>"
