                return;
            }
        }
    };

// 修改原型
    Editor.prototype = {
        constructor: Editor,
     
        // 添加视频上传
        _initUploadVideo: function _initUploadVideo() {
            this.uploadVideo = new UploadVideo(this);
        },
        // 创建编辑器
        create: function create() {
         
            // 添加 视频上传
            this._initUploadVideo();
        },
     
    };

仅先修改了构造函数 UploadVideo,加了个插入的方法，判断改了下，后台返回的是个对象，注掉了foreach,直接\_this3.insertLinkVideo(data.url);需要后台配合写一下方法，上传地址我直接写死了，可自己修改；

补：  
主要改三部分，  
1，源码里找到Video 的构造函数 还有它的prototype，替换成我的第一部分。  
2，找到UploadImg的构造函数，还有它的prototype，这是上传图片的，相应的 你在这后面 加上我的第二部分UploadVideo的构造和原型，这是专门写的上传视频的。  
3，在Editor原型上加个方法，\_initUploadVideo , 然后在 创建编辑器 create 里面执行 this.\_initUploadVideo() ，加上就可以。  
注：uploadVideoServer，换成自己的，需要后台写个方法，我这写的只上传一个，后台只返一个对象，so我没有用forEach,成功以后直接\_this3.insertLinkVideo(data.url)，我那注释掉了forEach，看需求更改
