  * 成功：
  * this.subject.destroy('onOk');
  *  若需要回调用参数则：
  *  this.subject.next(data);
  *  this.subject.destroy();
  *
  * 关闭：
  * this.subject.destroy();
  *
  * @param {*} comp 组件
  * @param {*} [params] 组件参数
  * @param {('sm' | 'lg' | '' | number)} [size='lg'] 大小；例如：lg、600，默认：lg
  * @param {*} [options] 对话框ConfigInterface参数
