TypeScript和Backbone;使用className作为函数？

Question

我正在扩展一个Backbone类（View），我的类已经将className定义为在运行时进行评估的函数（根据Backbone规范，这是一个可接受的选项）。

但是，index.d.ts仅将className定义为字符串。

我是否可以扩展到定义以允许className成为函数？

提前感谢...

class View<TModel extends Model> extends Events {

    /**
    * Do not use, prefer TypeScript's extend functionality.
    **/
    private static extend(properties: any, classProperties?: any): any;

    constructor(options?: ViewOptions<TModel>);
    initialize(options?: ViewOptions<TModel>): void;

    /**
    * Events hash or a method returning the events hash that maps events/selectors to methods on your View.
    * For assigning events as object hash, do it like this: this.events = <any>{ "event:selector": callback, ... };
    * That works only if you set it in the constructor or the initialize method.
    **/
    events(): EventsHash;

    $(selector: string): JQuery;
    model: TModel;
    collection: Collection<TModel>;
    //template: (json, options?) => string;
    setElement(element: HTMLElement|JQuery, delegate?: boolean): View<TModel>;
    id: string;
    cid: string;
    className: string;
    tagName: string;

    el: any;
    $el: JQuery;
    setElement(element: any): View<TModel>;
    attributes: any;
    $(selector: any): JQuery;
    render(): View<TModel>;
    remove(): View<TModel>;
    make(tagName: any, attributes?: any, content?: any): any;
    delegateEvents(events?: EventsHash): any;
    delegate(eventName: string, selector: string, listener: Function): View<TModel>;
    undelegateEvents(): any;
    undelegate(eventName: string, selector?: string, listener?: Function): View<TModel>;

    _ensureElement(): void; }
