typescript - 无法让粘贴事件在 Typescript 中工作

Question

我有这个 Typescript 代码:

const pasteFn = (e: ClipboardEvent) => {
    const { clipboardData } = e;
    const text = clipboardData?.getData('text/plain');
    console.log(text);
};

window.addEventListener('paste', pasteFn);

我疯狂地搜索并尝试了所有示例，但我不明白我得到的错误:

No overload matches this call.
  Overload 1 of 2, '(type: keyof WindowEventMap, listener: (this: Window, ev: Event | DeviceMotionEvent | DeviceOrientationEvent | GamepadEvent | ... 23 more ... | StorageEvent) => any, options?: boolean | ... 1 more ... | undefined): void', gave the following error.
    Argument of type '"paste"' is not assignable to parameter of type 'keyof WindowEventMap'.
  Overload 2 of 2, '(type: string, listener: EventListenerOrEventListenerObject, options?: boolean | AddEventListenerOptions | undefined): void', gave the following error.
    Argument of type '(e: ClipboardEvent) => void' is not assignable to parameter of type 'EventListenerOrEventListenerObject'.
      Type '(e: ClipboardEvent) => void' is not assignable to type 'EventListener'.
        Types of parameters 'e' and 'evt' are incompatible.
          Property 'clipboardData' is missing in type 'Event' but required in type 'ClipboardEvent'.ts(2769)
lib.dom.d.ts(3747, 14): 'clipboardData' is declared here.

粘贴事件在文档上可用，在窗口上不可用。 使用:

window.document.addEventListener('paste', pasteFn);

paste 在接口(interface) DocumentAndElementEventHandlersEventMap 中定义:

interface DocumentAndElementEventHandlersEventMap {
    "copy": ClipboardEvent;
    "cut": ClipboardEvent;
    "paste": ClipboardEvent;
}

此接口(interface)由 HTMLEventMap 和 DocumentEventMap 扩展，而不是由 WindowEventMap 扩展
