js事件对象e的ts类型校验

可以使用以下类型来校验JS事件对象e的类型：

interface MouseEvent extends UIEvent {
    readonly altKey: boolean;
    readonly button: number;
    readonly buttons: number;
    readonly clientX: number;
    readonly clientY: number;
    readonly ctrlKey: boolean;
    readonly metaKey: boolean;
    readonly movementX: number;
    readonly movementY: number;
    readonly offsetX: number;
    readonly offsetY: number;
    readonly pageX: number;
    readonly pageY: number;
    readonly relatedTarget: EventTarget | null;
    readonly screenX: number;
    readonly screenY: number;
    readonly shiftKey: boolean;
    readonly x: number;
    readonly y: number;
}

interface KeyboardEvent extends UIEvent {
    readonly altKey: boolean;
    readonly code: string;
    readonly ctrlKey: boolean;
    readonly isComposing: boolean;
    readonly key: string;
    readonly location: number;
    readonly metaKey: boolean;
    readonly repeat: boolean;
    readonly shiftKey: boolean;
}

interface UIEvent extends Event {
    readonly detail: number;
    readonly view: Window | null;
}

interface Event {
    readonly bubbles: boolean;
    cancelBubble: boolean;
    readonly cancelable: boolean;
    readonly composed: boolean;
    readonly currentTarget: EventTarget | null;
    readonly defaultPrevented: boolean;
    readonly eventPhase: number;
    readonly isTrusted: boolean;
    returnValue: boolean;
    readonly target: EventTarget | null;
    readonly timeStamp: number;
    readonly type: string;
    composedPath(): EventTarget[];
    initEvent(type: string, bubbles?: boolean, cancelable?: boolean): void;
    preventDefault(): void;
    stopImmediatePropagation(): void;
    stopPropagation(): void;
}

interface EventTarget {
    addEventListener(type: string, listener: EventListenerOrEventListenerObject | null, options?: boolean | AddEventListenerOptions): void;
    dispatchEvent(event: Event): boolean;
    removeEventListener(type: string, listener?: EventListenerOrEventListenerObject | null, options?: boolean | EventListenerOptions): void;
}

以上这些类型都是内置的TypeScript类型，可以直接使用。
