对于emoveEventListener和addEventListener，没有重载与此调用匹配

问题描述

我有一个按键处理函数，定义如下：

 handleOnKeyDown = (e: React.KeyboardEvent<HTMLButtonElement>) => {
    if (key.isEscape(e.key)) {
      stopEvent(e);
      this.props.handleClose(e);
    }
  }

但是，在我的代码的另一部分中，此函数被传递给removeEventListener和addEventListener：

componentDidMount () {
    const { current: modal } = this.modalRef;
    if (modal) {
      modal.addEventListener('keydown', this.handleOnKeyDown);
    }
  }

  componentWillUnmount () {
    const { current: modal } = this.modalRef;
    if (modal) {
      modal.removeEventListener('keydown', this.handleOnKeyDown);
    }
  }

我收到以下打字稿错误：

No overload matches this call.
  Overload 1 of 2, '(type: "keydown", listener: (this: HTMLDivElement, ev: KeyboardEvent) => any, options?: boolean | EventListenerOptions | undefined): void', gave the following error.
    Argument of type '(e: React.KeyboardEvent<HTMLButtonElement>) => void' is not assignable to parameter of type '(this: HTMLDivElement, ev: KeyboardEvent) => any'.
      Types of parameters 'e' and 'ev' are incompatible.

如何解决此问题？

推荐答案

该问题似乎已回答以下问题：react typescript issue on addEvenListener

addEventListener和removeEventListener的处理函数不接受React.KeyboardEvent作为参数。它需要一个DOM事件。
