在 React Typescript 中创建自定义按钮并添加 onClick 事件

Question

我正在尝试在使用 React Hooks 和 Styled 组件的 React Typescript 项目中创建自定义按钮组件。

// Button.tsx
import React, { MouseEvent } from "react";
import styled from "styled-components";

export interface IButtonProps {
    children?: React.ReactNode;
    props?: any;
    onClick?:
        | ((event: React.MouseEvent<HTMLButtonElement, MouseEvent>) => void)
        | undefined;
}

const Button: React.FC<IButtonProps> = ({
    children,
    onClick = () => {},
    ...props
}) => {
    const handleOnClick = (e: MouseEvent<HTMLButtonElement>) => {
        onClick(e);
    };
    return (
        <ButtonStyles onClick={handleOnClick} {...props}>
            {children}
        </ButtonStyles>
    );
};

export default Button;

const ButtonStyles = styled.button``;

这是我想使用自定义按钮的组件

// Login.tsx
import React from "react";
import Button from "../../components/Generic/Button/Button";

const Login: React.FC = () => {
    const clickMe = () => {
        console.log("Button Clicks");
    };

    return (
        <div>
            <Button onClick={clickMe}>My Button</Button>
        </div>
    );
};

export default Login;

我想单击我的自定义按钮并在单击它时打印控制台日志消息。但我收到以下错误。如何解决这个问题？

Argument of type 'MouseEvent<HTMLButtonElement, MouseEvent>' is not assignable to parameter of type 'MouseEvent<HTMLButtonElement, MouseEvent<Element, MouseEvent>>'.
  Type 'MouseEvent' is missing the following properties from type 'MouseEvent<Element, MouseEvent>': nativeEvent, isDefaultPrevented, isPropagationStopped, persist  TS2345

    17 |    const handleOnClick = (e: MouseEvent<HTMLButtonElement>) => {
  > 18 |        onClick(e);
       |                ^
    19 |    };
    20 |    return (
    21 |        <ButtonStyles onClick={handleOnClick} {...props}>

Answer 1

您的接口IButtonProps定义了预期的签名onClick

    onClick?:
        | ((event: React.MouseEvent<HTMLButtonElement, MouseEvent>) => void)
        | undefined;

然而，e参数 的handleClick定义不同：MouseEvent<HTMLButtonElement>

如果您更改 onClick 签名以匹配您的handleClick定义，这可能会以某种方式解决它？

    onClick?:
        | ((event: React.MouseEvent<HTMLButtonElement>) => void)
        | undefined;

import * as React from "react";


export interface ButtonProps extends React.ButtonHTMLAttributes<HTMLButtonElement> {}


/**
 * Button.
 *
 * @param {ButtonProps} props button's props
 * @returns {React.ReactElement<ButtonProps>} Button.
 */
export function Button(props: ButtonProps): React.ReactElement<ButtonProps> {
    const { children, ...rest } = props;
    return (
        <button
            {...rest}
        >
            {children}
        </button>
    );
}
