javascript - react : How to hide a component by clicking on it?

Question

我试图通过单击 React 组件来隐藏它，但我在网上看到的只是有关按钮等事件处理程序的解释。

我正在使用 Next.js(但我认为这些对此没有多大意义)。

这是我的组件:

import styles from './styles/popup.module.scss';
import React, { Component } from "react";


export default function Popup() {
    return (
        <div className={styles.popup}>
            <div className={styles.popupInner}>
                <h1>Temporary Closure</h1>
                <p>
                    Following the Australian government’s directive to keep our nation safe and limit the spread of Coronavirus (Covid-19), it is with great sadness that we advise that SS will be temporarily closed, effective 23<sup>rd</sup> March 2020
                </p>                    
            </div>
        </div>
    )
}

尝试在单击组件时设置状态。下面的代码应该可以工作。

import styles from './styles/popup.module.scss';
import React, { Component } from "react";


export default function Popup() {

    const [visible, setVisible] = React.useState(true);

    if(!visible) return null;

    return (
        <div className={styles.popup} onClick={() => setVisible(false)}>
            <div className={styles.popupInner}>
                <h1>Temporary Closure</h1>
                <p>
                    Following the Australian government’s directive to keep our nation safe and limit the spread of Coronavirus (Covid-19), it is with great sadness that we advise that sydney sauna will be temporarily closed, effective 23<sup>rd</sup> March 2020
                </p>
                <div className={styles.buttonContainer}><button className={styles.button}>Okay</button></div>

            </div>
        </div>
    )
}

希望有帮助。
