2022-06-08 react window.addEventListener 无效

代码:

    componentDidMount() {
        window.addEventListener('scroll', this.handleScroll);
    }

    　　handleScroll = (e) => {

        　　console.log(e);

　　　　}

解决方案:

window.addEventListener('scroll', this.handleScroll)添加一个true,即:

window.addEventListener('scroll', this.handleScroll, true);
