javascript - onClick 删除按钮无需点击即可删除

Question

我创建了一个按钮来从视频标题列表中删除视频，一旦页面呈现，列表中的所有视频都会被删除。我尝试创建回调 handleSubmit，但它做同样的事情。有什么建议吗？

    handleDelete(videoId) {
        this.props.deleteVideo(videoId);
    }

    render() {
        const userVideos = this.props.videos.filter(video => video.owner_id == this.props.currentUser.id)
        const videoList = userVideos.map(video => {
            return (
                <ul key={video.id} className="user-ul">
                    <div className="user-list-item">
                        <h2 className="user-title">{video.video_title}</h2>
                        <h2 className="user-description">{video.video_description}</h2>
                        <h2 className="user-upload-date">uploaded {this.dateCreated(video.created_at)}</h2>
                    </div>
                    <button>Edit video</button>
                    <button className="delete-video" onClick={this.handleDelete(video.id)}>Delete Video</button>
                </ul>
            )
        })

        return (
            <div className="user-container">
                <h1 id="user-initial">{this.props.currentUser.username[0]}</h1>
                <ul className="user-ul">
                    {videoList}
                </ul>
                <div className="user-footer">
                    <h2 className="home-footer-1">@2020</h2>
                    <h2 className="home-footer-2">

    }

Answer 1

请尝试以下操作

onClick={() => this.handleDelete(video.id)}

这只会在点击事件发生时调用 handleDelete 方法。
