我有创建<li>元素的代码。我需要通过点击一一删除元素。对于我拥有的每个元素Delete button。我知道我需要一些功能来删除项目id。如何做这个功能来删除 ReactJS 中的元素？我的代码：

class TodoApp extends React.Component {
    constructor(props) {
        super(props);
        this.handleChange = this.handleChange.bind(this);
        this.handleSubmit = this.handleSubmit.bind(this);
        this.state = {items: [], text: ''};
    }

    render() {
        return (
            <div>
                <h3>TODO</h3>
                <TodoList items={this.state.items} />
                <form onSubmit={this.handleSubmit}>
                    <input onChange={this.handleChange} value={this.state.text} />
                    <button>{'Add #' + (this.state.items.length + 1)}</button>
                </form>
            </div>
        );
    }

    handleChange(e) {
        this.setState({text: e.target.value});
    }

    handleSubmit(e) {
        e.preventDefault();
        var newItem = {
            text: this.props.w +''+this.props.t,
            id: Date.now()
        };
        this.setState((prevState) => ({
            items: prevState.items.concat(newItem),
            text: ''
        }));
    }

    delete(id){          // How that function knows id of item that need to delete and how to delete item?
        this.setState(this.item.id)
    }
}

class TodoList extends React.Component {
    render() {
        return (
            <ul>
                {this.props.items.map(item => (
                    <li key={item.id}>{item.text}<button onClick={this.delete.bind(this)}>Delete</button></li>
                ))}
            </ul>
        );
    }
}
