我想问为什么在执行onclick事件时状态没有变化。我已经搜索了一段时间，我需要在构造函数中绑定onclick函数，但状态仍未更新。这是我的代码：

import React from 'react';

import Grid from 'react-bootstrap/lib/Grid';
import Row from 'react-bootstrap/lib/Row';
import Col from 'react-bootstrap/lib/Col';

import BoardAddModal from 'components/board/BoardAddModal.jsx';

import style from 'styles/boarditem.css';

class BoardAdd extends React.Component {

    constructor(props){
        super(props);

        this.state = {
            boardAddModalShow: false
        }

        this.openAddBoardModal = this.openAddBoardModal.bind(this);
    }
    openAddBoardModal(){
        this.setState({ boardAddModalShow: true });
// After setting a new state it still return a false value
        console.log(this.state.boardAddModalShow);

    }

    render() {

        return (
            <Col lg={3}>
                <a href="javascript:;" className={style.boardItemAdd} onClick={this.openAddBoardModal}>
                    <div className={[style.boardItemContainer,style.boardItemGray].join(' ')}>
                        Create New Board
                    </div>
                </a>



            </Col>
        )
    }
}

export default BoardAdd
