如何在react函数中使用reactstrap制作Modal

Question

我正在尝试使函数成为模态，但显示以下错误

  错误：第25行：预期分配或函数调用，而不是   看到一个表达式no-unused-expressions

代码

class Task extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      modal: false
    };
    this.toggle = this.toggle.bind(this);
    this.v_toggle = this.v_toggle.bind(this);
  }

  toggle() {
    this.setState({
      modal: !this.state.modal
    });
  }

  v_toggle(){
    console.log("hi, i am here");
    <div>
      <Modal isOpen={this.state.modal} toggle={this.v_toggle} className={this.props.className}>
        <ModalHeader toggle={this.v_toggle}>Modal title</ModalHeader>
        <ModalBody>
