单击时不显示模态(反应)

Question

我正在尝试获取一个模态来运行我试图镜像的模态在这里可用。

https://codesandbox.io/s/n9zn3n43o0

模态的按钮正在显示，但模态本身不会显示。 这是我对此函数的确切代码。

class App extends React.Component {
constructor(props) {
console.log("Props - ", props);
super(props);
this.state = {
modalVisible: false
};
this.openModal = this.openModal.bind(this);
}
openModal() {
console.log("Open modal called ", this.state.modalVisible);
const modalVisible = !this.state.modalVisible;
this.setState({
modalVisible
});
}
render() {
let styles = this.state.modalVisible
? { display: "block" }
: { display: "none" };
return (
<div className="App">
<h1>Hello CodeSandbox</h1>
<h2>Start editing to see some magic happen!</h2>
<button
type="button"
onClick={this.openModal}
className="btn btn-info btn-lg"
>
Open Modal
</button>
<div
id="myModal"
className="modal fade in"
role="dialog"
style={styles}
>
<div className="modal-dialog">
<div className="modal-content">
<div className="modal-header">
<button
type="button"
onClick={this.openModal}
className="close"
>
&times;
</button>
<h4 className="modal-title">Modal Header</h4>
</div>
<div className="modal-body">
<p>Some text in the modal.</p>
</div>
<div className="modal-footer">
<button
onClick={this.openModal}
type="button"
className="btn btn-default"
>
Close
</button>
</div>
</div>
</div>
</div>
</div>
);
}
}

这是整个页面的代码

this.state = { AccountDetails: [] };
}
// sets the questions form sql into state for questions
getItems() {
var user = window.localStorage.getItem("User");
if (user) {
fetch(`/profile-work-station-detailss/${user}`)
.then(recordset => recordset.json())
.then(results => {
this.setState({ AccountDetails: results.recordset });
});
} else {
alert("user not  set");
}
}
//when the component mounts make the sql questions the

this.setState({

}
render() {

}
}

我已经尝试了多个示例，但此问题仍然存在。 我错过了什么吗？ 任何帮助非常感谢。

希望这对某人有所帮助，这是我使用的代码，它工作正常。

class Header extends React.Component {
constructor(props) {
super(props);
this.handleClose = this.handleClose.bind(this);
this.handleShow = this.handleShow.bind(this);
this.state = {
show: false
};
}
handleClose() {
this.setState({
show: false
});
}
handleShow() {
this.setState({
show: true
});
}
render() {
// console.log(this.state);
return (
<div className="header-container">
<Button onClick={this.handleShow}>LOGIN</Button>
<Modal show={this.state.show} onHide={this.handleClose}>
<Modal.Header closeButton>
<Modal.Title>Modal Header</Modal.Title>
</Modal.Header>
<Modal.Body>Modal Body</Modal.Body>
</Modal>
</div>
);
}
}
