我在 react 项目中使用 bootstrap 3。在我的项目中,我创建了一个显示模态div的组件。我将在不同的父组件中使用此组件。模态在延时后显示。模态显示良好,但不会消除。关闭按钮也不起作用。
父组件
import React, { Component } from 'react';
import Timer from './timer';
class Parent extends Component {
render() {
return (
<div>
<Timer />
</div>
); }
}
export default Parent;
子组件
import React, { Component } from 'react';
class Timer extends Component {
constructor(props){
super(props);
this.state = {
fin: false
}
}
componentDidMount(){
this.myInterval = setInterval(() => {
this.setState({fin: true})
}, 10000);
}
render() {
const {fin} = this.state;
if(fin){
return (
<div className="modal show">
<div className="modal-dialog modal-dialog-centered" role="document">
<div className="modal-content">
<div className="modal-header">
<h5 className="modal-title" id="exampleModalLongTitle">Modal
title</h5>
<button type="button" name="test" className="close" onClick={this.handleClose} data-dismiss="modal"
aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div className="modal-body">
...
</div>
<div className="modal-footer">
<button type="button" className="btn btn-secondary" data-
dismiss="modal">Close</button>
<button type="button" className="btn btn-primary">Save
changes</button>
</div>
</div>
</div>
</div>
)
} else {
return (
<div>
Child counting...
</div>
)
}
}
}
export default Timer;
