我有一个Route组件,它将基于当前url呈现一行表,问题是我无法使用放在Link组件上的onClick更新状态,URL更改了,但状态仍然相同,因此渲染的行内容仍然相同,请看以下代码:
<Route
exact
path={'/dashboard/:page'}
render={() => (
this.state.data &&
data.map((data, index) =>
<Row key={index}>
<Col md="1" xl="1">{index + 1}</Col>
<Col md="3" xl="4">{data.job_title}</Col>
<Col md="2" xl="3">{data.city}</Col>
<Col md="2" xl="2">{data.job_status}</Col>
<Col md="2" xl="2"><a href="">{data.inbox.length > 1 ? data.inbox + ' Candidates' : data.inbox + ' Candidate'}</a></Col>
</Row>
)
)}
/>
<Route
exact
path={'/dashboard'}
render={() => (
this.state.data &&
data.map((data, index) =>
<Row key={index}>
<Col md="1" xl="1">{index + 1}</Col>
<Col md="3" xl="4">{data.job_title}</Col>
<Col md="2" xl="3">{data.city}</Col>
<Col md="2" xl="2">{data.job_status}</Col>
<Col md="2" xl="2"><a href="">{data.inbox.length > 1 ? data.inbox + ' Candidates' : data.inbox + ' Candidate'}</a></Col>
</Row>
)
)}
/>
</div>
<div style={{display: 'flex', justifyContent: 'center'}}>
<Link onClick={() => {this.setState({currentPage: this.state.currentPage + 1, data: dataMock.data[this.state.currentPage + 1]})}} to="/dashboard/1">
<Button style={{margin: '20px'}}>Page + 1</Button>
</Link>
<Link onClick={() => {this.setState({currentPage: this.state.currentPage - 1, data: dataMock.data[this.state.currentPage - 1]})}} to='/dashboard/2'>
<Button style={{margin: '20px'}}>Page - 1</Button>
</Link>
</div>
问题是我如何用新状态更新状态?似乎状态没有更新,我做错了吗?我对之前找到的解决方案有点困惑,这里是链接:React to url change within component with React Router 4?
答案 0 :(得分:0)
如果这是一个好习惯,我不习惯。但是更简单的解决方法是
将click事件添加到按钮,然后在setState的回叫this.props.history.push('Route')
例如,
takeUserToPage = () => {
this.setState({currentPage: this.state.currentPage + 1, data:
dataMock.data[this.state.currentPage + 1]}, () => {
this.props.history.push('Route')
});
}
//inside your return
<Button style={{margin: '20px'}} onClick={this.takeUserToPage}>Page + 1</Button>
