在使用React Router V4进行一些验证后,如何移动到新页面？我有这样的事情：
export class WelcomeForm extends Component {
handleSubmit = (e) => {
e.preventDefault()
if(this.validateForm())
// send to '/life'
}
render() {
return (
<form className="WelcomeForm" onSubmit={this.handleSubmit}>
<input className="minutes" type="number" value={this.state.minutes} onChange={ (e) => this.handleChanges(e,"minutes")}/>
</form>
)
}
}
您正在使用
react-router v4,因此您需要将
withRouter与您的组件一起使用以访问历史对象的属性,然后使用history.push动态更改路由.
原文链接：https://www.f2er.com/react/300662.htmlYou can get access to the history object’s properties and the closest
‘s match via the withRouter higher-order component. withRouter
will re-render its component every time the route changes with the
same props as render props: { match,location,history }.
像这样：
import {withRouter} from 'react-router-dom';
class WelcomeForm extends Component {
handleSubmit = (e) => {
e.preventDefault()
if(this.validateForm())
this.props.history.push("/life");
}
render() {
return (
<form className="WelcomeForm" onSubmit={this.handleSubmit}>
<input className="minutes" type="number" value={this.state.minutes} onChange={ (e) => this.handleChanges(e,"minutes")}/>
</form>
)
}
}
export default withRouter(WelcomeForm);
