我正在尝试第一次使用redux-form。我可以呈现表单,但无法处理提交。虽然我最终希望将数据发送到服务器,但此时,我只是在尝试控制台记录表单字段值。我收到错误消息:Error: You must either pass handleSubmit() an onSubmit function or pass onSubmit as a prop
这是我的Profile.jsx文件
import React, {Component} from 'react';
import {connect} from 'react-redux';
import {withAuth} from 'react-devise';
import { Field, reduxForm } from 'redux-form';
class Profile extends Component {
handleSubmit(data) {
console.log('Submission received!', data);
}
render() {
const { handleSubmit } = this.props;
return (
<form onSubmit={handleSubmit}>
<div>
<label htmlFor="firstName">First Name</label>
<Field name="firstName" component="input" type="text"/>
</div>
<div>
<label htmlFor="lastName">Last Name</label>
<Field name="lastName" component="input" type="text"/>
</div>
<div>
<label htmlFor="email">Email</label>
<Field name="email" component="input" type="email"/>
</div>
<button type="submit">Submit</button>
</form>
);
}
}
// Decorate the form component
Profile = reduxForm({
form: 'profile' // a unique name for this form
})(Profile);
const mapStateToProps = state => {
return {
currentUser: state.currentUser
};
};
export default connect(mapStateToProps)(withAuth(Profile));
如何处理提交的值,最终将它们发送到我的API?
最佳答案
Redux-Form使用handleSubmit
属性装饰您的组件。根据文档,它是:
因此,如果您的组件没有onSubmit
属性,则必须“手动”将提交处理程序传递给handleSubmit
函数。请尝试以下方法:
<form onSubmit={this.props.handleSubmit(this.handleSubmit.bind(this))}>
请不要将
handleSubmit
方法与从Redux-Form传递的具有相同名称的prop混淆。
