我想创建一个简单的表单,其中包含一个电子邮件地址,然后将其添加到我们的数据库中。我使用了React Forms,因为它有利于整个开发过程并减少了时间。
但是,当我尝试POST我的表单时,我收到此错误:未捕获错误:您必须传递handleSubmit()一个onSubmit函数或传递onSubmit作为prop
这是我的 AddUserForm.js :
import React from 'react'
import { Field, reduxForm } from 'redux-form'
const AddUserForm = ({ handleSubmit }) => {
return (
<form onSubmit={handleSubmit}>
<div>
<Field name="email" component="input" type="email" />
</div>
<button type="submit">Bjud in</button>
</form>
)
}
export default reduxForm({
form: 'addUser'
})(AddUserForm)
这是我的 addUserAction :
import axios from 'axios'
import settings from '../settings'
axios.defaults.baseURL = settings.hostname
export const addUser = email => {
return dispatch => {
return axios.post('/invite', { email: email }).then(response => {
console.log(response)
})
}
}
这是我的 AddUserContainer.js:
import React, { Component } from 'react'
import { addUser } from '../../actions/addUserAction'
import AddUserForm from './Views/AddUserForm'
import { connect } from 'react-redux'
class AddUserContainer extends Component {
submit(values) {
console.log(values)
this.props.addUser(values)
}
render() {
return (
<div>
<h1>Bjud in användare</h1>
<AddUserForm onSubmit={this.submit.bind(this)} />
</div>
)
}
}
function mapStateToProps(state) {
return { user: state.user }
}
export default connect(mapStateToProps, { addUser })(AddUserContainer)
感谢阅读!
答案 0 :(得分:2)
onSubmit
未定义,因为它未声明。按照路径:
注意:values
变量包含字段数据,在您的情况下,它会保存键入的电子邮件。
import React from 'react';
import { Field, reduxForm } from 'redux-form';
import { connect } from 'react-redux';
const AddUserForm = ({ handleSubmit }) => {
return (
<form onSubmit={handleSubmit}>
<div>
<Field name="email" component="input" type="email" />
</div>
<button type="submit">Bjud in</button>
</form>
)
}
const onSubmit = (values, dispatch) => {
dispatch( // your submit action // );
};
export default connect()(reduxForm({
form: 'addUser',
onSubmit,
})(AddUserForm));
