Question

我正在尝试在我的反应登录页面中使用简单的redux表单，但是当我在我的电子邮件和密码字段中尝试控制台输出值时，它们总是返回未定义。

这是我的 signin.js

import React, {Component} from 'react';
import { reduxForm } from 'redux-form';

class Signin extends Component {
  handleFormSubmit({ email, password }){
    console.log(email,password);
    console.log(this.props.email);
  }

  render(){
    const {  fields: { email, password }, handleSubmit} = this.props;

    return(
        <form onSubmit={handleSubmit(this.handleFormSubmit.bind(this))} >
            <fieldset className="form-group" >
             <label>Email:</label>
             <input {...email} className="form-control" component="input" />
             {console.log(email)}
            </fieldset>
            <fieldset className="form-group" >
             <label>password:</label>
             <input {...password} className="form-control"  />
            </fieldset>
            <button action="submit" className="btn btn-primary"> sign in</button>
        </form>
       );
    }
}

export default reduxForm({
    form: 'signin',
    fields: ['email','password']
})(Signin);

这是我在中的 index.js

import { combineReducers } from 'redux';
import { reducer as form } from 'redux-form';

const rootReducer = combineReducers({
  form
});

export default rootReducer;

这是我的 package.json

  "name": "redux-simple-starter",
  "version": "1.0.0",

    "react-router": "^2.0.1",
    "redux": "^3.0.4",
    "redux-form": "^7.3.0"
  }
}

我已经完成了所有的搜索，但仍然无法找到解决这个奇怪问题的方法。

我的输入值总是返回undefined。

Answer 1

我还没有使用FieldSet，但你必须为redux-form定义每个字段的名称。我使用了具有name属性的Field组件。使用FieldSet，在我看来，您必须使用model属性来定义redux-form的标识符。

redux表单无法存储输入值并始终返回undefined
