Javascript （Redux Form）必须传递handleSubmit（）一个onSubmit函数或作为prop传递onSubmit

我是一个超级React redux初学者，刚刚开始我的第一个个人项目。我正在尝试使用Redex表单构建提交表单，但我遇到了第一个无法克服的错误。。。这是我唯一有问题的地方

如果您想查看整个项目文件，请参阅my github

这是提交表单.js

import React, { Component } from 'react';
import { reduxForm } from 'redux-form';
import { submitForm } from '../actions/action_submit_form';
// import { Link } from 'react-router';


class SubmitForms extends Component {
   onSubmit(props) {
     this.props.submitForm(props)
       .then(() => {
          console.log("good submit");
       });
   }

  render() {
    const { fields: { gender, age, height, weight, activity }, 
    handleSubmit } = this.props;

return (
    <form onSubmit={handleSubmit(this.props.submitForm)}>
    <div className="form-group">
      <label className="control-label">Gender</label>
      <select type="gender" className="form-control" id="gender_id" name="gender_name" { ...gender }>
        <option>Male</option>
        <option>Female</option>
      </select>
    </div>
    <div className="form-group">
      <label className="control-label">Age</label>
      <input type="age" className="form-control" id="age_id" name="age_name" { ...age } />
    </div>
    <div className="form-group">
      <label className="control-label">Height</label>
      <input type="height" className="form-control" id="height_id" name="height_name" { ...height } />
    </div>
    <div className="form-group">
      <label className="control-label">Weight</label>
      <input type="weight" className="form-control" id="weight_id" name="weight_name" { ...weight } />
    </div>
    <div className="form-group">
      <label className="control-label">Activity</label>
      <select type="activity" className="form-control" id="activity_id" name="activity_name" { ...activity }>
        <option>1</option>
        <option>2</option>
        <option>3</option>
        <option>4</option>
        <option>5</option>
      </select>
    </div>

    <div className="form-group">
      <button type="submit" className="btn btn-primary">Submit</button>
    </div>
  </form>
);
}
}

export default reduxForm({
  form: 'SubmitNewForm',
  fields: ['gender', 'age', 'height', 'weight', 'activity']
}, null, { submitForm })(SubmitForms);

import axios from 'axios';

export const ADD_POST = 'ADD_POST';
const BASE_URL = 'http://138.197.166.14:8000';


export function submitForm(props) {
  console.log('action is hit:');
  const calculatedResult = axios.get(`${BASE_URL}/getcalories`);

  return {
    type: ADD_POST,
    payload: calculatedResult
  };
}

import reducerSubmitForm from './reducer_submit_form';
import { combineReducers } from 'redux';
import { reducer as formReducer } from 'redux-form';

const rootReducer = combineReducers ({
  post: reducerSubmitForm,
  form: formReducer
});

这是reducerindex.js，reducer\u submit\u form.js

import React, { Component } from 'react';
import { reduxForm } from 'redux-form';
import { submitForm } from '../actions/action_submit_form';
// import { Link } from 'react-router';


class SubmitForms extends Component {
   onSubmit(props) {
     this.props.submitForm(props)
       .then(() => {
          console.log("good submit");
       });
   }

  render() {
    const { fields: { gender, age, height, weight, activity }, 
    handleSubmit } = this.props;

return (
    <form onSubmit={handleSubmit(this.props.submitForm)}>
    <div className="form-group">
      <label className="control-label">Gender</label>
      <select type="gender" className="form-control" id="gender_id" name="gender_name" { ...gender }>
        <option>Male</option>
        <option>Female</option>
      </select>
    </div>
    <div className="form-group">
      <label className="control-label">Age</label>
      <input type="age" className="form-control" id="age_id" name="age_name" { ...age } />
    </div>
    <div className="form-group">
      <label className="control-label">Height</label>
      <input type="height" className="form-control" id="height_id" name="height_name" { ...height } />
    </div>
    <div className="form-group">
      <label className="control-label">Weight</label>
      <input type="weight" className="form-control" id="weight_id" name="weight_name" { ...weight } />
    </div>
    <div className="form-group">
      <label className="control-label">Activity</label>
      <select type="activity" className="form-control" id="activity_id" name="activity_name" { ...activity }>
        <option>1</option>
        <option>2</option>
        <option>3</option>
        <option>4</option>
        <option>5</option>
      </select>
    </div>

    <div className="form-group">
      <button type="submit" className="btn btn-primary">Submit</button>
    </div>
  </form>
);
}
}

export default reduxForm({
  form: 'SubmitNewForm',
  fields: ['gender', 'age', 'height', 'weight', 'activity']
}, null, { submitForm })(SubmitForms);

import axios from 'axios';

export const ADD_POST = 'ADD_POST';
const BASE_URL = 'http://138.197.166.14:8000';


export function submitForm(props) {
  console.log('action is hit:');
  const calculatedResult = axios.get(`${BASE_URL}/getcalories`);

  return {
    type: ADD_POST,
    payload: calculatedResult
  };
}

import reducerSubmitForm from './reducer_submit_form';
import { combineReducers } from 'redux';
import { reducer as formReducer } from 'redux-form';

const rootReducer = combineReducers ({
  post: reducerSubmitForm,
  form: formReducer
});

我认为这个错误很简单

检查SubmitForms类呈现方法中的以下行：

<form onSubmit={handleSubmit(this.props.submitForm)}>

---

根据redux表单，必须将提交函数传递给onSubmit。

应在调用

reduxForm

时设置

onSubmit

函数。submit处理程序上的标记应该只是对Redux表单为您注入的函数

handleSubmit

的引用。我同意命名有点混乱。：）

参见文档中的示例：

我做了console.log（handleSubmit（this.props.submitForm））；chrome浏览器中的控制台。那是正确的地方吗？？无论如何，我得到了错误“VM5884:1未捕获引用错误：未定义handleSubmit”。@JongHunLee这就是问题所在。您正在将一个未定义的值传递给“onSubmit”prop，它应该是一个函数。我在你的代码中没有看到任何关于“handleSubmit”的引用，所以我假设这是你可能复制粘贴和编辑的示例的剩余部分？不是复制粘贴，而是我参考了我从中学习的课程。这是我提到的课程项目，谢谢你的回答。在看了你给出的链接之后，我将尝试你的解决方案并告诉你结果。谢谢

ContactForm = reduxForm({
  // a unique name for the form
  form: 'contact',
  // you can define your custom onSubmit here!
  onSubmit: ...
})(ContactForm)
