javascript - Reactjs-Redux : Clearing forms without redux-form

Question

我是 redux 新手，我正在制作一个不使用 redux-form 的组件。有没有办法在不使用 redux-form 的情况下清除任何表单？例如，我输入 abcd 并单击提交按钮，如果提交成功，输入字段应该被清除/清理。

这是我的组件

import React, { Component } from 'react'
import { connect } from 'react-redux'
import {  saveSomething } from '../../actions'

class InputSomething extends Component {

state={
	inputValue: ""
}

handleInput = (key, e) => {
this.setState({[key]: e.target.value})
}

save(){
	this.props.saveSomething()
}

render(){
  return(
    <input type="text" value={this.state.inputValue} onChange={this.handleInput.bind(this, 'inputValue')}/>
    <input type="submit" onClick={this.save}/>
	)}
}

const mapStateToProps = state => {
  return {
    saveRetun: state.saveReturn
  }
}

export default connect(mapStateToProps, { saveSomething })(InputSomething)

这是我的行动

import axios from 'axios'
import {
  SAVE_SOMETHING,
  SAVE_SOMETHING_SUCCESS,
  SAVE_SOMETHING_FAILED
} from './types'



export const saveSomething = () =>{
  var url = '/someurlhere'
  return(dispatch)=>{
    dispatch({type:SAVE_SOMETHING})
    axios.post(url)
    .then((res)=>{
      dispatch({
        type:SAVE_SOMETHING_SUCCESS, payload:res.data
      })
    })
    .catch((error)=>{
        dispatch({
            type:SAVE_SOMETHING_FAILED, payload:error
          })
      })
  }
}

这是我的 reducer

import {
  SAVE_SOMETHING,
  SAVE_SOMETHING_SUCCESS,
  SAVE_SOMETHING_FAILED
} from '../actions/types'

const INITIAL_STATE = { loading: true, data : [], error: '' , success: false };

export default (state = INITIAL_STATE, action) => {
  switch (action.type){
    case SAVE_SOMETHING:
      return {...state, loading: true}
    case SAVE_SOMETHING_SUCCESS:
      return {...state, loading: false, data: action.payload, success: true}
    case SAVE_SOMETHING_FAILED:
      return {...state, loading: false, error: action.payload, success: false}
    default:
      return state
  }
};

您只需使用初始数据重新初始化组件即可成功。

export default (state = INITIAL_STATE, action) => {
  switch (action.type){
    case SAVE_SOMETHING:
      return {...state, loading: true}
    case SAVE_SOMETHING_SUCCESS:

      // reset to initial data

      return {data: [], loading: false, success: true}

    case SAVE_SOMETHING_FAILED:
      return {...state, loading: false, error: action.payload, success: false}
    default:
      return state
  }
};
