React.js-Redux：清除表单而不使用Redux-form

Question

我是redux的新手，我在不使用redux-form的情况下制作组件。 有没有一种方法可以不使用redux-form来清除任何表单？ 例如，我输入了abcd并单击了提交按钮，如果提交成功，则应清除/清除输入字段。

这是我的组成部分

 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 }) }) } } 

这是我的减速器

 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 } };

Answer 1

您只需要使用成功的初始数据来重新初始化组件。

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
  }
};

Answer 2

save(){
this.props.saveSomething().then(this.setState({inputValue:''}))
}

上面的代码会将状态设置为空白。

save(){
this.props.saveSomething()
 .then(this.setState({inputValue:''}), this.forceUpdate())
}
