如何从文本输入更新redux的状态?

我试图做一个非常简单的" Hello World"带有文字输入。当有人输入文字输入时,它应该更新我的商店" searchTerm"值。

我无法弄清楚这些事情:  1.如何获取输入的值并将其传递给它" onChange"处理程序?  2."搜索"动作似乎被正确调用,但我的reducer函数从未使用过(没有console.log)。

SearchForm.js (组件)

import React, {Component, PropTypes} from 'react';
import {bindActionCreators} from 'redux';
import {connect} from 'react-redux';
import {search} from 'redux/modules/search-term';

@connect(
  null,
  dispatch => bindActionCreators({ search }, dispatch)
)

export default class SearchForm extends Component {
  static propTypes = {
    search: PropTypes.func.isRequired,
  }

  render() {
    return (
      <input type="text" placeholder="Search" onChange={search} />
    );
  }
}

search-term.js (动作与减速机)

const SEARCH = 'redux-example/repo-filter/SEARCH';

const initialState = {
  searchTerm: null
};

export default function reducer(state = initialState, action = {}) {
  console.log("reducing");

  switch (action.type) {
    case SEARCH:
      return {
        searchTerm: action.term
      };
    default:
      return state;
  }
}

export function search(term) {
  return {
    type: SEARCH,
    term
  };
}

reducer.js

import { combineReducers } from 'redux';
import multireducer from 'multireducer';
import { routerStateReducer } from 'redux-router';

import search from './search-term';

export default combineReducers({
  router: routerStateReducer,
  search
});

将动作创建者绑定到更改事件时,您应该使用this.props.search

<input type="text" placeholder="Search" onChange={(event) => this.props.search(event.target.value)} />
