开发环境:Windows 8,node v8.9.1,npm 5.5.1,WebStorm 2017.2.2
import React from 'react';
import {HashRouter, Route, NavLink, Redirect} from 'react-router-dom';
import Redux1 from './redux1/Index'
import Redux2 from './redux2/Index'
const Index = ({match}) =>
<HashRouter>
<div>
<div className="nav">
<NavLink to="/Redux/Redux1" activeClassName="selected">Redux1</NavLink>
<NavLink to="/Redux/Redux2" activeClassName="selected">Redux2</NavLink>
</div>
<Route exact path={`${match.url}`}
render={() => (<Redirect to={`${match.url}/Redux1`}/>)}/>
<Route path={`${match.url}/Redux1`} component={Redux1}/>
<Route path={`${match.url}/Redux2`} component={Redux2}/>
</div>
</HashRouter>
;
export default Index;
2、编写业务代码 redux2 -> Index.jsx
import React from 'react';
import {createStore} from 'redux';
import {Provider, connect} from 'react-redux';
import reducer from './reducer'
const store = createStore(reducer);
class Index extends React.Component {
render() {
return (
<div className="todoList">
<input type="text" ref="todoInput"/>
<button onClick={() => this.props.dispatch({type: 'ADD', title: this.refs['todoInput'].value})}>添加
</button>
{
this.props.storeState.list.map(data => <li key={data.id}>{data.title}</li>)
}
</div>
);
}
}
const mapStateToProps = state => ({storeState: state});
const Main = connect(
mapStateToProps
)(Index);
export default () =>
<Provider store={store}>
<Main/>
</Provider>
;
3.修改reducer.js
export default (state = {
list: []
}, action)=> {
switch (action.type) {
/*业务模型判断*/
case 'ADD':
if (!action.title) {
alert('不能为空');
return state;
}
let list = state.list;
list.push({id: state.list.length + 1, title: action.title, status: 1});
return {list};
default:
return state;
}
};
