gfs-react-redux-twoway-binding
数据双向绑定,在React Component中直接改变redux store中数据对象值,达到重新渲染页面的目的,减少编写更多的action;使用时请注意store数据对象必须是immutable类型且次组件是一个装饰类(decorator)
安装
npm install gfs-react-redux-twoway-binding
依赖
immutable
使用
1. createReducer
创建一个redux store;
import { createReducer } from 'gfs-react-redux-twoway-binding';
import Immutable from 'immutable';
const initialState = Immutable.fromJS({
name:'init'
});
export const test = createReducer('test',initialState, {
['QUERY']: (data, action) => {
return data.merge(Immutable.fromJS(action.data));
}
});
2. setStore
组件与具体的store建立关系;
import {bindingMixin} from 'gfs-react-redux-twoway-binding';
//用次组件装饰下面的类
@bindingMixin
export default class TestWebContainer extends Component {
constructor(props) {
super(props);
//关联store
this.setBinding('test');
}
}
3. binding
数据双向绑定,使用this.binding
方法与具体字段绑定,表单元素发生改变时将直接会改变store中的值;
render() {
return (
<div>
<input type="text" valueLink={this.binding('name') } />
{this.props.test.get('name') }
</div>
);
}
Manual Change Functions
帮助用户快速根据reducer路径更改store值,避免写更多的action。
- 手动根据路径改变reducer的值:
this.manualChange('name', 'john');
this.manualChange('name', function(age){
return ++age;
});
