我站在一个棘手的情况。减速器未点火
我我的减速器rhythmReducer.js如下:
import {TOGGLE_NOTE_VALUE} from '../constants/actionTypes';
import objectAssign from 'object-assign';
import initialState from './initialState';
export default function rhythmReducer(state = initialState.rhythm, action) {
let newState = objectAssign({}, state);
console.log("---RhythmReducer");
console.log(action.type);
switch (action.type) {
case TOGGLE_NOTE_VALUE:
console.log("TOGGLE_NOTE_VALUE");
return newState;
default:
return newState;
}
}
组件使用它是RhythmContainer.js:
import React, {PropTypes} from 'react';
import {connect} from 'react-redux';
import {bindActionCreators} from 'redux';
import * as actions from '../actions/rhythmActions';
import {Meter} from './Meter';
export const RhythmContainer = (props) => {
let rows = [];
for (let i=0; i < props.rhythm.meters.length; i++) {
rows.push(<Meter key={i} actions={actions} rhythm= {props.rhythm.meters[i]}/>);
}
const handleClick =() => {
return props.store.dispatch(actions.toggleNoteValue);
};
return (
<div onClick={handleClick}>
This will be a 4/4 rhythm
{rows}
</div>
);
};
RhythmContainer.propTypes = {
rhythm: PropTypes.object.isRequired,
store: PropTypes.object.isRequired,
};
function mapStateToProps(state) {
return {
rhythm: state.rhythm,
};
}
function mapDispatchToProps(dispatch) {
return {
actions: bindActionCreators(actions, dispatch)
};
}
export default connect(
mapStateToProps,
mapDispatchToProps
)(RhythmContainer);
我的动作在rhythmActions.js
import * as types from '../constants/actionTypes';
export function toggleNoteValue() {
console.log("toggleNoteValue");
return {type: types.TOGGLE_NOTE_VALUE};
}
定义即使减速运行,当页面正在初始化,我不能得到它,当我点击DIV运行。 toggleNoteValue()正在启动,但它永远不会在实际的Reducer中执行。 有什么帮助吗?

您没有将'Note'组件与redux连接起来。 –
另外,您没有通过dispatch()发送操作。 – macbem
我传播的功能下降到元素,但我有3包装组件,这将导致帖子不可读。你通过派遣@macbem表达什么意思?我有函数mapDispatchToProps(dispatch){ return { actions:bindActionCreators(actions,dispatch) }; }在我的主要组件 –
