我的应用程序在我开始结合我的Redux reducer之前工作正常。但是当我结合起来，initialState和reducer键会混合起来。
function flash(state = [],action) {
switch (action.type) {
case FLASH_MESSAGE_UPDATED:
return _.extend({},state,{ flash: action.flash })
default:
return state
}
}
function events(state = [],action) {
switch (action.type) {
case EVENTS_UPDATED:
return _.extend({},{ events: action.pathway_events })
default:
return state
}
}
export default combineReducers({
events,flash
})
在initialState参数中发现意外的键“一”，“二”，传递给createStore。期望找到一个已知的reducer键，而不是“事件”，“闪存”。意外的键将被忽略。
我的初始状态在redux-thunk的帮助下传入。
import { createStore,applyMiddleware } from 'redux';
import thunk from 'redux-thunk';
import reducer from '../../reducers/event'
let initialState = {
one: globalData.one,two: globalData.two,events: globalData.events,flash: globalData.flash
}
let createStoreWithMiddleware = applyMiddleware(thunk)(createStore)
let reduxStore = createStoreWithMiddleware(reducer,initialState);
React.render(
<Provider store={reduxStore}>
<EventListContainer />
</Provider>,$('.events')[0]
)
如何正确地组合reducer？
我想你只需要添加reducers的附加键，例如
原文链接：https://www.f2er.com/react/301401.htmlfunction one(state = {},action) {
switch (action.type) {
case ONE_UPDATED:
return action.one
default:
return state
}
}
从the docs：
If you produced reducer with combineReducers,this must be a plain object with the same shape as the keys passed to it. Otherwise,you are free to pass anything that your reducer can understand.
如果您不需要处理与一个或两个相关的任何操作，只需将它们初次拉出，这可能就如此简单
export default combineReducers({
events,flash,one: (state = {}) => state,two: (state = {}) => state
})
