const mapStateToProps = (state) => ({
todos: getVisibleTodos(state.todos, state.visibilityFilter)
})官方案例TODOS中 state.todos state.visibilityFilter是怎么來的？const visibilityFilter = (state = 'SHOW_ALL', action) => { switch (action.type) { case 'SET_VISIBILITY_FILTER':
return action.filter default: return state
}
}export default visibilityFilter是reducer里的這個方法嗎const todoApp = combineReducers({
todos,
visibilityFilter
})然后state.visibilityFilter可以直接取到state值show_all?
