所以我们就有了createStore这个函数帮我们生成store, 然后将getState 跟 dispatch 方法export出去。...function createStore(state, stateChanger) { const getState = () => state; const dispatch = (action...) => stateChanger(state, action) return {getState, dispatch} } createStore 接受两个参数，一个是表示app的 state。..., dispatch, subscribe} } 我们就可以这样使用 store.subscribe(() => renderApp(store.getState())) 由此可以看出，dispatch...())) // 首次渲染页面 renderApp(store.getState()) // 后面可以随意 dispatch 了，页面自动更新 store.dispatch(...)

return state } } let store = createStore(counterReducer) store.subscribe(() => console.log(store.getState...3: getState：获取当前的状态。 4: replaceReducer：替换reducer。...上面是redux-logger中间件的简单实现，常用的中间件还有redux-thunk，核心代码如下： const thunk = ({ dispatch, getState }) => next =>...action => { if (typeof action === 'function') { return action(dispatch, getState) } return...next(action) } redux-thunk的逻辑也很简单，通过对store解构获取dispatch和getState函数，如果action是函数则调用action，否则调用next(action

redux的主要API集中在createStore函数返回值中，以下这个迷你的redux只简单实现createStore、dispatch、subscribe、getState方法，如下： const...currentState = initialState; } let currentReducer = reducer; let listeners = []; return { getState...store.subscribe(function() { console.log('before2') }); store.dispatch({ type:'ADD' }); console.log(store.getState...()); store.dispatch({ type: 'ADD' }); console.log(store.getState()); store.dispatch({ type: 'DEL'...}); console.log(store.getState()); 运行结果： ?
store对象对外暴露了dispatch、getState、subscribe方法 store对象通过getState() 获取内部状态 initialState为 store 的初始状态，如果不传则为...You may then * call `getState()` to read the current state tree inside the callback....可以先看伪代码感受下，最终 store.getState() 返回的state，大概会是这么个样子{todos: xx, filter: xx}。...()); // state is: 读书,阅读,睡觉 actions.addTodo('看电影'); console.log('state is: ' + store.getState()); /...middlleware (redux-thunk),可以看到,chain的每个元素为如下形式的function 并且, 传入的 store.getState 为原始的 store.getState
main(String[] args) { Context context = new Context(new TreatGirlfriend()); context.getState...();//对待女朋友的状态 Context context1 = new Context(new TreatMother()); context1.getState();...} } abstract class SelfStrategy{ public abstract void getState(); //对待人地状态，对待不同人有不同实现 } class Context...() { strategy.getState(); } } class TreatGirlfriend extends SelfStrategy{ @Override...extends SelfStrategy{ @Override public void getState() { System.out.println("对待母亲地状态
