【问题描述】:
我在尝试在窗口上执行调度操作时遇到此错误:“未捕获的 TypeError:调度不是函数”。
我仔细检查了语法。
Uncaught TypeError: dispatch is not a function

export const fetchAllSpots = () => dispatch => (
APIUtil.fetchAllSpots().then(spots =>
dispatch(receiveAllSpots(spots)))
);
const receiveAllSpots = payload => ({
type: RECEIVE_ALL_SPOTS,
payload
});
window.fetchAllSpots = fetchAllSpots();
【问题讨论】:
-
这里是util调用函数:export const fetchAllSpots = () => ($.ajax({ method: 'GET', url: '/api/spots', }) );跨度>
-
你还没有将 dispatch 定义为函数
-
您能详细说明一下吗?谢谢!
-
您是否将 redux-thunk 作为中间件连接到您的 redux 存储?
