[英]React Hook useEffect has a missing dependency: 'props'
[英]React Hook useEffect has a missing dependency when passing props using React Hook
所以我嘗試使用 Effect 從 redux 傳遞組件,這是我的代碼:
const initState = {
newAttribs: { ...props.state.Auth },
};
const [userList, setUserList] = useState(initState);
useEffect(() => {
setUserList({ ...userList, newAttribs: { ...props.state.Auth } });
}, [props.state.Auth]);
console.log("userList now", userList);
但它一直在控制台中發出這樣的警告:
WARNING in [eslint]
src\pages\Login.jsx
Line 15:6: React Hook useEffect has a missing dependency: 'userList'. Either include it or remove the dependency array. You can also do a functional update 'setUserList(u => ...)' if you only need 'userList' in the 'setUserList' call react-hooks/exhaustive-deps
有人可以向我解釋我在這里做錯了什么....
您的效果掛鈎取決於userList
但它不包含在依賴項數組中。 一種有用的替代方法是使用 state 設置器的回調 function 形式:
setUserList(userList => (
{ ...userList, newAttribs: { ...props.state.Auth }) }
);
