React :超过最大更新深度
React :超过最大更新深度
提问于 2021-04-17 18:49:04
还有我的react项目，现在我正在学习钩子，也许我有一个关于‘无限循环’的问题(超过了最大更新深度)，我不知道如何处理这个问题。我有redux来处理状态。我使用useEffect，因为当我点击一个div时，它正在显示，或者正在做我想做的事情，总是晚一步
function OffersWhatTypeOfWebsiteComponent(props) {
const dispatch = useDispatch()
const [active, setActive] = useState(1)
const [typeWebSite, setTypeWebSite] = useState('withCMS')
const updateTypeWebSite = () => {
dispatch({
type: "TYPE_WEBSITE",
payload: typeWebSite
})
}
useEffect(() => {
updateTypeWebSite();
}, [updateTypeWebSite()]);
const renderElements = (props) => {
switch (active) {
case 1 :
return (
<>
<OffersChooseYourPackageCMSComponent
/>
</>
);
break
case 2 :
return (
<>
<OffersChooseYourPackageLikeAProComponent/>
</>
)
default:
return 'error'
}
}
return (
<div>
<OffersTitleCardComponent
titleNumber='2'
titleSection='What type of Website'
/>
<div className='chooseYourProject'>
<OffersCardsWithCheckComponent
titleCard='With CMS'
subtitleCard='xxxx'
active={active === 1 ? 'listing-active' : 'listing'}
onClick={() => {
setActive(1);
setTypeWebSite('withCMS');
updateTypeWebSite()
}}
/>
<OffersCardsWithCheckComponent
titleCard='Like a pro'
subtitleCard='xxx'
active={active === 2 ? 'listing-active' : 'listing'}
onClick={() => {
setActive(2);
setTypeWebSite('like a pro');
updateTypeWebSite()
}}
/>
</div>
{
renderElements({})
}
</div>
);
}
export default OffersWhatTypeOfWebsiteComponent;这是子组件：
function OffersChooseYourPackageCMSComponent(props) {
const dispatch = useDispatch()
const [active, setActive] = useState(1)
const [packageWebSite, setPackageWebSite] = useState('Shopify')
const [pricePackageWebSite, setPricePackageWebSite] = useState(300)
const updatePackageWebSite = () => {
dispatch({
type: "PACKAGE_WEBSITE",
payload: {packageWebSite, pricePackageWebSite}
})
}
useEffect(() => {
updatePackageWebSite();
}, [updatePackageWebSite()]);
const renderElements = () => {
switch (active) {
case 1 :
return (
<>
<OffersNumbersOfProductsComponent/>
</>
);
break
case 2 :
return (
<>
<OffersNumbersOfPagesComponent/>
<OffersWoocommerceComponent/>
</>
);
break
default :
return 'error'
}
}
return (
<div>
<OffersTitleCardComponent
titleNumber='3'
titleSection='Choose your package'
/>
<div className="shopify">
<OffersCardsWithCheckComponent
onClick={() => {
setActive(1);
setPackageWebSite('Shopify');
setPricePackageWebSite(300);
updatePackageWebSite()
}}
active={active === 1 ? "listing-active" : "listing"}
titleCard='Shopify'
subtitleCard='xxx'
pricePackage='$54349'
detailPrice='(1 landing page + up to 5 products)'
/>
<OffersCardsWithCheckComponent
onClick={() => {
setActive(2);
setPackageWebSite('WordPress');
setPricePackageWebSite(900);
updatePackageWebSite()
}}
active={active === 2 ? "listing-active" : "listing"}
titleCard='WordPress'
subtitleCard='xxxx'
pricePackage='$23349'
detailPrice='(1 landing page)'
/>
</div>
{renderElements()}
</div>
);
}
export default OffersChooseYourPackageCMSComponent;也请不要犹豫地告诉我一些好的做法，如果需要的话，我也应该安排什么。
谢谢你的帮忙

您也应该将其复制到您的子组件中
const updateTypeWebSite = useCallback(() => {
dispatch({
type: "TYPE_WEBSITE",
payload: typeWebSite
})
}, [typeWebSite])
useEffect(() => updateTypeWebSite(), [updateTypeWebSite]);在reactjs上阅读this文档

找到了有效的解决方案，不知道这是否是最好的解决方案：
const [typeWebSite, setTypeWebSite] = useState('withCMS')
const updateTypeWebSite = () => {
dispatch({
type: "TYPE_WEBSITE",
payload: typeWebSite
})
}
useEffect(() => {
updateTypeWebSite()
},[typeWebSite,setTypeWebSite]);页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
