我想向你寻求帮助,如何消除这些错误标记。请直接给出一个示例,谢谢尝试使用效果添加以下内容:
useEffect(() => {
getReviewRatingDetail();
getReviewRating();
}, [productId])
或者整体函数ReviewProductDetail use use Callback()请详细解释您尝试了什么以及问题的具体原因。我想消除上图中的错误通知,我该怎么做?@PutraIrawan但您尝试了什么?这是因为您的代码在卸载状态变量后正在调用状态变量。您是否调查了发生这种情况的原因/方式?您的
useffect
hook是否返回清理函数?
useEffect(() => {
getReviewRatingDetail();
getReviewRating();
}, [productId])
