react报错解决Renderedmorehooksthanthepreviousrender.

constRenderItem=(item)=>{const{children}=item;const[showChild,setShowChild]=useState(false);return(<>

{showChild&&children.length>0&&(<>//使用普通函数会报错{children.map((ele)=>(<>{RenderItem(ele)}))})});};上面的代码会报错：Renderedmorehooksthanthepreviousrender。只需将调用自身的行更改为：{children.map(ele=>}根据规范，RenderItem，R应大写
