即使依赖性没有更改,USEMEMO函数即使执行
我有一个父组件,可以在React查询中每次呈现数据更改。它使用的是传递应该渲染一些卡的数据的子组件。
在子组件中,我使用usememo()函数来确保它是否接收到与以前相同的数据,它不会执行所有卡的渲染。
这是父零件
export const VerticalCardsList = (props : VerticalCardsProps) => {
const VerticalCards = useMemo(() => {
console.log('Executing the useMemo function')
}, [props.verticalCardsData])
return VerticalCards }
以这样的方式调用此的子部分
<VerticalCardsList verticalCardsData={props?.cardsResponse?.data?} />
I have a parent component which renders everytime data in the react query changes. It is using a child component to which it passes data which should render some cards.
Inside the child component, I used the useMemo() function to make sure if it receives the same data as previously it wouldnt execute the rendering of all the cards.
This is the child component
export const VerticalCardsList = (props : VerticalCardsProps) => {
const VerticalCards = useMemo(() => {
console.log('Executing the useMemo function')
}, [props.verticalCardsData])
return VerticalCards }
The parent component calls this in a way like this
<VerticalCardsList verticalCardsData={props?.cardsResponse?.data?} />
