useIsFetching
useIsFetching 是一个可选的钩子，它返回你的应用程序正在后台加载或获取的查询的数量（对于应用程序范围的加载指示器很有用）。
tsx
import { useIsFetching } from '@tanstack/solid-query'
// How many queries are fetching?
const isFetching = useIsFetching()
// How many queries matching the posts prefix are fetching?
const isFetchingPosts = useIsFetching({ queryKey: ['posts'] })
import { useIsFetching } from '@tanstack/solid-query'
// How many queries are fetching?
const isFetching = useIsFetching()
// How many queries matching the posts prefix are fetching?
const isFetchingPosts = useIsFetching({ queryKey: ['posts'] })
选项
- filters?: QueryFilters: 查询过滤器
- queryClient?: QueryClient
- 使用此选项可以使用自定义 QueryClient。否则，将使用最近上下文中的 QueryClient。
Returns (返回)
- isFetching: number
