MpxUsewatchOnce
watch 仅执行一次
用法
回调功能触发一次后，watch将自动停止。
ts
import { watchOnce } from '@mpxjs/mpxuse-core'
watchOnce(source, () => {
// triggers only once
console.log('source changed!')
})
import { watchOnce } from '@mpxjs/mpxuse-core'
watchOnce(source, () => {
// triggers only once
console.log('source changed!')
})
类型声明
typescript
export declare function watchOnce<
T extends Readonly<WatchSource<unknown>[]>,
Immediate extends Readonly<boolean> = false
>(
source: [...T],
cb: WatchCallback<MapSources<T>, MapOldSources<T, Immediate>>,
options?: WatchOptions
): void

Immediate extends Readonly<boolean> = false
