useLastChanged

Demo

最后更改: 5 minutes ago (1730363784697)

使用方法

import { useLastChanged } from '@vueuse/core'
import { nextTick } from 'vue-demi'

const a = ref(0)
const lastChanged = useLastChanged(a)

a.value = 1

await nextTick()

console.log(lastChanged.value) // 1704709379457

默认情况下，更改将在下一个tick上记录（使用 watch() 并且 flush: 'post'）。如果你想立即记录更改，请将 flush: 'sync' 作为第二个参数传递。

import { useLastChanged } from '@vueuse/core'

const a = ref(0)
const lastChanged = useLastChanged(a, { flush: 'sync' })

a.value = 1

console.log(lastChanged.value) // 1704709379457

类型声明

export interface UseLastChangedOptions<
  Immediate extends boolean,
  InitialValue extends number | null | undefined = undefined,
> extends WatchOptions<Immediate> {
  initialValue?: InitialValue
}
