MpxUsewatchPausable
可暂停的 watch
用法
正常使用watch，但返回额外的pause和resume函数进行控制。
ts
import { watchPausable } from '@mpxjs/mpxuse-core'
import { nextTick, ref } from 'vue'
const source = ref('foo')
const { stop, pause, resume } = watchPausable(
source,
v => console.log(`Changed to ${v}!`),
)
source.value = 'bar'
await nextTick() // Changed to bar!
pause()
source.value = 'foobar'
await nextTick() // (nothing happend)
resume()
source.value = 'hello'
await nextTick() // Changed to hello!
import { watchPausable } from '@mpxjs/mpxuse-core'
import { nextTick, ref } from 'vue'
const source = ref('foo')
const { stop, pause, resume } = watchPausable(
source,
v => console.log(`Changed to ${v}!`),
)
source.value = 'bar'
await nextTick() // Changed to bar!
pause()
source.value = 'foobar'
await nextTick() // (nothing happend)
resume()
source.value = 'hello'
await nextTick() // Changed to hello!
