用法

🌐 Usage

像平常一样使用 watch，但返回额外的 pause() 和 resume() 函数以进行控制。

🌐 Use as normal the watch, but return extra pause() and resume() functions to control.

import { watchPausable } from '@vueuse/core'
import { nextTick, shallowRef } from 'vue'

const source = shallowRef('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!
