用法

¥Usage

与 watch 类似，但提供额外选项 debounce 和 maxWait，这些选项将应用于回调函数。

¥Similar to watch, but offering extra options debounce and maxWait which will be applied to the callback function.

import { watchDebounced } from '@vueuse/core'

watchDebounced(
  source,
  () => { console.log('changed!') },
  { debounce: 500, maxWait: 1000 },
)

它本质上是以下代码的简写：

¥It's essentially a shorthand for the following code:

import { debounceFilter, watchWithFilter } from '@vueuse/core'

watchWithFilter(
  source,
  () => { console.log('changed!') },
  {
    eventFilter: debounceFilter(500, { maxWait: 1000 }),
  },
)
