用法

¥Usage

与 watch 类似，但提供了一个额外的选项 throttle，该选项将应用于回调函数。

¥Similar to watch, but offering an extra option throttle which will be applied to the callback function.

import { watchThrottled } from '@vueuse/core'

watchThrottled(
  source,
  () => { console.log('changed!') },
  { throttle: 500 },
)

它本质上是以下代码的简写：

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

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

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