在两个其他值之间响应式地夹取一个值。

示例

源码 playground (beta)

min: max: value:0

用法

import { useClamp
 } from '@vueuse/math'

const min
 = shallowRef
(0)
const max
 = shallowRef
(10)
const value
 = useClamp
(0, min
, max
)

你也可以传递一个 ref，当源 ref 发生变化时，返回的 computed 将会被更新：

import { useClamp
 } from '@vueuse/math'

const number
 = shallowRef
(0)
const clamped
 = useClamp
(number
, 0, 10)
