扩展了 toRefs，它也接受一个对象的 refs。

用法

import { toRefs
 } from '@vueuse/core'
import { reactive
, ref
 } from 'vue'

const objRef
 = ref
({ a
: 'a', b
: 0 })
const arrRef
 = ref
(['a', 0])

const { a
, b
 } = toRefs
(objRef
)
const [a
, b
] = toRefs
(arrRef
)

const obj
 = reactive
({ a
: 'a', b
: 0 })
const arr
 = reactive
(['a', 0])

const { a
, b
 } = toRefs
(obj
)
const [a
, b
] = toRefs
(arr
)

用例

解构一个 props 对象

vue

<script lang="ts">
import { toRefs
, useVModel
 } from '@vueuse/core'

export default {
  setup
(props
) {
    const refs
 = toRefs
(useVModel
(props
, 'data'))

    console
.log
(refs
.a.value) // props.data.a
    refs
.a.value = 'a' // emit('update:data', { ...props.data, a: 'a' })

    return { ...refs
 }
  }
}
</script>

<template>
  <div
>
    <input
 v-model
="a" type
="text">
    <input
 v-model
="b" type
="text">
  </div
>
</template>
