VueUse中文文档extendRef
Add extra attributes to Ref.
Usage
This function is NOT compatible with Vue 2.6 or below.
Please note the extra attribute will not be accessible in Vue's template.
ts
import { ref } from 'vue'
import { extendRef } from '@vueuse/core'
const myRef = ref('content')
const extended = extendRef(myRef, { foo: 'extra data' })
extended.value === 'content'
extended.foo === 'extra data'
import { ref } from 'vue'
import { extendRef } from '@vueuse/core'
const myRef = ref('content')
const extended = extendRef(myRef, { foo: 'extra data' })
extended.value === 'content'
extended.foo === 'extra data'
Refs will be unwrapped and be reactive
ts
const myRef = ref('content')
const extraRef = ref('extra')
const extended = extendRef(myRef, { extra: extraRef })
extended.value === 'content'
extended.extra === 'extra'
extended.extra = 'new data' // will trigger update
extraRef.value === 'new data'
const myRef = ref('content')
const extraRef = ref('extra')
const extended = extendRef(myRef, { extra: extraRef })
extended.value === 'content'
extended.extra === 'extra'
extended.extra = 'new data' // will trigger update
extraRef.value === 'new data'
