extendRef
为 Ref 添加额外的属性。
用法
请注意，额外的属性将无法在 Vue 的模板中访问。
ts
import { extendRef } from '@vueuse/core'
import { shallowRef } from 'vue'
const myRef = shallowRef('content')
const extended = extendRef(myRef, { foo: 'extra data' })
extended.value === 'content'
extended.foo === 'extra data'Refs 将被解包并具有响应性
ts
const myRef = shallowRef('content')
const extraRef = shallowRef('extra')
const extended = extendRef(myRef, { extra: extraRef })
extended.value === 'content'
extended.extra === 'extra'
extended.extra = 'new data' // will trigger update
extraRef.value === 'new data'类型声明
ts
export type ExtendRefReturn<T = any> = Ref<T>
export interface ExtendRefOptions<Unwrap extends boolean = boolean> {
/**
* Is the extends properties enumerable
*
* @default false
*/
enumerable?: boolean
/**
* Unwrap for Ref properties
*
* @default true
*/
unwrap?: Unwrap
}
/**
* Overload 1: Unwrap set to false
*/
export declare function extendRef<
R extends Ref<any>,
Extend extends object,
Options extends ExtendRefOptions<false>,
>(ref: R, extend: Extend, options?: Options): ShallowUnwrapRef<Extend> & R
/**
* Overload 2: Unwrap unset or set to true
*/
export declare function extendRef<
R extends Ref<any>,
Extend extends object,
Options extends ExtendRefOptions,
>(ref: R, extend: Extend, options?: Options): Extend & R来源
