toRef
将值、ref 或 getter 规范化为 ref 或 computed。
用法
ts
import { toRef } from '@vueuse/core'
const foo = ref('hi')
const a = toRef(0) // Ref<number>
const b = toRef(foo) // Ref<string>
const c = toRef(() => 'hi') // ComputedRef<string>类型声明
typescript
/**
* 将值、ref 或 getter 规范化为 `ref` 或 `computed`。
*/
export declare function toRef<T>(r: () => T): Readonly<Ref<T>>
export declare function toRef<T>(r: ComputedRef<T>): ComputedRef<T>
export declare function toRef<T>(r: MaybeRefOrGetter<T>): Ref<T>
export declare function toRef<T>(r: T): Ref<T>
export declare function toRef<T extends object, K extends keyof T>(
object: T,
key: K,
): ToRef<T[K]>
export declare function toRef<T extends object, K extends keyof T>(
object: T,
key: K,
defaultValue: T[K],
): ToRef<Exclude<T[K], undefined>>
/**
* @deprecated use `toRef` instead
*/
export declare const resolveRef: typeof toRef源码
