templateRef

将 ref 绑定到模板元素的简写。

¥Shorthand for binding ref to template element.

用法

¥Usage

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

export default {
  setup() {
    const target = templateRef('target')

    // no need to return the `target`, it will bind to the ref magically
  },
}
</script>

<template>
  <div ref="target" />
</template>

使用 JSX/TSX

¥With JSX/TSX

import { templateRef } from '@vueuse/core'

export default {
  setup() {
    const target = templateRef<HTMLElement | null>('target', null)

    // use string ref
    return () => <div ref="target"></div>
  },
}

<script setup>

与 <script setup> 一起使用时不需要这样做，因为所有变量都会暴露给模板。它将与 ref 完全相同。

¥There is no need for this when using with <script setup> since all the variables will be exposed to the template. It will be exactly the same as ref.

<script setup lang="ts">
import { ref } from 'vue'

const target = ref<HTMLElement | null>(null)
</script>

<template>
  <div ref="target" />
</template>

类型声明

/**
 * Shorthand for binding ref to template element.
 *
 * @see https://vueuse.org/templateRef
 * @param key
 * @param initialValue
 */
export declare function templateRef<
  T extends HTMLElement | SVGElement | Component | null,
  Keys extends string = string,
>(key: Keys, initialValue?: T | null): Readonly<Ref<T>>
