useCurrentElement
Get the DOM element of current component as a ref.
Usage
import { useCurrentElement } from '@vueuse/core'
const el = useCurrentElement() // ComputedRef<Element>
Or pass a specific vue component
<script setup lang="ts">
import { useCurrentElement, VueInstance } from '@vueuse/core'
import { shallowRef } from 'vue'
const componentRef = shallowRef<VueInstance>(null as unknown as VueInstance)
const el = useCurrentElement(componentRef) // ComputedRef<Element>
</script>
<template>
<div>
<OtherVueComponent ref="componentRef" />
<p>Hello world</p>
</div>
</template>
Caveats
This functions uses $el under the hood.
Value of the ref will be undefined until the component is mounted.
- For components with a single root element, it will point to that element.
- For components with text root, it will point to the text node.
- For components with multiple root nodes, it will be the placeholder DOM node that Vue uses to keep track of the component's position in the DOM.
It's recommend to only use this function for components with a single root element.
Type Declarations
export declare function useCurrentElement<
T extends MaybeElement = MaybeElement,
R extends VueInstance = VueInstance,
E extends MaybeElement = MaybeElement extends T
? IsAny<R["$el"]> extends false
? R["$el"]
: T
: T,
>(rootComponent?: MaybeElementRef<R>): ComputedRefWithControl<E>
