useFocus

Reactive utility to track or set the focus state of a DOM element. State changes to reflect whether the target element is the focused element. Setting reactive value from the outside will trigger focus and blur events for true and false values respectively.

Basic Usage

import { useFocus } from '@vueuse/core'

const target = shallowRef()
const { focused } = useFocus(target)

watch(focused, (focused) => {
  if (focused)
    console.log('input element has been focused')
  else console.log('input element has lost focus')
})

Setting initial focus

To focus the element on its first render one can provide the initialValue option as true. This will trigger a focus event on the target element.

import { useFocus } from '@vueuse/core'

const target = shallowRef()
const { focused } = useFocus(target, { initialValue: true })

Change focus state

Changes of the focused reactive ref will automatically trigger focus and blur events for true and false values respectively. You can utilize this behavior to focus the target element as a result of another action (e.g. when a button click as shown below).

<script setup lang="ts">
import { useFocus } from '@vueuse/core'
import { shallowRef } from 'vue'

const input = shallowRef()
const { focused } = useFocus(input)
</script>

<template>
  <div>
    <button type="button" @click="focused = true">
      Click me to focus input below
    </button>
    <input ref="input" type="text">
  </div>
</template>

  /**
   * Initial value. If set true, then focus will be set on the target
   *
   * @default false
   */
  initialValue?: boolean

}
export interface UseFocusReturn {

   * If read as true, then the element has focus. If read as false, then the element does not have focus
   * If set to true, then the element will be focused. If set to false, the element will be blurred.
   */
  focused: WritableComputedRef<boolean>
}
/**
