Usage ​

Basic Usage

vue
<script setup>
import { useFocusTrap } from '@vueuse/integrations/useFocusTrap'
import { ref } from 'vue'

const target = ref()
const { hasFocus, activate, deactivate } = useFocusTrap(target)
</script>

<template>
  <div>
    <button @click="activate()">
      Activate
    </button>
    <div ref="target">
      <span>Has Focus: {{ hasFocus }}</span>
      <input type="text">
      <button @click="deactivate()">
        Deactivate
      </button>
    </div>
  </div>
</template>

Multiple Refs

vue
<script setup>
import { useFocusTrap } from '@vueuse/integrations/useFocusTrap'
import { ref } from 'vue'

const targetOne = ref()
const targetTwo = ref()
const { hasFocus, activate, deactivate } = useFocusTrap([targetOne, targetTwo])
</script>

<template>
  <div>
    <button @click="activate()">
      Activate
    </button>
    <div ref="targetOne">
      <span>Has Focus: {{ hasFocus }}</span>
      <input type="text">
    </div>
    ...
    <div ref="targetTow">
      <p>Another target here</p>
      <input type="text">
      <button @click="deactivate()">
        Deactivate
      </button>
    </div>
  </div>
</template>

Automatically Focus

vue
<script setup>
import { useFocusTrap } from '@vueuse/integrations/useFocusTrap'
import { ref } from 'vue'

const target = ref()
const { hasFocus, activate, deactivate } = useFocusTrap(target, { immediate: true })
</script>

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

Conditional Rendering

This function can't properly activate focus on elements with conditional rendering using v-if. This is because they do not exist in the DOM at the time of the focus activation. To solve this you need to activate on the next tick.

vue
<script setup>
import { nextTick, ref } from 'vue'

const target = ref()
const { activate, deactivate } = useFocusTrap(target, { immediate: true })

const show = ref(false)

async function reveal() {
  show.value = true

  await nextTick()
  activate()
}
</script>

<template>
  <div>
    <div v-if="show" ref="target">
      ...
    </div>

    <button @click="reveal">
      Reveal and Focus
    </button>
  </div>
</template>

Using Component ​

With the UseFocusTrap component, Focus Trap will be activated automatically on mounting this component and deactivated on unmount.

vue
<script setup>
import { UseFocusTrap } from '@vueuse/integrations/useFocusTrap/component'
import { ref } from 'vue'

const show = ref(false)
</script>

<template>
  <UseFocusTrap v-if="show" :options="{ immediate: true }">
    <div class="modal">
      ...
    </div>
  </UseFocusTrap>
</template>
