Demo

使用

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

const htmlRefHook = useTemplateRef<HTMLElement>('htmlRefHook')
const longPressedHook = shallowRef(false)

function onLongPressCallbackHook(e: PointerEvent) {
  longPressedHook.value = true
}
function resetHook() {
  longPressedHook.value = false
}

onLongPress(
  htmlRefHook,
  onLongPressCallbackHook,
  {
    modifiers: {
      prevent: true
    }
  }
)
</script>

<template>
  <p>Long Pressed: {{ longPressedHook }}</p>

  <button ref="htmlRefHook" class="ml-2 button small">
    Press long
  </button>

  <button class="ml-2 button small" @click="resetHook">
    Reset
  </button>
</template>

组件方式使用

此函数也通过 @vueuse/components 包提供一个无渲染组件版本。了解更多用法。

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

const longPressedComponent = shallowRef(false)

function onLongPressCallbackComponent(e: PointerEvent) {
  longPressedComponent.value = true
}
function resetComponent() {
  longPressedComponent.value = false
}
</script>

<template>
  <p>Long Pressed: {{ longPressedComponent }}</p>

  <OnLongPress
    as="button"
    class="ml-2 button small"
    @trigger="onLongPressCallbackComponent"
  >
    Press long
  </OnLongPress>

  <button class="ml-2 button small" @click="resetComponent">
    Reset
  </button>
</template>

指令方式使用

此函数还通过 @vueuse/components 包提供了指令版本。了解更多关于用法的信息。

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

const longPressedDirective = shallowRef(false)

function onLongPressCallbackDirective(e: PointerEvent) {
  longPressedDirective.value = true
}
function resetDirective() {
  longPressedDirective.value = false
}
</script>

<template>
  <p>Long Pressed: {{ longPressedDirective }}</p>

  <button
    v-on-long-press.prevent="onLongPressCallbackDirective"
    class="ml-2 button small"
  >
    Press long
  </button>

  <button
    v-on-long-press="[onLongPressCallbackDirective, { delay: 1000, modifiers: { stop: true } }]"
    class="ml-2 button small"
  >
    Press long (with options)
  </button>

  <button class="ml-2 button small" @click="resetDirective">
    Reset
  </button>
</template>
