基本用法

import { useMousePressed } from '@vueuse/core'

const { pressed } = useMousePressed()

默认情况下启用触摸。要使其仅检测鼠标更改，请将 touch 设置为 false

const { pressed } = useMousePressed({ touch: false })

要仅捕获特定元素上的 mousedown 和 touchstart，您可以通过传递元素的 ref 来指定 target。

vue

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

const el = useTemplateRef<HTMLDivElement>('el')

const { pressed } = useMousePressed({ target: el })
</script>

<template>
  <div ref="el">
    Only clicking on this element will trigger the update.
  </div>
</template>

组件用法

此函数还通过 @vueuse/components 包提供了一个无渲染组件版本。了解更多关于用法的信息。

vue

<template>
  <UseMousePressed v-slot="{ pressed }">
    Is Pressed: {{ pressed }}
  </UseMousePressed>
</template>
