响应式的鼠标按下状态。在目标元素上通过 mousedown touchstart 触发，在窗口上通过 mouseup mouseleave touchend touchcancel 释放。

Demo

source

pressed: false
sourceType: null

开启追踪

基本用法

import { useMousePressed } from '@vueuse/core'

const { pressed } = useMousePressed()

默认启用触摸。要使其仅检测鼠标变化，将 touch 设置为 false：

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

要仅在特定元素上捕获 mousedown 和 touchstart，你可以通过传递元素的 ref 来指定 target。

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

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

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

<template>
  <div ref="el">
    只有点击此元素才会触发更新。
  </div>
</template>

组件用法

<template>
  <UseMousePressed v-slot="{ pressed }">
    是否按下: {{ pressed }}
  </UseMousePressed>
</template>
