useMousePressed

Demo

pressed: false
sourceType: null

开启追踪

基本用法

import { useMousePressed } from '@vueuse/core'

const { pressed } = useMousePressed()

默认情况下启用触摸。要使其仅检测鼠标变化，将 touch 设置为 false

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

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

vue

<script>
const el = ref(null)

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

<template>
  <div ref="el">
    仅点击此元素将触发更新。
  </div>
</template>

组件用法

vue

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