useMousePressed

响应式鼠标按下状态。通过在目标元素上的 mousedown 和 touchstart 事件触发，并通过在窗口上的 mouseup、mouseleave、touchend 和 touchcancel 事件释放。

基本用法

import { useMousePressed } from '@vueuse/core'

const { pressed } = useMousePressed()

默认启用触控。若要 仅检测鼠标变化，请将 touch 设置为 false。

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

若要仅捕获 特定元素上的 mousedown 和 touchstart 事件，你可以通过传递元素的引用来指定 target。

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

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

<template>
  <div ref="el">
    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 无渲染组件版本。了解更多关于用法的信息。

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