响应式的指针状态。

示例

源码 playground (beta)

{
  "x": 0,
  "y": 0,
  "pointerId": 0,
  "pressure": 0,
  "tiltX": 0,
  "tiltY": 0,
  "width": 0,
  "height": 0,
  "twist": 0,
  "pointerType": null,
  "isInside": false
}

基本用法

import { usePointer
 } from '@vueuse/core'

const { x
, y
, pressure
, pointerType
 } = usePointer
()

组件用法

默认情况下，该组件将跟踪 window 上的指针。

vue

<template>
  <UsePointer v-slot="{ x
, y
 }">
    x: {{ x
 }}
    y: {{ y
 }}
  </UsePointer>
</template>

要在元素内跟踪本地位置，请设置 target="self"：

vue

<template>
  <UsePointer v-slot="{ x
, y
 }" target
="self">
    x: {{ x
 }} y: {{ y
 }}
  </UsePointer>
</template>
