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>
  <UseMouseInElement v-slot="{ elementX, elementY, isOutside }">
    x: {{ elementX }}
    y: {{ elementY }}
    Is Outside: {{ isOutside }}
  </UseMouseInElement>
</template>

指令用法

此函数还通过 @vueuse/components 包提供了一个指令版本。了解更多关于用法的信息。

vue

<script setup lang="ts">
import { vMouseInElement } from '@vueuse/components'
import { UseMouseSourceType } from '@vueuse/core'

interface MouseInElementType {
  x: number
  y: number
  sourceType: UseMouseSourceType
  elementX: number
  elementY: number
  elementPositionX: number
  elementPositionY: number
  elementHeight: number
  elementWidth: number
  isOutside: boolean
}

const options = {
  handleOutside: true
}
function onMouseInElement({ x, y, sourceType, elementX, elementY, elementPositionX, elementPositionY, elementHeight, elementWidth, isOutside }: MouseInElementType) {
  console.log(x, y, sourceType, elementX, elementY, elementPositionX, elementPositionY, elementHeight, elementWidth, isOutside)
}
