鼠标位置的响应式状态

Demo

基本用法

x: 0
y: 0
sourceType: null

reactive的使用

x: 0
y: 0
sourceType: null

基本用法

ts
import { 
useMouse
} from '@vueuse/core'
const {
x
,
y
,
sourceType
} =
useMouse
()

默认情况下启用了触摸功能。要仅检测鼠标变化,请将 touch 设置为 falsedragover 事件用于跟踪拖动时的鼠标位置。

ts
const { 
x
,
y
} =
useMouse
({
touch
: false })

自定义提取器

还可以提供自定义提取器函数来从事件中获取位置信息。

ts
import type { 
UseMouseEventExtractor
} from '@vueuse/core'
import {
useMouse
,
useParentElement
} from '@vueuse/core'
const
parentEl
=
useParentElement
()
const
extractor
:
UseMouseEventExtractor
=
event
=> (
event
instanceof
Touch
? null : [
event
.
offsetX
,
event
.
offsetY
]
) const {
x
,
y
,
sourceType
} =
useMouse
({
target
:
parentEl
,
type
:
extractor
})
js
import { useMouse, useParentElement } from '@vueuse/core'
const parentEl = useParentElement()
const extractor = (event) =>
  event instanceof Touch ? null : [event.offsetX, event.offsetY]
const { x, y, sourceType } = useMouse({ target: parentEl, type: extractor })

组件使用

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

类型声明

显示类型声明
typescript
export type UseMouseCoordType = "page" | "client" | "screen" | "movement"
export type UseMouseSourceType = "mouse" | "touch" | null
export type UseMouseEventExtractor = (
  event: MouseEvent | Touch,
) => [x: number, y: number] | null | undefined
export interface UseMouseOptions
  extends ConfigurableWindow,
    ConfigurableEventFilter {
  /**
   * 基于页面、客户端、屏幕或相对于上一个位置的鼠标位置
   *
   * @default 'page'
   */
  type?: UseMouseCoordType | UseMouseEventExtractor
  /**
   * 在`target`元素上监听事件
   *
   * @default 'Window'
   */
  target?: MaybeRefOrGetter<Window | EventTarget | null | undefined>
  /**
   * 监听 `touchmove` 事件
   *
   * @default true
   */
  touch?: boolean
  /**
   * 在窗口上监听 `scroll` 事件,仅在 `type` 为 `page` 时有效
   *
   * @default true
   */
  scroll?: boolean
  /**
   * 当触发 `touchend` 事件时重置为初始值
   *
   * @default false
   */
  resetOnTouchEnds?: boolean
  /**
   * 初始值
   */
  initialValue?: Position
}
/**
 * 响应式鼠标位置。
 *
 * @see https://vueuse.org/useMouse
 * @param options
 */
export declare function useMouse(options?: UseMouseOptions): {
  x: Ref<number, number>
  y: Ref<number, number>
  sourceType: Ref<UseMouseSourceType, UseMouseSourceType>
}
export type UseMouseReturn = ReturnType<typeof useMouse>
