用法

¥Usage

<script setup lang="ts">
import { useDraggable } from '@vueuse/core'
import { useTemplateRef } from 'vue'

const el = useTemplateRef<HTMLElement>('el')

// `style` will be a helper computed for `left: ?px; top: ?px;`
const { x, y, style } = useDraggable(el, {
  initialValue: { x: 40, y: 40 },
})
</script>

<template>
  <div ref="el" :style="style" style="position: fixed">
    Drag me! I am at {{ x }}, {{ y }}
  </div>
</template>

设置 preventDefault: true 以覆盖浏览器中某些元素的默认拖放行为。

¥Set preventDefault: true to override the default drag-and-drop behavior of certain elements in the browser.

const { x, y, style } = useDraggable(el, {
  preventDefault: true,
  // with `preventDefault: true`
  // you can disable the native behavior (e.g., for img)
  // and control the drag-and-drop, preventing the browser interference.
})

组件用法

¥Component Usage

<template>
  <UseDraggable v-slot="{ x, y }" :initial-value="{ x: 10, y: 10 }">
    Drag me! I am at {{ x }}, {{ y }}
  </UseDraggable>
</template>

对于组件使用，可以将附加属性 storageKey 和 storageType 传递给组件并启用元素位置的持久性。

¥For component usage, additional props storageKey and storageType can be passed to the component and enable the persistence of the element position.

<template>
  <UseDraggable storage-key="vueuse-draggable" storage-type="session">
    Refresh the page and I am still in the same position!
  </UseDraggable>
</template>
