用法

¥Usage

<script setup>
import { ref } from 'vue'
import { onClickOutside } from '@vueuse/core'

const target = ref(null)

onClickOutside(target, event => console.log(event))
</script>

<template>
  <div ref="target">
    Hello world
  </div>
  <div>Outside element</div>
</template>

此函数使用 Event.composedPath()，IE 11、Edge 18 及以下版本不支持。如果你的目标是这些浏览器，我们建议你在项目中包含 这段代码片段。

¥This function uses Event.composedPath() which is NOT supported by IE 11, Edge 18 and below. If you are targeting these browsers, we recommend you to include this code snippet on your project.

组件用法

¥Component Usage

<template>
  <OnClickOutside :options="{ ignore: [/* ... */] }" @trigger="count++">
    <div>
      Click Outside of Me
    </div>
  </OnClickOutside>
</template>

指令用法

¥Directive Usage

<script setup lang="ts">
import { ref } from 'vue'
import { vOnClickOutside } from '@vueuse/components'

const modal = ref(false)
function closeModal() {
  modal.value = false
}
</script>

<template>
  <button @click="modal = true">
    Open Modal
  </button>
  <div v-if="modal" v-on-click-outside="closeModal">
    Hello World
  </div>
</template>

还可以将 handler 设置为数组来设置指令的配置项。

¥You can also set the handler as an array to set the configuration items of the instruction.

<script setup>
import { ref } from 'vue'
import { vOnClickOutside } from '@vueuse/components'

const modal = ref(false)

const ignoreElRef = ref()

const onClickOutsideHandler = [
  (ev) => {
    console.log(ev)
    modal.value = false
  },
  { ignore: [ignoreElRef] },
]
</script>

<template>
  <button @click="modal = true">
    Open Modal
  </button>

  <div ref="ignoreElRef">
    click outside ignore element
  </div>

  <div v-if="modal" v-on-click-outside="onClickOutsideHandler">
    Hello World
  </div>
</template>

类型声明

export interface OnClickOutsideOptions extends ConfigurableWindow {
  /**
   * List of elements that should not trigger the event.
   */
  ignore?: (MaybeElementRef | string)[]
  /**
   * Use capturing phase for internal event listener.
   * @default true
   */
  capture?: boolean
  /**
   * Run handler function if focus moves to an iframe.
   * @default false
   */
  detectIframe?: boolean
}
export type OnClickOutsideHandler<
  T extends {
    detectIframe: OnClickOutsideOptions["detectIframe"]
  } = {
    detectIframe: false
  },
> = (
  evt: T["detectIframe"] extends true
    ? PointerEvent | FocusEvent
    : PointerEvent,
) => void
/**
 * Listen for clicks outside of an element.
 *
 * @see https://vueuse.org/onClickOutside
 * @param target
 * @param handler
 * @param options
 */
export declare function onClickOutside<T extends OnClickOutsideOptions>(
  target: MaybeElementRef,
  handler: OnClickOutsideHandler<{
    detectIframe: T["detectIframe"]
  }>,
  options?: T,
): () => void
