# onClickOutside

Listen for clicks outside of an element. Useful for modals or dropdowns.

## Usage

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

const target = useTemplateRef('target')

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

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

### Return Value

By default, `onClickOutside` returns a `stop` function to remove the event listeners.

```ts
const stop = onClickOutside(target, handler)

// Later, stop listening
stop()
```

### Controls

If you need more control over triggering the handler, you can use the `controls` option. This returns an object with `stop`, `cancel`, and `trigger` functions.

```ts
const { stop, cancel, trigger } = onClickOutside(
  modalRef,
  (event) => {
    modal.value = false
  },
  { controls: true },
)

// cancel prevents the next click from triggering the handler
cancel()

// trigger manually fires the handler
trigger(event)

// stop removes all event listeners
stop()
```

### Ignore Elements

Use the `ignore` option to prevent certain elements from triggering the handler. Provide elements as an array of Refs or CSS selectors.

```ts
const ignoreElRef = useTemplateRef('ignoreEl')

onClickOutside(
  target,
  event => console.log(event),
  { ignore: [ignoreElRef, '.ignore-class', '#ignore-id'] },
)
```

### Capture Phase

By default, the event listener uses the capture phase (`capture: true`). Set `capture: false` to use the bubbling phase instead.

```ts
onClickOutside(target, handler, { capture: false })
```

### Detect Iframe Clicks

Clicks inside an iframe are not detected by default. Enable `detectIframe` to also trigger the handler when focus moves to an iframe.

```ts
onClickOutside(target, handler, { detectIframe: true })
```

## Component Usage

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

## Directive Usage

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

const modal = shallowRef(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>
```

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

```vue
<script setup lang="ts">
import { vOnClickOutside } from '@vueuse/components'
import { shallowRef, useTemplateRef } from 'vue'

const modal = shallowRef(false)

const ignoreElRef = useTemplateRef('ignoreEl')

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>
```

## Type Declarations

```ts
export interface OnClickOutsideOptions<
  Controls extends boolean = false,
> extends ConfigurableWindow {
  /**
   * List of elements that should not trigger the event,
   * provided as Refs or CSS Selectors.
   */

   * Use capturing phase for internal event listener.
   * @default true
   */
  capture?: boolean
  /**
   * Run handler function if focus moves to an iframe.
   * @default false
   */
  detectIframe?: boolean
  /**
   * Use controls to cancel/trigger listener.
   * @default false
   */
  controls?: Controls
}
export type OnClickOutsideHandler<
  T extends OnClickOutsideOptions<boolean> = OnClickOutsideOptions,
> = (
  event:
    | (T["detectIframe"] extends true ? FocusEvent : never)
    | (T["controls"] extends true ? Event : never)
    | PointerEvent,
) => void
export type OnClickOutsideReturn<Controls extends boolean = false> =
  Controls extends false
    ? Fn
    : {
        stop: Fn
        cancel: Fn
        trigger: (event: Event) => void
      }
/**
 * Listen for clicks outside of an element.
 *
 * @see https://vueuse.org/onClickOutside

 * @param handler
 * @param options
 */
export declare function onClickOutside<T extends OnClickOutsideOptions>(
  target: MaybeComputedElementRef,
  handler: OnClickOutsideHandler<T>,
  options?: T,

export declare function onClickOutside<T extends OnClickOutsideOptions<true>>(
