Advanced Usage & Customization

Feature Demo

Limit

use:clickoutside is registered for this green box. Try these:

  1. Click within this green zone => won't trigger on:clickoutside
  2. Click on the red zone => will trigger on:clickoutside
  3. Click outside the red limit => won't trigger on:clickoutside
  4. Enable/disable use:clickoutside with button below, then try (2) again

on:clickoutside counter: 0

<script lang="ts">
  import { clickoutside } from '@svelte-put/clickoutside';
  import { quintOut } from 'svelte/easing';
  import { fly } from 'svelte/transition';

  let enabled = true;
  let parent: Element;
  let click = 0;
  let cls = '';
  export { cls as class };

  function onClickOutside() {
    click++;
  }
  function toggleEnabled() {
    enabled = !enabled;
  }
</script>

<fieldset
  class="border-4 border-error-text bg-error-surface text-error-text p-10 {cls}"

Limit the Clickoutside Zone

As seen in demo above, the limit.parent option can be set to limit the zone that will trigger clickoutside CustomEvent. By default, there is no limit, and the event listener is attached to document.

<script lang="ts">
  let parentNode: HTMLElement;
</script>

<div bind:this={parentNode}>
  <div use:clickoutside={{ limit: { parent: parentNode } }}>...</div>
</div>

Event Type Customization

By default, clickoutside is based on the click event. You can customize this with the event option.

<div use:clickoutside={{ event: 'mousedown' }}>...</div>

AddEventListenerOptions

Additional options can be passed to addEventListener should it be necessary.

<div use:clickoutside={{ options: { passive: true } }}>...</div>

 <!-- options => useCapture -->
<div use:clickoutside={{ options: true }}>...</div>

Excluding Other Events in the Clickoutside Zone

In the Advanced Usage & Customization section, notice the stopPropagation modifier was added to the click event. Without this, the button would also trigger an clickoutside CustomEvent.

<button on:click|stopPropagation>...</button>

This makes sense since the button is technically outside of the element clickoutside is placed on, being within the “clickoutside zone”.

Be aware to reflect customization made to the event listener as mentioned in the last two sections. For example, if the mousedown event is used instead of click, add stopPropagation to mousedown on the element that should not trigger clickoutside.

<div use:clickoutside={{ event: 'mousedown' }}>...</div>

<!-- later -->
<button on:mousedown|stopPropagation>...</button>

Below is another demo where stopPropagation is generally recommended. Consider two buttons, each should trigger the corresponding box on its side:

  • The green toggle button behaves as expected. Notice the added |stopPropagation on this button.
  • The red toggle button does not behave as expected. Specifically:
    • when the left green box is toggled on, clicking on this red button causes the green box to toggled off, because the red button is indeed in outside the green box,
    • clicking on the red button does not seem to toggle the red box on, for the same reason as before: the box does indeed get toggled on, but immediately off again because the red button triggers both the toggling and the clickoutside events.
Example 
<script>
	import { clickoutside } from '@svelte-put/clickoutside';

  let leftOpen = true;
  function toggleLeft() {
    leftOpen = !leftOpen;
  }
  let rightOpen = false;
  function toggleRight() {
    rightOpen = !rightOpen;
  }

	let containerEl;
</script>

<div class="relative w-full overflow-hidden" bind:this={containerEl}>
	<div
		class="absolute inset-y-0 left-0 w-1/3 bg-success-surface text-success-text origin-left grid place-items-center transition-[opacity,transform] {leftOpen ? 'opacity-100 scale-x-100' : 'opacity-50 scale-x-50'}"
		use:clickoutside={{ enabled: leftOpen, limit: { parent: containerEl } }}
		on:clickoutside={toggleLeft}
	>
