The <svelte:document>
element allows you to listen for events that fire on document
. This is useful with events like selectionchange
, which doesn’t fire on window
.
Add the onselectionchange
handler to the <svelte:document>
tag:
App
<svelte:document {onselectionchange} />
Avoid
mouseenter
andmouseleave
handlers on this element, as these events are not fired ondocument
in all browsers. Use<svelte:body>
instead.
