<svelte:document>

<svelte:document onevent={handler} />

<svelte:document bind:prop={value} />

与 <svelte:window> 类似，此元素允许你向 document 上的事件添加监听器，例如 visibilitychange，这些事件不会在 window 上触发。它还允许你在 document 上使用 actions。

¥Similarly to <svelte:window>, this element allows you to add listeners to events on document, such as visibilitychange, which don’t fire on window. It also lets you use actions on document.

与 <svelte:window> 一样，此元素可能仅出现在组件的顶层，并且绝不能位于块或元素内。

¥As with <svelte:window>, this element may only appear the top level of your component and must never be inside a block or element.

<svelte:document onvisibilitychange={handleVisibilityChange} use:someAction />

你还可以绑定到以下属性：

¥You can also bind to the following properties:

• activeElement

• fullscreenElement

• pointerLockElement

• visibilityState

全部都是只读的。

¥All are readonly.
