<svelte:self>

The <svelte:self> 元素允许组件递归地包含自身。

它不能出现在您的标记的顶层；它必须位于 if 或 each 块内部，或者传递给组件的 slot，以防止无限循环。

<script>
	export let count;
</script>

{#if count > 0}
	<p>counting down... {count}</p>
	<svelte:self count={count - 1} />
{:else}
	<p>lift-off!</p>
{/if}

[注意] 此概念已过时，因为组件可以导入自身：

App

<script>
	import Self from './App.svelte'
	export let count;
</script>

{#if count > 0}
	<p>counting down... {count}</p>
	<Self count={count - 1} />
{:else}
	<p>lift-off!</p>
{/if}

<script lang="ts">
	import Self from './App.svelte'
	export let count;
</script>

{#if count > 0}
	<p>counting down... {count}</p>
	<Self count={count - 1} />
{:else}
	<p>lift-off!</p>
{/if}
