上一章節(jié)使用了一個(gè)默認(rèn)插槽（default slot），該slot直接在組件內(nèi)顯示，有時(shí)候你需要對(duì)子級(jí)進(jìn)行細(xì)分設(shè)置，就如這個(gè)<ContactCard>。在這種情況下，我們可以使用 命名插槽（named slots）。

在ContactCard.svelte中，給每個(gè)標(biāo)簽添加name屬性：

<article class="contact-card">
	<h2>
		<slot name="name">
			<span class="missing">Unknown name</span>
		</slot>
	</h2>

	<div class="address">
		<slot name="address">
			<span class="missing">Unknown address</span>
		</slot>
	</div>

	<div class="email">
		<slot name="email">
			<span class="missing">Unknown email</span>
		</slot>
	</div>
</article>

然后把 slot="..." 添加到 <ContactCard> 標(biāo)簽內(nèi)：

<ContactCard>
	<span slot="name">
		P. Sherman
	</span>

	<span slot="address">
		42 Wallaby Way<br>
		Sydney
	</span>
</ContactCard>

示例代碼

• App.svelte

<script>
	import ContactCard from './ContactCard.svelte';
</script>

<ContactCard>
	<span slot="name">
		P. Sherman
	</span>

	<span slot="address">
		42 Wallaby Way<br>
		Sydney
	</span>
</ContactCard>
