将整个应用放在一个组件中是不切实际的。相反,我们可以从其他文件导入组件并将它们包含在我们的标记中。
¥It would be impractical to put your entire app in a single component. Instead, we can import components from other files and include them in our markup.
在 App.svelte
顶部添加一个 <script>
标签,导入 Nested.svelte
...
¥Add a <script>
tag to the top of App.svelte
that imports Nested.svelte
...
App
<script>
import Nested from './Nested.svelte';
</script>
<script lang="ts">
import Nested from './Nested.svelte';
</script>
...并包含 <Nested />
组件:
¥...and include a <Nested />
component:
App
<p>This is a paragraph.</p>
<Nested />
请注意,即使 Nested.svelte
具有 <p>
元素,App.svelte
中的样式也不会泄漏。
¥Notice that even though Nested.svelte
has a <p>
element, the styles from App.svelte
don’t leak in.
组件名称大写,以区别于 HTML 元素。
¥[!NOTE] Component names are capitalised, to distinguish them from HTML elements.
