从 module 脚本块导出的任何内容都将成为模块本身的导出。让我们导出一个 stopAll 函数：
¥Anything exported from a module script block becomes an export from the module itself. Let’s export a stopAll function:
AudioPlayer
<script module>
let current;
export function stopAll() {
current?.pause();
}
</script>我们现在可以在 App.svelte 中导入 stopAll...
¥We can now import stopAll in App.svelte...
App
<script>
import AudioPlayer, { stopAll } from './AudioPlayer.svelte';
import { tracks } from './tracks.js';
</script><script lang="ts">
import AudioPlayer, { stopAll } from './AudioPlayer.svelte';
import { tracks } from './tracks.js';
</script>...并在事件处理程序中使用它:
¥...and use it in an event handler:
App
<div class="centered">
{#each tracks as track}
<AudioPlayer {...track} />
{/each}
<button onclick={stopAll}>
stop all
</button>
</div>你不能有默认导出，因为组件是默认导出。
¥[!NOTE] You can’t have a default export, because the component is the default export.
