從 module script 區塊匯出的任何內容都會變成模組本身的匯出。讓我們匯出一個 stopAll 函數
AudioPlayer
<script module>
let current;
export function stopAll() {
current?.pause();
}
</script>我們現在可以在 App.svelte 中匯入 stopAll...
App
<script>
import AudioPlayer, { stopAll } from './AudioPlayer.svelte';
import { tracks } from './tracks.js';
</script>...並在事件處理器中使用它
App
<div class="centered">
{#each tracks as track}
<AudioPlayer {...track} />
{/each}
<button onclick={stopAll}>
stop all
</button>
</div>你不能有預設匯出，因為元件是預設匯出。
