Svelte 3 中是否存在动态道具 [英] Do dynamic props exist in Svelte 3

问题描述

当我迭代一个动态组件时:

When I iterate over a dynamic component like:

<svelte:component collection={collection} uid={uid} this={upload_component} 
     bind:action={restart}/>

是否可以为每个组件使用一组动态道具.每个组件都有自己的一组道具名称和道具值.

Is it possible to use a set of dynamic props for each component. Each component having it's own set of prop names and prop values.

解决方案示例:

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

    const pkgs = [{
        name: 'svelte',
        version: 3,
        speed: 'blazing',
        website: 'https://svelte.dev'
    }, ];
</script>

<Info {...pkgs[0]}/>

推荐答案

是的.你需要传播道具:

<svelte:component this={upload_component} bind:action={restart} {...someprops}/>

(注意绑定和事件监听器不包含在这些 props 中——但是你总是可以在你的 props 之间传递一个回调函数.)

(Note that bindings and event listeners are not included in those props — but you can always pass down a callback function among your props.)
