svelte - 如何在 Svelte 中动态渲染组件？

Question

我正在尝试遍历数组以呈现具有 type 值的组件。

<script>

import One from './One.svelte';    
import Two from './Two.svelte';
import Three from './Three.svelte';

const contents = [
 {type: 'One'},
 {type: 'Two'},
 {type: 'Three'},
 {type: 'One'}
]

</script>

{#each contents as content}
    <{content.type} />
{/each}

期望的输出:

<One />
<Two />
<Three />
<One />

执行此操作的最佳方法是什么？

使用 <svelte:component> :

The <svelte:component> element renders a component dynamically, usingthe component constructor specified as the this property. When theproperty changes, the component is destroyed and recreated.

例如:

<script>
    import One from './One.svelte';    
    import Two from './Two.svelte';

const contents = [
 One,
 Two
]
</script>

{#each contents as content}
    <svelte:component this={content}/>
{/each}
