如何在 Svelte 中动态渲染组件? [英] How to dynamically render components in Svelte?

问题描述

我正在尝试遍历一个数组以呈现具有 type 值的组件.

Im trying to loop through an array to render the component with the value of type.

<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}

所需的输出:

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

最好的方法是什么?

推荐答案

使用 :

元素动态呈现组件，使用指定为 this 属性的组件构造函数.当...的时候属性发生变化，组件被销毁并重新创建.

The <svelte:component> element renders a component dynamically, using the component constructor specified as the this property. When the property 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}
