Svelte：手风琴拾音器的数据绑定

时间：2019-01-14 15:37:46

标签： typescript components accordion svelte

我正在玩Svelte（JS），以生产医疗调查专用应用程序。 我的数据是关于{类别，测试，子测试}

我需要使用手风琴子测试选择器来输入resumé条目。

一种设计选择是合并类别和测试级别，这取决于体积。 用户选择一个类别+测试，而手风琴则显示一个可供选择的子测试。

我对Svelte的双向数据绑定不是很熟悉。 我已经尝试过了，但是导致类型错误：'ctx.selected'未定义。

问题：

  1. 该如何解决？
  2. 如何在不查询服务器的情况下检索应用程序其他部分中的精选子测试？考虑我正在使用svelte-routing插件和商店

感谢答案。

1 个答案:

答案 0 :(得分：2)

基本上：

一个错误（丢失），当然要在数据部分添加selected: [] ...

并选择检测标题：

{#if selected.indexOf(ctidx) > -1 }
  {#each ct.subtests as sub, subidx }
    <div transition:fade>
      // ...
    </div>
   {/each}
 {/if}

那对我有用！
