第一次尝试：

<button type="submit" class="button" {{#if isDirty(item)}}disabled{{/if}}>Save2</button>

在编译期间导致错误：

bundling...
   (svelte plugin) Error: (28:75) Expected >
26:         <div class="row">
27:           <!-- FIXME Can't set an attribute dynamically? -->
28:           <button type="submit" class="button" {{#if isDirty(item)}}disabled{{/if}}>Save2</button>
                                                                               ^

我能想到的最好的：

{{#if isDirty(item)}}
  <button type="submit" class="button" disabled>Save</button>
{{else}}
  <button type="submit" class="button">Save</button>
{{/if}}
