Question

<ul if.bind="imageSizes">
  <li repeat.for="type of types">
    <a href="#">(${ imageSizes.${type} }px)</a>
  </li>
</ul>

我尝试使用中继器复制以下代码：

<li if.bind="imageSizes.original">
  <a href="#"> (${ imageSizes.original }px)</a>
</li>
<li if.bind="imageSizes.largeweb">
  <a href="#"> (${ imageSizes.largeweb }px)</a>
</li>
<li if.bind="imageSizes.web">
  <a href="#"> (${ imageSizes.web }px)</a>
</li>
<li if.bind="imageSizes.tab">
  <a href="#"> (${ imageSizes.tab }px)</a>
</li>
<li if.bind="imageSizes.mobile">
  <a href="#"> (${ imageSizes.mobile }px)</a>
</li>
<li if.bind="imageSizes.thumb">
  <a href="#"> (${ imageSizes.thumb }px)</a>
</li>

是否可以在这里使用类似${imageSizes.${type}}px的东西？

正确的格式是

<ul if.bind="imageSizes">
  <li repeat.for="type of types" if.bind="imageSizes[type]">
    <a href="#">(${imageSizes[type]})px</a>
  </li>
</ul>
