In Aurelia, can a slot be used in a repeat.for binding?

问题

I'd like to create a custom element that loops through an array and applies the to each item in the array. For example, the view template of the custom element would contain something like:

<div repeat.for="i of items">
  <div with.bind="i">
    <slot></slot>
  </div>
</div>

When I remove the repeat.for and with.bind attributes, the slot displays a single time. Is there a way to make it repeat for each item in the list?

回答1:

No, you cannot use slots with repeat.for or bind today. To do this you have to use replaceable parts. For example:

<div repeat.for="i of items">
  <div with.bind="i">
    <template replaceable part="content"></template>
  </div>
</div>

Usage:

<my-component>
  <template replace-part="content">Some Content - ${somePropertyOfI}</template>
</my-component>
