[inside5545]

比如官网示例，如何获取到class="item"的所有dom：
For example, the official website example, how to get all the dom of class="item" :

<FancyList :api-url="url" :per-page="10">
  <template #item="{ body, username, likes }">
    <div class="item">
      <p>{{ body }}</p>
      <p>by {{ username }} | {{ likes }} likes</p>
    </div>
  </template>
</FancyList>

<!--FancyList.vue-->
<ul>
  <li v-for="item in items">
    <slot name="item" v-bind="item"></slot>
  </li>
</ul>

  return () => h('div')
})
