在 Vue.JS 中为 div 生成 id

Question

考虑 Bootstrap 手风琴：

  <div class="card">
    <div class="card-header" role="tab" id="headingOne">
      <div data-toggle="collapse" data-parent="#accordion" href="#collapseOne" aria-expanded="true" aria-controls="collapseOne">
       i'm not collapsed
    </div>

    <div id="collapseOne" class="collapse show" role="tabpanel" aria-labelledby="headingOne">
      <div class="card-block">
        Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson ad squid. 3 wolf moon officia aute, non cupidatat skateboard dolor brunch. Food truck quinoa nesciunt laborum eiusmod. Brunch 3 wolf moon tempor, sunt aliqua put a bird

      </div>
    </div>
  </div>

      </div>

我想用 vue 动态生成里面的卡片，所以我可以在卡片上添加这一行：

  <div class="card" v-for="x in response">

它会为每个人生成一张卡片。但是，它们都引用相同的 id 进行折叠，因此只有其中一个打开/关闭。

为了解决这个问题，我尝试改变id来改变这些行：

  <div class="card" v-for="(x,index) in response">

 <div id="{{index}}" class="collapse show" role="tabpanel" aria-labelledby="headingOne">

但这不会编译。我想不出任何其他方法来解决这个问题。我会很感激任何建议。

不要在属性中使用插值，而是使用绑定

<div class="card" v-for="(x,index) in response">
  <div :id="index" class="collapse show" role="tabpanel" aria-labelledby="headingOne"></div>
</div>
