Question

我在某些组件上使用了范围样式。样式类使用[data-v-hash]呈现，并且html元素获得[data-v-hash]属性...但不是全部...为什么？

让我们来看看这个navbar bootstrap4 navbar

    <template>
<nav class="navbar navbar-inverse navbar-light fixed-top navbar-expand-lg">
  <a class="navbar-brand" href="#">Home</a>
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
  </button>

  <div class="collapse navbar-collapse" id="navbarSupportedContent">
    <ul class="navbar-nav mr-auto">
      <li class="nav-item dropdown">
        <a class="nav-link dropdown-toggle" href="#" id="navbarDropdown" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
          Menu
        </a>
        <div class="dropdown-menu" aria-labelledby="navbarDropdown">
          <a class="dropdown-item" href="#">item1</a>
          <a class="dropdown-item" href="#">item2</a>
        </div>
      </li>

    </ul>

  </div>
</nav>

</template>

然后我使用自定义范围的CSS，例如

.navbar-brand{
    text-shadow: none;
    color: #737373;
    font-size:16px;
}

渲染后样式变为

.navbar-brand[data-v-9fbb962c]{
    text-shadow: none;
    color: #737373;
    font-size:16px;
}

但是HTML仍然是

<a href="/admin" class="navbar-brand">Home</a>

而其他元素正确获得了data-v属性

作用域样式v数据-不适用于所有元素
