如何在每个“v-list-item”之间有“v-divider”组件？

Question

我试图根据我有多少个答案来迭代 v-divider，以便每个答案都有一个分隔符 (4)。从官方文档的一个例子中得到提示，我正在尝试类似的事情，但我无法理解，有人可以向我解释我错在哪里？

这是代码：

<template>
  <div class="dark2">
    <v-card max-width="600" class="mx-auto">
      <v-toolbar extended class="mt-10" color="light-blue" dark>
        <v-toolbar-title class="flex text-center">
          <h2 class="text-center mt-10">Quiz Dark 2</h2>
        </v-toolbar-title>
      </v-toolbar>

      <v-progress-linear :value="progress"></v-progress-linear>

      <v-list subheader two-line v-for="(element, index) in questions.slice(a,b)" :key="index" v-show="quiz">
        <h1 class="text-center my-4">Domanda {{ b }}/{{ questions.length }}</h1>
        <v-list-item class="d-flex justify-center text-center">{{ element.question }}</v-list-item>
        <v-divider class="mt-10"></v-divider>

        <v-list-item-group active-class="pink--text">
          <v-list-item class="d-flex justify-center my-2" v-for="(item, index) in element.suggestions" :key="index">
            {{ item.suggestion }}
          </v-list-item>
          <v-divider v-if="index < questions.length - 1"
                     :key="index"></v-divider>
        </v-list-item-group>
      </v-list>

    </v-card>
  </div>
</template>

<script>
export default {
  data() {
    return {
      questions: [
        {
          question: 'Cosa lascia Micheal kanhnwald a suo figlio Jonas prima di impiccarsi?',
          suggestions: [
            {suggestion: 'Un libro'},
            {suggestion: 'Una lettera'},
            {suggestion: 'Una torcia futuristica'},
            {suggestion: 'Un contatore Geiger'}
          ]
        }
      ],
      a: 0,
      b: 1,
      select: false,
      score: 0,
      quiz: true,
      score_show: false,
      next: false,
      progress: 0
    }
  }
}
</script>

正如您在 Vuetify 官方文档Lists Component / Action stack提供的示例中看到的，您template的标签内应该有一个标签v-list-item-group。像这样的东西：

  <v-list-item-group active-class="pink--text">
    <template v-for="(item, index) in element.suggestions">
      <v-list-item class="d-flex justify-center my-2" :key="index">
        {{ item.suggestion }}
      </v-list-item>
      <v-divider
          v-if="index < element.suggestions.length - 1"
          :key="`${index}-divider`"
      ></v-divider>
    </template>
  </v-list-item-group>

唯一的区别是拥有templateinside v-list-item-group，然后添加v-divider到v-list-itemcustom 内部template。

希望它有所帮助，编码愉快。
