Question

我正在查看vues页面上的教程以添加工具提示。 https://vuetifyjs.com/en/components/tooltips

对于单个按钮来说似乎工作正常。

但是，它在v项中不起作用。我收到一条控制台消息，说

'[[Vuetify] v-item缺少默认的scopedSlot'

<v-item v-for="foo in bars" :key=`${foo}`>
  <v-tooltip>
    <v-btn slot="activator">
      <v-icon>some-icon</v-icon>
    </v-btn>
    <span>Some tooltip text</span>
  </v-tooltip>
</v-item>

我曾尝试在上述代码中添加一些内容，例如在v-item中添加slot =“ activator”，在v-btn中添加slot-scope =“ activator”，但似乎没有任何工作可行。关于我在做什么错的任何建议吗？

Answer 1

调试代码段后，我通过向slot-scope="i"之类的tooltip组件添加<v-tooltip slot-scope="i" right>找到了解决方案：

new Vue({
  el: '#app',
  data() {
    return {
      bars: ['home', 'event', 'info']
    }
  }

})

<div id="app" data-app>
  <v-item-group >
    <v-container grid-list-md>
      <v-layout wrap>
        <v-flex v-for="(n,i) in bars" :key="n" xs12 md4>
          <v-item     >
            <v-tooltip   slot-scope="i" right>
              <v-btn slot="activator">
                <v-icon>{{n}}</v-icon>
              </v-btn>
              <span>{{n}}</span>
            </v-tooltip>
          </v-item>
        </v-flex>
      </v-layout>
    </v-container>
  </v-item-group>

</div>
