缺少默认作用域插槽Vuetify [英] Missing a default scoped slot Vuetify

问题描述

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

I am looking at the tutorials on vues page for adding tooltips. https://vuetifyjs.com/en/components/tooltips

对于单个按钮来说似乎工作正常.

It seems to work fine for an individual button.

但是，它在v项中不起作用.我收到一条控制台消息，说

However, it does not work within a v-item. I get a console message saying

'[[Vuetify] v-item缺少默认的scopedSlot'

'[Vuetify] v-item is missing a default 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>

我已经尝试在上述代码中添加一些内容，例如将slot ="activator"添加到v-item，将slot-scope ="activator"添加到v-btn，但是似乎没有任何工作正常.关于我在做什么错的任何建议吗?

I've tried adding things to the above code like slot="activator" to v-item and slot-scope="activator" to the v-btn, but nothing seems to work quite right. Any suggestions as to what I'm doing wrong?

推荐答案

调试代码段后，我通过将slot-scope="i"添加到tooltip组件(如<v-tooltip slot-scope="i" right>)中找到了解决方案:

After debugging the Code snippet i found the solution by adding slot-scope="i" to the tooltip component like <v-tooltip slot-scope="i" right> :

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

})
