缺少默认的范围插槽 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

对于单个按钮似乎可以正常工作.

但是，它在 v-item 中不起作用.我收到一条控制台消息，内容为

<块引用>

'[Vuetify] v-item 缺少默认的 scopedSlot'

<v-工具提示><v-btn slot="激活器"><v-icon>some-icon</v-icon></v-btn><span>一些工具提示文本</span></v-工具提示></v-item>

我已经尝试在上面的代码中添加一些东西，比如将 slot="activator" 添加到 v-item 和将 slot-scope="activator" 添加到 v-btn，但似乎没有任何东西可以正常工作.关于我做错了什么的任何建议?

@BoussadjraBrahim 添加的运行片段:

new Vue({el: '#app',数据() {返回 {酒吧:['a'，'b'，'c']}}})

解决方案

在调试代码片段后，我通过将 slot-scope="i" 添加到 tooltip 找到了解决方案code> 组件，如 :

new Vue({el: '#app',数据() {返回 {酒吧:['家'，'事件'，'信息']}}})

<script src="https://cdn.jsdelivr.net/npm/babel-polyfill/dist/polyfill.min.js"></脚本><script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script><script src="https://cdn.jsdelivr.net/npm/vuetify@1.4.0/dist/vuetify.min.js"></script><link rel="stylesheet" type="text/css" href="https://fonts.googleapis.com/css?family=Roboto:100,300,400,500,700,900|材料+图标"><link rel="stylesheet" type="text/css" href="https://cdn.jsdelivr.net/npm/vuetify@1.4.0/dist/vuetify.min.css"><div id="app" 数据应用程序><v-item-group ><v-container grid-list-md><v-layout wrap><v-flex v-for="(n,i) in bar" :key="n" xs12 md4><v-item ><v-tooltip slot-scope="i" right><v-btn slot="激活器"><v-icon>{{n}}</v-icon></v-btn><span>{{n}}</span></v-工具提示></v-item></v-flex></v-layout></v-容器></v-item-group>

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

It seems to work fine for an individual button.

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

'[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>

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?

Running snippet added by @BoussadjraBrahim :

      bars: ['a', 'b', 'c']
    }

              </v-btn>
              <span>Some tooltip text {{n}}</span>
            </v-tooltip>
          </v-item>
        </v-flex>
      </v-layout>
    </v-container>
  </v-item-group>

</div>

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']
    }
  }

})

<div id="app" data-app>

    <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>
