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
对于一个单独的按钮来说,它似乎工作得很好。
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>
我试过在上面的代码中添加一些东西,比如slot=“activator”添加到v-item,slot scope=“activator”添加到v-btn,但似乎没有什么工作得很好。关于我做错了什么有什么建议吗?
@boussadjarabrahim添加的运行片段:
new Vue({
el: '#app',
data() {
return {
bars: ['a', 'b', 'c']
}
}

最佳答案
在调试代码片段之后,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:
new Vue({
el: '#app',
data() {
return {
bars: ['home', 'event', 'info']
}
}
})
<script src="https://cdn.jsdelivr.net/npm/babel-polyfill/dist/polyfill.min.js"></script>
