VueJS将鼠标悬停在for循环中 [英] VueJS mouseover in for loop

问题描述

我有一个for，它将为每个索引创建一个组件.

I have a for that will create a component for each index.

在此组件中，我有一个子div，其中包含编辑，添加，减号按钮. 我希望它显示在组件鼠标悬停上.

In this component, I have a child div containing edit, add, minus buttons. I would like it to be displayed on the component mouseover.

我如何动态地做到这一点而不必使用索引?

How do I achieve this dynamically without having to play with indexes ?

谢谢.

推荐答案

Post组件

<template>
  <div v-on:mouseleave.native="showOperations = false"
       v-on:mouseover.native="showOperations = true">
    <!-- post data -->
    <div v-if="showOperations">
      <!-- operations -->
    </div>
  </div>
</template>

<script>
export default {
  ...
  data () {
    return {
      showOperations: false
    }
  },
  ...
</script>

帖子列表

<post v-for="post in posts"
      :key="post.id"
      :post="post">
</post>

此模式对我有用，我认为它也对您有用

This pattern works for me and I think it works for you as well
