Vue JS - 如何更改鼠标悬停时显示的组件的位置

【中文标题】Vue JS - 如何更改鼠标悬停时显示的组件的位置

【英文标题】：Vue JS - How to change the position of a component that is displayed on mouse hover

【发布时间】：2021-07-25 06:34:50

【问题描述】：

我有一个与组件位置有关的问题。我有四张图片，当你将鼠标悬停在它们上面时，会显示某个组件，它看起来像这样

例如，如果将鼠标光标悬停在黄色图片上，则下方会显示另一个组件，以此类推所有组件

我的问题是当屏幕达到568像素时，即移动版，因为我需要改变显示组件的位置，因为此刻在移动版中我应该显示的组件看起来像这样

注意所有组件都显示在底部，我需要它们显示在我的每张图片的底部

也就是说，我希望它们看起来像这样。

可以看到给定的code in codesandbox

App.vue

    <div class="enjoy_headline_container">
      <div class="EnjoyGirlsContainer">

【参考方案1】：

有上百万种方法可以做到这一点。实现您想要的一种简单方法是将信息同时包含在“两个”位置，并使用 CSS 媒体查询控制其外观。见这里：https://developer.mozilla.org/en-US/docs/Web/CSS/Media_Queries/Using_media_queries

所以基本上它看起来像这样

<Cougars>
 <EnjoyRed class="next-to-description" />
</Cougars>
<MINXES>
 <EnjoyGreen class="next-to-description" />
</MINXES>
<MILFS>
 <EnjoyYellow class="next-to-description" />
</MILFS>

<component :is="enjoy.componentName" class="below-all-description" />

然后设置一些css，例如：

.next-to-description 
  display: block;


.below-all-description 
  display: none;


@media screen and (min-width: 568px) 
  .next-to-description 
    display: none;
  
  .below-all-description 
    display: block;
  

现在您只需要确保每当<Cougars> 获得mouseover 事件时，您使用v-if 或其他内容填充EnjoyRed 组件，并继续使用<component :is="..">

CSS 将控制并确保一次只显示 1 个。

我在 jsfiddle 上添加了我的想法的准系统示例：

【讨论】：

非常感谢您关注我的问题，您无法在代码框中显示此示例，我在问题上留下了链接

我添加了一个 js fiddle 来简化代码，这样您就可以专注于必要的更改。另请注意，我的媒体查询中有一个错字 - 它应该是 min-width

非常感谢您一直以来的支持。
