java - 当我在 SVG 中将鼠标悬停时，如何显示和隐藏同级元素？

问题描述

我使用了带有两个分区的圆形 SVG 文件，当我将鼠标悬停在选定区域上时，我想显示和隐藏文本。当我鼠标悬停时我确实显示了文本，但是当我隐藏它时它仍然不起作用。我曾尝试只使用 CSS，但它不起作用。

我想要的是首先显示#g0(text)，然后当我将鼠标悬停在每个#g1(area)和#g2(area)上时显示#text-r-1(text)和#text-r-2(text) , 并使 #g0(text) 隐藏。当我将每个#g1（区域）和#g2（区域）鼠标移出时，再次显示#g0（文本）。

很抱歉解释得很好，但我真的需要你的帮助！:o

解决方案

您只能使用 CSS 来做到这一点：您将所有文本的填充不透明度设置为 0。当您将鼠标悬停在组上时，您将内部文本的填充不透明度更改为 1。

您可以添加过渡以获得更漂亮的效果。

text{fill-opacity:0}
g{pointer-events:all;}
g:hover text{fill-opacity:1}
<svg id="circle" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 1142.28 1142.28">
        <g id="g0">
        <text id="text-0" x="50%" y="50%" text-anchor="middle" dy=".3em" font-size="50px" > I want to hide this </text>   
        </g>

        <g id="g1">
        <text id="text-r-1" x="50%" y="50%" text-anchor="middle" stroke="#51c5cf" stroke-width="0px" dy=".3em" font-size="50px"> AAA </text>
        <path id="r-1" d="M747.32,313.17,778.87,361A366.07,366.07,0,0,1,988,295.77V238.46a423.07,423.07,0,0,0-240.68,74.71Z" transform="translate(-416.92 -92.49)" fill="none" stroke="#000" stroke-miterlimit="10"/>
        </g>

        <g id="g2">
        <text id="text-r-2" x="50%" y="50%" text-anchor="middle" stroke="#51c5cf" stroke-width="0px" dy=".3em" font-size="50px"> BBB  </text>

OP正在评论：

鼠标移出 g1 和 g2 时如何显示“g0”？

一种可能的解决方案是将 移到g0svg 元素的末尾并使用~选择器（Subsequent-sibling Combinator）：g:hover ~ #g0 text{fill-opacity:1}

text{fill-opacity:0}
g{pointer-events:all;}
g:hover text{fill-opacity:1}

g:hover ~ #g0 text{fill-opacity:1}
