当我在 SVG 中将鼠标悬停时，如何显示和隐藏同级元素？

Question

我使用了 SVG 文件，它是带有两个分割的圆形，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。

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

很抱歉解释得很好，但我真的需要你的帮助！ :o

Answer 1

首先，你使用 jQuery 语法而不在你的项目中绑定它——所以它不能工作。

其次，您的 JavaScript 不需要两个 $( document ).ready()，只需使用一次即可。

第三，您可以在一个选择器中同时选择#g1 和#g2。

这是一个快速的工作方式：

$(function() {
  $("#g1, #g2").hover(function() {
    $("#g0").addClass("hhh");
  }, function() {
    $("#g0").removeClass("hhh");
  });
});

svg {

  fill: #FF313F;
  transition: all 0.5s;
}

path#r-2 {
  fill: #EBA7A7;
  transition: all 0.5s;
}

svg #text-r-1 {
  display: none;
}

svg #g1:hover #text-r-1 {
  display: block;
}

svg #g1:hover path#r-1 {
  fill: #383838;
}

svg #text-r-2 {
  display: none;
}

svg #g2:hover #text-r-2 {
  display: block;
}

svg #g2:hover path#r-2 {
  fill: #383838;
}

.hhh {

Answer 2

您只能使用 CSS 来实现：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，您会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}

        </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>

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g0 移动到svg 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}
