【中文标题】当我在 SVG 中将鼠标悬停时,如何显示和隐藏同级元素?【英文标题】:How can I show and hide sibling element when I mouse over in SVG? 【发布时间】:2021-05-15 01:12:38 【问题描述】:

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

【问题讨论】:

有 ID 时为什么要使用 siblings() 老实说,我不知道为什么要使用它。我对javascript一无所知,但是在看到上面的堆栈溢出中的javascript后,我尝试使用它:o 【参考方案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#g2

这是一个快速的工作方式:

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

【讨论】:

非常感谢!!这就是我想要的:)【参考方案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。

textfill-opacity:0
gpointer-events:all;

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 textfill-opacity:1

textfill-opacity:0
gpointer-events:all;
g:hover textfill-opacity:1

g:hover ~ #g0 textfill-opacity:1

【讨论】:

谢谢!但是,当我将 g1 和 g2 鼠标移出时,如何显示“g0”?因为如果我按照你教的那样使用 css,g0 将被隐藏。【参考方案3】:

$( "#g1").hover(function() 
  $(this).prevAll().slice(0, 1).addClass('hhh');
, function() 
        $(this).prevAll().slice(0, 1).removeClass("hhh");
    );
    
$("#g2").hover(function() 
  $(this).prev().prevAll().slice(0, 2).addClass('hhh');
, function() 
        $(this).prevAll().slice(0, 2).removeClass("hhh");
    );
