【问题描述】：

我有两个 svg 图标，我想在 html 中将鼠标指针悬停在另一个图标上，但是我对图标很陌生，有人可以帮忙吗？

我想让鼠标指向白色图标时变成黑色。我正在尝试制作带有链接的“设置图标”；）

我这里有 svg 代码：

    .st2 {

【问题讨论】：

首先你必须将你的图标分成两个不同的svg。完成后，请更新您的问题，我会帮助您。
^ ... 或者，在<defs> 部分中创建两个图标并使用<use> 引用它们，然后根据SVG（或父级）的:hover 状态更改显示哪个图标。跨度>
是的，但是为此目的混合 2 个 svg 并不是最佳做法。我真的不推荐它

标签： html css svg icons

【解决方案1】：

我已将图标放在 defs 元素中。此外，由于元素在绘制它们时在 svg 画布上具有不同的位置，因此我将它们转换回相同的位置。我正在使用带有<use> 元素的第一个图标。接下来，我使用 javascript 来更改 mouseover 和 mouseleaave 上的 xlink:href 的值。希望对你有帮助

const SVG_XLINK = "http://www.w3.org/1999/xlink";

navigation.addEventListener("mouseover",(e)=>{
  elUse.setAttributeNS(SVG_XLINK, 'xlink:href', '#settings_on_1_');
})

navigation.addEventListener("mouseleave",(e)=>{
  elUse.setAttributeNS(SVG_XLINK, 'xlink:href', '#settings_1_');
})

body{background:white;}
svg{border:solid}

【解决方案2】：

您可以只使用一个 svg，然后使用 svg:hover 以及当您将鼠标指向它时希望它显示的颜色。

svg:hover {
  fill: red/black/...;
}

enter link description here

请参考上面的例子，动态传递你的图片！！

<!DOCTYPE html>
<html>
<body>

<img onmouseover="changeImg(this)" id="myImage" onmouseout="normalImg(this)" border="0" src="https://www.w3schools.com/jsref/smiley.gif" alt="Smiley" width="62" height="62">

<p>On Image hover Example</p>

<script>

var image = document.getElementById('myImage');

function changeImg(x) {
  image.src = "https://cdn.pixabay.com/photo/2015/03/04/22/35/head-659652_1280.png";
}

function normalImg(x) {
 image.src = "https://www.w3schools.com/jsref/smiley.gif";
}
</script>

</body>
</html>

请尝试更改为我为 PNG 所做的 SVG。

步骤。

尝试实现 onHover 事件
实现两个函数 onHover 和 normal Function
现在通过使用 document.getElementById('myImage') 获取 Id 将永久图像添加到普通函数
其他图片也一样
