我遇到了这个问题，我需要在 SVG 图像之间顺利切换。我需要从中得到:

Normal

为此:

Hover

我试过改变填充，但它只改变了描边。这可以通过 JS/jQuery 或任何其他方式实现吗？

谢谢。

最佳答案

你可以用 css 做到这一点。根本不需要任何脚本。

这段代码可以做到。基本上，img1.svg 是您显示的顶部图像，img2.svg 是底部图像。当鼠标悬停在包含的 div (#crossfade) 上时，其中一个图像 (img1) 从不透明变为透明，另一个图像 (img2) 从透明变为不透明。

注意事项:

  • 在我的测试中，第一张图片是完全透明的，除了中风。第二张图片完全不透明，除了区域在“广场”之外
  • 我懒得运行 SVG 清洁器或其他类似的东西，因此小数点后的多位数字。 (例如笔画宽度:2.93599999999999990)

我从这里得到代码:http://www.cssreset.com/how-to-create-the-perfect-image-crossfade-with-css3-transitions/

HTML

<!DOCTYPE html>
<html>
<head>
<style>
#crossfade {
    position:relative;
    width: 93px;
    height: 93px;
}


#crossfade img.top {
    opacity:    1;
}

#crossfade img.bottom {
    opacity:    0;
}

#crossfade img {
    position:absolute;
    left:0;
    -webkit-transition: opacity 0.2s ease-in-out;
    -moz-transition: opacity 0.2s ease-in-out;
    -o-transition: opacity 0.2s ease-in-out;
    -ms-transition: opacity 0.2s ease-in-out;    
    transition: opacity 0.2s ease-in-out;
}

#crossfade:hover img.top {
    opacity:0;
}

#crossfade:hover img.bottom {
    opacity:1;
}

</style>
</head>
<body>
    <div id="crossfade">
        <img class="bottom" src="img2.svg" />
        <img class="top" src="img1.svg" />
    </div>
</body>
