最近，在我在线阅读了一个非常有趣的教程后，我能够对 svg 文件进行动画处理:https://jakearchibald.com/2013/animated-line-drawing-svg/ .
现在的问题是我必须切换到另一种类型的 svg，我猜是新版本。
到目前为止我的代码是:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">

</svg>
以及我添加的 JavaScript 代码段:
$('.snap').eq(0).one("mouseenter", function() {
var path = document.querySelector('.snap path');
path.getTotalLength();
var path = document.querySelector('.snap path');
var length = path.getTotalLength();
path.style.transition = path.style.WebkitTransition =
'none';
path.style.strokeDasharray = length + ' ' + length;
path.style.strokeDashoffset = length;
path.getBoundingClientRect();
path.style.transition = path.style.WebkitTransition =
'stroke-dashoffset 2s ease-in-out';
path.style.strokeDashoffset = '0';
});
我用过eq(0)因为我使用了多个 svg 文件。
但现在的问题是我必须使用这样的文件:
<?xml version="1.0" encoding="utf-8"?>
<!-- Generator: Adobe Illustrator 19.2.1, SVG Export Plug-In . SVG Version: 6.00 Build 0) -->
<svg class="snap" version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" viewBox="0 0 106.2 107" style="enable-background:new 0 0 106.2 107;" xml:space="preserve">
<style type="text/css">
.st0 {
fill: none;
stroke: #8DC63F;
stroke-width: 2;
stroke-linecap: round;
stroke-linejoin: round;
stroke-miterlimit: 10;
}
</style>
<g>
<ellipse transform="matrix(0.7071 -0.7071 0.7071 0.7071 -22.2988 53.1541)" class="st0" cx="53" cy="53.5" rx="38.1" ry="38.1" />
<g>
<path class="st0" d="M30,37c-2,13.7-3.5,26.8,13.2,28C49.3,55,49.3,46.2,30,37z" />

<path class="st0" d="M70.7,45C66,49.4,58.9,59.3,56.2,72.2" />
</g>
</g>
</svg>
我尝试选择路径，但效果仅适用于第一个路径，我使用了 querySelectorAll ，但我收到错误 -> getTotalLength() 。所以我决定选择<g>元素，但无论如何它都不起作用。
有什么建议吗？
更新:
由于性能问题，我将 svg 内联元素切换为对象元素。我现在正在使用这样的文件代码:

我添加了一段实际有效的代码，但我无法使用 jQuery 的每个函数迭代所有图像(我尝试了一些方法，但它们不起作用)。另外，我无法与不同于路径元素的其他元素进行交互，也无法将它们转换为路径元素。
到目前为止我的代码是:
$('.snap').eq(0).one("mouseenter", function() {
var path_all = document.querySelectorAll('.snap path');
$.each(path_all, function(key, path) {
var length = path.getTotalLength();
path.style.transition = path.style.WebkitTransition =
'none';
path.style.strokeDasharray = length + ' ' + length;
path.style.strokeDashoffset = length;
path.getBoundingClientRect();
path.style.transition = path.style.WebkitTransition =
'stroke-dashoffset 2s ease-in-out';
path.style.strokeDashoffset = '0';
});
});
$('.snap').eq(1).one("mouseenter", function() {
var path_all = document.querySelectorAll('.snap path');
$.each(path_all, function(key, path) {
var length = path.getTotalLength();
path.style.transition = path.style.WebkitTransition =
'none';
path.style.strokeDasharray = length + ' ' + length;
path.style.strokeDashoffset = length;
path.getBoundingClientRect();
path.style.transition = path.style.WebkitTransition =
'stroke-dashoffset 2s ease-in-out';
path.style.strokeDashoffset = '0';
});
});
$('.snap').eq(2).one("mouseenter", function() {
var path_all = document.querySelectorAll('.snap path');
$.each(path_all, function(key, path) {
var length = path.getTotalLength();
path.style.transition = path.style.WebkitTransition =
'none';
path.style.strokeDasharray = length + ' ' + length;
path.style.strokeDashoffset = length;
path.getBoundingClientRect();
path.style.transition = path.style.WebkitTransition =
'stroke-dashoffset 2s ease-in-out';
path.style.strokeDashoffset = '0';
});
});
$('.snap').eq(3).one("mouseenter", function() {
var path_all = document.querySelectorAll('.snap path');
$.each(path_all, function(key, path) {
var length = path.getTotalLength();
path.style.transition = path.style.WebkitTransition =

path.style.strokeDasharray = length + ' ' + length;
path.style.strokeDashoffset = length;
path.getBoundingClientRect();
path.style.transition = path.style.WebkitTransition =
'stroke-dashoffset 2s ease-in-out';
path.style.strokeDashoffset = '0';
});
});
关于如何处理这个主题有什么建议吗？
最佳答案
您几乎就到了，解决方案是使用document.querySelectorAll并循环遍历所有路径。请参阅下面的演示:-
$('.snap').eq(0).one("mouseenter", function() {
var path_all = document.querySelectorAll('.snap path');
$.each(path_all, function(key, path) {
var length = path.getTotalLength();
path.style.transition = path.style.WebkitTransition =
'none';
path.style.strokeDasharray = length + ' ' + length;
path.style.strokeDashoffset = length;
path.getBoundingClientRect();
path.style.transition = path.style.WebkitTransition =
'stroke-dashoffset 2s ease-in-out';
path.style.strokeDashoffset = '0';
});
