我在 Illustrator 中重新创建了这个形状,所以它不是很完美,但非常接近。然后我将其保存为 SVG 路径。
这是执行我认为您想要的工作的代码。
SVG 形状:
<?xml version="1.0" encoding="utf-8"?>
<svg id="myshape" 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 0 571.1 437.5" style="enable-background:new 0 0 571.1 437.5;" xml:space="preserve" stroke="#000" stroke-width="90" stroke-miterlimit="10">
<g>

</g>
</svg>
JavaScript
drawTime = 2000; //2 seconds
path = document.getElementById("mypath");
length = path.getTotalLength();
path.style.strokeDashoffset = length; //starting position
path.style.strokeDasharray = length + ', ' + length;
path.style.fill = "none"; //make it have no fill to begin with
path.style.transition = path.style.WebkitTransition = 'none';
path.getBoundingClientRect();
path.style.transition = path.style.WebkitTransition = 'stroke-dashoffset ' + (drawTime / 1000) + 's ease-in-out';
path.style.strokeDashoffset = '0'; //finishing position

JSFiddle(用我写的 jQuery 插件):https://jsfiddle.net/vL5bz5mn/1/
对于 jQuery... 我大约一年前为 jQuery 1.10 或类似的东西编写了 DrawSVG 插件。我希望这有帮助!如果你愿意,你可以只使用 JavaScript。
