Snap 没有在本地主机上加载我的 svg，这让我抓狂。我有一个使用 Apache 和 PHP 设置的基本服务器。

index.html 和 css、js 和 svg 文件夹位于 C:\Apache24\htdocs

代码如下:

HTML 文件:

<!doctype html>

<head>
    <link rel="stylesheet" type="text/css" href="style.css">
    <script src="js/snap.svg-min.js"></script>
    <script src="js/main.js"></script>
</head>

<body>
    <svg class="map_canvas"></svg>
</body>

CSS 文件:

.map_canvas {
width: 600px;
height: 800px;
}

JS文件:

var s = Snap($(".map_canvas")[0]);

var g = s.paper.g();

Snap.load("svg/map.svg", onLoadSvg);

function onLoadSvg(doc) {
    g.add( doc );
    g.add( s.paper.text(200, 200, "Hello World") );
}

svg:

我错过了什么重要的事情吗？我需要 Node.js 吗？

最佳答案

通常我会使用<svg id="mySVG" ....如果您正在学习 SnapSVG，请避免使用 jQuery。这是最简单的例子，让它工作然后替换 myURL用你的SVG。如果您的 SVG 无法工作，则可能是 Apache 问题(您从 http://localhost 运行，而不是直接从 HDD 运行？)

var s = Snap("#svg");
var myURL = "https://upload.wikimedia.org/wikipedia/commons/f/f4/Penrose_triangle.svg";

Snap.load(myURL, function(frag) { // returns fragment
    var my_g = s.g();  // create new group
    my_g.append(frag); // append fragment
