Snap没有将我的svg加载到localhost上，这让我疯狂。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
中代码如下：
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档案：
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：

我错过了重要的事情吗？我需要node.js吗？
答案 0 :(得分：1)
如果您正在学习SnapSVG，通常我会使用<svg id="mySVG" ....并避免使用jQuery。这是最简单的示例，让它工作，然后用您的SVG替换myURL。如果您的SVG无法正常工作，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
my_g.attr({id: 'penrose' }); // assign ID for easier access
my_g.add( s.paper.text(10, 20, "Hello Penrose") );
});<script src="https://cdnjs.cloudflare.com/ajax/libs/snap.svg/0.4.1/snap.svg-min.js"></script>
<svg id="svg" width="300" height="300" ></svg>
Sidenote：建议您使用控制台窗口首先测试这些JS代码。
