 <meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
 <script language="javascript">
window.onload = function(){
    //获得SVG文档的DOM结构
     var svgdoc = document.getElementById("id1").getSVGDocument();
}
 </script>
 </head>
 <body>
 
 <!-- 插入SVG文档 -->
 <embed id="id1" pluginspage="http://www.adobe.com/svg/viewer/install/" src="a.svg" height="200px" width="400px" type="image/svg+xml">
 
</body>
</html>

<svg xmlns="http://www.w3.org/2000/svg"
width="3.5in" height="1in">
<title>Listing 24-1 from the XML Bible</title>
<script type="text/javascript">
<![CDATA[
alert(123);
]]>
</script>
<circle r="30" cx="34" cy="34"
style="fill: red; stroke: blue; stroke-width: 2" />
</svg>

<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink"
width="3.5in" height="1in">
<title>Listing 24-1 from the XML Bible</title>
<circle id="x" r="30" cx="34" cy="34"
style="fill: red; stroke: blue; stroke-width: 2" />
<script type="text/javascript" xlink:href="a.js">
</script>
</svg>

注意的是需要添加命名空间xmlns:xlink="http://www.w3.org/1999/xlink"，不然解析script节点的xlink:href="a.js"属性会报错
