一、在HTMl中访问SVG的DOM：
1 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
2 <html xmlns="http://www.w3.org/1999/xhtml">
3 <head>
4 <meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
5 <script language="javascript">
6 window.onload = function(){
7 //获得SVG文档的DOM结构
8 var svgdoc = document.getElementById("id1").getSVGDocument();
9 }
10 </script>
11 </head>
12 <body>
13
14 <!-- 插入SVG文档 -->
15 <embed id="id1" pluginspage="http://www.adobe.com/svg/viewer/install/" src="a.svg" height="200px" width="400px" type="image/svg+xml">
16
17 </body>
18 </html>
2 <html xmlns="http://www.w3.org/1999/xhtml">
3 <head>
4 <meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
5 <script language="javascript">
6 window.onload = function(){
7 //获得SVG文档的DOM结构
8 var svgdoc = document.getElementById("id1").getSVGDocument();
9 }
10 </script>
11 </head>
12 <body>
13
14 <!-- 插入SVG文档 -->
15 <embed id="id1" pluginspage="http://www.adobe.com/svg/viewer/install/" src="a.svg" height="200px" width="400px" type="image/svg+xml">
16
17 </body>
18 </html>
二、在SVG文档中嵌入JavaScript：
1 <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
2 <svg xmlns="http://www.w3.org/2000/svg"
3 width="3.5in" height="1in">
4 <title>Listing 24-1 from the XML Bible</title>
5 <script type="text/javascript">
6 <![CDATA[
7 alert(123);
8 ]]>
9 </script>
10 <circle r="30" cx="34" cy="34"
11 style="fill: red; stroke: blue; stroke- 2" />
12 </svg>
2 <svg xmlns="http://www.w3.org/2000/svg"
3 width="3.5in" height="1in">
4 <title>Listing 24-1 from the XML Bible</title>
5 <script type="text/javascript">
6 <![CDATA[
7 alert(123);
8 ]]>
9 </script>
10 <circle r="30" cx="34" cy="34"
11 style="fill: red; stroke: blue; stroke- 2" />
12 </svg>
三、在SVG文档中链接外部JavaScript：
1 <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
2 <svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink"
3 width="3.5in" height="1in">
4 <title>Listing 24-1 from the XML Bible</title>
5 <circle id="x" r="30" cx="34" cy="34"
6 style="fill: red; stroke: blue; stroke- 2" />
7 <script type="text/javascript" xlink:href="a.js">
8 </script>
9 </svg>
2 <svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink"
3 width="3.5in" height="1in">
4 <title>Listing 24-1 from the XML Bible</title>
5 <circle id="x" r="30" cx="34" cy="34"
6 style="fill: red; stroke: blue; stroke- 2" />
7 <script type="text/javascript" xlink:href="a.js">
8 </script>
9 </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
