我正在创建一个使用嵌入式浏览器显示SVG文件的软件(带有SVG的HTML / HTML5)。
许多SVG文件会有很多共同点,所以我希望避免将该部分复制到所有SVG文件中。我想提供一个扩展/包含的基本SVG。让我们调用基础SVG" base.svg"。
我在SVG中搜索了类似INCLUDE的内容,但它并不存在。
是否可以创建一个包含HTML5链接元素的HTML文件,或者包含base.svg的javascript代码? 然后,我只是将其余的SVG放入HTML中。像这样(伪):
<html>
<body>
<link rel="import" href="base.svg" />
<!-- or some javascript code to include the base.svg content -->
<svg>
<!-- The rest of the SVG -->
</svg>
</body>
</html>
有可能吗? 如果没有,使用PHP服务器(或类似的东西)动态生成完整的SVG(result = base.svg + rest.svg)是不错的选择?
非常感谢。

Load svg files as XML via <b>XMLHttpRequest</b>. Parse the Document Elements to create a client's file.
This example first loads the <b>Base.svg</b> inline into a DIV, then extracts/adds elements from another <b>companion</b> svg file,
combining them into a seamless svg root.

要加载它,您应该打开以下网址:
http://theHTMLfile?svg=companion.svg&destination=childSVG
Ps:我知道图像蒙版的坐标不能很好地工作。忽略这一点。这只是一个考验。 干杯!
答案 0 :(得分:2)
我假设您可以访问XML DOM。如果是这样,合并svg的最佳方法是通过xml dom方法。
EDIT (added below) UPDATE: added xlink namespace, needed for image elements
以下是将svg文件合并到客户端上的单个内联svg的非常基本的方法。它可以通过XML DOM组合/解析SVG文件。
通过XMLHttpRequest
将svg文件作为XML加载。解析文档元素以创建客户端文件。
此示例首先将 Base.svg 内联加载到DIV中,然后从另一个 companion.svg 文件中提取/添加元素,
将它们组合成一个无缝的svg根。
