Html – How to make links in an embedded SVG file open in the main window, not in a separate object

htmlsvg

I have an SVG file (generated by Graphviz) that contains URL links. I would like these links to be clickable. First I tried 

<img src="path/to/my.svg"/>

which displays the image fine but the links are not clickable. Changing to object:

 <object data="/path/to/my.svg" type="image/svg+xml">

makes the links clickable, but when the user clicks on them, the new page opens inside the object. Is there any way that I can make the links open in the main window?

This is using firefox 5.0, but if there are any cross-browser differences you know about I would appreciate the warning!

First, if you embed SVG as <img>, browsers won't open links, as well as they wont run scripts inside <img>, because, well, you embed an image, and very probably your image may appear inside an <a>, and you can't put links inside links.

And to make links open in new tabs, you can use either the target attribute, like in HTML, or xlink-specific xlink:show attribute with the value new. The SVG spec says the following:

[xlink:show] attribute is provided for backwards compatibility with SVG 1.1. It provides documentation to XLink-aware processors. In case of a conflict, the target attribute has priority, since it can express a wider range of values.

And the values of the target attribute can be:

  • _replace
  • _self
  • _parent
  • _top
  • _blank

Thus, in your SVG you need to write as follows:

<a xlink:href="http://example.com" target="_blank">[...]</a>

But currently all browsers capable of showing SVG support both xlink:show and target attributes (I haven't tested in IE9 though).
