That works as expected, thanks.
To add more objects with a variety of URL options in a scene, I simply have to add more lines like this?:
if (obj && obj.name == "Cube")
window.location.href = "http://www.blend4web.com
if (obj && obj.name == "Plane")
window.location.href = "http://www.anotherURL.com
if (obj && obj.name == "Sphere")
window.location.href = "http://www.trepaning.com
Again, for my purposes, if it is a security issue that may make links inoperable in some browsers, I do not need pages to open outside of the domain. Other people may require that, but my focus would not, if that helps with a different bit of coding from your end.
As it is, this is great, but of course to stick with the "no coding required" element of B4W, it would be nice to be able to add the links to objects from the Blender interface.
