You could try something like this... First, create a function that
will process the data values. Then, assign that function to the
ex:href-subcontent. This also works for facets.
Exhibit.FunctionUtilities.registerSimpleMappingFunction(
"myFunction",
function(val) {
if (val == "foo") {
return "../folder1/" + val;
} else if (val == "foo2") {
return "../folder2/" + val";
}
},
"text"
);
ex:href-subcontent="myFunction(.scriptURI)" or
ex:href-subcontent="myFunction({{value}})"
You could probably also pass in multiple values to create your path
information, something like
ex:href-subcontent="myFunction(.scriptURI, .data2)"
Not quite an elegant solution but it seems like it should work in your case.
