When you have a form where there are multiple group roles, you can select multiple sub-groups for a role using the .indexOf method in your rule.
Example:
Check to see if user has "oit_security_frevvo_exit_" in it:
Rule Code:
var x;
if (form.load) {
// User Information
var roles = _data.getParameter ("subject.roles");
if (roles) {
eval ('x=' + roles);
for(var i =0; i<x.length; i++){
if(x[i].indexOf("oit_security_frevvo_exit_") > -1){
//This user role starts with oit_security_frevvo_exit_
frevvo.log(x[i]);
}
}
}
}
