Question

Is it possible to enable popup with not only country name but some additional text (for example, address, telephone) with JVectorMap?

Answer 1

Yes, you bind handler for onRegionLabelShow event. The second parameter passed to the callback will be label jQuery element. See documentation. Example:

onRegionLabelShow: function(e, label, code){
  label.html(label.html()+' (GDP - '+gdpData[code]+')');
}
