If window.location.port is empty that means the application is running on port 80 for http and 443 for https.

As mentioned in a comment, you can use window.location.protocol to check what protocol is used (http or https).

Implementation:

function getPort(){
  if(location.port != ''){
      return location.port;
  }
  else if(location.protocol== 'http'){
     return 80;    
  }
  else if(location.protocol== 'https'){
     return 443;    
  }    
}
