Jon, a couple of things about this :

1.- Note, just in case it matters, that the for(var j in records[i])
loop does not specify the order in which the properties of records[i]
are enumerated : you may end up with both firstname,lastname or
lastname,firstname and there is no way to tell in advance what the
order will be.

2.- It's usually a good idea to query the hasOwnProperty method in
order to screen out (unwanted) inherited properties :

for (var j in records[i]) {
 if ( records[i].hasOwnProperty(j) ) {
  str += j + " --> " + records[i][j] + "\n";
 }
}
