You could use an array/object to hold all of your fields:
var field_array = [];
for(var i=1; i<=total_field_sets; i++){
...
var field = new ftmDataEntryTextfield(...);
if(i<=25){
...
field.setLeft(left_col_booking_ref_x);
splitpane.addLeft(..., field,...);
} else {
...
field.setLeft(right_col_booking_ref_x);
splitpane.addRight(..., field,...);
}
var field_name = "booking_ref_" + i;
field_array[field_name] = field;
}
...
for(var i=1; i<=total_field_sets; i++){
// reconstruct the field name:
var field_name = "booking_ref" + i;
// look up the field from the array:
var field = field_array[field_name];
// access data in the field:
field.setValue( ... );
}
and so on. You get the idea. This can then be extended to sets of
arrays for labels, fields, attributes, etc.
