Description
The getLength( ) method returns an integer that

with index numbers from 0

The length is typically used to loop through all records in a recordset, such as:
var myRecordsetLength = myRecordset_rs.getLength( ); for (var i; i < myRecordsetLength; i++) { trace(myRecordset_rs.getItemAt(i)); }
