You can also use pguid (page-unique identifier) for unique identifier generation:

 pguid = b9j.pguid.next() // A unique id (suitable for a DOM element)
                          // is generated
                          // Something like "b9j-pguid-20a9ff-0"
 ...
 pguid = b9j.pguid.next() // Another unique one... "b9j-pguid-20a9ff-1"

 // Build a custom generator
 var sequence = new b9j.pguid.Sequence({ namespace: "frobozz" })
 pguid = sequence.next() "frobozz-c861e1-0"
