Get list of data-* attributes using javascript / jQuery
...jQuery's attempt at "deserializing" the value found in the attribute (i.e. from master: !jQuery.isNaN( data ) ? parseFloat( data ) : ...). I had product serial numbers in my attribute such as data-serial="00071134" which jQuery munged into a number 71134, forcing me to revert to the less elegant .at...
