Row identifier in jQuery

Row identifier in jQuery

Can we access a row of a table only if it's updated by jQuery?

A table is rendered to JSP UI. The table has data and approved combo box with yes/No values at each row. So each row in the table may or may not be updated. Only if a row is updated then that particular row is identified and will be sent to update to database through a hibernate session. Can we access each row of a table in jQuery in any way ?
