Question

var currentClassName = $(this).parent('td').next('td').find('input:text').attr('class'); if (currentClassName == undefined) { currentClassName = $(this).parent('td').find('input:text').attr('class'); } This works, but i suppose it can be written in one row? Im not really satisfied with this solution.
