create new date object return current time , date , individual parameter of date.

date object return hours, minutes , seconds without leading 0 make sure add because values set in select leading 0 , month start 0 current month required + 1.

var currentdate = new date();  $('[name=date_d]').val(currentdate.getdate());  $('[name=date_m]').val(currentdate.getmonth() + 1);  $('[name=date_y]').val(currentdate.getfullyear());  $('[name=time_h]').val(currentdate.gethours() < 10 ? '0' + currentdate.gethours() : currentdate.gethours());  $('[name=time_m]').val(currentdate.getminutes() < 10 ? '0' + currentdate.getminutes() : currentdate.getminutes());  $('[name=time_s]').val(currentdate.getseconds() < 10 ? '0' + currentdate.getseconds() : currentdate.getseconds());
