Answer 1

Remove the preceded + from alert and try,

alert(actualadddate + 'aaaaaaaaa');

Live working demo

Note that, in your example you are using .date class to access the attribute if your page has more than 1 element having same class then it will not give you the accurate date. So, be carefull in that case or use unique id to get the attribute.

Answer 2

Remove + operator from beginning. Use:

alert(actualadddate+"aaaaaaaaa");
