In jQuery we use the selector for select any elements, and we have to put . for the class and # to the id selector so please put # or . before your element.

In your case, $('#Hid_BasicSalary'); or $('.Hid_BasicSalary'); is your answer.

you missed the "#" and i think that you should use the hidden control's clientid.

var BasicSalary = $('#<%=Hid_BasicSalary.ClientID%>');
