JSP :: Change Color Of HTML Table Row In A Page

I am creating a JSP page with a html table to display employee directory. This is scriptlet :

<%
List<Employee> list = new ArrayList<Employee>();
PhoneListController controller = new PhoneListController();
list = controller.getAllContacts();
for (Employee eachEmp : list) {
%>

and then i display the table rows and columns for each employee object(PS: I know scriptlets are bad and obsolete but this is my first individual project.)

I would like to change the background color of certain rows based on value of one particular value(based on eachEmp.getManagerCode).

How can i achieve that by using javascript? I tried to call a js function by calling onload event on . But as I need to check for each row that is not the possible solution. I have not tried jquery yet as I am very new to jquery and I didnt quite understand how to do it in jquery.
