If he's willing to reload the page when the user clicks go, then no ajax
required.
Enclose your <select> tags in a form. Name the first one "department".
Make the go button an <input type="submit"> tag. At the top of your
page, add a snippet of java:
<%
String department = request.getParameter("department");
if (department == null) {
// select the entire table here} else {
// select the table where the dept field = the department param
}
// deal with section here
%>
thanks for the reply.
but i need something different.
complete flow is like this .
i am giving cases here.
(1) select [none] + select [none] ---->go ---> Shows All records
(2)select [ value1] + select[none] --->go ---->shows only those
records which has the match with value1
(3)select [ none] + select[value 2] --->go ---->shows only those
records which has the match with value2
(4)loading the page first time ---> shows all records .
I already have written the code and it became complex . i used
session ...and some how things has been messed up.
so, looking for a better suggestion in terms of logic .
i need a better logic.
i used so many if-else's but unfortunately at the run time these four
cases are not satisfied properly.
Anyway, can you tell me some proper logic as i am revisiting /
reviewing my code.
thanks
