Hi
I need to refer to *all* the values of a combobox in one page across the
session.
i can get the selected value by Request.getParameter("comboname");
how can i refer to all the values?
Eg. I have
1 2
more values are added to the form dynamically
in get.jsp i want to be able to read
Why can you not use request.getParameter() in a declaration?
More specific, how are you supposed to write a method that can check the
values of a form input. Say I want a method called checkValues() that validates
the user input to the form, and outputs which fields are invalid.
Any hel

Request.getParameter("comboname"); returns only the selected value

If none of the values in the combo box are selected, this returns null
<%=request.getParameterValues("cbyoursel")%> , is the code i tried for a
cbbox cbyoursel which is populated with values but

thanks for the help everybody,
finally i looped through the combo, concatednated the values and passed
them by putting in a hidden input field. On the other side, i used the
string tokenizer to read the values and display accordingly
thanks again

Thanks for the explanation Phil,
I managed to transfer the values of the combo to another jsp page.

As I said... use request.getParameterValues("comboname"), that returns an
array of values and should return all of the selected
If yoiu want your function to access request object you should pass it as a
parameter ...
