Hi guyz.
I have a huge prob. It may look simple to you guyz. Its hard for me because I am using ajax which I am not aware of. Please guide me a little.

I dynamically added few elements. In those one is chekbox, a textfield and two select's. One select is loaded based on selection of first. Till here its fine. The problem is when i add next row of same elements and try to change the value of newly added element, the first select(2) values changes. Which should only change when I change the select of first select only. I would also like to know how can I retrieve the values of these dynamically created elements with jsp. The Ajax and my HTML code is given below.

Index.jsp




item.jsp (this is used to populate based on selected value)



Hope I am clear and looking for anyone's reply on this issue.
Ajax is like alien language



Thanks and Regards
Adeeb.

Posting server-side JSP code isn't very helpful to solve JavaScript questions.

Please pare the code down to an SSCCE that shows the problem with no server-side JSP code.

I'd also adopt jQuery to do the Ajax for you. Much simpler.
