I have a requirement with select and text boxes. JSP / JDBC

Question

I have a Combo Box which iswritten by a JSP by connecting to DB!
When i click on a <option> corresponding the other two text boxes must be loaded with data!
if i have list of EmpID in <select>, in one text box i should get his CITY and other Occupation !
What i thought is .... getting all the data from database. select empid from emp and write a combo and select city,occupation from emp, intp ARRAYLISTs!
function updatData(){
var index=document.projalloc.associateid.selectedIndex;
}if i onSelect=updateData(), (i will get index of empid,as it is a combobox) using which i have to retrieve the values of city and occupation !!
BUT HOW !
I am gettin the index of empid but how to get the data into textbox !!!!

Answer 1

well there are many ways of doing this.
1).Render all the data corresponding to each employee at a time.By making a javascript arrays and try to get back the data from there.
2).Save the ArrayList of DTO beans in the scope of session.Use AJAX call a CGI(Servlet/JSP action) fetch the values from the session render the response as XML now parse the XML data using javascript DOM and then update the consecutive textboxes.
Just as an example checkout my answer in the below post.It was an example given for a dependent drop downs.however, we can definately use the same concept to update textboxes too.
