Adding Dynamic rows(group of html controls).

Question

Hi!
I need to add group of HTML fields i.e., textboxes,dropdown, radio buttions by clicking a button on to the existing JSP Page.
The sample page as "http://www.rj2t.com/test/deca/advisors/sec_form.asp". I also need to accept the data and print them to another JSP from these dynamically generated fields.
Please help.!!!!

Answer 1

The sample page you provided reloads when the rows are requested.
This posts a number in the <textfield name="examplename"> field, the method being POST (there is no query string). The form target in the sample page is itself. When it loads with no 'examplename' parameter passed to it, 20 rows are outputed, then it reloads itself with the value given in the textfield when the submit ("Generate Lines") button is clicked
The JSP would then use a loop such as
int numberOfRows=20;
try{numberOfRows=Integer.parseInt(HttpServletRequest.getParameter("examplename")}
catch (NumberFormatException exc){}//this is one of the few circumstances where the exception can be
                //consumed as the variable is still 20 if the 'examplename' parameter is null or unparsable;
for (int loop=0 ; loop<numberOfRows ; loop++)
  //the HTML for a single row of form fields goes here;
}
