what do you mean by select/dropdown ?

here is an example

hi
here i will give one example:
suppose you are getting three value from database- val1, val2, val3
you want to make a list box out of this then you need to return a list box from server side.
now form a string like this:
you should write System.ont.println() only once.
-idea is that whatever you will return from server, you will get from
you can do same for table also.
i hope this will help you.
Have a nice time !

you should write System.ont.println() only once.
-idea is that whatever you will return from server, you will get from
xmlHttp.responseText at client side in ajax.you can do same for table also.
i hope this will help you.
Have a nice time !
