Workaround to pass javascript value to jsp...

[chichu9]

Hi,

I would like to find out how to do the following workaround.

I retrieve the value from database using a javabean and return this to
jsp page and display the data using html/javascript dropdown listbox.

I will need to use the selected value from user and pass this value to
javabean to retrieve another value to be displayed on the same
page/form basically achieving the drilldown effect.

I would prefer not to do a form post everytime the user selects the
value unless it is the ONLY option.

Pls help.

Key words: "value from the user". If you need to present the page to a
user and then perform some action based on the user's subsequent
behavior then there is no escaping a second round trip to the server.
There are ways to make the second round trip less obvious to the user
(that's a key part of what "AJAX" is about), but you can't avoid it
altogether.
