Calling an action class through Javascript -Struts 2.
Hi All ,
I'm trying to call an action class , On change of the values in a dropdown
box in my jsp .I also have to pass a value to the action class to execute
the method . Im trying to implement it only using Javascript as part of our
project requirements , and so using AJAX with JSON , dwr etc is ruled out .
If anyone could provide pointers of its implementation using Javascript it
would be great.

Make it easier to the point of it being a Really Bad Idea to do it
*without* them.
Use one.

if you don't use AJAX then you can only do the standard get/post based on form submission which is a synchronous call.
you can use AJAX functionality straight from plain old javascript without using DOJO or other javascript libraries - its just those libs make it easier.

I would highly recommend AJAX/JSON/jQuery, they are Javascript.
Question -
Does your requirement state that the data should be server-call back
delay delivered?
Does your requirement expect the data to be pre-rendered and the DOM
updated real-time?
Either way, I would use jQuery to perform either of the tasks. In the
case of the first, I would have jQuery do an AJAX call back to the
server, and upon success, iterate the JSON result and update the DOM
accordingly. In the case of the later, I'd embed the data in hidden
DIVs and then upon the change event, I'd use jQuery to iterate over my
hidden DIVs and retrieve the embedded data and then update the DOM
similarly to that of the AJAX call.

we just use js ajax request the json data from struts2 action. you can
find a jsonlib from json.org, written by java,it's quite easy... good

Both Ajax and JSON are JavaScript.
