html - postback to server executing different queries -

i have few <div> inside forms, each thing inside div contains specific form. when user presses submit button, want execute different action based on

<form method="get" action="addprogramtodb.jsp"> <select name="cid"  style="display: none;"> <option>1</option> <option>2</option> </select>  <div id="1"> </div>  <div id="2"> </div>  <div id="3"> </div>  <input type="submit"/> </form> 

when user presses submit button want program execute different queries based on div in.... based on div id, or somehow..

give submit button name , value usual way.

<input type="submit" name="action" value="action1"> ... <input type="submit" name="action" value="action2"> ... <input type="submit" name="action" value="action3"> 

the pressed button namely available request parameter well.

string action = request.getparameter("action");  if ("action1".equals(action)) {     // action1 button pressed. } else ("action2".equals(action)) {     // action2 button pressed. } else ("action3".equals(action)) {     // action3 button pressed. }

you can if necessary give them different name instead , nullcheck each request parameter.

<input type="submit" name="action1" value="this more i18n friendly"> ... <input type="submit" name="action2" value="blah"> ... <input type="submit" name="action3" value="more blah"> 

with

if (request.getparameter("action1") != null) {     // action1 button pressed. } else (request.getparameter("action2") != null) {     // action2 button pressed. } else (request.getparameter("action3") != null) {     // action3 button pressed. }

or, if in their own <form>, can pass hidden input along.

<form>      <input type="hidden" name="action" value="action1">     ... </form> <form>      <input type="hidden" name="action" value="action2">     ... </form> <form>      <input type="hidden" name="action" value="action3">     ... </form> 

with same server-side handling in 1st example.
