assuming cancelrequest servlet defined in web.xml as:
<servlet> <servlet-name>cancelrequest</servlet-name> <servlet-path>packagename.cancelrequest</servlet-path> </servlet> <servlet-mapping> <servlet-name>cancelrequest</servlet-name> <url-pattern>/cancelrequest</url-pattern> </servlet-mapping> write javascript function as:
function cancelrequest(){ var exit = confirm('are sure want cancel request?'); if(exit == true){ document.getelementbyid('sendaddnotificationid').action = 'cancelrequest'; }else{ return; } } include id form in jsp as:
<form action="sendaddnotification" id="sendaddnotificationid" method="post"> and change anchor element as:
<a href="cancelrequest?userid=<%=idperson%>&userrnamee=<%=namee%>" onclick="cancelrequest();"> <input type="submit" value="cancel request"></input> </a>
