How to handle multiple jQuery popup with selenium webdriver -

i working on java selenium webdriver 2.39, have application multiple 'processing' popup display 2-5 sec , closed automatically, depend on data. now, question how handle popup, popup jquery popup. script can work further once 3 popup gets open , process data , closed automatically. however, can not use wait time script used load testing using jmeter, hence process time may take more or less 5 sec., there way can know if popup exist or not on screen? have used below given sample code returns parent window , not identify jquery popup, using below given code can if popup exist or not, if not jquery popup. can me?

public void focusonwindow() throws exception{      int i=0;      {         handles=driver.getwindowhandles();//get windows         iterator = handles.iterator();         if(iterator.hasnext()){             subwindowhandler = iterator.next();             if(subwindowhandler==null){                 i=0;             }else if(subwindowhandler!=null){                 if(subwindowhandler!=parentwindowhandler){                     popup = true;                     i=2;                 }             }         }     }while(i<2);     if(popup){         do{             handles=driver.getwindowhandles();             iterator = handles.iterator();             thread.sleep(500);             if(iterator.hasnext()){                 subwindowhandler = iterator.next();                 if(subwindowhandler!=parentwindowhandler){                     if(subwindowhandler==null){                         string source = driver.getpagesource();                         if(source==null){                             i=2;                         }                     }                 }else {                     i=0;                 }                 //system.out.println("no other popup.");             }          }while (i<2);     } } 

first of all, i'll suggest not put hard wait @ all.

if aware of of element unique , part of post processing pop screen (i.e. resulted user screen) make use of selenium waitforelement() api function intelligently wait element appear , once appeared performs further actions.

take @ this link explains advantages of using it.

and java bindings selenium in place, can use -

webdriverwait wait = new webdriverwait(driver, /*seconds=*/3); elementofpage = wait.until(presenceofelementlocated(by.id("id_of_element")));  function<webdriver, webelement> presenceofelementlocated(final locator) { return new function<webdriver, webelement>() {     public webelement apply(webdriver driver) {         return driver.findelement(locator);     } }; }
