How to Identify popup window in Selenium Webdriver ?

1. First Check whether its popup window or IFrame window by using IE Developer or Find bug tools.

2. If its popup window then use following code :
driver.findElement(By.xpath("")).click();

Set s=driver.getWindowHandles();

This method will help to handle of opened windows other than parent



Iterator ite=s.iterator();

while(ite.hasNext())

{

String popupHandle=ite.next().toString();

if(!popupHandle.contains(mwh))

{

driver.switchTo().window(popupHandle);

/**/here you can perform operation in pop-up window**

//After finished your operation in pop-up just select the main window again

driver.switchTo().window(mwh);

}

}



This method will help to filter out of all opened windows



1) String parentWindowHandle = browser.getWindowHandle(); // save the current window handle.

WebDriver popup = null;

Iterator windowIterator = browser.getWindowHandles();

while(windowIterator.hasNext()) {

String windowHandle = windowIterator.next();

popup = browser.switchTo().window(windowHandle);

if (popup.getTitle().equals("Google") {

break;

}

}



2) Uncomment code for the same popup,



//action in popup "Google".

popup.findElement(By.name("q")).sendKeys("Thoughtworks");

//action in popup "Google".

popup.findElement(By.name("btnG")).submit();"



3) After the popup actions, switch the driver back to the parent window,



browser.close(); // close the popup.

browser.switchTo().window(parentWindowHandle); // Switch back to parent window.





If its IFrame then use following line.



String parentWindowHandle = driver.getWindowHandle();

driver.switchTo().Frame(driver.findelement(by.id("iframeid")));
// perform ur actions.
//revert back to parent control

driver.switchTo().window(parentWindowHandle);
