How to switch control to pop-up window ?

If you want to do any operations in pop-up window you need to switch the control to pop-up window then do all your operations in that and finally close the pop-up window and again select the default (main ) window.


here is WebDriver logic to select Pop-up window


1 . Pop-up window has name/id

     driver.switchTo().window("<window name>");

2. Pop-up window doesn't have name / you don't want to hard code the window name then go for below logic.

Method-1

• before opening pop-up get the main window handle.

             String mainWindowHandle=driver.getWindowHandle();

• open the pop-up (click on element which causes open a new window)

             webElement.click();

• try to get all available open window handles with below command. (the below command returns all window handles as Set)

            Set s = driver.getWindowHandles();

• from that above set try get newly opened window and switch the control to that (pop-up window handle), as we already know the mainWindowHandle.

          Set s = driver.getWindowHandles();

Iterator ite = s.iterator();

while(ite.hasNext())

            {

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

if(!popupHandle.contains(mainWindowHandle))

{

driver.switchTo().window(popupHandle);

}

}

• Now control is in pop-up window, do all your operations in pop-up and close the pop-up window.
• Select the default window again.

                 driver.switchTo().window( mainWindowHandle );

Method-2

// get all the window handles before the popup window appears
 Set beforePopup = driver.getWindowHandles();
     
// click the link which creates the popup window
driver.findElement(by).click();
  
// get all the window handles after the popup window appears
Set afterPopup = driver.getWindowHandles();
     
// remove all the handles from before the popup window appears
afterPopup.removeAll(beforePopup);

// there should be only one window handle left
if(afterPopup.size() == 1) {
          driver.switchTo().window((String)afterPopup.toArray()[0]);
 }
