How to check if a popup window is open or not using Selenium WebDriver in Java

Question

I'm trying to check whether the popup window I want to open is opened or not.

I have checked some question answers like

How would you check if a popup window exists using selenium webdriver?

But, nothings helped to solve the problem.

Here, first I open the login window by clicking the login button.

driver.findElement(By.xpath("//a[@id='login_btn']")).click(); // Click Login Button

I even tried getPageSource() but, it seems not working.

Any kind of help would be appreciated.

Thanks in advance. :)

Answer 1

String mwh=driver.getWindowHandle();

Now try to open the popup window by performing some action:

driver.findElement(By.xpath("")).click();

Set s=driver.getWindowHandles(); //this method will gives you the handles of all opened windows

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);
    }
}
