[java] How to handle Pop-up in Selenium WebDriver using Java

I want to handle sign-in part in rediff.com, but the below code doesn't work for that:

driver.get("http://www.rediff.com/");
WebElement sign = driver.findElement(By.xpath("//html/body/div[3]/div[3]/span[4]/span/a"));
sign.click();
String myWindowHandle = driver.getWindowHandle();
driver.switchTo().window(myWindowHandle);
WebElement email_id= driver.findElement(By.xpath("//*[@id='signin_info']/a[1]"));
email_id.sendKeys("hi");

If myWindowHandle is not the correct string, then let me know how to get the pop-up Window name, because I can't find the name of the pop-up window.

       //get the main handle and remove it
       //whatever remains is the child pop up window handle

       String mainHandle = driver.getWindowHandle();
       Set<String> allHandles = driver.getWindowHandles();
       Iterator<String> iter = allHandles.iterator();
       allHandles.remove(mainHandle);
       String childHandle=iter.next();

When the toastr message poped up on the screen of firefox. the below tag was displayed in fire bug.

<div class="toast-message">Invalid Credentials, Please check Password</div>.

I took the screenshot at that time. And did the below changes in selenium java code.

String alertText = "";
WebDriverWait wait = new WebDriverWait(driver, 5);
wait.until(ExpectedConditions.visibilityOfElementLocated(By.className("toast-message")));
WebElement toast1 = driver.findElement(By.className("toast-message"));  
alertText = toast1.getText();
System.out.println( alertText);

And my issue of toastr popup got resolved.

String parentWindowHandler = driver.getWindowHandle(); // Store your parent window
String subWindowHandler = null;

Set<String> handles = driver.getWindowHandles(); // get all window handles
Iterator<String> iterator = handles.iterator();

subWindowHandler = iterator.next();

driver.switchTo().window(subWindowHandler); // switch to popup window

// Now you are in the popup window, perform necessary actions here

driver.switchTo().window(parentWindowHandler);  // switch back to parent window

You can handle popup window or alert box:

Alert alert = driver.switchTo().alert();
alert.accept();

You can also decline the alert box:

Alert alert = driver.switchTo().alert();
alert().dismiss();

You can use the below code inside your code when you get any web browser pop-up alert message box.

// Accepts (Click on OK) Chrome Alert Browser for RESET button.

Alert alertOK = driver.switchTo().alert();
alertOK.accept();



//Rejects (Click on Cancel) Chrome Browser Alert for RESET button.

Alert alertCancel = driver.switchTo().alert();
alertCancel.dismiss();

I found the solution for the above program, which had the goal of signing in to http://rediff.com

public class Handle_popupNAlert
{
    public static void main(String[] args ) throws InterruptedException
    {
        WebDriver driver= new FirefoxDriver(); 
        driver.get("http://www.rediff.com/");
        WebElement sign = driver.findElement(By.xpath("//html/body/div[3]/div[3]/span[4]/span/a"));
        sign.click();

        Set<String> windowId = driver.getWindowHandles();    // get  window id of current window
        Iterator<String> itererator = windowId.iterator();   

        String mainWinID = itererator.next();
        String  newAdwinID = itererator.next();

        driver.switchTo().window(newAdwinID);
        System.out.println(driver.getTitle());
        Thread.sleep(3000);
        driver.close();

        driver.switchTo().window(mainWinID);
        System.out.println(driver.getTitle());
        Thread.sleep(2000);

        WebElement email_id= driver.findElement(By.xpath("//*[@id='c_uname']"));
        email_id.sendKeys("hi");
        Thread.sleep(5000);

        driver.close();
        driver.quit();
    }  
}

Do not make the situation complex. Use ID if they are available.

driver.get("http://www.rediff.com");
WebElement sign = driver.findElement(By.linkText("Sign in"));
sign.click();
WebElement email_id= driver.findElement(By.id("c_uname"));
email_id.sendKeys("hi");

public void Test(){

     WebElement sign = fc.findElement(By.xpath(".//*[@id='login-scroll']/a"));
        sign.click();
        WebElement LoginAsGuest=fc.findElement(By.xpath(".//*[@id='guest-login-option']"));
        LoginAsGuest.click();
        WebElement email_id= fc.findElement(By.xpath(".//*[@id='guestemail']"));
        email_id.sendKeys("[email protected]");
        WebElement ContinueButton=fc.findElement(By.xpath(".//*[@id='contibutton']"));
        ContinueButton.click();

}
