How to set focus to a web element in Selenium webdriver - selenium

Question

I am new to Selenium. I am learning by automating some test scenarios on MakeMyTrip website.
Scenario: Editing the user account created.
Code:(yet to be completed)
public class AccountEdit {
#Test
public void AccEdit()
{
WebDriver driver = new FirefoxDriver();
driver.get("http://www.makemytrip.com/");
driver.manage().window().maximize();
driver.findElement(By.id("ssologinlink")).click();
driver.findElement(By.id("username")).sendKeys("abcd#gmail.com");
driver.findElement(By.id("password_text")).sendKeys("*****");
driver.findElement(By.id("login_btn")).click();
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
driver.findElement(By.id("ssologinlink")).click(); **======> Here I notice the click is not happening to select the My Account or My Profile from the drop down.**
}
}
Kindly let me know how I can take the focus back to the webelement once I login.
driver.findElement(By.id("ssologinlink")).click();
works fine the first time but not post the user login.

Answer 1

Thank you for your comments. The element ID had not changed post the login. I had to wait for the user name to appear before I click on the drop down.
Below is the code which worked for me:
public class AccountEdit {
#Test
public void AccEdit()
{
WebDriver driver = new FirefoxDriver();
driver.get("http://www.makemytrip.com/");
driver.manage().window().maximize();
driver.findElement(By.id("ssologinlink")).click();
driver.findElement(By.id("username")).sendKeys(""abcd#gmail.com"");
driver.findElement(By.id("password_text")).sendKeys("*******!");
driver.findElement(By.id("login_btn")).click();
WebElement myDynamicElement = (new WebDriverWait(driver, 10)).until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//span[#id='ssologinlink']/strong[contains(text(),'user')]")));
myDynamicElement.click();
}
}

Answer 2

Try waiting for the element to be clickable with Expected Conditions of Explicit waits. See the doc here
public class AccountEdit {
#Test
public void AccEdit()
{
WebDriver driver = new FirefoxDriver();
driver.get("http://www.makemytrip.com/");
driver.manage().window().maximize();
driver.findElement(By.id("ssologinlink")).click();
driver.findElement(By.id("username")).sendKeys("abcd#gmail.com");
driver.findElement(By.id("password_text")).sendKeys("*****");
driver.findElement(By.id("login_btn")).click();
//Waiting for the element to be clickable with Explicit wait
WebElement myDynamicElement = (new WebDriverWait(driver, 10))
.until(ExpectedConditions.elementToBeClickable(By.id("ssologinlink")));
myDynamicElement.click();
}
}

Some time element ID gets changed post login(something like dynamic ID).. pls. check the element ID again and update..
