On perfect HTML, WebDriver gives a NoSuchElementException on the controls - testing

Question

I was trying to automate the Reset functionality in "http://www.efrotech.com/careers" for learning purposes. When I get the control locators I see it is perfect HTML that has almost all the locators; but when I try to run the script it is not recognizing the control and throwing painful NoSuchElement exception. Can you suggest what could be going wrong in that?
package com;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.support.ui.Select;
public class ScriptChecker {
/**
* #param args
*/
public static WebDriver driver;
public static String baseUrl;
public static void main(String[] args) throws InterruptedException {
// TODO Auto-generated method stub
driver = new FirefoxDriver();
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
driver.manage().window().maximize();
baseUrl = "http://www.efrotech.com";
driver.get(baseUrl +"/careers");
new Select(driver.findElement(By.id("ddlJobs"))).selectByVisibleText("QA Engineer");
driver.findElement(By.cssSelector("input#txtName")).sendKeys("Muzaffar");
System.out.println("Done here");
}
}
I have tried every locator but unable to manipulate the control state and its values.
Stacktrace followed:
Exception in thread "main" org.openqa.selenium.NoSuchElementException: Unable to locate element: {"method":"id","selector":"ddlJobs"}
Command duration or timeout: 10.07 seconds

Answer 1

The drop down element which you are trying to use is under iFrames. Please switch to it and then proceed with your selection.
driver.switchTo().frame(driver.findElement(By.cssSelector("iframe[height='520']")));
new Select(driver.findElement(By.xpath(".//*[#id='ddlJobs']"))).selectByVisibleText("QA Engineer");
hope this solves.
