How to Scroll Pages in Selenium 2 with WebDriver (Java)?

Page Scrolling in Selenium 2 with WebDriver (Java)

In Selenium 1, page scrolling was achieved using the selenium.getEval("scrollBy(0, 250)") method. In Selenium 2, the equivalent code is as follows:

Scrolling Down or Up

WebDriver driver = new FirefoxDriver();
JavascriptExecutor jse = (JavascriptExecutor)driver;

// Scroll down
jse.executeScript("window.scrollBy(0,250)");
// OR
jse.executeScript("scroll(0, 250);");

// Scroll up
jse.executeScript("window.scrollBy(0,-250)");
// OR
jse.executeScript("scroll(0, -250);");

Scrolling to the Bottom of the Page

Using JavaScriptExecutor:

jse.executeScript("window.scrollTo(0, document.body.scrollHeight)");

Using Keys.CONTROL Keys.END:

driver.findElement(By.cssSelector("body")).sendKeys(Keys.CONTROL, Keys.END);

Using the Java Robot Class:

Robot robot = new Robot();
robot.keyPress(KeyEvent.VK_CONTROL);
robot.keyPress(KeyEvent.VK_END);
robot.keyRelease(KeyEvent.VK_END);
robot.keyRelease(KeyEvent.VK_CONTROL);
