System.setProperty(“webdriver.chrome.driver”, “C:\\softwares\\Selenium jars\\chromedriver.exe”);

// create chrome object
driver = new ChromeDriver();
driver.get(“https://www.tirerack.com/content/tirerack/desktop/en/homepage.html”);

// it will go till the end vertically
((JavascriptExecutor) driver).executeScript(“window.scrollTo(0, document.body.scrollHeight)”);

// it will come up vertically
((JavascriptExecutor) driver).executeScript(“window.scrollTo(0, -document.body.scrollHeight)”);
Thread.sleep(3000);

// it will go till the pixel specified
((JavascriptExecutor) driver).executeScript(“window.scrollBy(0,1500)”);
Thread.sleep(3000);

// it will come back till the pixel specified
((JavascriptExecutor) driver).executeScript(“window.scrollBy(0,-1500)”);

Thread.sleep(3000);

// it will go down till the object specified.
((JavascriptExecutor) driver).executeScript(“arguments[0].scrollIntoView(true);”,
driver.findElement(By.xpath(“//a[contains(text(),’Find’)]”)));
}catch(Exception e) {
System.out.println(“Exception details”+e.getMessage());
}

driver.quit();
}
}

Another method to scroll a WebDriver instance (via JavascriptExecutor):

WebDriver driver;
driver = new FirefoxDriver();
driver.get(“https://www.urlwithlongPages.xxx”);
Boolean readyStateComplete = false;
while (!readyStateComplete) {
JavascriptExecutor executor = (JavascriptExecutor) driver;
executor.executeScript(“window.scrollTo(0, document.body.offsetHeight)”);
readyStateComplete = (String) executor.executeScript(“return document.readyState”) == “complete”;
}
