08. Page Scroll different ways using Selenium WebDriver

Using JavaScript


Scroll Down:

import org.openqa.selenium.JavascriptExecutor;

WebDriver driver = new FirefoxDriver();
JavascriptExecutor jse = (JavascriptExecutor)driver;
jse.executeScript("scroll(0, 250)"); //y value '250' can be altered

Scroll up:

JavascriptExecutor jse = (JavascriptExecutor)driver;
jse.executeScript("scroll(250, 0)"); //x value '250' can be altered

Scroll bottom of the Page:

JavascriptExecutor jse = (JavascriptExecutor)driver;
jse.executeScript("window.scrollTo(0,Math.max(document.documentElement.scrollHeight,document.body.scrollHeight,document.documentElement.clientHeight));");

                                                                      (or)

Actions actions = new Actions(driver);
actions.keyDown(Keys.CONTROL).sendKeys(Keys.END).perform();

Full scroll to bottom in slow motion:

for (int second = 0;; second++) {
        if(second >=60){
            break;
        }
            ((JavascriptExecutor) driver).executeScript("window.scrollBy(0,400)", ""); //y value '400' can be altered
            Thread.sleep(3000);
}

                                                                          (or)

JavascriptExecutor jse = (JavascriptExecutor)driver;
for (int second = 0;; second++) {
        if(second >=60){
            break;
        }
            jse.executeScript("window.scrollBy(0,800)", ""); //y value '800' can be altered
            Thread.sleep(3000);
}

Scroll automatically to your WebElement:

Point hoverItem =driver.findElement(By.xpath("Value")).getLocation();
((JavascriptExecutor)driver).executeScript("return window.title;");  
Thread.sleep(6000);
((JavascriptExecutor)driver).executeScript("window.scrollBy(0,"+(hoverItem.getY())+");");
// Adjust your page view by making changes right over here (hoverItem.getY()-400)

                                                                      (or)

((JavascriptExecutor)driver).executeScript("arguments[0].scrollIntoView();", driver.findElement(By.xpath("Value')]")));

Using KeyBoard

We have two options for scrolling in web page. 

Using Actions Class

package name  : org.openqa.selenium.interactions.Actions 

java code :

                      Ctrl+End | Scroll to Bottom of the page

                     Actions actions = new Actions(driver);
                     actions.keyDown(Keys.CONTROL).sendKeys(Keys.END).perform();

Without Using Actions Class 

java code :

                     for(int i=0;i<10;i++)

                    {

                             driver.findElement(By.tagName("body")).sendKeys(Keys.DOWN);

                    }
