Scroll Web Page in Selenium

WebDriver driver = new ChromeDriver();

1. Scroll to specific location

- Convert driver object to Javascript executor. This is called type casting.

JavascriptExecutor JS = (JavascriptExecutor)driver;
JS.executeScript("window.scrollTo(0,2000)");

2. Scroll to specific element
- Convert driver object to Javascript executor. This is called type casting.

JavascriptExecutor JS = (JavascriptExecutor)driver;

WebElement name = driver.findElement(By.id("name")); //Store element in object of WebElement
JS.executeScript("arguments[0].scrollIntoView(true)",name); //arguments[0] means first index of page starting at 0. Pass name object so it can scroll till that element.

3. Scroll to bottom of the page
- Convert driver object to Javascript executor. This is called type casting.

JavascriptExecutor JS = (JavascriptExecutor)driver;
JS.executeScript("window.scrollTo(0,document.body.scrollHeight");

4. Scroll Horizontally
- Convert driver object to Javascript executor. This is called type casting.

JavascriptExecutor JS = (JavascriptExecutor)driver;
JS.executeScript("window.scrollTo(2000,0)");

You can use "Option 2. Scroll to Specific element" if you are aware of element.

5. Slide Bar

WebElement slideBar = driver.findElement(By.xpath("//input[@name='slidebar'"));
slideBar.sendKeys(Keys.END);


6. Scroll dynamically loading pages
- Convert driver object to Javascript executor. This is called type casting.

JavascriptExecutor JS = (JavascriptExecutor)driver;

long previousHeight = (long)(JS.executeScript("return document.body.scrollHeight"));
While(true){
    JS.executeScript("window.scrollTo(0,document.body.scrollHeight)");
    Thread.sleep(2000);
    long currentHeight = (long)(JS.executeScript("return document.body.scrollHeight"));
    if(previousHeight == currentHeight)
        break;
   
    previousHeight = currentHeight;
}
