Scrolling with JavaScript

Common Scroll Scripts

js.executeScript("window.scrollBy(0, 600);");                          // down 600 px
js.executeScript("window.scrollTo(0, document.body.scrollHeight);");   // to the bottom
js.executeScript("arguments[0].scrollIntoView({block: 'center'});", driver.findElement(By.id("reviews")));
Long y = (Long) js.executeScript("return Math.round(window.scrollY);");
System.out.println("Scrolled to y=" + y);

Example

Output:

Run JsScrollTest.main()

Example output

Scrolled to y=2140

Why block center

scrollIntoView() with the default puts the element at the very top, where ShopEase's sticky header covers it, and the next click fails with ElementClickInterceptedException. {block: 'center'} keeps it in the middle of the screen.
