scroll up the page to the top in selenium

Question

How to scroll the webpage to the top of the page.

I know scrolling the page to the bottom is:

window.scrollTo(0,document.body.scrollHeight)
<         


        

Answer 1

To scroll to the top of the page, just scroll to the 0, 0:

window.scrollTo(0, 0);

Or, as an alternative option, you can scroll into view of the header element (or some other element on top):

WebElement element = driver.findElement(By.tagName("header"));

JavascriptExecutor js = (JavascriptExecutor)driver;
js.executeScript("arguments[0].scrollIntoView();", element);
