Question

Can anybody please help me out to automate scroll down functionality with WebDriver using Java?

In my case, For yahoo mail "Sign In" is getting displayed (visible) once I scroll down the mouse vertically.

Answer 1

You can scroll down vertically by using the following code:

((JavascriptExecutor) driver).executeScript("scroll(0,250);");

Similarly, it is also possible to scroll up by changing y coordinate as negative:

((JavascriptExecutor) driver).executeScript("scroll(0, -250);");

You can also use the following code:
For scroll down:

((JavascriptExecutor) driver).executeScript("window.scrollBy(0,250)", "");

For scroll up:

((JavascriptExecutor) driver).executeScript("window.scrollBy(0, -250)", "");
