How to implement scroll on WebElement on Selenium in Java?

Question

I have a scroll that is responsible to scroll a table on the page, not the whole page, so I cant use window.scrollBy

I've tried to find the scroll's container (I don't see a scroll specific object in the DOM) and use the following code:

JavascriptExecutor jse =  (JavascriptExecutor)driver;

jse.executeScript("arguments[0].scrollBy(0,200);",scrollContainer);

(ScrollContainer is WebElement)

I'm getting the exception:

org.openqa.selenium.WebDriverException: unknown error: arguments[0].scrollBy is not a function

What am I doing wrong?

Thanks

The method HTMLElement.scrollBy is not supported by all the browsers. Use scrollLeft or scrollTop instead:

JavascriptExecutor jse =  (JavascriptExecutor)driver;
jse.executeScript("arguments[0].scrollTop += 200;", scrollContainer);
