How to know if the javascript code has been executed in Selenium Java?

Question

I have this part of the code in my Selenium Webdriver test in java . I use this javascript code to scroll to a particular value i in the page.

((JavascriptExecutor) driver).executeScript("scroll(0,"+i+");");

scroll(0,y) doesn't return a value. Is there any way to know if this script has been executed ?

Answer 1

Did you try getting a return value from the script which then you can handle from Selenium itself? Try using:

if(window.pageYOffset!= undefined){
  return [pageXOffset, pageYOffset];
}

This will return the offsets for you after the scroll. You can then assert if this scroll position is the one you want or not.
