Selenium_Part 18: How to automate Scroll bar in Selenium? Use of JavascriptExecutor class?
#selenium #webDriver #scrollBar # JavascriptExecutor
JavascriptExecutor is a class and we have to cast out driver into JavascriptExecutor. Once it's done. We can use reference variable to use executeScript () method. And this method is used to execute Javascript code. Since Scroll bar is a Javascript function, so JavascriptExecutor class is the best option to automate in Selenium.
Example:
// Scroll down of a page :
JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("scroll(0, 500);");
// Scroll up of a page :
JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("scroll(0, -500);");
// Scroll page all the way down:
JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("scrollTo(0,document.body.scrollHeight )");
