Answers for "javascript code for scroll down up to end of in web page"

scrolling in selenium

Selenium does not have a method for scrolling
 but there are some ways to scroll:
 
   #1 ->=moveToElement= coming from Actions class
   will scroll down and up to given web element
   #2 Using JSExecutor: We can inject JavaScript
   code in our Java+Selenium code using JSExecutor
   which helps us scroll up, down, left, right.
   We need to create instance of JS executor,
   then cast our driver type of it.
==================================================   
   
  syntax is =   
   JavaScriptExecutor js = (JavaScriptExecutor) Driver.getDriver();
   js.executeScript("in here we need to pass js code that scrolls");
    
  
     js.executeScript("window.scrollBy(0,250)");
     js.executeScript("arguments[0].scrollIntoView(true);", WebElement);
