Using the Selenium webdriver to reach the bottom of the page by scrolling vertically

Question

Using the Selenium webdriver to reach the bottom of the page by scrolling vertically

Is there a way to determine if I have scrolled to the bottom of the page vertically?

I have been using Webdriver and pressing the page down key repeatedly within a for loop, like so:

for(int di=0; di<40; di++) { 
   driver.findElement(By.tagName("body")).sendKeys(Keys.PAGE_DOWN);
   Thread.sleep(1500);
}

However, my for loop always runs 40 times regardless of the actual size of the page. I am looking for a solution to accurately detect when I have reached the end of the page so that I can break out of the loop at that point.

To start, you should select an element located at the bottom of the webpage. Let's assume there is a footer tag with the unique identifier company-email.

boolean flag = true;
while(flag){
if(driver.findElements(By.id("company-email")).size()>0){

    flag = false;
}
else{

   driver.findElement(By.tagName("body")).sendKeys(Keys.PAGE_DOWN);
   Thread.sleep(1500);
   }
}

If you need to scroll to the end of a page, you can use the following method:

public static void scrollToEndOfPage(WebDriver driver) {
        ((JavascriptExecutor) driver).executeScript("window.scrollTo(0, document.body.scrollHeight)");
    }

Once this code has been executed, you can continue with other operations.

To scroll to a specific WebElement on the page, you can use the following method:

 public static void scrollToElement(WebDriver driver, WebElement element) {
            ((JavascriptExecutor)driver).executeScript("arguments[0].scrollIntoView();", element);
        }

I hope this information is helpful to you.

Thank you for the encouragement! I finally came up with an idea and successfully implemented it to meet my expectations.

The first step is to calculate the scroll height.

 JavascriptExecutor executor = (JavascriptExecutor) driver;
            long value = (Long) executor.executeScript("return document.body.scrollHeight");

Next, create a loop to scroll through the page.

for (int f = 500; f <= value; f += 500) {
            JavascriptExecutor jsc = (JavascriptExecutor) driver;
            jsc.executeScript("window.scrollTo(0," + f + ")");
            Thread.sleep(1500);
        }
