Page scroll up or down in Selenium WebDriver (Sele

Question

I have written the following code in Selenium 1 (a.k.a Selenium RC) for page scrolling using java:

selenium.getEval("scrollBy(0, 250)");

What is the equivalent code in Selenium 2 (WebDriver)?

Answer 1

Scrolling to Bottom of a page:

JavascriptExecutor js = ((JavascriptExecutor) driver);
js.executeScript("window.scrollTo(0, document.body.scrollHeight)");

Answer 2

JavascriptExecutor jse = ((JavascriptExecutor) driver);
jse.executeScript("window.scrollTo(0, document.body.scrollHeight)");

This code works for me. As the page which I'm testing, loads as we scroll down.

Answer 3

I did not want to use JavaScript, or any external libraries, so this was my solution (C#):

IWebElement body = Driver.FindElement(By.TagName("body"));

IAction scrollDown = new Actions(Driver)
    .MoveToElement(body, body.Size.Width - 10, 15) // position mouse over scrollbar
    .ClickAndHold()
    .MoveByOffset(0, 50) // scroll down
    .Release()
    .Build();

scrollDown.Perform();

You can also easily make this an extension method for scrolling up or down on any element.

Thanks for Ripon Al Wasim's answer. I did some improvement. because of network problems, I retry three times until break loop.

driver.get(url)
# Get scroll height
last_height = driver.execute_script("return document.body.scrollHeight")
try_times = 0
while True:
    # Scroll down to bottom
    driver.execute_script("window.scrollBy(0,2000)")

    # Wait to load page
    time.sleep(scroll_delay)
    # Calculate new scroll height and compare with last scroll height
    new_height = driver.execute_script("return document.body.scrollHeight")

    if last_height == new_height:
        try_times += 1

    if try_times > 3:
        try_times = 0
        break
    last_height = new_height

Answer 5

Javascript executor always does the job perfectly:

((JavascriptExecutor) driver).executeScript("scroll(0,300)");

where (0,300) are the horizontal and vertical distances respectively. Put your distances as per your requirements.

If you a perfectionist and like to get the exact distance you like to scroll up to on the first attempt, use this tool, MeasureIt. It's a brilliant firefox add-on.

1. If you want to scroll the page vertically to perform some action, you can do it using the following JavaScript. ((JavascriptExecutor)driver).executeScript(“window.scrollTo(0, document.body.scrollHeight)”);

       Where ‘JavascriptExecutor’ is an interface, which helps executing JavaScript through Selenium WebDriver. You can use the following code to import.
   

import org.openqa.selenium.JavascriptExecutor;

2.If you want to scroll at a particular element, you need to use the following JavaScript.

WebElement element = driver.findElement(By.xpath(“//input [@id=’email’]”));((JavascriptExecutor) driver).executeScript(“arguments[0].scrollIntoView();”, element);

Where ‘element’ is the locator where you want to scroll.

3.If you want to scroll at a particular coordinate, use the following JavaScript.
((JavascriptExecutor)driver).executeScript(“window.scrollBy(200,300)”); Where ‘200,300’ are the coordinates.

4.If you want to scroll up in a vertical direction, you can use the following JavaScript. ((JavascriptExecutor) driver).executeScript(“window.scrollTo(document.body.scrollHeight,0)”);

5. If you want to scroll horizontally in the right direction, use the following JavaScript. ((JavascriptExecutor)driver).executeScript(“window.scrollBy(2000,0)”);

6. If you want to scroll horizontally in the left direction, use the following JavaScript. ((JavascriptExecutor)driver).executeScript(“window.scrollBy(-2000,0)”);
