Page scroll up or down in Selenium WebDriver (Selenium 2) using java

Asked 6/9, 2012 at 4:51 Answered 14/7, 2021 at 5:10

Solved java selenium selenium-webdriver scroll selenium-rc

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)?

Scenario/Test steps:

Open a browser and navigate to TestURL
Scroll down some pixel and scroll up

For Scroll down:

WebDriver driver = new FirefoxDriver();
JavascriptExecutor jse = (JavascriptExecutor)driver;
jse.executeScript("window.scrollBy(0,250)");

OR, you can do as follows:

jse.executeScript("scroll(0, 250);");

For Scroll up:

jse.executeScript("window.scrollBy(0,-250)");
OR,
jse.executeScript("scroll(0, -250);");

Scroll to the bottom of the page:

Scenario/Test steps:

Open a browser and navigate to TestURL
Scroll to the bottom of the page

Way 1: By using JavaScriptExecutor

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

Way 2: By pressing ctrl+end

driver.findElement(By.cssSelector("body")).sendKeys(Keys.CONTROL, Keys.END);

Way 3: By using Java Robot class

Robot robot = new Robot();
robot.keyPress(KeyEvent.VK_CONTROL);
robot.keyPress(KeyEvent.VK_END);
robot.keyRelease(KeyEvent.VK_END);
robot.keyRelease(KeyEvent.VK_CONTROL);

The above code is for scroll down. For scroll up: jse.executeScript("scroll(250, 0)"); Only the value would be reverse – Fumigator 18/1, 2013 at 6:30

No - that will scroll to the right. Scroll up will be scroll(0,-250) – Sera 4/4, 2014 at 3:15

Thanks Stephen. Both scroll(250,0) and scroll(0,-250) should work for scroll up. – Fumigator 4/4, 2014 at 6:0

For scroll up (0, -250) is logical. I do agree with Stephen. – Fumigator 10/7, 2015 at 4:6

jse.executeScript("window.scrollBy(0,250)", ""); it works fine. I want to use variable as int y = 250; jse.executeScript("window.scrollBy(0,y)", ""); An error shows in this case as "y is not defined". How to use variable in this case? – Fumigator 26/2, 2016 at 12:29

@RiponAlWasim Did you ever find a solution for that issue? – Draco 8/10, 2016 at 1:56

@RiponAlWasim you would just concatenate the variable into your string in whatever way you like, e.g. jse.executeScript("window.scrollBy(0," + y + ")", "") – Delude 4/1, 2017 at 10:27

Scrolling to the bottom of a page:

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

Desdamonna answered 20/6, 2015 at 17:33 Comment(3)

just to mention, it is for scroll down – Demesne 5/9, 2016 at 12:5

it is not working in my salesforce application, where as window.scrollBy(0,250) works. But it does not scroll to the end of the page. – Epizootic 30/7, 2019 at 8:32

@AshokkumarGanesan did you try window.scrollBy(0,document.body.scrollHeight)? – Aggarwal 18/11, 2023 at 19:48

There are many ways to scroll up and down in Selenium Webdriver I always use Java Script to do the same.

Below is the code which always works for me if I want to scroll up or down

 // This  will scroll page 400 pixel vertical
  ((JavascriptExecutor)driver).executeScript("scroll(0,400)");

You can get full code from here Scroll Page in Selenium

If you want to scroll for a element then below piece of code will work for you.

je.executeScript("arguments[0].scrollIntoView(true);",element);

You will get the full doc here Scroll for specific Element

This worked if I have to scroll down. How can I scroll up the page? – Fertility 27/12, 2017 at 21:14

The first snippet of code only scrolls the page, not the element itself, how can I do that? – Harmful 5/1, 2018 at 22:46

This may not be an exact answer to your question (in terms of WebDriver), but I've found that the java.awt library is more stable than selenium.Keys. So, a page down action using the former will be:

Robot robot = new Robot();
robot.keyPress(KeyEvent.VK_PAGE_DOWN);
robot.keyRelease(KeyEvent.VK_PAGE_DOWN);

Morley answered 4/6, 2015 at 17:26 Comment(0)

JavascriptExecutor js = ((JavascriptExecutor) driver);

Scroll down:

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

Scroll up:

js.executeScript("window.scrollTo(0, -document.body.scrollHeight);");

Try this:

Actions dragger = new Actions(driver);
WebElement draggablePartOfScrollbar = driver.findElement(By.xpath("//*[@id='jobreslist_outercontainer']/div/div[2]/div"));

// drag downwards
int numberOfPixelsToDragTheScrollbarDown = 50;
for (int i = 10; i < 500; i += numberOfPixelsToDragTheScrollbarDown) {
    try {
        // this causes a gradual drag of the scroll bar, 10 units at a time
        dragger.moveToElement(draggablePartOfScrollbar).clickAndHold().moveByOffset(0, numberOfPixelsToDragTheScrollbarDown).release().perform();
        Thread.sleep(1000L);
    } catch(Exception e1) {}
}

// now drag opposite way (downwards)
numberOfPixelsToDragTheScrollbarDown = -50;
for (int i = 500; i > 10; i += numberOfPixelsToDragTheScrollbarDown) {
    // this causes a gradual drag of the scroll bar, -10 units at a time
    dragger.moveToElement(draggablePartOfScrollbar).clickAndHold().moveByOffset(0, numberOfPixelsToDragTheScrollbarDown).release().perform();
    Thread.sleep(1000L);
}

I actually like this since it scrolls how a user would – Buddle 19/1, 2017 at 18:15

Javascript

We can scroll to a specific element:

const element = await driver.findElement(...)
await driver.executeScript("arguments[0].scrollIntoView(true);", element)
await driver.sleep(500);

Deitz answered 14/7, 2021 at 5:10 Comment(0)

You should add a scroll to the page to select all elements using:

Selenium.executeScript("window.scrollBy(0,450)", "");

If you have a large list, add the scroll several times through the execution. Note the scroll only go to a certain point in the page for example (0, 450).

Roadability answered 24/8, 2016 at 16:39 Comment(0)

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.

@raffamaiden put heads on your browser lol... I'm not sure why anyone would want to test against a browser that their users aren't actually going to use anyways – Buddle 11/7, 2017 at 17:8

You are right. But the OP did not specify it was testing an app. You can use Selenium also for other purposes (e.g. webscraping). – Jesus 12/7, 2017 at 11:6

1.To scroll page to the bottom use window.scrollTo(0,document.body.scrollHeight) as parameter

//Code to navigate to bottom

WebDriver driver = new ChromeDriver();
JavascriptExecutor jsExecuter = (JavascriptExecutor)driver;
jsExecuter.executeScript(window.scrollTo(0,document.body.scrollHeight));

2.To scroll page to the top use window.scrollTo(0,document.body.scrollTop) as parameter

//Code to navigate to top

WebDriver driver = new ChromeDriver();
JavascriptExecutor jsExecuter = (JavascriptExecutor)driver;
jsExecuter.executeScript(window.scrollTo(0,document.body.scrollTop));

3.To scroll page to the Left use window.scrollTo(0,document.body.scrollLeft) as parameter

//Code to navigate to left

WebDriver driver = new ChromeDriver();
JavascriptExecutor jsExecuter = (JavascriptExecutor)driver;
jsExecuter.executeScript(window.scrollTo(0,document.body.scrollLeft));

4.To scroll to certain point window.scrollTo(0,500) as parameter

//Code to navigate to certain point e.g. 500 is passed as value here

WebDriver driver = new ChromeDriver();
JavascriptExecutor jsExecuter = (JavascriptExecutor)driver;
jsExecuter.executeScript(window.scrollTo(0,500));

To check the navigation directly in browser , open developers tool in browser and navigate to console. Execute the command on console window.scrollTo(0,400)

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.

Dikmen answered 3/11, 2016 at 9:11 Comment(0)

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.

Podium answered 10/11, 2016 at 12:29 Comment(0)

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

JavascriptExecutor is best to scroll down a web page window.scrollTo Function in JavascriptExecutor can do this

JavascriptExecutor js = ((JavascriptExecutor) driver);
js.executeScript("window.scrollTo(0,100");

Above code will scroll down by 100 y coordinates

JavascriptExecutor jse = (JavascriptExecutor)driver;
jse.executeScript("window.scrollBy(0,250)");

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)”);

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