[python] Scrolling to element using webdriver?

I am still learning and in response to one of my questions: here, I was told to that it might be due because the element in question is not in view.

I looked through the documentation and SO, here was the most relevant answer: here

You can use the "org.openqa.selenium.interactions.Actions" class to move to an element:

WebElement element = driver.findElement(By.id("my-id"));
Actions actions = new Actions(driver);
actions.moveToElement(element);
## actions.click();
actions.perform();

When I try to use the above to scroll to the element: It says WebElement not defined.

I think this is because I have not imported the relevant module. Can someone point out what I am supposed to import?

Edit: As pointed out by alecxe, this was java code.

But in the meantime right after trying to figure it out for some time. I have found out the import method for WebElement:

from selenium.webdriver.remote.webelement import WebElement

Might help someone like me.

The how of it is also a good lesson, IMO:

Went to: Documentation The

class selenium.webdriver.remote.webelement.WebElement(parent, id_, w3c=False)

Need to be separated into the command form mentioned above.

It's not a direct answer on question (its not about Actions), but it also allow you to scroll easily to required element:

element = driver.find_element_by_id('some_id')
element.location_once_scrolled_into_view

This actually intend to return you coordinates (x, y) of element on page, but also scroll down right to target element

There is another option to scroll page to required element if element has "id" attribute

If you want to navigate to page and scroll down to element with @id, it can be done automatically by adding #element_id to URL...

Example

Let's say we need to navigate to Selenium Waits documentation and scroll page down to "Implicit Wait" section. We can do

driver.get('https://selenium-python.readthedocs.io/waits.html')

and add code for scrolling...OR use

driver.get('https://selenium-python.readthedocs.io/waits.html#implicit-waits')

to navigate to page AND scroll page automatically to element with id="implicit-waits" (<div class="section" id="implicit-waits">...</div>)

Example:

driver.execute_script("arguments[0].scrollIntoView();", driver.find_element_by_css_selector(.your_css_selector))

This one always works for me for any type of selectors. There is also the Actions class, but for this case, it is not so reliable.

You can scroll to the element by using javascript through the execute_javascript method. For example here is how I do it using SeleniumLibrary on Robot Framework:

web_element = self.selib.find_element(locator)
self.selib.execute_javascript(
    "ARGUMENTS",
    web_element,
    "JAVASCRIPT",
    'arguments[0].scrollIntoView({behavior: "instant", block: "start", inline: "start"});'
)

In addition to move_to_element() and scrollIntoView() I wanted to pose the following code which attempts to center the element in the view:

desired_y = (element.size['height'] / 2) + element.location['y']
window_h = driver.execute_script('return window.innerHeight')
window_y = driver.execute_script('return window.pageYOffset')
current_y = (window_h / 2) + window_y
scroll_y_by = desired_y - current_y

driver.execute_script("window.scrollBy(0, arguments[0]);", scroll_y_by)

This can be done using driver.execute_script():-

driver.execute_script("document.getElementById('myelementid').scrollIntoView();")
