Noob here, couple of questions

[2k43l3aj5l]

Hi, I'm trying to figure this out:

1:

I'm trying to slow scroll to a specific element, and because there are multiple different elements with the same criteria and how my code works, I decided to use a for loop and do it like this:

randomhold = sb.driver.find_elements("css selector", ".randomclass")
for i in randomhold:
 differentrandomhold = i.find_element("css selector", ".differentrandomclass")
 differentrandomhold.slow_scroll_to()`

But then, I get this error:
AttributeError: 'WebElement' object has no attribute 'slow_scroll_to'

2:

If no matching element is found when using find_element, my program closes and I get this error:
selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"css selector","selector":".differentrandomclass"}
Instead of exiting the program and giving me that exception in the console, how can I handle it so that if that element is not found, it will go to else block instead?

Hello. The WebElement doesn't contain the seleniumbase methods (with a few exceptions for UC Mode).

Here's an example of slow_scroll_to():

from seleniumbase import SB

with SB() as sb:
    sb.open("https://xkcd.com/color/rgb/")
    sb.slow_scroll_to("center > table tbody tr:nth-child(36)")
    sb.sleep(1)

Use methods such as is_element_visible(selector) and is_element_present(selector) to handle flow-of-control. Eg:

if sb.is_element_visible(selector):
    # Do something here
else:
    # Do something else here

You can also use try/except blocks for error-handling. Eg:

try:
    # Do something here
except Exception:
    # Do something else here

Can I slow scroll to the xpath extracted from the found element?

 differentrandomhold = i.find_element("css selector", ".differentrandomclass")
 xpath = differentrandomhold.get_attribute("xpath")
 print(xpath)
 sb.slow_scroll_to(xpath)

If I try to do it like that, printed xpath shows "None", and then I get:

Exception: Invalid selector type: "<class 'NoneType'>"
Expecting a selector of type: "<class 'str'>" (string)!

xpath isn't an attribute of WebElement. Your call would return a None object, which you saved into your variable.

This is how hover() works:

element = driver.find_element(by=by, value=selector)
hover = ActionChains(driver).move_to_element(element)
hover.perform()

Methods such as move_to_element() are part of selenium, not seleniumbase, so I don't have the specifics memorized.

But if you're trying to avoid detection, you shouldn't be using hover() at all, as that can trigger detection. There's a uc_click() method specifically for undetected clicking. See the example: SeleniumBase/examples/raw_turnstile.py
