Unable to press "TAB" in cdp mode

[parvinders347]

Hey,

Im trying to click on buster extension button but im unable to click on it because its in #shadow-root(closed) so i wanted to use tab + tab + enter but still its not clicking on recaptcha windows buttons but in whole browser

i tried in puppeteer its working great in puppeteer tab + tab + enter but im trying to do same in seleniumbase is it possible?

my code:

from seleniumbase import SB
import os
import time

def main():
    # Path to your unpacked Buster extension directory
    extension_dir = r"E:\Recaptcha\buster"
    
    # Verify the extension directory exists
    if not os.path.isdir(extension_dir):
        raise FileNotFoundError(f"Extension directory not found: {extension_dir}")
    
    with SB(uc=True, extension_dir=extension_dir) as sb:
        # Navigate to the reCAPTCHA demo page and activate CDP mode
        url = "https://www.google.com/recaptcha/api2/demo"
        sb.activate_cdp_mode(url)
        print("Browser title:", sb.cdp.get_title())
        
        # Variables to control retry logic
        max_detection_retries = 5
        detection_delay_between_retries = 2  # seconds
        max_solving_retries = 60
        solving_delay_between_retries = 2  # seconds
        captcha_token = None
        captcha_detected = False
        
        # Try to detect the reCAPTCHA element
        for attempt in range(max_detection_retries):
            captcha_exists = sb.execute_script("return document.getElementById('g-recaptcha-response') !== null;")
            if captcha_exists:
                print("CAPTCHA element detected")
                captcha_detected = True
                break
            time.sleep(detection_delay_between_retries)
            print(f"Waiting for CAPTCHA to appear... Attempt {attempt + 1}/{max_detection_retries}")
        
        if not captcha_detected:
            print("CAPTCHA element did not appear within the allotted time for detection")
            return
        
        # Click the reCAPTCHA checkbox using nested click
        try:
            sb.cdp.nested_click("iframe[title='reCAPTCHA']", ".recaptcha-checkbox-border")
        except Exception as e:
            print(f"Failed to click checkbox: {e}")
        
        # Wait a moment for the challenge iframe to appear
        time.sleep(2)
        
        # Use uc_gui methods to handle keyboard navigation through shadow DOM
        time.sleep(2)  # Wait for a moment after clicking checkbox
        sb.uc_gui_press_keys(["\t", "\t"])  # Press Tab twice to focus on Buster button
        time.sleep(1)
        sb.uc_gui_press_keys(["ENTER"])  # Activate Buster
        time.sleep(5)  # Wait for Buster to work
        
        # Try to get the CAPTCHA token
        for attempt in range(max_solving_retries):
            captcha_token = sb.execute_script("""
                (() => {
                    const responseField = document.getElementById('g-recaptcha-response');
                    if (responseField) {
                        return responseField.value;
                    }
                    return null;
                })();
            """)
            
            if captcha_token:
                print(f"CAPTCHA Token Found: {captcha_token[:30]}...") # Show first 30 chars for security
                break
                
            time.sleep(solving_delay_between_retries)
            print(f"Waiting for CAPTCHA to be solved... Attempt {attempt + 1}/{max_solving_retries}")

uc_gui_press_keys

I noticed you confused CDP and WebDriver, as they share similar methods.

use sb.cdp.gui_press_keys(["\t", "\t"]) instead sb.uc_gui_press_keys(["\t", "\t"])

use sb.cdp.evaluate(expression) instead sb.execute_script(expression)

@mdmintz can you check this please, thanks

Use PyAutoGUI to interact with Closed Shadow Root. There's not much else that can be done with that.
