How do I get Selenium Button Click to work?-CodePudding

I'm a complete beginner, I have a website in which I want to click a button through python selenium, I've tried a lot of things, but I can't get it to work.

import time
from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC


chromedriver_location = executable_path=r"C:\Users\HP\Desktop\chromedriver_win32\chromedriver.exe"

driver = webdriver.Chrome(chromedriver_location)
driver.get('https://maskun.org/donate/')

donate_button = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//button[contains(@class, 'give-btn advance-btn')] and text()='Donate Now']")))
donate_button.click()

Right now, I'm getting the error:

Traceback (most recent call last):

If I inspect the button on chrome I get:

<button  tabindex="1">Donate Now<i ></i></button>

The XPath is:

//*[@id="give-form-746-1"]/div[1]/button

CodePudding user response：

you need to switch to frame first than find_elemnt

driver.get('https://maskun.org/donate/')
iframe = driver.find_element(By.XPATH, "//iframe[@name='give-embed-form']")
driver.switch_to.frame(iframe)
donate_button = driver.find_element(By.XPATH, "//button[contains(text(), 'Donate Now')]")

CodePudding user response：

You have a syntax error inside the XPath expression.
Also, you need to scroll the page down and switch to the iframe block since that button is inside an iframe.
The following code works

import time

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
options = Options()
options.add_argument("start-maximized")

webdriver_service = Service('C:\webdrivers\chromedriver.exe')
driver = webdriver.Chrome(service=webdriver_service, options=options)
url = 'https://maskun.org/donate/'
driver.get(url)
wait = WebDriverWait(driver, 20)
driver.execute_script("window.scrollBy(0, arguments[0]);", 600)
time.sleep(1)
wait.until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR, "iframe[name='give-embed-form']")))

wait.until(EC.presence_of_element_located((By.XPATH, "//button[contains(@class, 'give-btn advance-btn') and text()='Donate Now']"))).click()

Don't forget to switch from the iframe when you finished working inside it with

driver.switch_to.default_content()
