您能帮我使用Selenium单击“添加到购物车”按钮吗？

Question

我正在尝试做一个教程并学习python中的Selenium，但是我似乎无法让Selenium使用find_element_by_class或find_element_by_XPATH单击“Add to Cart”按钮。问题是检查项目是否缺货，如果缺货，则刷新网页并重新启动脚本。如果商品有库存，则应单击“添加到购物车”

我正在使用：

Python v3.9

铬v87

这是我正在练习的URL：

这是我当前的点击代码：

# Selenium Tutorial #1

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.action_chains import ActionChains

import time

driver = webdriver.Chrome(r"C:\Users\Ste1337\Desktop\chromedriver\chromedriver.exe")

driver.get("https://www.currys.co.uk/gbuk/tv-and-home-entertainment/televisions/televisions/samsung-ue75tu7020kxxu-75-smart-4k-ultra-hd-hdr-led-tv-10213562-pdt.html")

#search = driver.find_element_by_id(ContentPlaceHolder1_NotifyBtn)

link = driver.find_element_by_id("onetrust-accept-btn-handler")
link.click

try:
    element = WebDriverWait(driver, 10).until(
    EC.presence_of_element_located((By.ID, "onetrust-accept-btn-handler"))
    )
    element.click()
except Exception:
    pass

driver.implicitly_wait(2)

try:
    element = WebDriverWait(driver, 1).until(
    EC.presence_of_element_located((By.XPATH, "email-desktop"))
    )
    time.sleep(1)
    browser.refresh()
except:
    driver.find_element_by_class_name("Button__StyledButton-bvTPUF hZIOeU Button-jyKNMA GZkwS")
    link.click()

Answer 1

不能将多个类传递给find_element_by_class_name。而是使用driver.find_element_by_css_selector或xpath

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.action_chains import ActionChains

import time

driver = webdriver.Chrome(r"C:\Users\Frank\Documents\Python Scripts\chromedriver_win32\chromedriver.exe")

driver.get("https://www.currys.co.uk/gbuk/tv-and-home-entertainment/televisions/televisions/samsung-ue75tu7020kxxu-75-smart-4k-ultra-hd-hdr-led-tv-10213562-pdt.html")

#search = driver.find_element_by_id(ContentPlaceHolder1_NotifyBtn)

try:
    element = WebDriverWait(driver, 10).until(
    EC.presence_of_element_located((By.ID, "onetrust-accept-btn-handler"))
    )
    element.click()
except Exception:
    pass

driver.implicitly_wait(2)

try:
    element = WebDriverWait(driver, 1).until(
    EC.presence_of_element_located((By.XPATH, "email-desktop"))
    )
    time.sleep(5)
    driver.refresh()
except:
    button = driver.find_element_by_css_selector("button.Button__StyledButton-bvTPUF.hZIOeU.Button-jyKNMA.GZkwS")

接下来，如果调用button.is_displayed()，它将返回False，因为它是一个隐藏元素。这意味着您不能使用button.click()与它交互。相反，您可以使用javascript单击按钮

driver.execute_script("arguments[0].click();", button)
