python之添加到购物车时 selenium 失败，如何单击 javascript 按钮

这是我正在尝试做的事情的一个片段，它基本上只是将一个项目添加到购物车并使用 Selenium webdriver 转到结帐页面。

        driver.get("http://store.nike.com/us/en_us/pw/mens-tops-t-shirts/7puZobp?ipp=120") 
        driver.find_element_by_xpath("//div[@id='exp-gridwall-wrapper']/div[2]/div[2]/div[2]/div/div/div/div/div/div[3]/div[2]/p").click() 
        size_button = driver.find_element_by_css_selector(".exp-pdp-size-dropdown") 
        actions = ActionChains(driver) 
        actions.move_to_element(size_button).perform() 
        driver.find_element_by_id("buyingtools-add-to-cart-button").click() 
        checkout_button = driver.find_element_by_css_selector(".checkout_button") 
        actions = ActionChains(driver) 
        actions.move_to_element(checkout_button).perform() 

我目前在“单击添加到购物车”步骤中遇到此错误:

   WebDriverException: Message: Element is not clickable 

我相信在那之后的一切也都坏了......

我遇到的问题是识别要点击的正确 css 元素。

如果有人能解释我做错了什么或告诉我要选择的正确元素以便我可以添加到购物车并点击结帐，我们将不胜感激!

请您参考如下方法:

我很确定这是因为您打开了尺寸下拉菜单并且它覆盖了“添加到购物车”按钮。

只需最大化浏览器窗口:

driver.maximize_window() 
driver.get("http://store.nike.com/us/en_us/pw/mens-tops-t-shirts/7puZobp?ipp=120") 
# ... 

另外，您在按钮类名称中有错字 - 它是 checkout-button 而不是 checkout_button。并且，您需要添加 Explicit Waits解决可见性和时间问题:

from selenium import webdriver 
from selenium.webdriver import ActionChains 
from selenium.webdriver.common.by import By 
from selenium.webdriver.support.ui import WebDriverWait 
from selenium.webdriver.support import expected_conditions as EC 
 
 
driver = webdriver.Firefox() 
driver.maximize_window() 
driver.get("http://store.nike.com/us/en_us/pw/mens-tops-t-shirts/7puZobp?ipp=120") 
 
wait = WebDriverWait(driver, 10) 
 
driver.find_element_by_xpath( 
    "//div[@id='exp-gridwall-wrapper']/div[2]/div[2]/div[2]/div/div/div/div/div/div[3]/div[2]/p").click() 
 
# opening size dropdown 
size_button = wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, ".exp-pdp-size-and-quantity-container a.exp-pdp-size-dropdown"))) 
actions = ActionChains(driver) 
actions.move_to_element(size_button).click().perform() 
 
# selecting size 
size = wait.until(EC.visibility_of_element_located((By.XPATH, "//li[contains(@class, 'nsg-form--drop-down--option') and normalize-space(.) = 'S']"))) 
actions = ActionChains(driver) 
actions.move_to_element(size).click().perform() 
 
# adding to cart 
driver.find_element_by_id("buyingtools-add-to-cart-button").click() 
 
# checkout 
checkout_button = wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, ".checkout-button"))) 
actions = ActionChains(driver) 
actions.move_to_element(checkout_button).click().perform() 

对我有用。
