问题描述
我一直在尝试使用 Selenium，并一直试图让我的自动结账工作正常进行。到目前为止，它非常成功，但我遇到了一个障碍，我的代码的最后部分似乎无法正常工作。我试过以我能想到的各种方式安排我的“睡眠”和“隐式等待”，但没有成功。我一直被抛出“selenium.common.exceptions.NoSuchElementException: Message: Unable to locate element: //*[@id="creditCardNumber"]” 如果有人能帮我解决这个问题，我将不胜感激！

问题特别结束。

driver.execute_script("arguments[0].scrollIntoView();",cc_number)
time.sleep(2)
cc_number.send_keys('123456789101112')
解决方法
只需使用 webdriver wait 等待元素弹出并发送密钥即可。
wait.until(EC.element_to_be_clickable((By.ID,"creditCardNumber"))).send_keys("123456789101112")
修复其他代码以使其更稳定。
wait = WebDriverWait(driver,10)
action = webdriver.ActionChains(driver)
def get_nike():
driver.maximize_window()
driver.get('https://www.nike.com/')
men_shoes = wait.until(EC.element_to_be_clickable((By.XPATH,"//a[@aria-label='Men']")))
action.move_to_element(men_shoes).perform()
new_releases = driver.find_element_by_xpath("//a[@role='menuitem' and text()='New Releases']")
action.move_to_element(new_releases).click().perform()
selected_shoes = wait.until(EC.element_to_be_clickable((By.XPATH,"//a[@aria-label='Nike ZoomX Invincible Run Flyknit']//img")))
selected_shoes.click()
get_size = wait.until(EC.element_to_be_clickable((By.XPATH,"//label[text()='US 10.5']")))
get_size.click()
导入
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
使用此代码段检查 WebElement 在视口中是否可见，不要使用 selenium 等待，它们有很多错误。

# function getting data for the last x years with x weeks space from checking data and specific
observation.
def stock_data(ticker,period,interval,observation):
ticker = yf.Ticker(ticker)
ticker_history = ticker.history(period,interval)
print(ticker_history[observation]) #is here to show you the data that we get
date = pd.date_range(ticker_history[period])
x = date
y = np.array(ticker_history[observation])
plt.style.use('dark_background')
plt.plot(x,y)
plt.ylabel('Price($)')
plt.xlabel('Date',rotation=0)
plt.show()
stock_data('GOOGL','6mo','1wk','Open')
只需将 Java 方法转换为 Python 函数并将您要查找的 WebElement 传递给它即可。
