Question

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。

    cc_number.send_keys('123456789101112')

Answer 1

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

Answer 2

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。

import numpy as np
import yfinance as yf
import matplotlib.pyplot as plt
import pandas as pd

# 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。
