Selenium get_attribute() 返回的值始终为 1

Question

我正在做一些业余的网络抓取，但在通过 xpath 获取值时遇到了问题。我的目标是 https://kek.tools/t/0x4e15361fd6b4bb609fa63c81a2be19d873717870。我的代码如下所示：

def scrape_price():
    options = Options()
    options.headless = True
    options.add_argument("--window-size=1920,1200")
    driver = webdriver.Chrome(options=options, executable_path=DRIVER_PATH)
    driver.get('https://kek.tools/t/0x841fad6eae12c286d1fd18d1d525dffa75c7effe')
    driver.implicitly_wait(100)
    price = driver.find_element_by_xpath('//input[@class="sc-ciSkZP sc-bjHqKj bwSYJA dbQnLk" and @tabindex="2"]')
    print(price.get_attribute("value"))
    driver.quit()

在检查元素中，//input[@class="sc-ciSkZP sc-bjHqKj bwSYJA dbQnLk" and @tabindex="2"] 过滤似乎得到了我需要的准确输入字段，但是当我打印值时总是返回“1”。 WebElement 我使用的方法不对吗？

Answer 1

而不是 implicitly_wait 尝试使用 expected_conditions，如下所示：

from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
def scrape_price():
    options = Options()
    options.headless = True
    options.add_argument("--window-size=1920,1200")
    driver = webdriver.Chrome(options=options, executable_path=DRIVER_PATH)
    wait = WebDriverWait(driver, 20)
    driver.get('https://kek.tools/t/0x841fad6eae12c286d1fd18d1d525dffa75c7effe')
    price = wait.until(EC.visibility_of_element_located((By.XPATH, '//input[@class="sc-ciSkZP sc-bjHqKj bwSYJA dbQnLk" and @tabindex="2"]')))
    print(price.get_attribute("value"))
    driver.quit()

Selenium get_attribute() 返回的值始终为 1

Value being returned by Selenium get_attribute() is always 1

python

selenium

xpath

web-scraping
