Question

我已经尝试了一段时间，但似乎无法使用python硒找到该元素。我使用过的所有方法（无论是通过xpath，css选择器还是通过类找到）都返回否定的，所以有人知道如何查找并单击中间值为“ LOG IN”和类型为“ button”的元素吗？ / p>

firefox_options = webdriver.FirefoxOptions()
driver = webdriver.Firefox(firefox_options=firefox_options)
driver.get('https://www.nike.com/launch/?cp=usns_aff_nike&s=upcoming')
time.sleep(.2)
logIn = driver.find_element_by_css_selector('#root > div > div > div.main-       layout > div > header > div.d-sm-h.d-lg-b > section > ul > li.member-nav-item.d-sm-ib.va-sm-m > button')
logIn.click()
time.sleep(.2)
email = driver.find_element_by_name('emailAddress')
email.send_keys('email')
passWord = driver.find_element_by_name('password')
passWord.send_keys('password')

# Find and click element from above

我似乎找不到它，因此，感谢您的帮助！

在选择登录按钮时，其他所有功能都可以正常工作。这是代码，以防万一他们可能有问题或有人想检查一下，谢谢

Answer 1

要在文本为登录的元素上调用click()，您需要诱使 WebDriverWait 使元素可点击您可以使用以下任一解决方案：

css_selector：

WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "div.nike-unite-submit-button.loginSubmit.nike-unite-component.blurred > input[value='LOG IN']"))).click()

xpath：

WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//div[@class='nike-unite-submit-button loginSubmit nike-unite-component blurred']/input[@value='LOG IN']"))).click()

Answer 2

您可以使用按钮的ID找到该按钮，然后单击它：

button = driver.find_element_by_id('019a8673-60aa-4b9f-825a-00b01ad36507')
button.click()

在这里，驱动程序是您的浏览器网络驱动程序。
