Python硒按类选择元素

Question

我试图选择一种含有硒的元素，但我是一个初学者。

以下是我尝试选择的元素：

<button type="submit" class="btn btn-primary btn-block btn-form">
    Connexion
</button>

我在我的脚本上尝试了这几行：

from selenium import webdriver

driver = webdriver.Chrome(executable_path="chromedriver.exe")
driver.get("https://skysand.fr")

connexion_button = driver.find_element_by_class_name("login")
connexion_button.click()

email_input = driver.find_element_by_id("email")
email_input.send_keys("XXXX")

password_input = driver.find_element_by_id("password")
password_input.send_keys("XXXX")

connect_button = driver.find_element_by_class_name("btn-primary btn-block btn-form")
connect_button.click()

但它不工作：（

硒.common.exceptions.Element单击异常异常：消息：元素单击被截获：元素在点上不可单击 （513， 955）

谢谢你，如果你能帮助我！（抱歉我的英语不好...

Answer 1

为了通过多个类名选择元素，应使用 css_selector 或 XPath。另外，对于此元素，最好使用此 css 定位符：

button[type='submit']

所以试试这个：

connect_button = driver.find_element_by_css_selectro("button[type='submit']")
connect_button.click()

此外，您的代码需要等待。它们看起来会是这样的:

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

wait = WebDriverWait(driver, 20)

driver = webdriver.Chrome(executable_path="chromedriver.exe")
driver.maximize_window()
driver.get("https://skysand.fr")

wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, ".login"))).click()

wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, "#email"))).send_keys("XXXX")

wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, "#password"))).send_keys("XXXX")

wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, "button[type='submit']"))).click()
