如何使用Selenium和Python查找并单击元素以登录

Question

我无法找到并单击元素。HTML如下：

<button _ngcontent-c2=""> INICIAR SESIÓN </button>

我试着用代码：

^{pr2}$

这是我得到的错误：

Traceback (most recent call last):

Answer 1

由于元素是Angular元素，要在文本为INICIAR SESIÓN的元素上click()，您需要为element_to_be_clickable()归纳WebDriverWait，并且可以使用以下Locator Strategy：

• 使用XPATH：

  driver.execute_script("arguments[0].click();",WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//button[contains(., 'INICIAR SESIÓN')]"))))
  

• 注意：您必须添加以下导入：

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

Answer 2

尝试下列操作xpath

login_element = driver.find_element_by_xpath("//button[contains(.,'INICIAR')]"
login_element.click()

已编辑

似乎webdriver无法单击按钮元素.注入java脚本执行器单击按钮元素或使用action类单击。在

^{pr2}$

或者动作类。在

login_element = driver.find_element_by_xpath("//button[contains(.,'INICIAR SESIÓN')]")
ActionChains(driver).move_to_element(login_element).click().perform()

对action类使用以下导入。在

from selenium.webdriver.common.action_chains import ActionChains
