python - 触发 .click 动作时触发“TimeoutException”错误

问题描述

我是使用 python 进行 selenium web 自动化的新手，我正在尝试自动化登录页面操作。输入用户名和密码可以正常工作，但是当到达提交它们的点击操作时，会触发以下错误：

 self.driver.find_element_by_xpath("//input[@type='submit']").click()

test_xxxManagement.py:27:

E selenium.common.exceptions.TimeoutException：消息：

/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/selenium/webdriver/remote/errorhandler.py:242：TimeoutException

这是执行的一段代码： def test_Login(self):

    Email = self.driver.find_element_by_id("session_email")
    Email.send_keys("<email>")

    Password = self.driver.find_element_by_id("session_password")
    Password.send_keys("<password>")

    Login_button = self.driver.find_element_by_xpath("//input[@type='submit']")

login_button.click() ##代码点击动作后触发错误

        wait = WebDriverWait(self.driver, 5)
        wait.until(EC.presence_of_element_located(By.ID, "pageTitle"))

I tried to execute the code on both Chrome and Firefox, but wiith the same results.

我究竟做错了什么？

谢谢！

解决方案

您能否在问题中添加包含您尝试单击的元素的 html 行？一个可能的原因可能是按钮被隐藏了，即它具有style="display: hidden;"阻止硒检测到它的属性。

如果是这种情况，请尝试下面的代码段

button_element= self.driver.find_element_by_xpath("//input[@type='submit']")
#This makes the button clickable
self.driver.execute_script("arguments[0].style.display='block'",button_element)
self.driver.find_element_by_xpath("//input[@type='submit']").click()

另一个问题可能是按钮变得模糊或无法与 selenium 一起使用，因为您可以尝试通过 JS 单击它：

#The js click command doesn't care if the button is being obscured by a div element and just force-clicks it.
self.driver.execute_script("arguments[0].click();", button_element)
