Python 3.x Python selenium.common.exceptions.NoSuchElementException:消息：没有这样的元素：无法定位元素

在网站中，我想访问“谁选择退出”字段。使用post的逻辑，我尝试了以下代码 第1版：

 ele2 = driver.find_element_by_xpath("//select[@id='Identity']/option[@value='Myself']") 
    driver.execute_script("arguments[0].click()",ele2)

第2版：

驱动程序。通过xpath（//select[@id='Identity']/option[@value='myelf']）查找元素。单击（）

我得到的错误是：

    acxiom_DD_formfill(title, firstname, middlename, lastname, suffix, email)

谢谢你的帮助

以下是正确的xpath

//select[@name='Identity']/option[@value = 'Submitter']

屏幕截图：

值

属性值是

提交者

而不是

我自己

，它是选项节点的文本。这就是为什么会出现错误

ele = driver.find_element_by_xpath("//select[@name='Identity']/option[@value = 'Submitter']")
driver.execute_script("arguments[0].click()",ele) # using js click so that item will be selected though it's not visible.

请参考下面的解决方案从下拉框中选择值。您可以传递选项值并使用下拉菜单选择它

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
driver = webdriver.Chrome("C:\New folder\chromedriver.exe")

driver.get("https://isapps.acxiom.com/optout/optout.aspx#section8")

WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.XPATH, "//select[@id='Identity']/option[contains(text(),'Who is opting out?')]"))).click();

检查

//select[@id='Identity']/选项[@value='myelf']

xpath是否在chrome开发工具中工作。您可以参考post了解如何在devtools中检查xpath/css。谢谢，所以版本2似乎适合您，但它会为我产生上面的错误。你知道我如何用我的代码解决这个问题吗？

//select[@id='Identity']/option[@value='myelf']

正在使用XPath 1.0，因此你应该会看到相同的行为。请检查下面的答案。谢谢，这很有效！那么，我怎么能让selenium选择“我自己”选项呢？@datasciencelearner:如果它对您有效，您可以点击upvote按钮吗？
