Selenium Python - 处理没有这样的元素异常

I am writing automation test in Selenium using Python. One element may or may not be present. I am trying to handle it with below code, it works when element is present. But script fails when element is not present, I want to continue to next statement if element is not present.

我正在使用Python在Selenium中编写自动化测试。可能存在或不存在一个元素。我试图用下面的代码来处理它，它在元素存在时起作用。但是当元素不存在时脚本失败，如果元素不存在，我想继续下一个语句。

try:
       elem = driver.find_element_by_xpath(".//*[@id='SORM_TB_ACTION0']")
       elem.click()
except nosuchelementexception:
       pass

Error -

错误 -

selenium.common.exceptions.NoSuchElementException: Message: Unable to locate element:{"method":"xpath","selector":".//*[@id='SORM_TB_ACTION0']"}

4 个解决方案

#1

You can see if the element exists and then click it if it does. No need for exceptions. Note the plural "s" in .find_elements_*.

您可以查看元素是否存在，然后单击它（如果存在）。无需例外。注意.find_elements_ *中的复数“s”。

elem = driver.find_elements_by_xpath(".//*[@id='SORM_TB_ACTION0']")
if len(elem) > 0
    elem[0].click()

#2

the way you are doing it is fine.. you are just trying to catch the wrong exception. It is named NoSuchElementException not nosuchelementexception

你这样做的方式很好..你只是想抓住错误的例外。它被命名为NoSuchElementException而不是nosuchelementexception

#3

Are you not importing the exception?

你没有导入例外吗？

from selenium.common.exceptions import NoSuchElementException

try:
    elem = driver.find_element_by_xpath(".//*[@id='SORM_TB_ACTION0']")
    elem.click()
except NoSuchElementException:  #spelling error making this code not work as expected
    pass

Why not simplify and use logic like this? No exceptions needed.

为什么不简化和使用这样的逻辑？无需例外。

if elem.is_displayed():
    elem.click()
