使用Python和Selenium选择“确定”按钮的问题

Question

因此，我无法从在新窗口中弹出的警报消息中选择okay。我真的不知道该怎么做，实际上只是想接受警报，因为已完成所有工作以确保删除已得到处理。整个脚本的代码可以在这里找到：https://github.com/Richard-Barrett/ITDataServicesInfra/blob/master/Python/Skyward/Administration/remove_sec_groups_inactive_users.py

弹出消息，当我点击“删除所有组”时，看起来像这样：

我认为部分代码是我没有正确处理它，因为它没有切换到Window：

# Browser Switches to New Window Alert for Verification
# Browser Switches to Window
WebDriverWait(browser,10).until(EC.number_of_windows_to_be(2))
browser.switch_to.window(browser.window_handles[-1])

这里是我需要单击的元素的副本：

<a class="button" id="msgBtn1" tabindex="5" href="javascript:if (cbs('msgBtn1')) {closeMessage(false); validateForm('xAllGroups','ssusrhttp001.w','ssusrbrws001.w'); cancelEvent();}" role="button" style="width: 100px; font-weight: normal;">OK&nbsp;</a>

Answer 1

原来我不需要切换到窗口。该警报是主页的一部分。我拿出

# Browser Switches to New Window Alert for Verification
# Browser Switches to Window
WebDriverWait(browser,10).until(EC.number_of_windows_to_be(2))
browser.switch_to.window(browser.window_handles[-1])

现在代码看起来像这样，它可以正常工作：
