Problem Selecting Okay Button with Python and Selenium

问题

So I have an issue, where I am unable to select the okay from an alert message that pops up in a new window. I don't really know what to make of it and really just want to accept the alert as all of the work has been done to ensure that the removal is processed. The code for the overall script can be found here: https://github.com/Richard-Barrett/ITDataServicesInfra/blob/master/Python/Skyward/Administration/remove_sec_groups_inactive_users.py

Code:

                            EC.element_to_be_clickable((By.XPATH, "//*[@id='msgBtn1']")))
element.click()

A message pops up and looks like this once I hit the Remove All Groups:

I think part of the code is that I am not handling it right because it is not switching to the 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])

Here is a copy of the element I need to click on:

<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>

回答1:

Turned out I didn't need to switch to the window. The alert was part of the main page. I took out the

# 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])

Now the code looks like this and it works just fine:

The easiest way to figure out these issues is to use the Selenium IDE browser plugin. There you can manually walk through the steps of your app, save it, run it to make sure it works. This is all via simply interacting with your webs app (like recording a macro). The beauty of it, it generates the code for you and identifies the CSS / HTML selectors necessary to locate objects to interact (or to locate information to assert for automated testing)
