I am working on a web application, in which clicking on some link another popup windows appears. The pop windows is not an alert but its a form with various fields to be entered by user and click "Next".
如何使用 selenium 处理/自动化这个弹出窗口.
How can I handle/automate this popup windows using selenium.
总结:-

- 用户注册表单显示为弹出窗口
- 一个数据由用户填写
- 点击下一步/提交按钮.
- 另一个下一个重定向到另一个页面/表单用户个人信息页面"

推荐答案
切换到弹出窗口具有挑战性，至少有两个不同的原因:
Switching to a popup is challenging for at least two separate reasons:
- 很多人都知道的，就是在弹窗出现的时候需要同时使用
driver.switch_to.window(window_handle)，这样才能在弹窗中找到元素，和弹出窗口关闭后，您可以在主窗口中找到元素. - 只有机器慢的人可能会遇到的情况，就是当 Selenium 将窗口句柄作为变量提供时，它最初设置为 None，并且需要一点时间才能填充一个值.
- The one that many people know, which is that you need to use
driver.switch_to.window(window_handle)both when the popup appears, so that you can find elements in the popup window, and after the popup is closed, so that you can find elements back in the main window. - The one that only people with slow machines are likely to encounter, which is that when Selenium makes a window handle available as a variable, it's initially set to None, and takes a little while before it's filled in with a value.
这里有一些代码可以在执行您请求的序列时解决这些问题.我省略了 import 语句，并且使用了我希望显而易见的变量名.另外，请注意，我喜欢在我的代码中使用 find_element(s)_by_xpath；随意使用其他 find_element(s)_by 方法:
Here's some code that addresses those issues while carrying out your requested sequence. I'm leaving out the import statements, and I'm using variable names that I hope are obvious. Also, note that I like to use find_element(s)_by_xpath in my code; feel free to use other find_element(s)_by methods:
main_window_handle = None
while not main_window_handle:
main_window_handle = driver.current_window_handle
driver.find_element_by_xpath(u'//a[text()="click here"]').click()
signin_window_handle = None
while not signin_window_handle:
for handle in driver.window_handles:
if handle != main_window_handle:
signin_window_handle = handle
break
driver.switch_to.window(signin_window_handle)
driver.find_element_by_xpath(u'//input[@id="id_1"]').send_keys(user_text_1)
driver.find_element_by_xpath(u'//input[@value="OK"]').click()
driver.find_element_by_xpath(u'//input[@id="id_2"]').send_keys(user_text_2)
driver.find_element_by_xpath(u'//input[@value="OK"]').click()
driver.switch_to.window(main_window_handle) #or driver.switch_to_default_content()
如果有人(可能是我)需要在示例中添加更多内容或提供其他信息以使其更清晰，请告诉我.
Please let me know if someone (maybe me) needs to add more to the example, or provide other info, to make it more clear.
