在硒中控制Firefox的标签 [英] Controlling firefox tabs in selenium

问题描述

根据 window_handles
lockquote

window_handles

返回当前会话中所有窗口的句柄。

但是，我看不到新的句柄在 window_handles 列表中打开一个新标签：

 >> > from selenium import webdriver 
>>> from selenium.webdriver.common.keys import Keys 
>>> 
>>> driver = webdriver.Firefox（）
>>> driver.get（http://stackoverflow.com/）
>>> driver.window_handles 
 [u'{caca92e1-521e-9b4d-9374-00af0ae7d384}'] 
>>> 
>>> ＃打开一个新标签
>>> send_keys（Keys.COMMAND +'t'）
>>> driver.find_element_by_tag_name（body driver.window_handles 
 [u'{caca92e1-521e-9b4d-9374-00af0ae7d384}'] 
  

<正如你所看到的， window_handles 具有相同的值，但是我在浏览器中看到了两个标签页。这是我做错了什么吗？如果是的话，我应该如何获得新选项卡的句柄？

使用：

• selenium 2.44.0（latest）


• firefox 35.0（latest）
  
• python 2.7.6

请注意，如果我在Chrome中做类似的事情， window_handles 会显示2个句柄：

 >>> driver = webdriver.Chrome（）
>>> driver.get（http://stackoverflow.com/）
>>> driver.execute_script（'window.open（about：blank，_blank）;'）
>>> driver.window_handles 
 [u'CDwindow-9458E5DB-D5ED-496C-BEE7-2FA468F3DF42'，u'CDwindow-04C0FBBC-C418-465B-B6AF-F72B288B45C6'] 
  

解决方案

只有顶级浏览器窗口才有HWND。标签没有自己的HWND。有关更多说明，请参阅此处。

According to the window_handles documentation:

window_handles

Returns the handles of all windows within the current session.

But, I cannot see the new handle appearing in window_handles list after opening a new tab:

>>> from selenium import webdriver
>>> from selenium.webdriver.common.keys import Keys
>>>
>>> driver = webdriver.Firefox()
>>> driver.get("http://stackoverflow.com/")
>>> driver.window_handles
[u'{caca92e1-521e-9b4d-9374-00af0ae7d384}']
>>>
>>> # open a new tab
>>> driver.find_element_by_tag_name("body").send_keys(Keys.COMMAND + 't')
>>> driver.window_handles
[u'{caca92e1-521e-9b4d-9374-00af0ae7d384}']

As you can see, window_handles has the same value, but I see 2 tabs opened in the browser. Is it something I am doing wrong? If yes, how should I obtain the handle of the new tab?

Using:

• selenium 2.44.0 (latest)
• firefox 35.0 (latest)
• python 2.7.6

Note that if I would make a similar thing in Chrome, window_handles would show 2 handles:

>>> driver = webdriver.Chrome()
>>> driver.get("http://stackoverflow.com/")
>>> driver.execute_script('window.open("about:blank", "_blank");')
>>> driver.window_handles
[u'CDwindow-9458E5DB-D5ED-496C-BEE7-2FA468F3DF42', u'CDwindow-04C0FBBC-C418-465B-B6AF-F72B288B45C6']

解决方案

Only the top level browser window has an HWND. Tabs don't have their own HWNDs. For more clarification refer here.
