如何使用 Selenium WebDriver for python 在浏览器上打开一个新窗口? [英] How to open a new window on a browser using Selenium WebDriver for python?
问题描述
我正在尝试使用 selenium for python 在浏览器中打开一个新选项卡或一个新窗口.如果打开一个新选项卡或新窗口并不重要，重要的是打开浏览器的第二个实例.
I am attempting to open a new tab OR a new window in a browser using selenium for python. It is of little importance if a new tab or new window is opened, it is only important that a second instance of the browser is opened.
我已经尝试了几种不同的方法，但都没有成功.
I have tried several different methods already and none have succeeded.
切换到一个不存在的窗口，希望在找不到该窗口时打开一个新窗口:
Switching to a window that does not exist with hopes that it would then open a new window upon failure to locate said window:
driver.switch_to_window(None)
遍历打开的窗口(虽然目前只有一个)
Iterating through open windows (although there is currently only one)
for handle in driver.window_handles:
driver.switch_to_window(handle)
尝试模拟键盘按键
Attempting to simulate a keyboard key press
from selenium.webdriver.common.keys import Keys
driver.send_keys(Keys.CONTROL + 'T')
这个问题的特别之处在于，似乎无法将密钥直接发送到浏览器，只能发送到像这样的特定元素:
The problem with this one in particular was that it does not seem possible to send keys directly to the browser, only to a specific element like this:
driver.find_element_by_id('elementID').send_keys(Keys.CONTROL + 'T')
然而，当像这样的命令被发送到一个元素时，它似乎什么都不做.我试图找到页面上最顶层的 HTML 元素并将密钥发送到该元素，但再次遇到失败:
However, when a command such as this is sent to an element, it appears to do absolutely nothing. I attempted to locate the topmost HTML element on the page and send the keys to that, but was again met with failure:
driver.find_element_by_id('wrapper').send_keys(Keys.CONTROL + 'T')
我在网上找到的另一个版本，无法验证其有效性或缺乏有效性，因为我不确定需要导入哪个类/模块
Another version of this I found online, and was not able to verify its validity or lack thereof because I'm not sure what class/module which needs importing
act = ActionChains(driver)
act.key_down(browserKeys.CONTROL)
act.click("").perform()
act.key_up(browserKeys.CONTROL)
一些非常相似但语法不同的东西(我不确定其中一个或两个是否是正确的语法)
Something very similar with different syntax (I'm not sure if one or both of these is correct syntax)
actions.key_down(Keys.CONTROL)
element.send_keys('t')
actions.key_up(Keys.CONTROL)
推荐答案
你做这样的事情怎么样
driver = webdriver.Firefox() #First FF window
second_driver = webdriver.Firefox() #The new window you wanted to open
根据您要与之交互的窗口，相应地发送命令
Depending on which window you want to interact with, you send commands accordingly
print driver.title #to interact with the first driver
print second_driver.title #to interact with the second driver
