硒开关标签 [英] Selenium Switch Tabs

问题描述

由于Firefox不再支持该选项卡的Control + T，因此我开始使用 driver.execute_script("window.open('URL'，'new_window')")

Since Firefox does not support Control + T anymore for the tab, I started using driver.execute_script("window.open('URL', 'new_window')")

我试图显示我打开的其他标签的标题并在它们之间进行切换.对于下面的示例，我希望输出为facebook，google并返回至facebook.现在的输出是facebook，facebook和facebook.

I am trying to display the title of the different tab I open and switch between them. For the example below, I expect the output to be facebook, google and back to facebook. Right now the output is facebook, facebook and facebook.

我从这里尝试了答案，但是它也没有用:使用Selenium WebDriver切换回父选项卡

I tried the answer from here but it also did not work: Switch back to parent tab using selenium webdriver

from selenium import webdriver

driver = webdriver.Firefox()
driver.get("http://www.facebook.com/")
print(driver.title)

driver.execute_script("window.open('http://google.com', 'new_window')")
print(driver.title)

driver.switch_to.window(driver.window_handles[0])
print(driver.title)

已更新: 我尝试了以下代码，但仍然无法正常工作.

UPDATED: I tried the follow code and it still did not work.

from selenium import webdriver

driver = webdriver.Firefox()
driver.get("http://www.facebook.com/")
print(driver.title)
window_before = driver.window_handles[0]

driver.execute_script("window.open('http://google.com', 'new_window')")
window_after = driver.window_handles[1]
driver.switch_to.window(window_after)
print(driver.title)

推荐答案

关于Tab/窗口切换/处理的几句话:

A few words about Tab/Window switching/handling:

• 始终跟踪父窗口" 句柄，以便以后根据需要根据需要进行遍历.

• Always keep track of the Parent Window handle so you can traverse back later if required as per your usecase.

始终将 WebDriverWait 与expected_conditions 作为

Always use WebDriverWait with expected_conditions as number_of_windows_to_be(num_windows) before switching between Tabs/Windows.

始终跟踪子窗口句柄，以便您可以在需要时遍历.

Always keep track of the Child Window handles so you can traverse whenever required.

始终将 WebDriverWait 与这是您自己的代码，上面有一些小的调整:

Here is your own code with some minor tweaks mentioned above:

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

driver = webdriver.Firefox(executable_path=r'C:\WebDrivers\geckodriver.exe')
driver.get("http://www.facebook.com/")
print("Initial Page Title is: %s" %driver.title)
windows_before  = driver.current_window_handle
driver.execute_script("window.open('http://google.com')")
WebDriverWait(driver, 10).until(EC.number_of_windows_to_be(2))
windows_after = driver.window_handles
new_window = [x for x in windows_after if x != windows_before][0]
driver.switch_to.window(new_window)
WebDriverWait(driver, 20).until(EC.title_contains("G"))
print("Page Title after first window switching is: %s" %driver.title)
driver.close()
driver.switch_to.window(windows_before)
WebDriverWait(driver, 20).until(EC.title_contains("F"))
print("Page Title after second window switching is: %s" %driver.title)
driver.quit()

控制台输出:

Console Output:

Initial Page Title is: Facebook – log in or sign up
Page Title after first window switching is: Google
Page Title after second window switching is: Facebook – log in or sign up
