如何在 splinter webdriver python 中切換到窗口或選項卡？

Question

我是 python 和 splinter 的新手。 我閱讀了關於 splinter 的文檔，但它沒有提到 selenium 庫中關於 switch_to 的任何內容。

當我運行此代碼時，出現錯誤。

  from splinter import Browser

  browser = Browser("firefox")
  browser.visit('http://google.com')
  window1 = browser.windows[0] #google
  browser.execute_script("window.open('https://www.amazon.com/');")
  window2 = window1.next #amazon active window
  browser.driver.switch_to.window(window1) #switch back to google

文檔- http://splinter.readthedocs.io/en/latest/browser.html

錯誤：

歡迎任何想法。 謝謝！

試試這個（它的工作）：

# Get parent window
 parent_window = self.browser.driver.current_window_handle
# Open new page in child window
self.browser.driver.execute_script("window.open('http://google.com')")
 # Get list of all windows currently opened (parent + child)
 all_windows = self.browser.driver.window_handles
 # Get child window
 child_window = [window for window in all_windows if window != parent_window][0]
 # Switch to child window
 self.browser.driver.switch_to.window(child_window)
 # Close child window
 self.browser.driver.close()
 # Return to parent window
 self.browser.driver.switch_to.window(parent_window)
