Selenium-从frame [0]切换到window [1]后出现NoSuchElementException-Firefox GeckoDriver错误-Python [英] Selenium - NoSuchElementException after switching from frame[0] to window[1] - Firefox GeckoDriver Error - Python

问题描述

我在Firefox GeckoDriver浏览器中收到错误element not found

I have receive an error, element not found in the Firefox GeckoDriver browser

当我从窗口[1]切换到帧[0]，回到窗口[1]，然后单击关闭帧按钮时.

when i switch from window[1] to frame[0], back to window[1], and then click the close frame button.

我想继续使用GeckoDriver，因为我遇到了ChromeDriver的性能问题.抱歉，这是一个内部网站，我不能分享HTML.

I want to continue using GeckoDriver because i was having performance issues with ChromeDriver. Sorry this is an internal website and I can't share the HTML.

1. 我已完成以下操作以查明问题所在.
   • 使用完全相同的代码进行测试，并且可以在Chrome驱动程序中正常工作
   • 当我切换到window [1]时，在Firefox中工作，单击openframe按钮，然后单击closeframe按钮，而不切换到frame [0].
   • 我可以切换到帧[0]，切换回window [1]并执行driver.close()，它将关闭window [1].
   • 从帧[0]切换回后，我可以从window [1]读取driver.page_source，并且看到该元素仍在page_source中并且没有更改.
   • 我可以从帧[0]切换回窗口[0]，然后单击按钮重新打开窗口[1]，这样可以正常工作.然后，我可以单击打开和关闭框架按钮.

1. I have done the following to pinpoint the issue.
   • Tested with exact same code and works properly in Chrome driver
   • Works in Firefox when i switch to window[1] click the openframe button, and then click the closeframe button, without switching to frame[0].
   • I can switch to frame[0], switch back to window[1] and do a driver.close() and it will close window[1].
   • I can read the driver.page_source from window[1] after switching back from frame[0] and see that the element is still in the page_source and has not changed.
   • I can switch from frame[0] back to window[0] and click the button to re-open window[1] and that works properly. Then i can click the open and close frame buttons.

因此问题仅在于从frame [0]切换回window [1]，然后尝试在Firefox GeckoDriver中单击window [1]中的元素.

So the problem just resides on switching from frame[0] back to window[1], then trying to click an element in window[1] in Firefox GeckoDriver.

Python:2.7
硒:3.0.1
GeckoDriver:v0.13.0
Firefox:51.0.1

Python: 2.7
Selenium: 3.0.1
GeckoDriver: v0.13.0
Firefox: 51.0.1

这是代码:

firefox_capabilities = DesiredCapabilities.FIREFOX
firefox_capabilities['marionette'] = True
driver = webdriver.Firefox(capabilities=firefox_capabilities)
driver.get('www.internalwebsite.com')
driver.find_element_by_id('opensnewwindow').click()
driver.switch_to_window(driver.window_handles[1])
driver.find_element_by_id('opennewframe').click()
driver.switch_to_frame(0)
//read contents
driver.switch_to_window(driver.window_handles[1])
driver.find_element_by_id('closeframe').click()

错误:

selenium.common.exceptions.NoSuchElementException:消息:无法找到元素:[id ="closeframe"]

selenium.common.exceptions.NoSuchElementException: Message: Unable to locate element: [id="closeframe"]

推荐答案

下面的代码似乎可以解决问题.仍然不确定为什么.

The code below seemed to do the trick. Still not sure why though.

driver.switch_to.default_content()

firefox_capabilities = DesiredCapabilities.FIREFOX
firefox_capabilities['marionette'] = True
driver = webdriver.Firefox(capabilities=firefox_capabilities)
driver.get('www.internalwebsite.com')
driver.find_element_by_id('opensnewwindow').click()
driver.switch_to_window(driver.window_handles[1])
driver.find_element_by_id('opennewframe').click()
driver.switch_to_frame(0)
//read contents
driver.switch_to.default_content()
driver.switch_to_window(driver.window_handles[1])
driver.find_element_by_id('closeframe').click()
