从Chrome WebDriver访问getEventListeners(Python) [英] Access getEventListeners from chrome webdriver (python)

问题描述

从Selenium Webdriver获取附加到节点的所有事件

Get all events attached to a node from selenium webdriver

我正在使用Selenium-python，我想执行一个JavaScript脚本(通过 driver.execute_script('my js script').

I'm using selenium-python and I'd like to execute a javascript script (through driver.execute_script('my js script').

此脚本使用 getEventListeners ，该功能仅在 Chrome 上可用.我成功使用了

This script uses getEventListeners which is only available on Chrome. I used successfully

driver = webdriver.Chrome('path/to/chromedriver')

启动Chrome浏览器.用 getEventListeners(myNode)执行我的脚本，我得到类似的东西:

to launch a chrome browser. Executing my script with getEventListeners(myNode) I get something like:

execute_script中的文件"/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py"，第403行{'script':脚本，'args':converted_args})['value']执行中的文件"/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py"，行175self.error_handler.check_response(响应)文件"/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/errorhandler.py"，行166，在check_response中引发exception_class(消息，屏幕，堆栈跟踪)selenium.common.exceptions.WebDriverException:消息:未知错误:未定义getEventListeners

File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 403, in execute_script {'script': script, 'args':converted_args})['value'] File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 175, in execute self.error_handler.check_response(response) File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/errorhandler.py", line 166, in check_response raise exception_class(message, screen, stacktrace) selenium.common.exceptions.WebDriverException: Message: unknown error: getEventListeners is not defined

getEventListeners 可通过命令行API使用，但我无法使其在selenium中起作用.有解决方案吗?还有其他方法可以将所有事件绑定到元素吗?(尤其是Click事件)

getEventListeners is available through the Command Line API but I can't make it work from selenium. Is there a solution for this? Is there any other way to get all events binded to an element ? (especially Click event)

欢呼

推荐答案

不幸的是，答案是:无法通过 ChromeDriver 访问 getEventListeners .如评论所述，这是设计:

Sadly the answer is: Accessing getEventListeners via ChromeDriver is not possible. This is -- as mentioned in the comments -- by design:

警告:仅当您从Chrome DevTools控制台调用这些功能时，这些功能才起作用.如果您尝试在脚本中调用它们，它们将无法工作.

Warning: These functions only work when you call them from the Chrome DevTools Console. They won't work if you try to call them in your scripts.

根据问题报告设置为 WontFix .

但是:

查看此答案，以查找不使用 getEventListeners 附加到节点的所有事件.
