I'm trying to automate an administration task, so far I have made selenium to click on an element to show a dropdown menu.

enter image description here

When it comes the time to click on one of those menu elements I've got an error saying that the element must be displayed.

Code:

 driver = webdriver.Chrome()
 driver.implicitly_wait(10)
 driver.get(url)
 doc = driver.find_element_by_css_selector('td.ms-vb-title > table')
 try:
    doc.click()
    time.sleep(4)
    menu = driver.find_element_by_xpath('//menu/span[5]')
    time.sleep(4)
    print dir(menu)
    menu.click()
 except:
    traceback.print_exc()
    driver.quit()

Error:

Traceback (most recent call last):
  File "aprobar_docs.py", line 22, in main
    menu.click()
  File "C:\Python27\lib\site-packages\selenium\webdriver\remote\webelement.py",

    self._execute(Command.CLICK_ELEMENT)

    self.error_handler.check_response(response)

, line 147, in check_response
    raise exception_class(message, screen, stacktrace)
ElementNotVisibleException: Message: u'Element must be displayed to click'

As you can see the code waits a lot to get the element loaded. I've also tried to set the element's is_displayed property to True but didn't work neither.

Note: the element that's not displayed is the one on the xpath search, it is present because I've logged it with dir(menu)

Edit:

The menu variable is not the menu itself it's one of the spans that are elements of the menu, doc is the Perfil html element getting clicked to show the dropdown.

Edit 2:

Inspecting the DOM on chrome tools, when you click a doc a new menu gets created on the tree, I don't know if it's because of an ajax call or vanilla js, I don't think it's really that important how it's created. I can't retrieve it from the page and make a python object from it, it's just not being displayed at least on code.

Final Edit:

I ended up executing some JavaScript to make it work. Apparently when Selenium finds the menu item the first element that triggers the menu drop down loses the focus and it makes the menu invisible again, if you don't select a menu item and wait for some time the menu dropdown still is shown, if you try to select one element from the menu the menu disappears.

你为什么不选择这样的选项

el = driver.find_element_by_id('id_of_select')
for option in el.find_elements_by_tag_name('option'):
    if option.text == 'The Options I Am Looking For':
        option.click() # select() in earlier versions of webdriver

如果您的点击没有触发 ajax 调用来填充您的列表，那么您实际上不需要执行点击。

您需要找到目标的链接。您并没有真正单击元素，而是单击链接......（或者更确切地说，您单击其中包含链接的元素）。话虽如此，点击链接最可靠的方法是隔离链接元素。 

frame = driver.find_element_by_id('this_is_your_frame_name') 
links = frame.find_elements_by_xpath('.//a')
links[1].click()

或者，

for link in links:
    if link.text() == "Administratar Permisos":
        link.click()
