在Python中使用Selenium单击下拉列表时出现问题

Question

I am trying to save the page as entire html using selenium, page has a dropdown list in it. There are 2 elements in that list and I want to save the entire html after clicking each of them.

Below is the code I am using:

    devlink='http://www.t-mobile.com/content/tmo-wem/en/index/cell-phones/nokia-lumia-521.html'
    devname= devlink[devlink.rfind("/")+1:]
    ignore_tags=('script','noscript','style')
    with contextlib.closing(webdriver.Firefox()) as browser:
        browser.get(devlink) # Load page
        dropdown = browser.find_element_by_class_name('dropdown-menu')
        elements = dropdown.find_elements_by_tag_name('li')
        i=0
        for element in elements:
            element.click()
            i = i+1
            time.sleep(2)
            content=browser.page_source
            cleaner=clean.Cleaner()
            content=cleaner.clean_html(content)    
            with open(str(i)+devname,'w') as f:
               f.write(content.encode('utf-8'))

This code is giving me a error, traceback of which looks like this Traceback (most recent call last): File "D:\\Windows Phone\\Pricing\\August\\2013-08-05\\tmo test\\tmo_us_selenium.py", line 52, in <module> element.click() File "C:\\Python27\\lib\\site-packages\\selenium-2.33.0-py2.7.egg\\selenium\\webdriver\\remote\\webelement.py", line 54, in click self._execute(Command.CLICK_ELEMENT) File "C:\\Python27\\lib\\site-packages\\selenium-2.33.0-py2.7.egg\\selenium\\webdriver\\remote\\webelement.py", line 228, in _execute return self._parent.execute(command, params) File "C:\\Python27\\lib\\site-packages\\selenium-2.33.0-py2.7.egg\\selenium\\webdriver\\remote\\webdriver.py", line 165, in execute self.error_handler.check_response(response) File "C:\\Python27\\lib\\site-packages\\selenium-2.33.0-py2.7.egg\\selenium\\webdriver\\remote\\errorhandler.py", line 158, in check_response raise exception_class(message, screen, stacktrace) ElementNotVisibleException: Message: u'Element is not currently visible and so may not be interacted with' ; Stacktrace: at fxdriver.preconditions.visible (file:///c:/users/abhina~1.tal/appdata/local/temp/tmpwnu8em/extensions/fxdriver@googlecode.com/components/command_processor.js:7736) at DelayedCommand.prototype.checkPreconditions_ (file:///c:/users/abhina~1.tal/appdata/local/temp/tmpwnu8em/extensions/fxdriver@googlecode.com/components/command_processor.js:10437) at DelayedCommand.prototype.executeInternal_/h (file:///c:/users/abhina~1.tal/appdata/local/temp/tmpwnu8em/extensions/fxdriver@googlecode.com/components/command_processor.js:10456) at DelayedCommand.prototype.executeInternal_ (file:///c:/users/abhina~1.tal/appdata/local/temp/tmpwnu8em/extensions/fxdriver@googlecode.com/components/command_processor.js:10461) at DelayedCommand.prototype.execute/< (file:///c:/users/abhina~1.tal/appdata/local/temp/tmpwnu8em/extensions/fxdriver@googlecode.com/components/command_processor.js:10401) Traceback (most recent call last): File "D:\\Windows Phone\\Pricing\\August\\2013-08-05\\tmo test\\tmo_us_selenium.py", line 52, in <module> element.click() File "C:\\Python27\\lib\\site-packages\\selenium-2.33.0-py2.7.egg\\selenium\\webdriver\\remote\\webelement.py", line 54, in click self._execute(Command.CLICK_ELEMENT) File "C:\\Python27\\lib\\site-packages\\selenium-2.33.0-py2.7.egg\\selenium\\webdriver\\remote\\webelement.py", line 228, in _execute return self._parent.execute(command, params) File "C:\\Python27\\lib\\site-packages\\selenium-2.33.0-py2.7.egg\\selenium\\webdriver\\remote\\webdriver.py", line 165, in execute self.error_handler.check_response(response) File "C:\\Python27\\lib\\site-packages\\selenium-2.33.0-py2.7.egg\\selenium\\webdriver\\remote\\errorhandler.py", line 158, in check_response raise exception_class(message, screen, stacktrace) ElementNotVisibleException: Message: u'Element is not currently visible and so may not be interacted with' ; Stacktrace: at fxdriver.preconditions.visible (file:///c:/users/abhina~1.tal/appdata/local/temp/tmpwnu8em/extensions/fxdriver@googlecode.com/components/command_processor.js:7736) at DelayedCommand.prototype.checkPreconditions_ (file:///c:/users/abhina~1.tal/appdata/local/temp/tmpwnu8em/extensions/fxdriver@googlecode.com/components/command_processor.js:10437) at DelayedCommand.prototype.executeInternal_/h (file:///c:/users/abhina~1.tal/appdata/local/temp/tmpwnu8em/extensions/fxdriver@googlecode.com/components/command_processor.js:10456) at DelayedCommand.prototype.executeInternal_ (file:///c:/users/abhina~1.tal/appdata/local/temp/tmpwnu8em/extensions/fxdriver@googlecode.com/components/command_processor.js:10461) at DelayedCommand.prototype.execute/< (file:///c:/users/abhina~1.tal/appdata/local/temp/tmpwnu8em/extensions/fxdriver@googlecode.com/components/command_processor.js:10401)

Answer 1

Selenium 2.33 supports Firefox 21 and older. You will have to wait for the Selenium update to have it support FF 22. Refer to this thread for further details. There are many threads on google that discuss similar issues with Selenium 2.33 and FF 22
