I'm trying to change CSS style of an element (example: from "visibility: hidden;" to "visibility: visible;") using selenium .execute_script. (any other method through selenium+python would be accepted gracefully).

my code:

driver = webdriver.Firefox()
driver.get("http://www.example.com")

elem = driver.find_element_by_id('copy_link')

elem.execute_script(  area of my problem )

what do i need to do in order to play with the CSS of the webpage ?

Here is an example without using any jQuery. It will hide Google's logo.

from selenium import webdriver
driver = webdriver.Firefox()
driver.get("http://www.google.com")
driver.execute_script("document.getElementById('lga').style.display = 'none';")

The same idea could be used to show a hidden element by setting .style.display to "block", for example.

thanks, i have tried it only to receive the following error: WebDriverException: Message: u'document.getElementById(...) is null' ; –  user2627775 Jul 28 '13 at 21:04
    
@user2627775, Can you confirm that the element actually exists and is not wrapped in an <iframe>? Look at driver.page_source to see whether the element you wish to show or hide is actually present in the DOM. Also, ensuring that you have the latest version of selenium might be worthwhile. –  ChrisP Jul 29 '13 at 2:25
    
selenium web driver 2.33, and through driver.page_source i did confirm that the element is in the source. (id did: html_source = browser.page_source if "whatever" in html_source: print 'in'. the problematic html is not in <iframe>, it's in a div/div/a/span. could 'bindpoint = "copy_link_wraper"' be the problem? (as in stackoverflow.com/questions/4607582/…) –  user2627775 Jul 29 '13 at 9:44
    
@user2627775, You'll have to edit your post with the website you are trying to scrape and the ID of the div so that we can actually run your code. There is nothing else I can say without seeing the problem myself. –  ChrisP Jul 29 '13 at 12:37

String in execute_script() is JS code you want to run (docs).

If you use jQuery it can be just

driver.execute_script("$('#copy_link').css('visibility', 'visible');")
