Selenium's WebDriver.execute_script() returns 'None'

Question

My program is having trouble getting an existing class from a webpage using Selenium. It seems that my WebDriver.execute_script function is not working.

import urllib
from selenium import webdriver

#Path to the chromedriver is definitely working fine.
path_to_chromedriver = 'C:\Users\Ben\Desktop\Coding\FreeFoodFinder\chromedriver.exe'
browser = webdriver.Chrome(executable_path = path_to_chromedriver)
url = 'http://www.maidservicetexas.com/'
browser.implicitly_wait(30)
browser.get(url)
content = browser.execute_script("document.getElementsByClassName('content')");
#Just printing the first character of the returned content's toString for now. Don't want the whole thing yet.
#Only ever prints 'N', the first letter of 'None'...so obviously it isn't finding the jsgenerated content even after waiting.
print content

My program returns 'None,' which tells me that the javascript function is not returning a value/being executed. Chrome's web dev tools tell me that 'content' is certainly a valid class name. The webpage isn't even dynamically generated (my eventual goal is to scrape dynamic content, which is why I make my WebDriver wait for 30 seconds before running the script.)

Answer 1

Return the value:

content = browser.execute_script("return document.getElementsByClassName('content');");
