python - How to make Selenium not wait till full page load, which has a slow script?

Question

Selenium driver.get (url) wait till full page load. But a scraping page try to load some dead JS script. So my Python script wait for it and doesn't works few minutes. This problem can be on every pages of a site.

from selenium import webdriver

driver = webdriver.Chrome()
driver.get('https://www.cortinadecor.com/productos/17/estores-enrollables-screen/estores-screen-corti-3000')
# It try load: https://www.cetelem.es/eCommerceCalculadora/resources/js/eCalculadoraCetelemCombo.js 
driver.find_element_by_name('ANCHO').send_keys("100")

How to limit the time wait, block AJAX load of a file, or is other way?

Also I test my script in webdriver.Chrome(), but will use PhantomJS(), or probably Firefox(). So, if some method uses a change in browser settings, then it must be universal.

When Selenium loads a page/url by default it follows a default configuration with pageLoadStrategy set to normal. To make Selenium not to wait for full page load we can configure the pageLoadStrategy. pageLoadStrategy supports 3 different values as follows:

1. normal (full page load)
2. eager (interactive)
3. none

Here is the code block to configure the pageLoadStrategy :

• Firefox :

  from selenium import webdriver
  from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
  
  caps = DesiredCapabilities().FIREFOX
  caps["pageLoadStrategy"] = "normal"  #  complete
  #caps["pageLoadStrategy"] = "eager"  #  interactive
  #caps["pageLoadStrategy"] = "none"
  driver = webdriver.Firefox(desired_capabilities=caps, executable_path=r'C:pathogeckodriver.exe')
  driver.get("http://google.com")
  

• Chrome :

  from selenium import webdriver
  from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
  
  caps = DesiredCapabilities().CHROME
  caps["pageLoadStrategy"] = "normal"  #  complete
  #caps["pageLoadStrategy"] = "eager"  #  interactive
  #caps["pageLoadStrategy"] = "none"
  driver = webdriver.Chrome(desired_capabilities=caps, executable_path=r'C:pathochromedriver.exe')
  driver.get("http://google.com")
  

Note : pageLoadStrategy values normal, eager and none is a requirement as per WebDriver W3C Editor's Draft but pageLoadStrategy value as eager is still a WIP (Work In Progress) within ChromeDriver implementation.
