Answer 1

Mechanize cannot handle javascript and popup windows:

• How do I use Mechanize to process JavaScript?
• Mechanize and Javascript

To accomplish the goal, you need to utilize a real browser, headless or not. This is where selenium would help. It has a built-in support for popup dialogs:

Selenium WebDriver has built-in support for handling popup dialog boxes. After you’ve triggerd and action that would open a popup, you can access the alert with the following:

alert = driver.switch_to_alert()

Example (using this jsfiddle):

from selenium import webdriver

url = "http://fiddle.jshell.net/ebkXh/show/"
driver = webdriver.Firefox()
driver.get(url)

button = driver.find_element_by_xpath('//button[@type="submit"]')

# dismiss
button.click()
driver.switch_to.alert.dismiss()

# accept
button.click()
driver.switch_to.alert.accept()
