  <pre><code>import unittest, time, re
  
  class Sel(unittest.TestCase):
      def setUp(self):
          self.driver = webdriver.Chrome()
          self.driver.implicitly_wait(30)
          self.verificationErrors = []
          self.accept_next_alert = True
      def test_sel(self):
          driver = self.driver
          delay = 3
          driver.get("https://www.facebook.com")
          elem = driver.find_element_by_name("email")
          elem.clear()
          elem.send_keys("")
  
          elem2 = driver.find_element_by_name("pass")
          elem2.clear()
          elem2.send_keys("")
          elem2.send_keys(Keys.RETURN)
          for i in range(1,100):
              self.driver.execute_script("window.scrollTo(0, document.body.scrollHeight);")
              time.sleep(4)
          html_source = driver.page_source
          data = html_source.encode('utf-8')
          print(data)
  
  
  if __name__ == "__main__":
      unittest.main()
  </code></pre>
  
  <p>But I don't want to make a loop, rather I would want to trigger an event like, If user manually presses the load more posts button, the new page is loaded and I get page source of the page. Is there any way to do that? Any help would be appreciated.</p>
