Executing a script in selenium python

Find the element with selenium and pass it to execute_script() to click:

link = browser.find_element_by_xpath('//div[@class="vbseo_liked"]/a[contains(@onclick, "return vbseoui.others_click(this)")]')
browser.execute_script('arguments[0].click();', link)

Since I know the context of the problem, here is the set of things for you to do to solve it:

• click on the "11 others" link via javascript relying on the solution provided here: How to simulate a click with JavaScript?

• make a custom expected condition to wait for the element text not to ends with "11 others like this." text (this is a solution to the problem you had at Expected conditions with selenium):

  class wait_for_text_not_to_end_with(object):
      def __init__(self, locator, text):
          self.locator = locator
          self.text = text
  
      def __call__(self, driver):
          try :
              element_text = EC._find_element(driver, self.locator).text.strip()
              return not element_text.endswith(self.text)
          except StaleElementReferenceException:
              return False
  

Implementation:

from selenium import webdriver
from selenium.common.exceptions import StaleElementReferenceException
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC


class wait_for_text_not_to_end_with(object):
    def __init__(self, locator, text):
        self.locator = locator
        self.text = text

    def __call__(self, driver):
        try :
            element_text = EC._find_element(driver, self.locator).text.strip()
            return not element_text.endswith(self.text)
        except StaleElementReferenceException:
            return False


browser = webdriver.PhantomJS()
browser.maximize_window()
browser.get("http://www.jamiiforums.com/kenyan-news/225589-kenyan-and-tanzanian-surburbs.html")

username = browser.find_element_by_id("navbar_username")
password = browser.find_element_by_name("vb_login_password_hint")

username.send_keys("MarioP")
password.send_keys("codeswitching")

browser.find_element_by_class_name("loginbutton").click()

wait = WebDriverWait(browser, 30)
wait.until(EC.visibility_of_element_located((By.XPATH, '//h2[contains(., "Redirecting")]')))
wait.until(EC.title_contains('Kenyan & Tanzanian'))
wait.until(EC.visibility_of_element_located((By.ID, 'postlist')))

# click "11 others" link
link = browser.find_element_by_xpath('//div[@class="vbseo_liked"]/a[contains(@onclick, "return vbseoui.others_click(this)")]')
link.click()
browser.execute_script("""
function eventFire(el, etype){
  if (el.fireEvent) {
    el.fireEvent('on' + etype);
  } else {
    var evObj = document.createEvent('Events');
    evObj.initEvent(etype, true, false);
    el.dispatchEvent(evObj);
  }
}

eventFire(arguments[0], "click");
""", link)

# wait for the "div" not to end with "11 others link this."
wait.until(wait_for_text_not_to_end_with((By.CLASS_NAME, 'vbseo_liked'), "11 others like this."))

print 'success!!'
browser.close()
