需要找到元素與硒，得到一個錯誤無法找到具有類名稱的元素

我需要從頁面中刪除信息（編輯：刪除NSFW鏈接）頁面。在進入頁面之前，我需要點擊一個按鈕才能獲取頁面本身。 Im使用Python 2.7.10和硒，與PhantomJS 1.9.8。需要找到元素與硒，得到一個錯誤無法找到具有類名稱的元素

繼承人我的代碼：

#!/bin/env/python 
# -*- coding: cp1250 -*- 
import urllib 
import urllib2 
import time 
from bs4 import BeautifulSoup 
import sys, os 
from selenium.webdriver.support.wait import WebDriverWait 
from selenium import webdriver 

reload(sys) 
sys.setdefaultencoding("cp1250") 

base_url = "https://www.24dolores.pl/" 
waiting_time = 20 

def get_browser(): 
    return webdriver.PhantomJS("phantomjs.exe") 

def download_page_src(url): 
    try: 
     browser = get_browser() 
     wait = WebDriverWait(browser, 30) 
     browser.get(url) 
     time.sleep(5) 
     close = browser.find_element_by_class_name('.enter_pl') 
     close.click() 
     html = browser.page_source 
     browser.close() 
     return html 
    except urllib2.HTTPError, error: 
     return error 
    except urllib2.URLError, error: 
     return error 
    except Exception, error: 
     return error 

page = download_page_src(base_url) 
print page

它給人的錯誤：

Srsly？ NSFW鏈接？這只是我需要的數據來源...爲什麼downvote？ – darias

只需卸下類名稱的點。如果你想繼續使用CSS選擇器，你可以這樣做：

driver.find_element_by_css_selector(".enter_pl")

的錯誤是一樣的，順便說一句，那裏有像'get_element_by_css_selector'，其'find_element_by_css_selector' – darias

查找，而不是讓，是我不好 –

無論如何，這是行不通的 – darias
