Python单击带有硒的Js链接

Question

我已测试网页抓取：http://www.guiadosquadrinhos.com/todas-capas-disponiveis

我需要在分页中导航以获取收藏的信息页面。 我需要点击链接 javascript 下一页：

javascript:__doPostBack('ctl00$MainContent$lstProfileView$dataPagerNumeric2$ctl02$ctl00')

from selenium import webdriver
import time

driver = webdriver.PhantomJS(executable_path='C:\Python27\Tools\phantomjs\phantomjs.exe')
driver.get("http://www.guiadosquadrinhos.com/todas-capas-disponiveis")
#print(driver.find_elements_by_class_name("numero_capinha")[0].text)
#driver.find_elements_by_class_name("next_last")[0].click()
#time.sleep(5)
print(driver.find_elements_by_class_name("numero_capinha")[0].text)
driver.find_elements_by_class_name("next_last")[0].click()
print(driver.find_elements_by_class_name("numero_capinha")[0].text)

我的代码返回：

sobreontem - 独立

Traceback（最近一次调用最后一次）：文件“teste_selenium.py”，第 10 行，在 driver.find_elements_by_class_name("next_last")[0].click() 文件 "C:\Python27\lib\site-packages\selenium\webdriver\remote\webelement.py", 第 74 行，点击 self._execute(Command.CLICK_ELEMENT) 文件 "C:\Python27\lib\site-packages\selenium\webdriver\remote\webelement.py", 第 453 行，在 _execute return self._parent.execute(command, params) 文件 "C:\Python27\lib\site-packages\selenium\webdriver\remote\webdriver.py", 第 201 行，在执行中 self.error_handler.check_response(response) 文件 "C:\Python27\lib\site-packages\selenium\webdriver\remote\errorhandler.py", 第 181 行，在 check_response 中 raise exception_class(message, screen, stacktrace) selenium.common.exceptions.ElementNotVisibleException: 消息： {"errorMessage":"元素当前不可见，可能不可见 操纵","请求":{"headers":{"Accept":"application/json","Accept-Encoding":"identity","Connection":"close","Content-Length":"81" ,"Content-Type":"application/json;charset=UTF-8","Host":"127.0.0.1:63160","User-Agent":"Python-urllib/2.7"},"httpVersion": "1.1","方法":"POST","post":"{\"sessionId\": \"5d3cfdc0-5d3b-11e5-b784-67706273a0bb\", \"id\": \":wdc:1442494581220\"}","url":"/click","urlParsed":{"anchor":"","query":"","file":"click","directory" :"/","path":"/click","re​​lative":"/click","port":"","host":"","password":"","user":"" ,"userInfo":"","authority":"","protocol":"","source":"/click","queryKey":{},"chunks":["click"]}," urlOriginal":"/session/5d3cfdc0-5d3b-11e5-b784-67706273a0bb/element/%3Awdc%3A1442494581220/click"}} 屏幕截图：可通过屏幕获取

有什么问题？

Answer 1

既然，你正在做以下 -

driver.find_elements_by_class_name("next_last")[0].click()

如果您查看源代码，则有多个具有此类名称的元素，第一个被禁用，因为这是上一个按钮，您在第一页。
