在 Python 中使用 Selenium 执行 JavaScript 后存储结果

我正在尝试使用硒在锚标签内执行javascript函数，并试图将该结果存储在某个地方

网页代码：

<td>
<td>
  <ul class="compare">
    <li class="floatRight dividLineLeft category_page_navigation">
       <div class="page_navigation">
           <span id="ctl00_ctl00_ContentPlaceHolder1_ItemListPlaceHolder_pager1">
               <a style="width: 22px; height: 22px;" disabled="disabled">
               <a style="width: 22px; height: 22px;" href="javascript:__doPostBack('ctl00$ctl00$ContentPlaceHolder1$ItemListPlaceHolder$pager1$ctl00$ctl01','')">
           </span>
       </div>
    </li>
  </ul>
</td>

下面是我的代码

from selenium import webdriver
driver = webdriver.Chrome('/usr/bin/chromedriver')
driver.get("http://www.e3050.com/Items.aspx?cat=SON");
anchor_tags = driver.find_element_by_xpath("//div[@class='page_navigation']/span[@id='ctl00_ctl00_ContentPlaceHolder1_ItemListPlaceHolder_pager1']")
anchor_tags_res = anchor_tags.find_elements_by_tag_name("a")
for anchor_tag in anchor_tags_res:
      href=[]
      href.append(anchor_tag.get_attribute("href"))
      for i in href:
          element = driver.execute_script(i)
          print element

在这里，我能够从锚标签中获取 href，但是当我尝试执行如上所示时，它会显示以下错误。当我使用 click（） 函数时，例如

for anchor_tag in anchor_tags:
      anchor_tag.click()

正常，但我想存储执行的结果，因为在上面的代码中javascript函数只不过是生成分页的

结果：

---------------------------------------------------------------------------
WebDriverException                        Traceback (most recent call last)
/home/local/<ipython console> in <module>()
/usr/lib/python2.7/site-packages/selenium-2.21.3-py2.7.egg/selenium/webdriver/remote/webdriver.pyc in execute_script(self, script, *args)
    383         converted_args = list(args)
    384         return self.execute(Command.EXECUTE_SCRIPT,

    152         if response:
--> 153             self.error_handler.check_response(response)
    154             response['value'] = self._unwrap_value(
    155                 response.get('value', None))

    124                 raise exception_class(response, value)
--> 125             raise exception_class(value)
    126         message = ''
    127         if 'message' in value:
WebDriverException: Message: '{"sessionId":"ed4b6f549a9902254bc49399cddbe79a","status":400,"value":{"message":"No script specified"}}'

那么在硒中执行javascript后如何存储结果

提前感谢...

编辑的代码：

from selenium import webdriver
driver = webdriver.Chrome('/usr/bin/chromedriver')
driver.get("http://www.e3050.com/Items.aspx?cat=SON");
anchor_tags = driver.find_element_by_xpath("//div[@class='page_navigation']/span[@id='ctl00_ctl00_ContentPlaceHolder1_ItemListPlaceHolder_pager1']")
all_options = anchor_tags.find_elements_by_tag_name("a")
hrefs = all_options[1].get_attribute("href")
res = hrefs.encode('utf-8')
element = driver.execute_script('%s'%res)
WebDriverWait(driver, timeout=10).until(lambda x: x.find_element_by_id('ctl00_ctl00_ContentPlaceHolder1_ItemListPlaceHolder_itemslv_ctrl0_Counterlbl'))
print element,"Here should be the result"

并且通过终端从文件运行了此代码，我没有收到任何错误，但结果是没有。实际上我想在javascript执行后保存结果。请让我知道为什么结果是空的......

提前感谢...
