python之splinter select(value) 返回属性错误

尝试从此 url 获取所有 (5) 个表。

我可以用 type(value) 填充各个页面的下拉框，但这不会刷新页面。使用 nextPage 按钮单步浏览页面后会失败，因为该对象不再附加到 DOM(而且我不知道如何在 splinter 中绕过它)。

尝试填充下拉菜单然后选择它。这将返回此错误:

追溯(最近的调用最后):

File "<stdin>", line 69, in <module> 
File "/usr/local/lib/python2.6/dist-packages/splinter/driver/webdriver/__init__.py", line 334, in select 
 self.find_by_xpath('//select[@name="%s"]/option[@value="%s"]' % (self["name"], value))._element.click() 
File "/usr/local/lib/python2.6/dist-packages/splinter/element_list.py", line 73, in __getattr__ 
  self.__class__.__name__, name)) 
AttributeError: 'ElementList' object has no attribute '_element' 

我使用了下面的代码。非常感谢任何帮助!

    maxpagev = max(pagevals)

    '''

            print ns, sel.value, sel.text 
            sel.type(sel.value) 
            sleep(2) 
 
    moldata = list() 
    for page in range(len(pagevals)): 
 
        content = browser.html 
        parsed = parse(StringIO(content)) 
        doc = parsed.getroot() 
        tables = doc.findall('.//table') 
        schdls = tables[91] 
 
        #Get all rows from that table 
        rows = schdls.findall('.//tr') 
        hdr, data = parse_schdls_data(schdls) 
        #print page, data 
        moldata.append(data) 
 
        while browser.is_element_not_present_by_tag('select', wait_time = 2): 
            pass 
 
        inputs = browser.find_by_tag('input') 
        selects = browser.find_by_tag('select') 
 
        #inputs[35].click() 
 
        #selects[0].type(str(page + 1)) 
        selects[0].select(selects[0].value) 

请您参考如下方法:

因为select元素没有名字，所以举个例子:

browser.find_by_xpath('//select[@id="MRBgvPortScheduleInformation_edlPager"]/option[@value="2"]')._element.click()
