选择第二个 选项列表中的元素Selenium

Question

我遇到了不同的错误。目标是设置一个选项列表选项，以便具有各种统计信息更新的报告页面。选项列表是选择月份和年份，每当我想要这个报告时，它就是前一个月所以我一直想要的选项是前几个月最终是li＃2。

所以我有以下内容

ReportPeriodInput = DriverTransactionSummary.find_element_by_xpath('//*[@id="dnn_ctr1001_VolumeByMonthCS_rcbPeriod_DropDown"]/div/ul/li[2]')

如果我做的事情

ReportPeriodInput.click()

我收到以下错误

selenium.common.exceptions.ElementNotVisibleException: Message: element not visible

如果我改变我的方式并添加get_attribute（'innerHTML）

ReportPeriodInput = DriverTransactionSummary.find_element_by_xpath('//*[@id="dnn_ctr1001_VolumeByMonthCS_rcbPeriod_DropDown"]/div/ul/li[2]').get_attribute('innerHTML')
ReportPeriodInput.click()

我收到以下错误

AttributeError：'str'对象没有属性'click'

选择此元素并将其作为选项列表中的新值的正确方法是什么？请参阅下面的HTML页面详细信息

<div id="dnn_ctr1001_VolumeByMonthCS_rcbPeriod" class="RadComboBox RadComboBox_Windows7 RadComboBoxWithLabel" style="white-space:normal;">

Answer 1

我对python不是很熟悉，但知道它在其他语言中是如何工作的，你应该能够使用.find_elements_by_css_selector()获取元素列表，然后单击列表中的第二个元素。

options = DriverTransactionSummary.find_elements_by_css_selector(".rcbItem")
options[1].click();

当然，您需要先单击下拉菜单才能单击菜单中的第二个li元素。希望这可以帮助。

Answer 2

基于其他人帮助最简单（可能不是最好）的方法是确保单击选项列表字段本身，然后我能够找到元素[2]。

ReportPeriodClick = DriverTransactionSummary.find_element_by_xpath('//*[@id="dnn_ctr1001_VolumeByMonthCS_rcbPeriod_Input"]').click()
ReportPeriodClick2 = DriverTransactionSummary.find_element_by_xpath('//*[@id="dnn_ctr1001_VolumeByMonthCS_rcbPeriod_DropDown"]/div/ul/li[2]').click()

Answer 3

让我们首先分析您的代码试验发生了什么。

• 你已经确定了一个WebElement并试图调用click()如下：

  ReportPeriodInput = DriverTransactionSummary.find_element_by_xpath('//*[@id="dnn_ctr1001_VolumeByMonthCS_rcbPeriod_DropDown"]/div/ul/li[2]')
  ReportPeriodInput.click()

  但这个<li>看起来像option中的DropDown。因此你看到： selenium.common.exceptions.ElementNotVisibleException: Message: element not visible
• 接下来你提取了上面的innerHTML的WebElement，它返回一个String并试图在它上面调用click()。 click()方法是为WebElement定义的。由于String类对象没有关联的click()方法，因此您会看到错误： AttributeError: 'str' object has no attribute 'click'

方案：

要点击DropDown并选择(11)November - 2017选项，你必须：

• 确定Dropdown WebElement并点击它如下：

  ReportPeriodInput = DriverTransactionSummary.find_element_by_xpath("//div[@class='RadComboBoxDropDown RadComboBoxDropDown_Windows7' and contains(@id,'VolumeByMonthCS_rcbPeriod_DropDown')]")
  ReportPeriodInput.click()

• 接下来，您需要点击option中的预期Dropdown，如下所示：

  ReportPeriodInputOption = DriverTransactionSummary.find_element_by_xpath("//div[@class='RadComboBoxDropDown RadComboBoxDropDown_Windows7' and contains(@id,'VolumeByMonthCS_rcbPeriod_DropDown')]/div/ul/li[@class='rcbItem' and contains(.,'November - 2017')]")
  ReportPeriodInputOption.click()
