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

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

如果我做的话

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;">
<label for="dnn_ctr1001_VolumeByMonthCS_rcbPeriod_Input" class="rcbLabel">Period:</label>

Answer 1

我对python不是很熟悉，但是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，您需要先点击下拉菜单才能点击菜单中的第二个li元素。希望这会有所帮助。

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

让我们先分析您的代码试验发生了什么。

您已识别出WebElement并尝试按以下方式调用click()：
```
ReportPeriodInput = DriverTransactionSummary.find_element_by_xpath('//*[@id="dnn_ctr1001_VolumeByMonthCS_rcbPeriod_DropDown"]/div/ul/li[2]')
ReportPeriodInput.click()
```
但是<li> option与DropDown中的selenium.common.exceptions.ElementNotVisibleException: Message: element not visible相似。因此，您看到：
```
innerHTML
```
接下来，您已提取上述WebElement的{{1}}，其中String会返回click()，并尝试在其上调用click()。 WebElement定义了String方法。由于click()类对象没有关联AttributeError: 'str' object has no attribute 'click'方法，因此您会看到错误：
```
DropDown
```

解决方案：

点击 (11)November - 2017 ，然后选择 Dropdown 选项：

确定 WebElement ReportPeriodInput = DriverTransactionSummary.find_element_by_xpath("//div[@class='RadComboBoxDropDown RadComboBoxDropDown_Windows7' and contains(@id,'VolumeByMonthCS_rcbPeriod_DropDown')]") ReportPeriodInput.click()并按如下所示点击它：
```
option
```
接下来，您需要点击 Dropdown 中的预定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()，如下所示：
```
 while (.10 <= diff < .25)
```

Answer 4

正如我所见，您已经为每个 li 授课，这是选择第二个 li 或说某个特定孩子正在使用 css_selector < / strong>方法。

driver.find_element_by_css_selector("ul .rcbItem:nth-child(2)").click()

上面的代码将选择(11)November - 2017

在选择列表Selenium中选择2nd <li>元素
