选择第二个<li>选项列表中的元素 Selenium

Question

I'm having a doozy running into different errors. The goal is set a picklist option so that a report page with various stats updates. The picklist is to choose months and years and whenever I want this report it's for the previous month so the option i always want is the previous months which ends up being li#2.

So I have the following

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

If i do something like

ReportPeriodInput.click()

I get the following error

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

If I alter how I do it and add get_attribute('innerHTML)

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

I get the following error

AttributeError: 'str' object has no attribute 'click'

What is the correct way to select this element and have it be the new value in the picklist? See below for the HTML page details

<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>
<table summary="combobox" border="0" style="border-width:0;border-collapse:collapse;width:250px">
    <tr class="rcbReadOnly">

And an image of what that looks like:

Answer 1

I'm not too familiar with python but knowing how it works in other languages you should be able to just get a list of elements using .find_elements_by_css_selector() and then clicking on the second element in the list.

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

Of course, you would need to click on the dropdown menu first in order to click on the second li element in the menu. Hope this helps.

Answer 2

Based on others help the easiest (may not be the best) way to do it was to make sure to click on the picklist field itself, then I was able to have it find element[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

Let us analyze first what happened with your code trials.

• You have identified an WebElement and tried to invoke click() as follows :

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

  But this <li> is an look alike of option within the DropDown . Hence you see :

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

• Next you have extracted the innerHTML of the above WebElement which returns a String and tried to invoke click() on it. click() method is defined for WebElement . As String Class objects have no click() method associated you see the error :

   AttributeError: 'str' object has no attribute 'click'

Solution :

To click on the DropDown and select the option (11)November - 2017 you have to :

• Identify the Dropdown WebElement and click on it as follows :

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

• Next you need to click the intended option from the Dropdown as follows :

   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()

Answer 4

As I can see that you have given class to each li , the best way to select the second li or say a particular child is using css_selector method.

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

The above code will select (11)November - 2017
