消息:元素<选项>尝试通过 Selenium 单击下拉菜单中的选项时无法滚动到视图中 [英] Message: Element &lt;option&gt; could not be scrolled into view while trying to click on an option within a dropdown menu through Selenium

问题描述

我正在尝试选择一个下拉菜单并选择一个选项.我正在使用最新版本的 Selenium、最新版本的 Firefox、最新版本的 geckodriver 和最新版本的 Python.

I am trying to select a drop down menu and choose an option. I am using the latest version of Selenium, the latest version of Firefox, the latest version of geckodriver, and the latest version of Python.

这是我的问题:当我尝试选择一个选项时，出现以下错误:

Here is my issue: When I try to choose an option, it gives me the following error:

selenium.common.exceptions.ElementNotInteractableException: Message: Element <option> could not be scrolled into view.

我尝试了各种方法来解决这个问题，但似乎都没有奏效.以下是我尝试过的一些方法.

I have tried various ways to circumnavigate this issue, but none seem to work. Here are some of the approaches I tried.

mySelectElement = browser.find_element_by_id('providerTypeDropDown')
dropDownMenu = Select(mySelectElement)
dropDownMenu.select_by_visible_text('Professional')

mySelectElement = browser.find_element_by_id('providerTypeDropDown')
dropDown = Select(mySelectElement)
for option in dropDown.options:
    message = option.get_attribute('innerText')
    print(message)
    if message == 'Professional':
        print("Exists")
        dropDown.select_by_visible_text(message) 
        break

element = browser.find_element_by_id('providerTypeDropDown')
browser.execute_script("var select = arguments[0]; for(var i = 0; i < select.options.length; i++){ if(select.options[i].text == arguments[1]){ select.options[i].selected = true; } }", element, "Professional")

HTML 代码遵循通常的选择标签和选项标签.任何帮助表示赞赏.HTML 代码包含在下面.

The HTML code follows the usual select tags and option tags. Any help is appreciated. The HTML code is included below.

<select data-av-chosen="providerTypes" id="providerTypeDropDown" data-placeholder="Please Select a Provider Type" name="providerTypeDropDown"
class="chzn-select input-full ng-pristine chzn-done ng-invalid ng-invalid-provider-type" data-ng-options="providerType.value for providerType in request.models.providerTypes"
data-ng-model="request.models.providerType" data-av-validator-field="providerType" data-disable-search-threshold="5" style="display; none;">
    <option value="" class="">Please Select a Provider Type</option>
    <option value="0">Professional</option>
    <option value="1">Institutional</option>
</select> 

打印语句用于测试/代码跟踪.

The print statements are there for testing/code tracing purposed.

推荐答案

此错误信息...

selenium.common.exceptions.ElementNotInteractableException: Message: Element <option> could not be scrolled into view.

...表示您的程序试图与之交互的 项无法滚动到视图中.

...implies that the <option> item which your program was trying to interact with could not be scrolled into view.

所需元素的 HTML 会给我们一些错误背后的想法.然而，似乎所需的元素不是 clickable/视口.要解决此问题，您必须将 WebDriverWait 引入 元素以使其可点击，您可以使用以下解决方案:

The HTML of the desired element would have given us some idea behind the error. However it seems the desired element was not clickable / within the Viewport. To address the issue you have to induce WebDriverWait for the element to be clickable and you can use the following solution:

mySelectElement = browser.find_element_by_id('providerTypeDropDown')
dropDownMenu = Select(mySelectElement)
WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, "//select[@id='providerTypeDropDown']//options[contains(.,'Professional')]")))
dropDownMenu.select_by_visible_text('Professional')

注意:您必须添加以下导入:

Note : You have to add the following imports :

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.select import Select
