Python / Selenium 如何与隐藏的 Select 元素交互

Question

这是我需要 select 特定选项的元素的 HTML 代码

<div class="ui-dropdownlistcontrol">
<select id="ApplicantTitle" name="ApplicantTitle" class="select2-hidden-accessible" data-select2-id="ApplicantTitle" tabindex="-1" aria-hidden="true">
    <option value="0" selected="" data-select2-id="2">&nbsp;</option>
    <option value="1" data-select2-id="6">Mr</option>
    <option value="2" data-select2-id="7">Mrs</option>
    <option value="3" data-select2-id="8">Miss</option>
    <option value="4" data-select2-id="9">Ms</option>
    <option value="5" data-select2-id="10">Dr</option>
    <option value="6" data-select2-id="11">Prof</option>
    <option value="7" data-select2-id="12">Hon</option>
    <option value="8" data-select2-id="13">Sir</option>
    <option value="9" data-select2-id="14">Lord</option>
</select>
<span class="select2 select2-container select2-container--default select2-container--below" dir="ltr" data-select2-id="1" style="width: 100%;">
    <span class="selection">
        <span class="select2-selection select2-selection--single" role="combobox" aria-haspopup="true" aria-expanded="false" tabindex="-1" aria-disabled="false" aria-labelledby="select2-ApplicantTitle-container">
            <span class="select2-selection__rendered" id="select2-ApplicantTitle-container" role="textbox" aria-readonly="true">&nbsp;</span>
            <span class="select2-selection__arrow" role="presentation">
                <b role="presentation"></b>
            </span>
        </span>
    </span>
    <span class="dropdown-wrapper" aria-hidden="true"></span>
</span>
<span class="select2 select2-container select2-container--default" dir="ltr" data-select2-id="1" style="width: 100%;">
    <span class="selection">
        <span class="select2-selection select2-selection--single" role="combobox" aria-haspopup="true" aria-expanded="false" tabindex="0" aria-disabled="false" aria-labelledby="select2-ApplicantTitle-container">
            <span class="select2-selection__rendered" id="select2-ApplicantTitle-container" role="textbox" aria-readonly="true">&nbsp;</span>
            <span class="select2-selection__arrow" role="presentation">
                <b role="presentation"></b>
            </span>
        </span>
    </span>
    <span class="dropdown-wrapper" aria-hidden="true"></span>
</span>

Select 元素被隐藏，我不能简单地这样做.....find_elements_by_xpath('./following::select//option[text()="Mr"]')[0].click()

而如果你会 select Mr那么里面的span元素  将更改为所选选项

有人知道如何与隐藏的select元素交互吗？

或任何建议将不胜感激

编辑1：

我可以用这个 id select2-ApplicantTitle-container按下元素，然后下拉菜单会出现，但是从这个打开的列表到 select 的方法是什么？

Answer 1

试试下面的代码::

element = WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, "//select[@name='ApplicantTitle']")))

driver.execute_script("arguments[0].scrollIntoView();", element)  

select = Select(element)
select.select_by_visible_text('Mr')

注意：将以下内容添加到您的解决方案中

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

您可以通过多种方式处理下拉菜单：

1. select_by_index（索引）
2. select_by_value(值)
3. select_by_visible_text（文本）

** 解决方案 2：**

driver.get('https://www.santanderforintermediaries.co.uk/calculators-and-forms/affordability/')
wait = WebDriverWait(driver, 10)
element= wait.until(EC.element_to_be_clickable((By.XPATH, "//span[@id='ddlMethodRepaymentSelectBoxIt']")))
element.click()

element1= wait.until(EC.element_to_be_clickable((By.XPATH, "//ul[@id='ddlMethodRepaymentSelectBoxItOptions']//li[4]/a")))
element1.click()

解决方案3：

driver.get("https://www.santanderforintermediaries.co.uk/calculators-and-forms/affordability/")
driver.implicitly_wait(10)

element1 = WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.ID, "ddlMethodRepaymentSelectBoxIt")))
element1.click()

elements =  WebDriverWait(driver, 30).until(
            EC.visibility_of_all_elements_located((By.XPATH, "//ul[@id='ddlMethodRepaymentSelectBoxItOptions']//li[*]")))


expected_value = "Capital and interest"

for element in elements:
    if element.text == expected_value:
        element.click()
        break

Answer 2

您可以先使用下面的 CSS 再单击 select 项目的select列表。

listEle = driver.find_element_by_css_selector("select#ApplicantTitle")
listEle.click()
#Then you can select the option 
listEle.find_element_by_xpath("./option[.='Mr']").click()

Answer 3

UI 似乎是一个下拉菜单，但并不相同。 If there is a Select tag in HTML and not wrapped in some other tag then it can be selected using Selenium Select class.

在您的参考站点中，您需要模拟相同的单击操作，以便 select 下拉列表中的值。

使用以下代码：

driver.get("https://www.santanderforintermediaries.co.uk/calculators-and-forms/affordability/")
driver.implicitly_wait(10)
# click on dropdown
driver.find_element_by_id("ddlMethodRepaymentSelectBoxIt").click()

#get all dropdown element
elements = driver.find_elements_by_css_selector("#ddlMethodRepaymentSelectBoxItOptions>li")

expected_value = "Part and part - sale of mortgaged property"

# loop through all all element and and check whether element has the expected value to select if yes the select and break out the loop
for element in elements:
    if element.text == expected_value:
        element.click()
        break
