由于 <span>（Python - Selenium），无法从动态下拉菜单中抓取输入

Question

这是一个有点讨论的问题，但是我在其他帖子中没有找到解决方案。

我在 Python 上使用 Selenium 为这个网站创建一个提交包裹的自动化： https://www.mondospedizioni.com

对于 select 国家和城市，我需要在文本字段中添加输入。文本字段实际上是一个搜索字段，在添加键后会打开一个下拉菜单。

我无法select选项并关闭下拉菜单，因此填写“国家/地区”/“城市”字段并向前移动。

我指的div(国家):

<span class="select2-selection__rendered" id="select2-nazione_mittente-container" title="Selezionare Nazione di ritiro">Selezionare Nazione di ritiro</span>

城市:

<span class="select2-selection__placeholder">Inserire il CAP e selezionare la località</span>

使用 Select，但由于标签我收到错误：

Select only works on <select> elements, not on <span>.

我在 from Anzel 中找到了另一个建议，但即使这个建议也不适合我。

当我尝试输入发件人的城市时，我的代码卡住了，当代码调用收件人国家/地区的输入字段时出现错误。我的代码：

编辑为了澄清这个问题，我现在添加了两个打印屏幕，它们专注于我无法管理的元素 - 发件人的位置。

它比我习惯的更先进（而且我对 Selenium 还很陌生）。

Answer 1

#select2-nazione_mittente-container

只需点击上面的元素

.select2-search__field

将密钥发送到上述元素

//li[@class='select2-results__option' and contains(@id,'Italia')]

然后继续单击具有该值的 li 标签。

这是处理任何非 Select 下拉元素的方法。

Answer 2

事实证明，实际上我需要定位并且只有在下拉菜单中只有一个选项时才有效。

我想到了这个解决方案并且它有效，因为我能够完成表单的自动化：

#Sender's City
cityFrom = driver.find_element(By.XPATH, '//*[@id="select2-loc_cap_mittente-container"]').click()
select_cityFrom = driver.find_element(By.XPATH, '/html/body/span/span/span[1]/input').send_keys('Partanna')
time.sleep(1)
confirm_cityFrom = driver.find_element(By.XPATH, '//*[@id="select2-loc_cap_mittente-results"]/li/div').click()

由于 <span>（Python - Selenium），无法从动态下拉菜单中抓取输入

Cannot scrape input from dynamic dropdown menu due to <span> (Python - Selenium)
