为什么我不能通过 selenium 选择菜单？

Question

<div class="fancy-select" data-file=""><label>Choose a file</label>
<select>
  <option value="admin_20210519182831.log">SaveFiles\Logs\admin_20210519182831.log</option>
  <option value="admin_20210519183038.log">SaveFiles\Logs\admin_20210519183038.log</option>
  <option value="chat_20210519182831.log">SaveFiles\Logs\chat_20210519182831.log</option>
  <option value="chat_20210519183038.log">SaveFiles\Logs\chat_20210519183038.log</option>
</select>

我的代码

get_div = Select(driver.find_element_by_class_name('fancy-select'))
get_div.select_by_value("chat_20210519183038.log")

错误

Traceback (most recent call last):
  File "C:\Users\Up\Desktop\New folder\test02.py", line 36, in <module>
    get_div = Select(driver.find_element_by_class_name('fancy-select'))
  File "C:\Users\Up\AppData\Roaming\Python\Python39\site-packages\selenium\webdriver\support\select.py", line 37, in __init__
    raise UnexpectedTagNameException(
selenium.common.exceptions.UnexpectedTagNameException: Message: Select only works on <select> elements, not on <div>

第 36 行

get_div = Select(driver.find_element_by_class_name('fancy-select'))

我已经被这个错误困扰了很长时间，试图弄清楚并尝试修复它，但它没有通过。请帮助知道帮助的人。

Answer 1

看到你得到的错误UnexpectedTagNameException: Message: Select only works on <select> elements, not on <div>你需要做的就是传递选择标签定位器。

您在 Select 类中定位 div。从 selenium 中选择类只了解选择标签。所以改变你的定位器可能对你有用。

XPATH：

//lable[text()='Choose a file']/following-sibling::select

代码：

get_div = Select(driver.find_element_by_xpath("//lable[text()='Choose a file']/following-sibling::select"))
get_div.select_by_value("chat_20210519183038.log")

Answer 2

你可以尝试给选择标签一个id fancy-sel：

select = Select(driver.find_element_by_id('fancy-sel'))

# select by visible text
select.select_by_visible_text('SaveFiles\Logs\chat_20210519183038.log')

# select by value 
select.select_by_value('chat_20210519183038.log')
