Listing select option values with Selenium and Python
提问by Leonardo Cardoso
I have the following HTML code
我有以下 HTML 代码
<select name="countries" class_id="countries">
<option value="-1">--SELECT COUNTRY--</option>
<option value="459">New Zealand</option>
<option value="100">USA</option>
<option value="300">UK</option>
</select>
I am trying to get a list of the option values (like 459, 100, etc, not the text) using Selenium.
我正在尝试使用 Selenium 获取选项值列表（如 459、100 等，而不是文本）。
At the moment I have the following Python code
目前我有以下 Python 代码
from selenium import webdriver
def country_values(website_url):
browser = webdriver.Firefox()
browser.get(website_url)
html_code=browser.find_elements_by_xpath("//select[@name='countries']")[0].get_attribute("innerHTML")
return html_code
As you can see the code returns pure HTML, which I am parsing with HTMLParser library. Is there any way to get the option values just using Selenium? In other words, without having to parse the result from Selenium?
如您所见，代码返回纯 HTML，我正在使用 HTMLParser 库对其进行解析。有没有办法只使用 Selenium 来获取选项值？换句话说，无需解析来自 Selenium 的结果？

check it out, here is how i did it before i knew what the Select Module did
检查一下，这是我在知道选择模块做了什么之前我是怎么做的
from selenium import webdriver
browser = webdriver.Firefox()
#code to get you to the page
select_box = browser.find_element_by_name("countries")
# if your select_box has a name.. why use xpath?.....
# this step could use either xpath or name, but name is sooo much easier.
options = [x for x in select_box.find_elements_by_tag_name("option")]
# this part is cool, because it searches the elements contained inside of select_box
# and then adds them to the list options if they have the tag name "options"
for element in options:
print element.get_attribute("value")
# or append to list or whatever you want here
outputs like this
像这样的输出
-1
459
100
300

import selenium.webdriver as webdriver
import selenium.webdriver.support.ui as UI
import contextlib
with contextlib.closing(webdriver.Firefox()) as driver:
driver.get(url)
select = UI.Select(driver.find_element_by_xpath('//select[@name="countries"]'))
for option in select.options:
print(option.text, option.get_attribute('value'))
prints
印刷
(u'--SELECT COUNTRY--', u'-1')
(u'New Zealand', u'459')
(u'USA', u'100')
(u'UK', u'300')

Simpler version:
更简单的版本：
dropdown_menu = Select(driver.find_element_by_name(<NAME>))
for option in dropdown_menu.options:
print option.text
