python - 使用 Selenium 和 Python 列出选择选项值

Question

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>

我正在尝试使用 Selenium 获取选项值列表(例如 459、100 等，而不是文本)。

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

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 Selenium 的结果？

Answer 1

检查一下，这是我在知道选择模块做了什么之前是怎么做的

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

这样的输出

-1
459
100
300
