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（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

正如您所看到的，代码返回纯HTML，我正在使用HTMLParser库进行解析。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

检查出来，这是我在知道Select Module做了什么之前的做法

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

像这样输出

Answer 2

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'))

打印

(u'--SELECT COUNTRY--', u'-1')
(u'New Zealand', u'459')
(u'USA', u'100')
(u'UK', u'300')

我学到了here。另请参阅the docs。

Answer 3

更简单的版本：

dropdown_menu = Select(driver.find_element_by_name(<NAME>))
for option in dropdown_menu.options:
        print option.text

Answer 4

稍微改进的答案。在 Selenium 和 Python 中，如果要获取所有属性值，请使用以下列表推导式：

options = [x.get_attribute("value") for x in driver.find_element_by_id("yourlocator").find_elements_by_tag_name("option")]
print(options)

对 .text 的简单调用不适用于列表。使用：

options = [x.get_attribute("innerText") for x in driver.find_element_by_id("yourlocator").find_elements_by_tag_name("option")]
print(options)

列出使用Selenium和Python选择选项值
