如何从非选择标签的下拉菜单中选择一个选项？

Question

我正在尝试从下拉菜单中选择一个值。我尝试了很多在这里找到的解决方案，但是没有用，有时我遇到无法滚动查看的错误。

代码试用：

import time
from selenium import webdriver
from selenium.webdriver.support.wait import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.select import Select
from selenium.webdriver.common.action_chains import ActionChains

browser = webdriver.Chrome()  # Optional argument, if not specified will search path.
browser.get('https://dzairannonces.com/posts/create');
mySelectElement = browser.find_element_by_id('parentId')
dropDownMenu = Select(mySelectElement)

我想从下拉菜单中选择一个值，然后从第二个下拉菜单中选择另一个值，当我们选择第一个时出现

我也尝试过此代码，但不起作用

import unittest
from selenium import webdriver
from selenium.webdriver.support.select import Select
import time


class Drpdowm(unittest.TestCase):

    def setUp(self):
        self.driver = webdriver.Chrome()

    def test_drpdown(self):
        driver = self.driver
        driver.maximize_window()
        driver.get('https://dzairannonces.com/posts/create')
        time.sleep(10) # Let the user actually see something!
        s1=Select(driver.find_element_by_id('parentId'))

        print(s1.options)


        for opt in s1.options:
            s1.select_by_value(' 315 ')

    def tearDown(self):
        self.driver.quit()

Answer 1

正确的代码应为

s1=Select(driver.find_element_by_id('parentId'))
s1.select_by_value('315')

HTML attributes对于多余的空格或换行符非常严格，您需要提供值准确无误

有关专门用于Select Support的Python WebDriver API，请参见<select> tags一章

关于整体测试设计，一个不错的主意是实施Page Object Model Design Pattern，它将使您能够拆分UI和测试逻辑，并使您的测试健壮，可靠并且易于重构。有关更多信息，请参见Page Objects一章。

Answer 2

要选择一个选项，例如从非 <select>标签的下拉菜单中，汽车可以使用以下解决方案：

• 代码块：

  from selenium import webdriver
  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.common.by import By
  from selenium.webdriver.support import expected_conditions as EC
  
  options = webdriver.ChromeOptions()
  options.add_argument('start-maximized')
  driver = webdriver.Chrome(chrome_options=options, executable_path=r'C:\WebDrivers\chromedriver.exe')
  driver.get('https://dzairannonces.com/posts/create')
  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "span.select2-selection__rendered#select2-parentId-container"))).click()
  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//span[@class='select2-results']/ul//li[@class='select2-results__option' and contains(., 'Automobiles')]"))).click()
