可以使用<code>first_selected_option</code>返回当前选定的 <pre><code>selected = mySelect.first_selected_option print(selected.text) </code></pre> 示例： <pre><code>from selenium import webdriver from selenium.webdriver.common.by import By from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.support import expected_conditions as EC from selenium.webdriver.support.ui import Select url = 'http://www.debentures.com.br/exploreosnd/consultaadados/sndemumclique/' driver = webdriver.Chrome() driver.get(url) options = WebDriverWait(driver,10).until(EC.presence_of_all_elements_located((By.CSS_SELECTOR, '[name="ctl00$ddlEmi"] option'))) importer = 3 mySelect = Select(driver.find_element_by_css_selector('[name="ctl00$ddlEmi"]')) mySelect.select_by_index(importer) selected = mySelect.first_selected_option print(selected.text) </code></pre> <hr/> 您可以使用attribute=value css选择器获取option元素，然后从中获取.text <pre><code>label = driver.find_element_by_css_selector('[value="C704"]').text </code></pre> <hr/> 但是你可以避免索引和文本选择 <pre><code>select.select_by_visible_text('Viet Nam') </code></pre> <hr/> 或者抓住所有的选择 <pre><code>options = driver.find_elements_by_css_selector('[name="ctl00$c$cboExporter"] option') </code></pre> 然后索引到其中并使用.text返回关联的值 示例： <pre><code>from selenium import webdriver from selenium.webdriver.common.by import By from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.support import expected_conditions as EC url = 'http://www.debentures.com.br/exploreosnd/consultaadados/sndemumclique/' driver = webdriver.Chrome() driver.get(url) options = WebDriverWait(driver,10).until(EC.presence_of_all_elements_located((By.CSS_SELECTOR, '[name="ctl00$ddlEmi"] option'))) options[5].click() print(options[5].text) </code></pre> <hr/> 如果你想尝试一个循环 <pre><code>options = driver.find_elements_by_css_selector('[name="ctl00$c$cboExporter"] option') for option in options: option.click() print(option.text) </code></pre> 下面是一个循环示例 <pre><code>from selenium import webdriver from selenium.webdriver.common.by import By from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.support import expected_conditions as EC url = 'http://www.debentures.com.br/exploreosnd/consultaadados/sndemumclique/' driver = webdriver.Chrome() driver.get(url) options = WebDriverWait(driver,10).until(EC.presence_of_all_elements_located((By.CSS_SELECTOR, '[name="ctl00$ddlEmi"] option'))) for option in options[1:]: option.click() print(option.text) </code></pre>
