根据提供的HTML:

<select id="fruits01" class="select" name="fruits">
  <option value="0">Choose your fruits:</option>
  <option value="1">Banana</option>
  <option value="2">Mango</option>
</select>

要从html-select菜单中选择<option>元素，必须使用select类。此外，当你必须与下拉菜单交互时，你必须为element_to_be_clickable()诱导WebDriverWait。

要从下拉菜单中选择<选项>，文本为Mango，你可以使用以下定位器策略之一:

Using ID attribute and select_by_visible_text() method: 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 from selenium.webdriver.support.ui import Select select = Select(WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.ID, "fruits01")))) select.select_by_visible_text("Mango") Using CSS-SELECTOR and select_by_value() method: select = Select(WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "select.select[name='fruits']")))) select.select_by_value("2") Using XPATH and select_by_index() method: select = Select(WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "//select[@class='select' and @name='fruits']")))) select.select_by_index(2)

除非您的单击触发了某种ajax调用来填充列表，否则实际上不需要执行单击。

只需找到元素，然后枚举选项，选择您想要的选项。

这里有一个例子:

from selenium import webdriver
b = webdriver.Firefox()
b.find_element_by_xpath("//select[@name='element_name']/option[text()='option_text']").click()

我用它进行所有的点击和选择，它总是有效的。对于下拉项，只需确保xpath是您想要选择的实际值。

var = WebDriverWait(driver, explicit_wait_seconds).until(
        EC.element_to_be_clickable((By.XPATH, self)))
    # added the click here.
    ActionChains(driver).move_to_element(var).click()
    perform_actions()

actions.perform()
 # Reset was required to clear it. Might be patched now.
actions.reset_actions()
for device in actions.w3c_actions.devices:
    device.clear_actions()

Selenium提供了一个方便的Select类来使用Select ->选项结构:

from selenium import webdriver
from selenium.webdriver.support.ui import Select

driver = webdriver.Firefox()
driver.get('url')

select = Select(driver.find_element_by_id('fruits01'))

# select by visible text
select.select_by_visible_text('Banana')

# select by value 
select.select_by_value('1')

使用Selenium的Python WebDriver的正确方法是什么?

from selenium.webdriver.support.ui import Select
driver = webdriver.Ie(".\\IEDriverServer.exe")
driver.get("https://test.com")
select = Select(driver.find_element_by_xpath("""//input[@name='n_name']"""))
select.select_by_index(2)

它会正常工作的

使用selenium.webdriver.support.ui.的最佳方式是使用下拉选择选择要工作的类，但有时由于设计问题或HTML的其他问题，它不能像预期的那样工作。

在这种情况下，您也可以使用execute_script()作为替代解决方案，如下所示

option_visible_text = "Banana"
select = driver.find_element_by_id("fruits01")

#now use this to select option from dropdown by visible text 
driver.execute_script("var select = arguments[0]; for(var i = 0; i < select.options.length; i++){ if(select.options[i].text == arguments[1]){ select.options[i].selected = true; } }", select, option_visible_text);
