selenium获取iframe下的dropdown封装的动态下拉框元素

以下是使用Selenium获取iframe下的dropdown封装的动态下拉框元素的示例代码：

from selenium.webdriver.support.ui import Select

class DynamicDropdown:
    def __init__(self, driver, iframe_id, dropdown_id):
        self.driver = driver
        self.iframe_id = iframe_id
        self.dropdown_id = dropdown_id

    def select_option_by_visible_text(self, option_text):
        self.driver.switch_to.frame(self.iframe_id)
        dropdown = Select(self.driver.find_element_by_id(self.dropdown_id))
        dropdown.select_by_visible_text(option_text)
        self.driver.switch_to.default_content()

使用方法：

from selenium import webdriver

driver = webdriver.Chrome()
driver.get("https://example.com")

# switch to iframe
iframe_id = "frameId"
driver.switch_to.frame(iframe_id)

# initialize dynamic dropdown object
dropdown_id = "dropdownId"
dynamic_dropdown = DynamicDropdown(driver, iframe_id, dropdown_id)

# select option by visible text
option_text = "Option 1"
dynamic_dropdown.select_option_by_visible_text(option_text)

# switch back to default content
driver.switch_to.default_content()
