源码如图：   直接使用Select类进行选择，selector(driver.find_element_by_id("Agency")) 会提示如下信息 raise exception_class(message, screen, stacktrace) selenium.common.exceptions.ElementNotInteractableException: Message: element not interactable: Element is not currently visible and may not be manipulated

# 下拉选择框随机选择
def selector(self,element):
    ele = Select(element)
    count_options = len(ele.options) - 1
    ele.select_by_index(random.randint(0, count_options))

  display元素没有定义，直接通过js修改是无效的。必须通过修改元素的style样式的display属性才成功。  

agency_ele = driver.find_element_by_id("Agency")
js = """ele = document.getElementById("Agency");
ele.style.display='block';
"""
driver.execute_script(js)
selector(agency_ele)
