如何查看下拉菜单中有多少选项？

// 使用JavaScript
var selectElement = document.getElementById("select-element-id");
var optionsCount = selectElement.options.length;
console.log("下拉菜单中有 " + optionsCount + " 个选项");

// 使用jQuery
var optionsCount = $("#select-element-id option").length;
console.log("下拉菜单中有 " + optionsCount + " 个选项");

/* 使用CSS */
select-element-id {
  display: block;
}

from selenium import webdriver

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

select_element = driver.find_element_by_id("select-element-id")
options_count = len(select_element.find_elements_by_tag_name("option"))
print("下拉菜单中有 " + str(options_count) + " 个选项")
