我一直在尋找有關(guān)如何在html.dropdownlist上添加HTML類標(biāo)簽的答案。這是代碼<%: Html.DropDownList("PackageId", new SelectList(ViewData["Packages"] as IEnumerable, "PackageId", "Name", Model.PackageId))%>我想在select元素下添加選項(xiàng)的類，以便可以使用此鏈接的select：<select id="category">  <option value="1">One</option>  <option value="2">Two</option></select><select id="package">  <option value="1" class="1">One - package1</option>  <option value="2" class="1">One - package2</option>  <option value="3" class="2">Two - package1</option>  <option value="4" class="2">Two - package2</option></select>$("#series").chained("#mark");
