我有三个下拉列表。
$(document).ready(function () {
$("#DropDownList1").change(function () {
$("#Id1").val($(this).val());
$("#Name1").val($("#DropDownList1 option:selected").text());
$('#Div1').load('/Account/Dropdown2/?Id1=' + $("#Id1").val());
});
$("#DropDownList2").change(function () {
$("#routeId").val($(this).val());
$("#routeName").val($("#RouteDropDownList option:selected").text());
$('#Div2').load('/Account/Dropdown3/?Id2=' + $("#routeId").val());
});
$("#DropDownList3").change(function () {
$("#Id3").val($(this).val());
$("#Name3").val($("#DropDownList3 option:selected").text());
});
});
在这个 DropDownList2 和 DropDownList3 是动态添加的。问题是动态添加的下拉菜单没有在页面中注册。所以我没有从 onchange 事件中获取它的选定值。我将这些控件添加为部分视图。控制器。
public ActionResult DropDownList2 (string Id1)
{
List<Emp> empList = new List<Emp>();
Emp em= new Emp ()
{
Id = "1",
Name = "Doac"
};
empList .Add(em);
ViewBag.DropDownList2= new SelectList(empList , "Id", "Name");
return PartialView();
}
