推荐答案

我正在使用带有vc的jQuery的Dynamic DropDownList

Hi I am using mvc with jQuery for Dynamic DropDownList

/******************************** COUNTRY DROPDOWN LIST ***************************************/
@Html.DropDownList("CountryId", ViewBag.CountryId as SelectList,"Please Select", new { onchange = "javascript:OnCountryChange(this.value);" })
@Html.DropDownList("CityId")

/*************************** WHEN COUNTRY CHANGED ********************************************/
function OnCountryChange(value) 
{

.ajax( { 类型:" ， 数据类型:" ， 网址:" ， 数据:" + 值 ， ContentType:" ， // 异步:false， 成功:功能(数据) { // 警报(在安全地点内")； // 调试器； var ddl =

.ajax( { type: "POST", datatype: "json", url: "/Location/GetCityListByCountryId", data: "cid=" + value, ContentType: "application/Json", //async: false, success: function (data) { //alert('inside the secure place'); //debugger; var ddl =

(" )； ddl.empty(); 如果(数据长度> 0 ) {

("#CityId"); ddl.empty(); if (data.length > 0) {
