我使用json数据将国家/地区列表,状态列表城市列表绑定到下拉列表。我的要求是基于国家的状态应该改变。根据各州,城市价值观应该改变。假设如果我第一次选择印度各自的州,但是在我更改国家/地区的国家/地区后,新的值不会在状态下拉列表中更新,我会在firebug中获得正确的状态数据。
我的Jsfile:
$(document).ready(function () {
bindData();
BindCountry();
var DropDown1 = $("#ddlCountry");
DropDown1.change(function (e) {
var CountryCode = DropDown1.val();
if (CountryCode >= 1) {
GetStates(CountryCode);
}
});
});
function BindCountry() {
var Dropdown1 = $("#ddlCountry");
$.ajax({
type: "POST",
url: location.pathname + "/GetCountry",
data: "{}",
contentType: "application/json;charset=utf-8",
datatype: "json",
success: function (response) {
var country = response.d;
$.each(country, function (index, country) {
Dropdown1.append('<option value="' + country.CountryCode + '">' + country.Country + '</option>');
});
},
failure: function (msg) {
alert(msg);
}
});
}
function GetStates(Coun_code) {
var DdlState = $("#ddlState");
$.ajax({
type: "POST",
url: location.pathname + "/GetStates",
data: "{'CountryCode':'" + Coun_code + "'}",
contentType: "application/json;charset=utf-8",
datatype: "json",
success: function (response) {
var state = response.d;
$.each(state, function (index, state) {
DdlState.append('<option value="' + state.StateCode + '">' + state.StateName + '</option>');
});
},
failure: function (msg) {
alert(msg);
}
});
}
是否有像asp.net这样的Autopost返回属性在javascript中?
答案 0 :(得分:-1)
这可能会发生,因为我在您所在国家/地区的部分添加了返回false,所以请删除此。我没有尝试过这个
$(document).ready(function () {
bindData();
BindCountry();
var DropDown1 = $("#ddlCountry");
DropDown1.change(function (e) {
var CountryCode = DropDown1.val();
if (CountryCode >= 1) {
GetStates(CountryCode);
}
});
});
function BindCountry() {
var Dropdown1 = $("#ddlCountry");
$.ajax({
type: "POST",
url: location.pathname + "/GetCountry",
data: "{}",
contentType: "application/json;charset=utf-8",
datatype: "json",
success: function (response) {
var country = response.d;
$.each(country, function (index, country) {
Dropdown1.append('<option value="' + country.CountryCode + '">' + country.Country + '</option>');
});
},
failure: function (msg) {
alert(msg);
}
});
t
}
function GetStates(Coun_code) {
var DdlState = $("#ddlState");
$.ajax({
type: "POST",
url: location.pathname + "/GetStates",
data: "{'CountryCode':'" + Coun_code + "'}",
contentType: "application/json;charset=utf-8",
datatype: "json",
success: function (response) {
var state = response.d;
$.each(state, function (index, state) {
DdlState.append('<option value="' + state.StateCode + '">' + state.StateName + '</option>');
});
},
failure: function (msg) {
alert(msg);
}
});
return false;
}
Hope this will work.
