When I pass formdata in ajax call after json return it does not return on Success or error block just printing value on browser
// And my Controller side code is
[HttpPost]
public JsonResult Create(InquiryModel model)
{
var inquiry = _inquiryService.GetInquiryById(model.Id);
return Json(inquiry.Id, JsonRequestBehavior.AllowGet);
}
// View side
var formData = new FormData();
jQuery.each(jQuery('#QuotationDocument')[0].files, function (i, file) {
formData.append('file-' + i, file);
});
$.ajax({
url: '#Url.Action("Create", "Inquiry")',
data: formData,
contentType: false,
processData: false,
type: "POST",
success: function (data) {
alert("ssss");
},
error: function (msg) {
alert("error", msg.statusText + ". Press F12 for details");
}
});
when I pass only formData it works fine
Try like this;
$.ajax({
url: '#Url.Action("Create", "Inquiry")',
data: formData,
datatype: "json",
type: "POST",
success: function (data) {
alert("ssss");
},
error: function (msg) {
alert("error", msg.statusText + ". Press F12 for details");
}
});
In the below code I have a textbox .My aim is when I focus on textbox it will call the server side code through ajax.But I got a error unknown web method txtField_GotFocus parameter name method name.Please help me to rectify the error.
design code:
$(document).ready(function () {
$("#<%=txtField.ClientID%>").bind("focus", function () {
$.ajax({
type: "POST",
url: "<%=Request.FilePath%>/txtField_GotFocus",
data: "{}",
contentType: "application/json",
dataType: "json",
success: function (msg) {
//alert("success message here if you want to debug");
},
error: function (xhr) {
var rawHTML = xhr.responseText;
var strBegin = "<" + "title>";
var strEnd = "</" + "title>";
var index1 = rawHTML.indexOf(strBegin);
var index2 = rawHTML.indexOf(strEnd);
if (index2 > index1) {
var msg = rawHTML.substr(index1 + strBegin.length, index2 - (index1 + strEnd.length - 1));
alert("error: " + msg);
} else {
alert("General error, check connection");
}
}
});
});
});
<asp:TextBox ID="txtField" runat="server" AutoPostBack="true" OnTextChanged="txtField_TextChanged" ClientIDMode="Static"></asp:TextBox>
field.ascx:
public static void txtField_GotFocus()
{
string foo = HttpContext.Current.Request["foo"];
//code...
}
You are missing [WebMethod] annotation. Also i have modified your code
[WebMethod]
public static string txtField_GotFocus()
{
string foo = HttpContext.Current.Request["foo"];//oops i got my super data
//code...
return "awesome, it works!";
}
Check this Article
Your refactored ajax code
$(document).ready(function () {
$("#<%=txtField.ClientID%>").bind("focus", function () {
$.ajax({
type: "POST",
url: "<%=Request.FilePath%>/txtField_GotFocus",
data: "{foo:'whatever'}",
success: function (msg) {
alert(msg);//awesome, it works!
},
error: function (xhr) {
}
});
});
});
Data returned form Server is stored in msg.d field. If you return a single value, you should get it using msg.d. If you return a JSON serialized object you have to parse it using JSON.parse(msg.d)
$(document).ready(function () {
$("#<%=txtField.ClientID%>").bind("focus", function () {
$.ajax({
type: "POST",
url: "<%=Request.FilePath%>/txtField_GotFocus",
data: "{foo:'whatever'}",
success: function (msg) {
alert(msg.d);//awesome, it works!
},
error: function (xhr) {
}
});
});
});
I am unable to redirect to another after successful login through my webservice. I am getting correct response from web service But page doesn't redirect.
<script type="text/javascript">
function registerUser() {
try {
var username = document.getElementById("UserName");
var pwd = document.getElementById("Password");
$.ajax({
datatype: "json",
type: "POST",
url: "http://localhost:51290/CMSWebService.asmx/LoginUser",
data: "{'username':'" + username.value + "','pwd':'" + pwd.value + "'}",
async:false,
contentType: "application/json; charset=utf-8",
success: function (data) {
alert("hello");
window.location.replace("default.aspx");// to redirect error occurs here
},
error: function (data) {
debugger;
if (data.d) {
}
}
});
}
catch (e) {
debugger;
alert(e);
}
}
</script>
Why don't you try window.location.replace(" full url of your page ") .
<script type="text/javascript">
function registerUser() {
try {
var username = document.getElementById("UserName");
var pwd = document.getElementById("Password");
$.ajax({
datatype: "json",
type: "POST",
url: "http://localhost:51290/CMSWebService.asmx/LoginUser",
data: "{'username':'" + username.value + "','pwd':'" + pwd.value + "'}",
async:false,
contentType: "application/json; charset=utf-8",
success: function (data) {
window.location = "./default.aspx";
alert("hello");
},
error: function (data) {
debugger;
if (data.d) {
}
}
});
}
catch (e) {
debugger;
alert(e);
}
}
</script>
Try this
I want to create an Autocomplete field for a search option. I have tried with following code.
But the web method doesn't fire when the Autocomplete function is execution.
What will be the reason ?
Here is the jQuery function:
<script type="text/javascript">
$(function () { $("#<%=tags.ClientID %>").autocomplete({
source:function (request, response) {
$.ajax ({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "~/Services/AutoComplete.asmx/GetFarmersByName",
data: "{ 'name' : '" + $("#<%=tags.ClientID %>").val() + "'}",
dataType: "json",
async: true,
dataFilter: function (data) { return data; },
success: function (data) {
response($(data.d, function (item) {
return {
value: item.AdrNm
}
}));
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert(textStatus);
}
});
}
});
});
</script>
Here is the web method
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public List<FMISPersonalDataViewByName_Result> GetFarmersByName(string name)
{
this._personalData = new personalData();
int cky = 45;
CdMa cdMas = new CdMa();
cdMas = this._personalData.getcdMasByConcdCd2(cky, "AdrPreFix", true);
int prefixKy = cdMas.CdKy;
List<FMISPersonalDataViewByName_Result> list = new List<FMISPersonalDataViewByName_Result>();
list = this._personalData.GetPersonalDataByName(prefixKy, cky, name);
return list;
}
Make sure you hit the webservice function by having breakpoint on your service function. Please change your script to below:
<script type="text/javascript">
$(function () {
$("#<%=tags.ClientID %>").autocomplete
({
source:
function (request, response) {
$.ajax
({
url: " <%=ResolveUrl("~/Services/AutoComplete.asmx/GetFarmersByName") %>",
data: "{ 'name' : '" + $("#<%=tags.ClientID %>").val() + "'}",
dataType: "json",
type: "POST",
contentType: "application/json; charset=utf-8",
async: true,
dataFilter: function (data) { return data; },
success: function (data)
{
response($(data.d, function (item)
{
return
{
value: item.AdrNm
}
}));
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert(textStatus);
}
});
}
});
});
</script>
Above your service class add [System.Web.Script.Services.ScriptService]
Or you can do this in an asp.net page!
add the static keyword and change the webservice to ASP.NET page!
public static string GetFarmersByName(string name)
For example:
A.aspx:
$.ajax({
type: "POST",
url: "A.aspx/GetSN",
data: {},
contentType: "application/json;charset=utf-8",
dataType: "json",
async:false,
success: function (json) {
var msg = JSON.parse(json.d);
sn = msg;
},
failure: function () {
alert("Sorry,there is a error!");
}
});
Then in your A.aspx.cs type in:
[WebMethod]
public static string GetSN()
{
Random RN = new Random();
string year = DateTime.Now.ToString("yy").ToString();
string MonAndDate = DateTime.Now.ToString("MMdd").ToString();
string Hour = DateTime.Now.ToString("HHMMss").ToString() + DateTime.Now.Millisecond.ToString() + RN.Next(100, 900).ToString();
string SerialNumber = year + MonAndDate + Hour;
return JsonConvert.SerializeObject(SerialNumber);
}
Assuming tags as your textbox, set data as { 'name': '" + request.term + "'}
$("#<%=tags.ClientID %>").autocomplete({
source: function (request, response) {
$.ajax({
url: "Services/AutoComplete.asmx/GetFarmersByName",
data: "{ 'name': '" + request.term + "'}",
dataType: "json",
type: "POST",
contentType: "application/json; charset=utf-8",
success: function (data) {
response($.map(data.d, function (item) {
return {
label: item.split('-')[0],
val: item.split('-')[1]
}
}))
},
error: function (response) {
alert(response.responseText);
},
failure: function (response) {
alert(response.responseText);
},
});
},
minLength: 0,
focus: function () {
// prevent value inserted on focus
return false;
},
});
debug on method GetFarmersByName,
NOTE: Check have you uncomment [System.Web.Script.Services.ScriptService] on .asmx page.
Post again!!!

Paste this method inside code behind file where you are calling this method. Change url to url: "Test.aspx/GetFarmersByName" and then test it. Its much clean code rather then Web Service.
using System.Web.Script.Services;
[WebMethod]
[ScriptMethod(UseHttpGet = false, ResponseFormat = ResponseFormat.Json)]
public List<string> GetFarmersByName(string aaa)
{
List<string> list = new List<string>();
list.Add(aaa);
return list;
}
try this -
<script type="text/javascript">
$(function () { $("#<%=tags.ClientID %>").autocomplete({
source:function (request, response) {
var obj = JSON.Stringfy("{ 'name' : '" + $("#<%=tags.ClientID %>").val() + "'}");
$.ajax ({
type: "POST",
url: "~/Services/AutoComplete.asmx/GetFarmersByName",
data: obj,
contentType: "application/json; charset=utf-8",
dataType: "json",
async: true,
dataFilter: function (data) { return data; },
success: function (data) {
response($(data.d, function (item) {
return {
value: item.AdrNm
}
}));
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert(textStatus);
}
});
}
});
});
and the webmethod-
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public List<FMISPersonalDataViewByName_Result> GetFarmersByName(string name)
{
this._personalData = new personalData();
int cky = 45;
CdMa cdMas = new CdMa();
cdMas = this._personalData.getcdMasByConcdCd2(cky, "AdrPreFix", true);
int prefixKy = cdMas.CdKy;
List<FMISPersonalDataViewByName_Result> list = new List<FMISPersonalDataViewByName_Result>();
list = this._personalData.GetPersonalDataByName(prefixKy, cky, name);
return list;
}
I need to call a server side method from JavaScript function in ASP.Net 2.0 framework. How can I do this?
Try This
function focuslost() {
mainForm.StartUpdating();
var pagePath = window.location.pathname;
$.ajax({
type: "POST",
url: pagePath + "/TextChanged",
data: ("{ 'pNTID':'" + $("#<%= txtNTID.txtClientId%>").val()) + "'}",
contentType: "application/json; charset=utf-8",
dataType: "json",
error: function(XMLHttpRequest, textStatus, errorThrown) {
mainForm.EndUpdating()
},
success:
function(result) {
if (result.d.length > 0) {
}
mainForm.EndUpdating()
}
});
}
[WebMethod]
public static string TextChanged(string pNTID)
{
retrun "";
}
Use WebMethod or AjaxMethod. Check Below
