i am trying to post my string called 'selected' trough my $.ajax call but the controller(selected=null) receives a null value? selected has a value ({'selected':0100}) according to fiddler?
[HttpPost]
public ActionResult Index(string selected)
{
return Json(new {value = "this is a test"});
}
$(document).ready(
$("#btnSave").click(
function () {
var checkboxesselected = "0100";
$.ajax({ type: 'POST',
url: "/Home/Index",
datatype: 'json',
data: "{'selected':" + checkboxesselected + "}"
});
}
)
The problem is you're sending the data to jQuery as a string literal as opposed to an object. Your line with the data parameters should be data: {selected: checkboxesselected }
You're missing the quotes around "checkboxesselected "
$(document).ready(
$("#btnSave").click(
function () {
var checkboxesselected = "0100";
$.ajax({ type: 'POST',
url: "/Home/Index",
datatype: 'json',
data: "{ 'selected' : '" + checkboxesselected + "'}"
});
}
)
try:
var val = { selected: checkboxesselected };
and then:
...
datatype: 'json',
data: val
...

My application has multiple data like Text-box value, label value, Drop-Down value,File Data and send same data at server side and store in database
To achieve this, i have used below method but now i want to use Formdata and append each value and send it to server side
How to achieve this scenario using Formdata with specific object type.
Below is the code
var selectedText = $('#Commentinput').text();
$('#actioncomments').text(selectedText);
var debitEntityValue = $('#DrAccount option:selected').text();
var creditEntityValue = $('#CrAccount option:selected').text();
var amount = $("#Amountinput").val();
var paymentActionReason = $('#action').text();
var paymentCommentReason = $('#Commentinput').val();
var prepayAccountId =#Model.prepaidBranchList.PrepaidID;
var transactionDate = '#DateTime.Today';
var transactionExtensions = "1";
var fileBase64Data = $("#fileUpload").text();
if ($('#Commentinput').val() == "") {
paymentCommentReason = "No Comment";
}
else {
paymentCommentReason = $('#Commentinput').val();
}
var adjustmentTransactioninfo =
{
PaymentReasonMasterId: paymentReasonMasterId,
DebitEntityValue: debitEntityValue,
CreditEntityValue: creditEntityValue,
Amount: amount,
PaymentActionReason: paymentActionReason,
PaymentCommentReason: paymentCommentReason,
PrepayAccountId: prepayAccountId,
TransactionDate: transactionDate,
TransactionExtensions: transactionExtensions
};
var data = JSON.stringify({
'adjustmentTransactioninfo': adjustmentTransactioninfo,
'fileData': 0
});
var url = "#Html.Raw(Url.Action("AdjustmentTransaction",
"PrepaidActivity"))";
url += '?branchCode=' + '#Model.prepaidBranchList.IASBranchCode'
$.ajax({
url: url,
traditional: true,
data: data,
enctype:"multipart/form-data",
contentType: "application/json charset=utf-8",
dataType: "json",
type: 'POST',
success: function (data) {
$("#ajaxLoader").show();
if (data != null) {
var ProductActionID = data.SuccessMessage.split(':');
uploadFile.append('ProductActionID' , ProductActionID[1]);
FileUpload(uploadFile);
var dialog = document.querySelector('#Finaldialog');
var ConfirmationScreen = $("<p></p>").text(data.SuccessMessage);
$("#finalmdl-dialog").append(ConfirmationScreen);
dialog.showModal();
dialog.querySelector('button:not([disabled])').addEventListener('click', function() {
dialog.close();
location.reload();
});
}
}
});`
Controller code
public JsonResult AdjustmentTransaction(TraxAdjustmentTransactionInfo adjustmentTransactioninfo, string fileData, string branchCode)
{
PrepaidAdminService.PrepaidAdminDashBoardServiceClient _PrepaidAdminService = new PrepaidAdminService.PrepaidAdminDashBoardServiceClient();
TraxAdjustmentTransactionResult result;
adjustmentTransactioninfo.ProductActionMasterId = Convert.ToInt16(System.Configuration.ConfigurationManager.AppSettings["ProductActionMasterId"]);
adjustmentTransactioninfo.ProductCode = Convert.ToString(System.Configuration.ConfigurationManager.AppSettings["ProductCode"]);
adjustmentTransactioninfo.DebitEntityMasterId = TraxEntityType.GPLedgerAccount;
adjustmentTransactioninfo.CreditEntityMasterId = TraxEntityType.GPLedgerAccount;
adjustmentTransactioninfo.UserId = Utility.UserID;
adjustmentTransactioninfo.RetailerId = _PrepaidAdminService.GetBranchRetailerId(branchCode);
use serializeArray and can be add the additional data:
var data = $('form').serializeArray();
data.push({name: 'Amit', value: 'love'});
$.ajax({
type: "POST",
url: "url",
data: data,
success: function(data) {
// do what ever you want with the server response
},
error: function() {
alert('error handing here');
}
});
Remove the #Html.Raw(Url.Action()), contentType and JSON.stringify() and leave that to the ModelBinder. Change your ajax to this:
$.ajax({
url: '#Url.Action("AdjustmentTransaction", "PrepaidActivity")',
traditional: true,
data: {
adjustmentTransactioninfo: adjustmentTransactioninfo,
fileData: "0",
branchCode: '#Model.prepaidBranchList.IASBranchCode'
},
enctype: "multipart/form-data",
type: 'POST',
success: function (data) {
alert("success");
}
});
var params = { param1: value, param2: value2}
$.ajax({
type: 'POST',
contentType: 'application/json; charset=utf-8',
url: '../aspxPage.aspx/methodName',
data: JSON.stringify(params),
datatype: 'json',
success: function (data) {
var MethodReturnValue = data.d
},
error: function (xmlhttprequest, textstatus, errorthrown) {
alert(" conection to the server failed ");
}
});
// Param1 and param2 name should be same as method argument
I am trying to pass two parameters on an ajax call. I already tried several ways suggested on StakeOverflow but none worked. Here is my method signature on controller:
[HttpPost]
public ActionResult UploadFile(HttpPostedFileBase[] files, string[] usersToShare)
Here is my function:
function uploadFile() {
var formData = new FormData();
var totalFiles = document.getElementById("files").files.length;
for (var i = 0; i < totalFiles; i++) {
var file = document.getElementById("files").files[i];
formData.append("files", file);
}
//get the selected usernames (email) to share the file
var selectedUsers = [];
$("#costumerUsersListSelect :selected").each(function () {
selectedUsers.push($(this).val());
});
$.ajax({
type: 'post',
url: '/ManageFiles/UploadFile',
data: "files=" + formData + "usersToShare=" + selectedUsers,
dataType: 'json',
contentType: false,
processData: false,
success: function (data) {
},
error: function (error) {
}
});
}
So I want to pass to the controller the formData and the selectedUsers. If I pass just the formData (Data: formData) everything works but I need to pass the selectedUsers too.
Here what I already tried without any success:
data: JSON.stringify({ files: formData, usersToShare: selectedUsers }),
data: { files: formData, usersToShare: JSON.stringify(selectedUsers)},
data: "files=" + formData + "&usersToShare=" + selectedUsers,
data: "files=" + formData + "usersToShare=" + selectedUsers,
I am not sure if this is a syntax issue.
Thanks in advance for any help.
Instead of:
data: "files=" + formData + "usersToShare=" + selectedUsers,
append the selectedUsers in formData and send only formData to the server like:
data: formData,
and try again.
You need to use different keys for each value you append to formData, and then just append both files and users the same way
function uploadFile() {
var formData = new FormData();
var allFiles = $("#files").get(0).files;
for (var i = 0; i < allFiles.length; i++) {
formData.append("files_" + i, allFiles[i]);
}
$("#costumerUsersListSelect :selected").each(function(_,i) {
formData.append('user_' + i, this.value);
});
$.ajax({
type: 'post',
url: '/ManageFiles/UploadFile',
data: formData,
dataType: 'json',
contentType: false,
processData: false,
success: function(data) {},
error: function(error) {}
});
}
in your ajax:
data: JSON.stringify(obj);
before your ajax statement, define your parameters like:
var obj = { files: formData , usersToShare: selectedUsers };
I'm picking up items from a ul, and turning into an array. My controller is below and the variable items is getting empty.
What should I do to the controller receiving the correct value.
Controller:
[AcceptVerbs(HttpVerbs.Get)]
public JsonResult GravarConfiguracao(string[] itens)
{
var indicaores = itens;
var sequencia = 1;
foreach (var item in indicaores)
{
var atualizaIndicador = IndicadoresDoUsuario.AtualizarSequencia(Usuario.Codigo, Convert.ToInt32(item), sequencia);
sequencia++;
}
return Json(new { HttpStatusCode.OK });
}
JQuery:
$.ajax({
type: 'GET',
url: makeUrl("Indicador/GravarConfiguracao"),
data: JSON.stringify({ itens: $("#sort1").sortable('toArray') }),
dataType: 'json',
contentType: 'application/json',
success: function (dados) {
},
error: function (err) {
alert("Erro: - " + err);
}
});
JQuery send:
Query String Parameters:
{"itens":["itemIndicador_3","itemIndicador_10","itemIndicador_11"]}:
I have a simple web service with one argument :
public static string LoadComboNews(string id)
{
string strJSON = "";
DataRowCollection people = Util.SelectData("Select * from News where person = "+ id +" Order by NewsId desc ");
if (people != null && people.Count > 0)
{
//temp = new MyTable[people.Count];
string[][] jagArray = new string[people.Count][];
for (int i = 0; i < people.Count; i++)
{
jagArray[i] = new string[] { people[i]["NewsID"].ToString(), people[i]["Title"].ToString() };
}
JavaScriptSerializer js = new JavaScriptSerializer();
strJSON = js.Serialize(jagArray);
}
return strJSON;
}
on javascript I am trying to call it with parameter :
jQuery.ajax({
type: "POST",
url: "webcenter.aspx/LoadComboNews",
data: "{'id':usrid}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (msg) {
// Replace the div's content with the page method's return.
combonews = eval(msg.d);
}
});
UPDATE:
usrid is dynamic
Am I doing something wrong here?
data you are sending is invalid "{'id':usrid}"
this not a valid json
probably what you wanna do is assuming usrid is a variable
"{\"id\":"+usrid+"}"
with it shoudnt you be executing this command
Select * from News where person = '"+ id +"' Order by NewsId desc
Considering id is a string
also try this
combonews = JSON.stringify(msg);
Add WebMethod to the method
[WebMethod]
public static string LoadComboNews(string id)
And try this format
$.ajax({
type: "POST",
url: "webcenter.aspx/LoadComboNews",
data: '{"id":"usrid"}',
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (msg) {
// Replace the div's content with the page method's return.
alert(msg.d);
},
error: function (jqXHR, textStatus, errorThrown) {
console.log(textStatus, errorThrown);
alert(textStatus + " " + errorThrown);
}
});
Or
data: '{"id":"' + usrid + '"}',
JavaScriptSerializer jss = new JavaScriptSerializer();
var seferim = jss.Serialize(sefer);
string asds = seferim.ToString();
asds = HttpUtility.HtmlEncode(asds);
function otobusGetir(id, b, i) {
id = encodeURI(id);
$.ajax({
type: 'POST',
url: 'BiletSatis.aspx/Getir',
contentType: 'application/json;charset=utf-8',
dataType: 'json',
data: '{"id":"' + id + '","Binis":"' + b + '","Inis":"' + i + '"}',
success: function () { },
error: function () { }
})
[WebMethod]
public static string Getir(string id, string Binis, string Inis)
{
string a = id;
string b = HttpUtility.HtmlDecode(id);
return null;
}
The problem is javascript function cannot take parameter(Uncaught SyntaxError: Unexpected token ILLEGAL) which is serialized.How i can totally done tihs job?
The problem is that this is not working while javascript function run it can not take argument,how can totaly don this job
Try like this:
function otobusGetir(id, b, i) {
$.ajax({
type: 'POST',
url: 'BiletSatis.aspx/Getir',
contentType: 'application/json;charset=utf-8',
dataType: 'json',
data: JSON.stringify({ id: id, Binis: b, Inis: i }),
success: function () { },
error: function () { }
});
}
and to call the function:
otobusGetir(123, 'foo bar', 'baz');
and the page method:
[WebMethod]
public static string Getir(string id, string Binis, string Inis)
{
// don't use any Html decoding here. The parameters will
// already be properly formatted so you can use them directly
return null;
}
