I am passing an object to my controller like so:
var form = JSON.stringify({
"subRevisedRequest": $('#frmRevised').val(),
"subSubcontractor": $('#frmSubcontractor').val(),
"subDescription": $('#frmDesc').val(),
"subCostCode": $('#frmCostCode').val(),
"subAmt": $('#frmAmt').val(),
"subPaymentTerms": "terms",
"subRetainage": 10,
"subComments": $('#frmComment').val()
});
$.ajax({
url: '#Url.Action("CreateSubcontracts", "Routing")',
type: "POST",
datatype: "JSON",
contentType: "application/json; charset=utf-8",
data: form,
success: function(result) {
if (!result.success) {
$('#errormsg').empty();
$('#errormsg').append(result.message);
} else {
location.href = '#Url.Action("Index", "Home")';
}
},
error: function (result) {
alert("Failed");
}
});
my controller sees this as the object it is looking for:
public ActionResult CreateSubcontracts(RoutingSubcontracts s)
My problem is that I'd like to pass along just one more string. I know I can make a view specific model but I was wondering if I could do something like this for example:
public ActionResult CreateSubcontracts(RoutingSubcontracts s, string bu)
I have tried the the following with no luck:
data: JSON.stringify({ "s": form, "bu": "251" }),
but the complex object just comes through as null. Is there a way I can pass the object and a string through as well?
Try adding the string item in the JSON you already have. Dont stringify it or it will just send a big string that youll have to parse again on the server.
var form = {
"subRevisedRequest": $('#frmRevised').val(),
"subSubcontractor": $('#frmSubcontractor').val(),
"subDescription": $('#frmDesc').val(),
"subCostCode": $('#frmCostCode').val(),
"subAmt": $('#frmAmt').val(),
"subPaymentTerms": "terms",
"subRetainage": 10,
"subComments": $('#frmComment').val(),
"bu": "251" // add it here
};
$.ajax({
url: '#Url.Action("CreateSubcontracts", "Routing")',
type: "POST",
datatype: "JSON",
data: form,
success: function(result) {
if (!result.success) {
$('#errormsg').empty();
$('#errormsg').append(result.message);
} else {
location.href = '#Url.Action("Index", "Home")';
}
},
error: function (result) {
alert("Failed");
}
});
In your view jquery create a second var for bu. Assign the data in you ajax call like this;
data: { "s" : form, "bu" : "251" }
In your controller method change the signature to include a default value for bu like this;
public ActionResult CreateSubcontracts(RoutingSubcontracts s, string bu = "NoValue")
With the default value set bu will act like an optional parameter

I have the following ajax in a .chtml file:
var planID = $("#PlanID").val();
if (planID.length == 4) {
$(ctl).prop("disabled", true).text(msg);
$("#nextButton").prop("disabled", true);
setTimeout(function () {
$(".submit-progress").removeClass("hidden");
}, 1);
$.ajax({
type: "POST",
url: "/ForgotUserID/CheckPlanID",
data: '{planID: "' + planID + '" }',
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (response) {
console.log("ajax success function");
$("form").submit();
},
failure: function (response) {
alert(response.responseText);
},
error: function (response) {
alert(response.responseText);
}
});
//$("form").submit()
}
And I have the following in my ForgotUserIDController:
[HttpPost]
public JsonResult CheckPlanID(string planID)
{
ForgotUserID forgotUserID = new ForgotUserID()
{
PlanID = planID
};
return Json(forgotUserID);
}
When I run the code, I see this in the dev tools under network:
So I know the data that I typed into my input box is floating around somewhere.
When I have a breakpoint set in my controller, the value of planID is null. Shouldn't the value get passed from the ajax data component?
How can I get the data typed into the input box passed to my controller?
Any assistance is greatly appreciated.
Thank you!
if you want to use contentType: "application/json; charset=utf-8",
fix ajax data line
data: JSON.stringify({ planID : planID }),
and create viewmodel and use frombody attribute in action
public JsonResult CheckPlanID([FromBody] PlanViewModel model)
{
string planID=model.PlanID;
....
}
public class PlanViewModel
{
public string PlanID {get;set;}
}
or remove contentType: "application/json; charset=utf-8" and fix data
//contentType: "application/json; charset=utf-8",
data: { planID : planID },
in this case you don't need and extra class and frombody attribute. Leave your action header as it is
I have a few checkboxes on my page. I have some jquery in place to ensure that only one checkbox is checked at a time. I have assigned a specific value to each checkbox. The below ajax finds the checkbox that is checked and I'm grabbing the value associated to it. How do I pass that value to my action?
AJAX
$("input:checkbox").click(function () {
var PaymentID = document.querySelector('#chkBox:checked').value;
alert(PaymentID); // for test
$.ajax({
type: "POST",
dataType: "json",
data: PaymentID,
contentType: "application/json; charset=utf-8",
url: "#Url.Action("MyAction", "Home")",
success: function () {
return PaymentID; // Failed attempt at passing data.
}
})
})
Action:
[HttpPost]
public ActionResult MyAction(string PaymentID)
{
// Magic
}
Please keep in mind i am fairly new to ajax. Thx guys.
You can pass a javascript object with name PaymentID ( same name as your action method parameter)
data: { PaymentID: PaymentID },
You do not need to specify contentType as you are sending a simply object. Also you do not necessarily need to specify dataType for your ajax call to send the data.
This should work.
var PaymentID = "some value";
$.ajax({
type: "POST",
data: { PaymentID: PaymentID },
url: "#Url.Action("MyAction", "Home")",
success: function (response) {
console.log('response', response);
}
});
Or you can use the $.post method.
$.post("#Url.Action("MyAction", "Home")",{ PaymentID: PaymentID }, function(response) {
console.log('response', response);
});
I am getting error while I post Ajax request to controller method. In controller method I need to pass Model class object.
But it gives me 500 Internal server error.
Can anybody help me to make it correct?
Mu code is as per below:
jQuery:
var request = $("#frmHost").serialize();
$.ajax({
url: "/Host/HostItemDetails/" ,
type: "POST",
datatype: 'json',
contentType : "application/json",
data: request,
success: function (data) {
if (data == '1111') {
///Success code here
}
else if (data != '') {
jAlert(data);
}
}
});
Controller Method :
[HttpPost]
public JsonResult HostItemDetails(ClsHost objHost)
{
//Code here
return Json("1111");
}
Nirav Try this,
Parse the serialized data as a JSON object and later stringify that while posting using JSON.stringify().
$("#Button").click(function () {
var data = $("#frmHost").serialize().split("&");
var request = {};
for (var key in data) {
request[data[key].split("=")[0]] = data[key].split("=")[1];
}
$.ajax({
url: "/Home/HostItemDetails/",
type: "POST",
datatype: 'json',
contentType: "application/json",
data: JSON.stringify(request),
success: function (data) {
if (data == '1111') {
///Success code here
}
else if (data != '') {
jAlert(data);
}
}
});
});
I ran the same code that you are running.
To test the code I did the following changes. I took a button, and on click event I am sending the post back to the controller.
the '[HttpPost]' attribute is fine too.
Can you make one thing sure, that the frmHost data matches to the class ClsHost,but still that shouldn't cause the server error, the error will be different.
$(document).ready(function () {
$("#clickMe").click(function () {
var request = '{"Users":[{"Name":"user999","Value":"test"},{"Name":"test2","Value":"test"}]}';
$.ajax({
url: "/Home/HostItemDetails/",
type: "POST",
datatype: 'json',
contentType: "application/json",
data: request,
success: function (data) {
if (data == '1111') {
///Success code here
}
else if (data != '') {
jAlert(data);
}
}
});
});
});
Controller:
[HttpPost]
[ValidateAntiForgeryToken]
public JsonResult HostItemDetails(ClsHost objHost)
{
//Code here
return Json("111", JsonRequestBehavior.AllowGet);
}
It is solved by removing same property name in Model class. It is mistakenly added by me twice.
I am new with knockout and mvc, so I need some help, my question is
my dropdown list is populating successfully from server, and on clicking save button calls Save method in controller. But problem is that in controller I am unable to receive json data i.e it is null. here is my code in view
var initialData = #Html.Raw( new System.Web.Script.Serialization.JavaScriptSerializer().Serialize(Model));
var viewModel = function(){
var self = this;
self.HomeAgencies = ko.observableArray(initialData.HomeAgencies);
self.selectedOrgUnit = ko.observable();
self.Save = function () {
$.ajax({
url: "#Url.Action("Save")",
type: "POST",
data: ko.toJSON(this),
contentType: "application/json; charset=utf-8",
dataType:"json",
success: function(result) {alert(result.message)}
});
}
}
var vm = new viewModel();
ko.applyBindings(vm);
Where in controller i have following code
public JsonResult Save(string someData)
{
var message = string.Format("Saved {0} ", "successfully");
return Json(new { message });
}
string someData is always null, where I am expecting some json data.
Try to replace this to self in data and introduce field name and remove contentType.
$.ajax({
url: '#Url.Action("Save")',
type: 'POST',
data: { someData: ko.toJSON(self) },
dataType: 'json',
success: function (result) { alert(result.message); }
});
In your case context of the method can be changed from your object to html element that invoked them method or to window.
issue resolved. Problem was at controller side, in Action of controller pass the same model class instead parsing json manually.
I have this ajax code:
return $.ajax({
type: "POST",
url: "somefile.php",
cache:false,
data: { "yfilter": $("#yearFilter").serializeArray(),
"gfilter": $("#genreFilter").serializeArray() },
dataType:"json",
success: function(data){
alert("success");
}
This works fine, but I need to pass the data parameter dynamically. For now I need the above data parameter content and a single string.
How do I pass this dynamically? / How do I store it in a variable and pass it to the "data:" field?
{ "yfilter": $("#yearFilter").serializeArray(),
"gfilter": $("#genreFilter").serializeArray() }
I tried JSON.stringify I I couldn't get it to work probably due to the data being an array.
The year and genre arrays are coming directly from the jquery drop down menu. It is selected like by it's #id like so "$("#yearFilter")". This is the select form element.
<select multiple="multiple" name="yearFilter[]" class="filterChange" id="yearFilter">
What I need at the base level is:
var someData = "";
if(...){
someData = { "yfilter": $("#yearFilter").serializeArray(),
"gfilter": $("#genreFilter").serializeArray() };
}
else if(...){
someData = "sampleString";
}
And in ajax call:
...
data: someData,
...
I think I have an idea what you want but post has been overly complicated by extraneous issues like json stringify . Here's a function that could be used in several places eleswhere in your code to make one type of AJAX call or another.
You would then perhaps have several buttons and call the function within handlers for each type of button and change the argument passed to function
doAjax('someval');/* use in button 1*/
doAjax('someOtherval');/* use in button 2*/
function doAjax(arg) {
var someData = "";
if (arg == 'someval') {
someData = {
"yfilter": $("#yearFilter").val(),
"gfilter": $("#genreFilter").val()
};
} else {
someData = "sampleString";
}
$.ajax({
type: "POST",
url: "somefile.php",
cache: false,
data: someData,
dataType: "json",
success: function(data) {
if (arg == 'someval') {
alert("success 1");
} else {
alert("success 2");
}
}
})
}
Hope I've understood what you're asking for.
You could do something like this:
var parameters = {};
if (...) {
parameters = $("#yearFilter").serializeArray();
}
if () {
parameters = $("#genreFilter").serializeArray();
}
and then replace the line:
parameters: { "yfilter": $("#yearFilter").serializeArray(),
"gfilter": $("#genreFilter").serializeArray() },
with:
data: parameters,
JSON type should be best option for dynamically data. push whatever data you wish to inside json like shown below, Hence create your json dynamically and send as ajax data.
var employees = {
accounting: [],
dept: "HR"
};
employees.accounting.push({
"firstName" : item.firstName,
"lastName" : item.lastName,
"age" : item.age
});
$.ajax({
url: POSTURL,
type: 'POST',
dataType: 'json',
data : employees,
contentType: 'application/json; charset=utf-8',
success: function (results)
{
},
error: function (results)
{
jQuery.error(String.format("Status Code: {0}, ", results.status, results.statusText));
}
});
Try it:
someData = JSON.stringify({ yfilter: $("#yearFilter").val(), gfilter: $("#genreFilter").val() });
It will work.
