I am trying to post a data and trying to return from controller to back again and show it to alert box but dont know why this is not working
here is the controller code
[HttpPost]
public ActionResult getRequirmentsByProject(string projectname)
{
return Json(projectname, JsonRequestBehavior.AllowGet);
}
and here is my front end code
<input id="projName" type="text" name="Name" required="" value="javascript">
and this is my script code
var projectname = document.getElementById('projName').value;
$.ajax({
url: '/Worksheet/getRequirmentsByProject',
type: 'post',
data: { projectname },
contentType: 'application/json; charset=utf-8',
success: function (html) {
alert(html);
},
error: function (error) {
$(that).remove();
DisplayError(error.statusText);
}
});
In your case, I am giving you a simple example on how you can POST your form variables to your controller using AJAX:
<script type="text/javascript">
var projectname = document.getElementById('projName').value;
var json = {
projectname: projectname
};
$.ajax({
url: '#Url.Action("getRequirmentsByProject", "Worksheet")',
type: 'post',
dataType: "json",
data: { "json": JSON.stringify(json)},
success: function (data) {
alert(data);
},
error: function (error) {
$(that).remove();
DisplayError(error.statusText);
}
});
</script>
And in your controller, you can get this value as:
using System.Web.Script.Serialization;
[HttpPost]
public ActionResult getRequirmentsByProject(string json)
{
var serializer = new JavaScriptSerializer();
dynamic jsondata = serializer.Deserialize(json, typeof(object));
//Get your variables here from AJAX call
string projectname= jsondata["projectname"];
return Json(projectname);
}
its httpget and writing with a wrong way
[HttpGet]
public ActionResult getRequirmentsByProject(string projectname)
{
return Json(projectname, JsonRequestBehavior.AllowGet);
}
this is the right way thankyou for pointing out

using the following script, I am trying to access the variables being sent using data in the ajax function but I couldn't.
<script>
$('#inline-username').click(function () {
var comments = $('#inline-username').val();
//var selectedId = $('#hdnSelectedId').val();
$.ajax({
url: '#Url.Action("UpdateOrder")', // to get the right path to controller from TableRoutes of Asp.Net MVC
dataType: "json", //to work with json format
type: "POST", //to do a post request
contentType: 'application/json; charset=utf-8', //define a contentType of your request
cache: false, //avoid caching results
data: { test: $(this).text() }, // here you can pass arguments to your request if you need
success: function (data) {
// data is your result from controller
if (data.success) {
alert(data.message);
}
},
error: function (xhr) {
alert('error');
}
});
});
here is the action in the controller
public ActionResult UpdateOrder()
{
// some code
var test = Request.Form["test"];
return Json(new { success = true, message = "Order updated successfully" }, JsonRequestBehavior.AllowGet);
}
I tried Request.Form["test"] but the value of it is null. how should I receive the objects of data?
Your ActionResult is GET And you have no input parameter for your ActionResult so either change those or see below:
<script>
$('#inline-username').click(function () {
var comments = $('#inline-username').val();
//var selectedId = $('#hdnSelectedId').val();
$.ajax({
url: /ControllerName/ActionName
dataType: "json",
type: "GET",
contentType: 'application/json; charset=utf-8', //define a contentType of your request
cache: false,
data: { test: comments },
success: function (data) {
// data is your result from controller
if (data.success) {
alert(data.message);
}
},
error: function (xhr) {
alert('error');
}
});
});
Then within your controller:
public ActionResult UpdateOrder(string test)
{
// some code
return Json(new { success = true, message = "Order updated successfully" }, JsonRequestBehavior.AllowGet);
}
Update
Remember if you want to use POST then action you are calling has to be [HttpPost] like:
[HttpPost]
public ActionResult Example()
When there is no HTTP above your ActionResult Then Its By Default Get.
The action method should be decorated with the [HttpPost] attribute. Have you used the debugger to ensure that you're actually calling in to that method?
You can always just define a view model in C# and then accept that as a parameter to your post method - Asp.MVC will parse the post data for you as long as the names of the values are the same as your model.
Have you marked your action method with [HttpPost] attribute. ?
This post helped me a lot. I did the GET but POST raise an Internal Server Error just with [HttpPost]:
[HttpPost]
public ActionResult SaveOrder(int id, string test, string test2)
So i had to set params data with JSON.stringify and it worked. My full ajax request for POST:
$.ajax({
url: "/Home/SaveOrder",
dataType: "json",
type: "POST",
contentType: 'application/json; charset=utf-8', //define a contentType of your request
cache: false,
data: JSON.stringify({ id:2, test: "test3", test2: "msj3" }),
success: function (data) {
// data is your result from controller
if (data.success) {
alert(data.message);
}
},
error: function (xhr) {
alert('error');
}
});
I trying send data to my controller. Controller sends all data to client correcly but from client to controller not..
My front code:
$(document).ready(function () {
$("#MessageSend").click(function () {
var serviceURL = '/User/Chat';
var model = {
Message: $("#Message").val()
}
$.ajax({
type: "POST",
url: serviceURL,
data: model,
contentType: "application/json; charset=utf-8",
dataType: "json",
success: successFunc,
error: errorFunc
});
function successFunc(data, status) {
alert(data);
}
function errorFunc() {
alert('error');
}
});
});
And my controller, I have two versions - non of those versions works.
[HttpPost]
public IActionResult Chat(ChatMessage model)
{
Console.WriteLine(model.Message);
return Json("chamara");
}
and
[HttpPost]
public IActionResult Chat(string Message)
{
Console.WriteLine(Message);
return Json("chamara");
}
Thank you for help.
The JSON.stringify() method converts a JavaScript value to a JSON string, hence
You need to change the data in a way that the Json can "understand" it
for that change to
data: JSON.stringify(model)
for more information about it look Here
Looking at your code, seems you are trying to send a JSON to User controller but your controller is expecting a string (controller example 2).
Also, it is a good practice to create specific classes for binding events via jquery such as "js-messageSend". It will minimize the chance of your script breaking if you need to change the Message class for any reason in the future, but forget that you have an event on it.
Try this:
$(document).ready(function () {
$("#MessageSend").click(function () {
var messageText = $("#Message").val();
$.ajax({
type: "POST",
url: '/User/Chat',
data: { Message: messageText },
success: successFunc,
error: errorFunc
});
function successFunc(data, status) {
alert(data);
}
function errorFunc() {
alert('error');
}
});
});
I am trying to pass the data of the view model to one js method and from there I need to pass the VM to another controller method to show the data.
here is what I have did:
$(document).ready(function () {
var content = GetHomeContent('/Home/CastContent');
if (content) {
saveBDContent('/Message/Details/', content);
}
});
function GetHomeContent(url) {
var modelData;
$.ajax({
url: url,
cache: false,
async: false,
type: "GET",
contentType: 'application/json',
success: function (data) {
if (data) {
modelData = data;
}
},
error: function (data) {
status = false;
}
})
return modelData;
};
function saveBDContent(url, data) {
var status = false;
$.ajax({
url: url,
cache: false,
async: false,
type: "GET",
data: JSON.stringify(data),
contentType: 'application/json',
success: function (data) {
if (data == "200") {
status = true;
}
},
error: function (data) {
status = false;
}
})
return status;
};
The problem am facing is , the content I retrived from the method show the namespace of the ViewModel. When I pass that to the new controlled the Viewmodel content is coming null.
Do I need to add anything to get/Pass the proper content ?
The Dummy method skeleton
public ActionResult CastContent()
{
CastVM broadcastVM = new CastVM();
return Json( broadcastVM);
}
I have missed out the JsonRequestBehavior.AllowGet in my controller method, I have added and the results are coming perfectly.
public ActionResult CastContent()
{
CastVM broadcastVM = new CastVM();
return Json( broadcastVM,JsonRequestBehavior.AllowGet);
}
and also I have set the HTTP status as post in the jquery method
Do something like that in the Controller:
public JsonResult QuickSave(BookEntry bookEntry) {
YourViewModel model = new YourViewModel();
return Json(model);
}
EDIT >> The associated Javascript code is :
$.ajax({
type: "POST",
url: 'The URL',
data: 'The JSON data',
dataType: "json",
success: function (theViewModel) {
// Do some JS stuff with your model
},
error: function (xhr, status, error) {
// Do some error stuff
}
});
I am trying to pass an array variable from ajax to controller,
but I am not getting the values in controller
below is my code
AJAX
function userDetailsClass() {
var userDetails = {};
userDetails.age = 12;
userDetails.Name = "Vignesh";
userDetails.lastName = "s";
debugger;
$.ajax({
url: "Home/userDetails",
data: JSON.stringify({
UserDetailsParam: userDetails
}),
responseType: "json",
success: successfn,
error: errorfn
});
function successfn(result) {
};
function errorfn(result) {
};
}
Controller
public ActionResult userDetails( string UserDetailsParam){
return View();
}
I also tried
public ActionResult userDetails( string[] UserDetailsParam){
return View();
}
Your code should be like this
$.ajax({
url: "Home/userDetails",
data: {
"UserDetailsParam":JSON.stringify(userDetails)//change this
},
responseType: "json",
success: successfn,
error: errorfn
});
Try with this
var userDetails = {"age":'12',"Name":'Vignesh',"lastName":'s'};
$(document).ready(function () {
$.ajax({
url: 'LeadPipes/LeadCounts',
type: 'POST',
contentType: 'application/json',
async: false,
success: function (data) {
alert(data)
}
});
});
I am using the ajax call above to get a model back how would i use the model object in the success function. As in I need to be able to use the data like a views model like #model.Type lets say. how could i do that with the json data in the success?
The data object contains the properties passed down via the server.
You can then access them like:
var name = data.Name;
var testData = data.TestData;
Your Action could look like:
public JsonResult LeadCounts()
{
return Json(new { name = "Darren", testData = "Testing" });
}
In MVC3 you could do it like this:
public ActionResult LeadCounts()
{
var data = new { Count = 1, Something = "Something" };
return Json(data, JsonRequestBehavior.AllowGet);
}
In view:
$(document).ready(function () {
$.ajax({
url: 'LeadPipes/LeadCounts',
type: 'POST',
contentType: 'application/json',
async: false,
success: function (data) {
alert(data.Count);
}
});
});
