In my controller:
public ActionResult ViewPage()
{
Obj object = new Obj();
object.id = 3;
var JsonItem = Model.getItem(object);
return Json(JsonRfc, JsonRequestBehavior.AllowGet);
}
Client-side
$(document).ready(function () {
$.getJSON({
url: 'ViewPage',
function(data) {
console.log(data);
}
});
});
I'm not logging anything in my console (console.log(data) returns nothing). What am I missing here? When I click on the ActionLink ViewPage, it should go into the model and do some stuff. After I want to get it from the client-side to generate a list view.
Perhaps you are missing something.
Try
$(document).ready(function () {
$.getJSON({
url: 'ViewPage',
success: function(data) {
console.log(data);
}
});
});

I have the follow Ajax call that points to a controller function:
<script type="text/javascript">
$(document).ready(function () {
$('#AddNote').click(function () {
$('#AddNote').addClass("disabled");
var txtNote = document.getElementById('note');
var result = document.getElementById('result');
result.innerText = "Adding note...";
$.ajax({
url: "#Url.Action("AddNoteAsync", "Leads")",
type: "POST",
data: { leadId: #Model.Id, note: txtNote.value },
async: true,
success: function (data) {
// removed
},
});
});
});
</script>
When I click the AddNote button I see the "Adding note..." message display and then nothing else happens. When I check the console in chrome, it reads:
:44309/Leads/AddNoteAsync:1 - Failed to load resource: the server responded with a status of 400 ()
So I know 400 means bad request but I'm not sure why it's happening. I've tried:
Added quotes to the "leadId" and "note" field in data - made no difference.
Added alert boxes to show the value of #Model.Id and txtNote.value before the AJAX call to verify they are correct - they are.
Put a breakpoint in the AddNoteAsync function in my controller - it's never hit
Hard coded the url field to /Leads/AddNoteAsync - made no difference
Since the controller function is never being hit I'm assuming something is wrong with the &.ajax part but I cannot figure out what.
Edit: The controller method:
[HttpPost]
[ValidateAntiForgeryToken]
public async Task<IActionResult> AddNoteAsync(int? leadId, string note)
{
ViewData["AddedNote"] = false;
if (leadId == null)
{
return RedirectToAction("Index", new { initials = User.Identity.Name });
}
var lead = await _context.Leads.FirstOrDefaultAsync(m => m.Id == leadId);
if (lead == null)
{
return RedirectToAction("Index", new { initials = User.Identity.Name });
}
var ownsLead = await LeadBelongsToCurrentUser(leadId.Value, User.Identity.Name);
if (!ownsLead)
{
return RedirectToAction("Index", new { initials = User.Identity.Name });
}
_context.LeadNotes.Add(new LeadNoteModel()
{
LeadId = leadId.Value,
Note = note,
NoteDate = DateTime.Now
});
await _context.SaveChangesAsync();
ViewData["AddedNote"] = true;
return Content("Success");
}
You should accept parameters as Model while making POST request(Recommended). Proposed Model will be -
public class NoteModel
{
public int? leadId { get; set; }
public string note { get; set; }
}
and Action can be -
public async Task<IActionResult> AddNoteAsync(NoteModel model)
{
}
Also Jquery can be -
<script type="text/javascript">
$(document).ready(function () {
$('#AddNote').click(function () {
$('#AddNote').addClass("disabled");
var txtNote = document.getElementById('note');
var result = document.getElementById('result');
var postData = { leadId: #Model.Id, note: txtNote.value };
result.innerText = "Adding note...";
$.ajax({
url: "#Url.Action("AddNoteAsync", "Leads")",
type: "POST",
data: JSON.stringify(postData),
async: true,
success: function (data) {
// removed
},
});
});
});
Fixed this. I was missing this from my AJAX request:
beforeSend: function (xhr) {
xhr.setRequestHeader("XSRF-TOKEN", $('input:hidden[name="f"]').val());
},
And this from my Startup.cs:
services.AddAntiforgery(options =>
{
options.FormFieldName = "f";
options.HeaderName = "XSRF-TOKEN";
});
I am new to jquery and I can't resolve the following problem : I want to pass an object to one of the controllers in my mvc application. Here is what I got so far:
function enterPressed() {
$(function () {
$('#textBox').keypress(function (e) {
var code = e.keyCode ? e.keyCode : e.which;
if (code == 13) {
doSomethingElse(textBox.value)
}
});
});
}
function doSomethingElse(p) {
$.ajax({
type: 'GET',
data: {string: p},
url: '"Control/AddControl/Index"',
success: function (data) { alert(p) },
error: function (errorData) { alert("fail") }
});
return true;
But every time when I press enter I end up with the fail. My controller is found in ~/Controllers/Control/AddControl. Do any of you see the problem ?
My C# code:
public class AddControlController : Controller
{
//
// GET: /AddControl/
public ActionResult Index(string control)
{
return RedirectToAction("ShowControl");
}
}
You should change value name to control, as action expected. Also you can use #Url.Action() helper for setting url param.
$.ajax({
type: 'GET',
data: { control : p},
url: '#Url.Action("Index","AddControl")',
success: function (data) { alert(p) },
error: function (errorData) { alert("fail") }
});
Finally, your action can't return redirect action with ajax response.
If you want to make redirect after successful response, you can make it in client side.
There are a few problems:
1-you are using a wrong url. The correct url is '/AddControl/Index'.
2-Your code in your controller won't work, since you are using ajax. You should return Json and handle the redirect in the client side.
3-You should allow GET through ajax:
public ActionResult Index()
{
return Json("Ok", JsonRequestBehavior.AllowGet);
}
You might want to just POST in stead of GET.
function doSomethingElse(p) {
$.post(
'#Url.Action("Index", "AddControl")',
{
control: p
},
function (data) {
alert(data);
}
);
}
You should decorate your controller action with the HttpPost attribute:
[HttpPost]
public ActionResult Index(string control)
{
return Json("I received this: " + control);
}
$(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);
}
});
});
I have an ajax POST like this
$(document).ready(function () {
var pcontent = document.body.innerHTML;
var url = new URI();
$.ajax({
url: url,
type: "POST",
data: { "pcontent": pcontent },
success: function (data) {
alert($(data).find(".right-panel").html());
},
complete: function () {
},
error: function (jqXHR, error, errorThrown) {
if (jqXHR.status) {
alert(jqXHR.responseText);
} else {
alert("Something went wrong");
}
}
});
return false;
});
I am little confused how i could retrieve data (pcontent) that i post here in my code behind.actually in a specific class file i need to implement this logic .
You have to create a controller action:
public class HomeController: {
// model
public class PDocument {
public string pcontent {get;set;}
}
[HttpPost]
public ActionResult SaveDocument(PDocument pcontent){
// do something
return new JsonResult() { Data = new { Success = true } };
}
}
JS:
$.ajax({
url: "Home/SaveDocument",
type: "POST",
data: { "pcontent": pcontent}
...});
Note:
You don't need to create a model on server if set
$.ajax({
url: "Home/SaveDocument",
type: "POST",
data: pcontent
});
// server side
public ActionResult SaveDocument(string pcontent){
// do some thing
}
For security reason, your html must be encoded before calling ajax
In case you new to mvc, then this is a good way to start: http://www.asp.net/mvc/tutorials/mvc-4/getting-started-with-aspnet-mvc4/adding-a-controller
i am trying to pass in a filename as a requestparameter into a controller, but it returns with an invalid request?
$(document).ready(function (event) {
$('#btnTask').click(function () {
$.ajax({
url: "/Home/Sometask/",
data: "c:\\somefile.txt",
async: false,
success: function (data) { alert(data); }
});
event.preventDefault;
});
});
public string Sometask(string id)
{
return "ready";
}
Use data: { filename: "c:\\somefile.txt" }
You have to give a variable name for the post data so your controller know how to map the value.
