$http({
method: 'GET',
dataType: 'json',
url: 'Calendar/GetDate',
params: { calenderId: $scope.CalendarId, fyYear: new Date(viewValue).toUTCString()
}
}).success(function (result) {
alert(result);
});
Below value getting returns, and its not calling the controller method
[UMAuthorize]
public ActionResult GetDate(string calenderId, DateTime fyYear)
{
.......
.....
return Json(new { startDate }, JsonRequestBehavior.AllowGet);
}
You are posting data to controller so I guess you should put the attribute HttpPost as shown below :-
[UMAuthorize]
[HttpPost]
public ActionResult GetDate(string calenderId, DateTime fyYear)
{
.......
.....
return Json(new { startDate }, JsonRequestBehavior.AllowGet);
}
and from you are calling controller make it a Post method instead of Get as shown below :-
$http({
method: 'POST',
dataType: 'json',
url: 'Calendar/GetDate',
params: { calenderId: $scope.CalendarId, fyYear: new Date(viewValue)
}
}).success(function (result) {
alert(result);
});
and ur fyYear object is DateTime in controller but you are converting it into string and then sending so its not matching the parameters of controller
I susupect the the url passed is wrong, use Url.Action() helper for generating correct url:
change:
url: 'Calendar/GetDate'
to:
url: '#Url.Action("GetDate","Calendar")'

In MVC, I have written an action in the controller for getting values. The action is as follows..
public void poolshapepdf(List<String> values)
{
...
}
To pass the parameter values to the controller action i pass the values from javascript..
the code is the below,
$.ajax({
type: 'POST',
url: rootDir + "IngroundCalculation/poolshapepdf",
data: { values: collectionPSElmt },
traditional: true,
});
Here collectionPSElmt is an array.
collectionPSElmt[index] = poolshapeValue[index] + "-" + psFeet[index] + "-" + psInch[index];
Here the issue is the controller action cannot be called from the javascript $.Ajax(..).
How do I fix this issue?
You calling the controller by POST and JSON data:
[HttpPost]
public JsonResult poolshapepdf(DataClass[] items)
{
}
Now, make a proper call to your url.
specify the data type as json and always go for success function.
using that you can easily crack the report.
$.ajax({
url: '#Url.Action("poolshapepdf", "IngroundCalculation")',
type: "POST",
dataType: 'json',
data: collectionPSElmt ,
contentType: "application/json; charset=utf-8",
success: function (result) {
alert("Working..");
}
});
And at Controller Side,
[HttpPost]
public JsonResult poolshapepdf(DataClass[] items)
{
// Your Code here....
}
I have this link on my page:
#Html.ActionLink("Like", "Like", "Like", new {likeId = i.ItemId}, new {id = #i.ItemId, #class = "likeButton"})
This is my ajax call:
$(document).on("click", ".likeButton", function (event) {
var itemId = event.target.id;
$.ajax({
url: this.href,
type: 'POST',
data: { item: itemId },
context: this,
success: function (result) {
...
return false;
});
And it works when action metohd is like:
public ActionResult Like(int itemId)
...
But if I decorate method with [HttpPost] It doesn't work.
Can this be achieved?
Also what security issue can be if I don't add [HttpPost]?
Try this:
$(document).on("click", ".likeButton", function (event) {
$.ajax({
url: this.href,
type: 'POST',
context: this,
success: function (result) {
...
return false;
});
You are passing item.Id twice, first in url and second in body. when using post method, you can still pass parameters through url. passing parameters with body is good when you want to hide these parameters.
And one more thing, you can use Ajax.ActionLink in this case (because it is created for this kind of cases)
And you have mistake:
data: { item: itemId }
Should be:
data: { itemId: itemId },
hi guys i'm posting some data to controller using jquery ajax, but i am getting null values in my controller,
jQuery code is:
$('#registerCompOff').click(function() {
var compOff = [];
$('div').each(function() {
var curRow = {};
curRow.Description = $(this).find('.reason').val();
curRow.CompOffDate = $(this).find('.datefieldWithWeekends').val();
if (curRow.Description != null && curRow.CompOffDate != null) {
compOff.push(curRow);
}
});
$.ajax({
type: 'POST',
url: this.href,
dataType: 'json',
data: compOff
});
return $('form').valid();
});
compOff is not null I have checked that...
controller is:
[HttpPost]
public ActionResult RegisterCompOff(RegisterCompOff[] registerCompOff)
{
//return View();
}
can you tell me where i'm going wrong?
Given your original code, change in $.ajax -> data: JSON.stringify(compOff) then add contentType: "application/json; charset=utf-8" and finally change parameter name of controller's action to public ActionResult RegisterCompOff(RegisterCompOff[] compOff). Model binding should kick off then. It did for me.
Edited:
try this :
$.ajax({
type: 'POST',
url: this.href,
dataType: 'json',
traditional: true,
data:
{
CompOffList: compOff
}
});
and change your controller like this :
[HttpPost]
public ActionResult RegisterCompOff(List<RegisterCompOff> CompOffList)
{
//return View();
}
hope this helps
Your r passing javascript object as data wherease jquery ajax method expects a key/value pair list.
Try this
data:{Description:compOff.Description, CompOffDate:compOff.CompOffDate}
I am sending json data to my controller action via jquery ajax post. The IEnumerable in my action is alway null.
Is my json wrong or why does the model binder not convert the json to the IEnumerable ?
public ActionResult Update(IEnumerable<Teststep> teststeps)
{
//
}
$.ajax({
url: '#Url.Action("Update", "Teststep")',
type: 'POST',
data: [{ "errortext": "oh something bad happended.", "unitid": "10" }, { "errortext": "you got it man.", "unitid": "20"}],
success: function (response) {
debugger;
if (response.success) {
dlg.dialog("close");
// Update UI
}
else {
// Reload the dialog with the form to show model/validation errors
dlg.html(response);
}
}
});
public class Teststep
{
[HiddenInput(DisplayValue = false)]
public int UnitId { get; set; }
public string ErrorText { get; set; }
// some other props removed for readability
}
In order to get collections (arrays, ienumerables, etc) to pass correctly through the modelbinder to the action method, I've always had to set the traditional: true option on the ajax call:
$.ajax({
url: '#Url.Action("Update", "Teststep")',
type: 'POST',
traditional: true,
...
Now it works! I get 1 item in the IEnumerable. The problem was the messed up json ;-)
var data = { teststeps: [{ ErrorText: 'bla', UnitId: 10}] };
$.ajax({
url: '#Url.Action("Update", "Teststep")',
type: 'POST',
data: JSON.stringify(data),
dataType: 'json',
contentType: 'application/json'
});
[HttpPost]
public ActionResult Update(IEnumerable<Teststep> teststeps)
{
}
I use $.ajax() to poll an action method every 5 seconds as follows:
$.ajax({
type: 'GET', url: '/MyController/IsReady/1',
dataType: 'json', success: function (xhr_data) {
if (xhr_data.active == 'pending') {
setTimeout(function () { ajaxRequest(); }, 5000);
}
}
});
and the ActionResult action:
public ActionResult IsReady(int id)
{
if(true)
{
return RedirectToAction("AnotherAction");
}
return Json("pending");
}
I had to change the action return type to ActionResult in order to use RedirectToAction (originally it was JsonResult and I was returning Json(new { active = 'active' };), but it looks to have trouble redirecting and rendering the new View from within the $.ajax() success callback. I need to redirect to "AnotherAction" from within this polling ajax postback. Firebug's response is the View from "AnotherAction", but it's not rendering.
You need to consume the result of your ajax request and use that to run javascript to manually update window.location yourself. For example, something like:
// Your ajax callback:
function(result) {
if (result.redirectUrl != null) {
window.location = result.redirectUrl;
}
}
Where "result" is the argument passed to you by jQuery's ajax method after completion of the ajax request. (And to generate the URL itself, use UrlHelper.GenerateUrl, which is an MVC helper that creates URLs based off of actions/controllers/etc.)
I know this is a super old article but after scouring the web this was still the top answer on Google, and I ended up using a different solution. If you want to use a pure RedirectToAction this works as well. The RedirectToAction response contains the complete markup for the view.
C#:
return RedirectToAction("Action", "Controller", new { myRouteValue = foo});
JS:
$.ajax({
type: "POST",
url: "./PostController/PostAction",
data: data,
contentType: "application/json; charset=utf-8",
dataType: "json",
complete: function (result) {
if (result.responseText) {
$('body').html(result.responseText);
}
}
});
C# worked well
I just changed the JS because responseText was not working for me:
$.ajax({
type: "POST",
url: posturl,
contentType: false,
processData: false,
async: false,
data: requestjson,
success: function(result) {
if (result) {
$('body').html(result);
}
},
error: function (xhr, status, p3, p4){
var err = "Error " + " " + status + " " + p3 + " " + p4;
if (xhr.responseText && xhr.responseText[0] == "{")
err = JSON.parse(xhr.responseText).Message;
console.log(err);
}
});
You could use the Html.RenderAction helper in a View:
public ActionResult IsReady(int id)
{
if(true)
{
ViewBag.Action = "AnotherAction";
return PartialView("_AjaxRedirect");
}
return Json("pending");
}
And in the "_AjaxRedirect" partial view:
#{
string action = ViewBag.ActionName;
Html.RenderAction(action);
}
