I have the following AjaxOptions object:
AjaxOptions ajaxOpts = new AjaxOptions
{
HttpMethod = "Get",
InsertionMode = InsertionMode.Replace
};
In the view I have this form:
#using (Ajax.BeginForm("GetPeopleData", ajaxOpts))
{
<div>
<button type="submit">Submit</button>
</div>
}
This results in the following HTML:
<form action="/People/GetPeopleData" data-ajax="true" data-ajax-method="Get" id="form0" method="post">
<div>
<button type="submit">Submit</button>
</div>
</form>
When I submit the form I can see that a GET request is sent.
Why does the HTML have data-ajax-method="Get" and method="post"?
What is the purpose of the method="post"?
The #Ajax.BeginForm() helper utilize jQuery unobtrusive AJAX library. If you examine the helper return type, it returns System.Web.Mvc.Html.MvcForm, the same return type as #Html.BeginForm() which creates <form> tag:
public static MvcForm BeginForm(
this AjaxHelper ajaxHelper,
AjaxOptions ajaxOptions
)
Since all of its overloads don't have parameter which specify HTTP request in System.Web.Mvc.FormMethod enumeration, it uses default POST request like #Html.BeginForm() has, hence it also writes method="post" for default form method if unobstrusive AJAX script is disabled in client side.
The purpose of data-ajax-method attribute is to override default submit request behavior when unobtrusive AJAX enabled because its value set by AjaxOptions.HttpMethod property, and checked by asyncRequest() method inside unobtrusive AJAX library (see complete version of the script here):
function asyncRequest(element, options) {
var confirm, loading, method, duration;
confirm = element.getAttribute("data-ajax-confirm");
if (confirm && !window.confirm(confirm)) {
return;
}
loading = $(element.getAttribute("data-ajax-loading"));
duration = parseInt(element.getAttribute("data-ajax-loading-duration"), 10) || 0;
$.extend(options, {
type: element.getAttribute("data-ajax-method") || undefined, // here AJAX method is checked (GET or POST)
url: element.getAttribute("data-ajax-url") || undefined,
cache: (element.getAttribute("data-ajax-cache") || "").toLowerCase() === "true",
beforeSend: function (xhr) {
var result;
asyncOnBeforeSend(xhr, method);
result = getFunction(element.getAttribute("data-ajax-begin"), ["xhr"]).apply(element, arguments);
if (result !== false) {
loading.show(duration);
}
return result;
},
complete: function () {
loading.hide(duration);
getFunction(element.getAttribute("data-ajax-complete"), ["xhr", "status"]).apply(element, arguments);
},
success: function (data, status, xhr) {
asyncOnSuccess(element, data, xhr.getResponseHeader("Content-Type") || "text/html");
getFunction(element.getAttribute("data-ajax-success"), ["data", "status", "xhr"]).apply(element, arguments);
},
error: function () {
getFunction(element.getAttribute("data-ajax-failure"), ["xhr", "status", "error"]).apply(element, arguments);
}
});
Note: You can see list of attributes which corresponds to each properties of AjaxOptions in this reference.
I have html like this:
HTML
<div class="col-md-3 col-sm-12">
<div>
<p>Región</p>
<select id="lstRegion" class="form-control agenda_space" aria-hidden="true"></select>
</div>
<div>
<p>Solicitud</p>
<select id="lstSolicitud" class="form-control agenda_space" aria-hidden="true"> </select>
</div>
<br/>
<div>
Actualizar Filtro
<br/>
</div>
JS:
$("#lstRegion")
.getJSONCatalog({
onSuccess: function (response) {
console.log(response);
},
url: '/Agenda/GetRegion',
valueProperty: "ID",
textProperty: "valor"
});
//Load solicitud dropdown
$("#lstSolicitud")
.getJSONCatalog({
url: '/Agenda/GetSolicitud',
valueProperty: "ID",
textProperty: "solicitud"
});
Controller:
public ActionResult GetRegion()
{
try
{
var listaRegistros = db.CatalogoRegistros.Where(x => x.CatalogosCodigo == "REGI").Select(x => new
{
x.ID
,
valor = x.Valor
});
return Json(listaRegistros, JsonRequestBehavior.AllowGet);
}
catch (Exception ex)
{
throw ex;
}
}
public ActionResult GetSolicitud()
{
try
{
var listasolicitud = db.Solicitudes.Select(x => new { x.ID, solicitud = "Folio: " + x.ID });
return Json(listasolicitud, JsonRequestBehavior.AllowGet);
}
catch (Exception ex)
{
throw ex;
}
}
They work great I get my dropdwon lists very well, but now I want to do a GET action with selected values of each dropdown when my Actualizar Filtro it´s clicked.
But I´m really new in asp.net and I don´t know what I need to do to get selected values and send to controller.
As googling it I found I need to do method into my controller to get values so:
Controller will be:
public ActionResult GetTareas(string lstRegionValue, string lstsolicitudValue)
{
}
But I don´t know how to send them via JS, how can I do that to receive selected parameters into my controller? Regards
UPDATE
I try it using Ajax like:
$.ajax({
type: 'GET',
url: '#Url.Action("Agenda", "GetTareas")',
data: { region: $('#lstRegion option:selected').html(), solicitud: $('#lstSolicitud option:selected').html() }, // pass the value to the id parameter
dataType: 'json',
success: function (data) {
console.log(data);
}});
But how can I trigger that function when event_add is clicked?
To run your updated ajax code on click, add #event_add click event handler and run your code inside it.
$('#event_add').click(function(e){
e.preventDefault(); //suppress default behavior
$.ajax({
type: 'GET',
url: '#Url.Action("Agenda", "GetTareas")', // don't hard code your urls
data: { region: $('#lstRegion option:selected').html(), solicitud:
$('#lstSolicitud option:selected').html() }, // pass the value to the id parameter
dataType: 'json', // your returning a view, not json
success: function (data) {
console.log(data);
}});
});
Hi Try the below updated code:
$('#event_add').click(function(e){
var regionval = $('#lstRegion option:selected').html(),
var solicval = $('#lstSolicitud option:selected').html(),
$.ajax({
type: 'GET',
url: '#Url.Action("Agenda", "GetTareas", new { lstRegionValue = regionval, lstsolicitudValue =solicval})',
});
});
Note : I didnt test the code, but hope that it should work for you
Controller code:
public ActionResult GetTareas(string lstRegionValue, string lstsolicitudValue)
{
}
Hope it helps , thanks
I am having trouble with the AntiForgeryToken with ajax. I'm using ASP.NET MVC 3. I tried the solution in jQuery Ajax calls and the Html.AntiForgeryToken(). Using that solution, the token is now being passed:
var data = { ... } // with token, key is '__RequestVerificationToken'
$.ajax({
type: "POST",
data: data,
datatype: "json",
traditional: true,
contentType: "application/json; charset=utf-8",
url: myURL,
success: function (response) {
...
},
error: function (response) {
...
}
});
When I remove the [ValidateAntiForgeryToken] attribute just to see if the data (with the token) is being passed as parameters to the controller, I can see that they are being passed. But for some reason, the A required anti-forgery token was not supplied or was invalid. message still pops up when I put the attribute back.
Any ideas?
EDIT
The antiforgerytoken is being generated inside a form, but I'm not using a submit action to submit it. Instead, I'm just getting the token's value using jquery and then trying to ajax post that.
Here is the form that contains the token, and is located at the top master page:
<form id="__AjaxAntiForgeryForm" action="#" method="post">
#Html.AntiForgeryToken()
</form>
You have incorrectly specified the contentType to application/json.
Here's an example of how this might work.
Controller:
public class HomeController : Controller
{
public ActionResult Index()
{
return View();
}
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Index(string someValue)
{
return Json(new { someValue = someValue });
}
}
View:
#using (Html.BeginForm(null, null, FormMethod.Post, new { id = "__AjaxAntiForgeryForm" }))
{
#Html.AntiForgeryToken()
}
<div id="myDiv" data-url="#Url.Action("Index", "Home")">
Click me to send an AJAX request to a controller action
decorated with the [ValidateAntiForgeryToken] attribute
</div>
<script type="text/javascript">
$('#myDiv').submit(function () {
var form = $('#__AjaxAntiForgeryForm');
var token = $('input[name="__RequestVerificationToken"]', form).val();
$.ajax({
url: $(this).data('url'),
type: 'POST',
data: {
__RequestVerificationToken: token,
someValue: 'some value'
},
success: function (result) {
alert(result.someValue);
}
});
return false;
});
</script>
Another (less javascriptish) approach, that I did, goes something like this:
First, an Html helper
public static MvcHtmlString AntiForgeryTokenForAjaxPost(this HtmlHelper helper)
{
var antiForgeryInputTag = helper.AntiForgeryToken().ToString();
// Above gets the following: <input name="__RequestVerificationToken" type="hidden" value="PnQE7R0MIBBAzC7SqtVvwrJpGbRvPgzWHo5dSyoSaZoabRjf9pCyzjujYBU_qKDJmwIOiPRDwBV1TNVdXFVgzAvN9_l2yt9-nf4Owif0qIDz7WRAmydVPIm6_pmJAI--wvvFQO7g0VvoFArFtAR2v6Ch1wmXCZ89v0-lNOGZLZc1" />
var removedStart = antiForgeryInputTag.Replace(#"<input name=""__RequestVerificationToken"" type=""hidden"" value=""", "");
var tokenValue = removedStart.Replace(#""" />", "");
if (antiForgeryInputTag == removedStart || removedStart == tokenValue)
throw new InvalidOperationException("Oops! The Html.AntiForgeryToken() method seems to return something I did not expect.");
return new MvcHtmlString(string.Format(#"{0}:""{1}""", "__RequestVerificationToken", tokenValue));
}
that will return a string
__RequestVerificationToken:"P5g2D8vRyE3aBn7qQKfVVVAsQc853s-naENvpUAPZLipuw0pa_ffBf9cINzFgIRPwsf7Ykjt46ttJy5ox5r3mzpqvmgNYdnKc1125jphQV0NnM5nGFtcXXqoY3RpusTH_WcHPzH4S4l1PmB8Uu7ubZBftqFdxCLC5n-xT0fHcAY1"
so we can use it like this
$(function () {
$("#submit-list").click(function () {
$.ajax({
url: '#Url.Action("SortDataSourceLibraries")',
data: { items: $(".sortable").sortable('toArray'), #Html.AntiForgeryTokenForAjaxPost() },
type: 'post',
traditional: true
});
});
});
And it seems to work!
it is so simple! when you use #Html.AntiForgeryToken() in your html code it means that server has signed this page and each request that is sent to server from this particular page has a sign that is prevented to send a fake request by hackers. so for this page to be authenticated by the server you should go through two steps:
1.send a parameter named __RequestVerificationToken and to gets its value use codes below:
<script type="text/javascript">
function gettoken() {
var token = '#Html.AntiForgeryToken()';
token = $(token).val();
return token;
}
</script>
for example take an ajax call
$.ajax({
type: "POST",
url: "/Account/Login",
data: {
__RequestVerificationToken: gettoken(),
uname: uname,
pass: pass
},
dataType: 'json',
contentType: 'application/x-www-form-urlencoded; charset=utf-8',
success: successFu,
});
and step 2 just decorate your action method by [ValidateAntiForgeryToken]
In Asp.Net Core you can request the token directly, as documented:
#inject Microsoft.AspNetCore.Antiforgery.IAntiforgery Xsrf
#functions{
public string GetAntiXsrfRequestToken()
{
return Xsrf.GetAndStoreTokens(Context).RequestToken;
}
}
And use it in javascript:
function DoSomething(id) {
$.post("/something/todo/"+id,
{ "__RequestVerificationToken": '#GetAntiXsrfRequestToken()' });
}
You can add the recommended global filter, as documented:
services.AddMvc(options =>
{
options.Filters.Add(new AutoValidateAntiforgeryTokenAttribute());
})
Update
The above solution works in scripts that are part of the .cshtml. If this is not the case then you can't use this directly. My solution was to use a hidden field to store the value first.
My workaround, still using GetAntiXsrfRequestToken:
When there is no form:
<input type="hidden" id="RequestVerificationToken" value="#GetAntiXsrfRequestToken()">
The name attribute can be omitted since I use the id attribute.
Each form includes this token. So instead of adding yet another copy of the same token in a hidden field, you can also search for an existing field by name. Please note: there can be multiple forms inside a document, so name is in that case not unique. Unlike an id attribute that should be unique.
In the script, find by id:
function DoSomething(id) {
$.post("/something/todo/"+id,
{ "__RequestVerificationToken": $('#RequestVerificationToken').val() });
}
An alternative, without having to reference the token, is to submit the form with script.
Sample form:
<form id="my_form" action="/something/todo/create" method="post">
</form>
The token is automatically added to the form as a hidden field:
<form id="my_form" action="/something/todo/create" method="post">
<input name="__RequestVerificationToken" type="hidden" value="Cf..." /></form>
And submit in the script:
function DoSomething() {
$('#my_form').submit();
}
Or using a post method:
function DoSomething() {
var form = $('#my_form');
$.post("/something/todo/create", form.serialize());
}
In Asp.Net MVC when you use #Html.AntiForgeryToken() Razor creates a hidden input field with name __RequestVerificationToken to store tokens. If you want to write an AJAX implementation you have to fetch this token yourself and pass it as a parameter to the server so it can be validated.
Step 1: Get the token
var token = $('input[name="`__RequestVerificationToken`"]').val();
Step 2: Pass the token in the AJAX call
function registerStudent() {
var student = {
"FirstName": $('#fName').val(),
"LastName": $('#lName').val(),
"Email": $('#email').val(),
"Phone": $('#phone').val(),
};
$.ajax({
url: '/Student/RegisterStudent',
type: 'POST',
data: {
__RequestVerificationToken:token,
student: student,
},
dataType: 'JSON',
contentType:'application/x-www-form-urlencoded; charset=utf-8',
success: function (response) {
if (response.result == "Success") {
alert('Student Registered Succesfully!')
}
},
error: function (x,h,r) {
alert('Something went wrong')
}
})
};
Note: The content type should be 'application/x-www-form-urlencoded; charset=utf-8'
I have uploaded the project on Github; you can download and try it.
https://github.com/lambda2016/AjaxValidateAntiForgeryToken
function DeletePersonel(id) {
var data = new FormData();
data.append("__RequestVerificationToken", "#HtmlHelper.GetAntiForgeryToken()");
$.ajax({
type: 'POST',
url: '/Personel/Delete/' + id,
data: data,
cache: false,
processData: false,
contentType: false,
success: function (result) {
}
});
}
public static class HtmlHelper
{
public static string GetAntiForgeryToken()
{
System.Text.RegularExpressions.Match value = System.Text.RegularExpressions.Regex.Match(System.Web.Helpers.AntiForgery.GetHtml().ToString(), "(?:value=\")(.*)(?:\")");
if (value.Success)
{
return value.Groups[1].Value;
}
return "";
}
}
In Account controller:
// POST: /Account/SendVerificationCodeSMS
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public JsonResult SendVerificationCodeSMS(string PhoneNumber)
{
return Json(PhoneNumber);
}
In View:
$.ajax(
{
url: "/Account/SendVerificationCodeSMS",
method: "POST",
contentType: 'application/x-www-form-urlencoded; charset=utf-8',
dataType: "json",
data: {
PhoneNumber: $('[name="PhoneNumber"]').val(),
__RequestVerificationToken: $('[name="__RequestVerificationToken"]').val()
},
success: function (data, textStatus, jqXHR) {
if (textStatus == "success") {
alert(data);
// Do something on page
}
else {
// Do something on page
}
},
error: function (jqXHR, textStatus, errorThrown) {
console.log(textStatus);
console.log(jqXHR.status);
console.log(jqXHR.statusText);
console.log(jqXHR.responseText);
}
});
It is important to set contentType to 'application/x-www-form-urlencoded; charset=utf-8' or just omit contentTypefrom the object ...
I know this is an old question. But I will add my answer anyway, might help someone like me.
If you dont want to process the result from the controller's post action, like calling the LoggOff method of Accounts controller, you could do as the following version of #DarinDimitrov 's answer:
#using (Html.BeginForm("LoggOff", "Accounts", FormMethod.Post, new { id = "__AjaxAntiForgeryForm" }))
{
#Html.AntiForgeryToken()
}
<!-- this could be a button -->
Submit
<script type="text/javascript">
$('#ajaxSubmit').click(function () {
$('#__AjaxAntiForgeryForm').submit();
return false;
});
</script>
For me the solution was to send the token as a header instead of as a data in the ajax call:
$.ajax({
type: "POST",
url: destinationUrl,
data: someData,
headers:{
"RequestVerificationToken": token
},
dataType: "json",
success: function (response) {
successCallback(response);
},
error: function (xhr, status, error) {
// handle failure
}
});
The token won't work if it was supplied by a different controller. E.g. it won't work if the view was returned by the Accounts controller, but you POST to the Clients controller.
I tried a lot of workarrounds and non of them worked for me. The exception was "The required anti-forgery form field "__RequestVerificationToken" .
What helped me out was to switch form .ajax to .post:
$.post(
url,
$(formId).serialize(),
function (data) {
$(formId).html(data);
});
Feel free to use the function below:
function AjaxPostWithAntiForgeryToken(destinationUrl, successCallback) {
var token = $('input[name="__RequestVerificationToken"]').val();
var headers = {};
headers["__RequestVerificationToken"] = token;
$.ajax({
type: "POST",
url: destinationUrl,
data: { __RequestVerificationToken: token }, // Your other data will go here
dataType: "json",
success: function (response) {
successCallback(response);
},
error: function (xhr, status, error) {
// handle failure
}
});
}
Create a method that will responsible to add token
var addAntiForgeryToken = function (data) {
data.__RequestVerificationToken = $("[name='__RequestVerificationToken']").val();
return data;
};
Now use this method while passing data/parameters to Action like below
var Query = $("#Query").val();
$.ajax({
url: '#Url.Action("GetData", "DataCheck")',
type: "POST",
data: addAntiForgeryToken({ Query: Query }),
dataType: 'JSON',
success: function (data) {
if (data.message == "Success") {
$('#itemtable').html(data.List);
return false;
}
},
error: function (xhr) {
$.notify({
message: 'Error',
status: 'danger',
pos: 'bottom-right'
});
}
});
Here my Action have a single parameter of string type
[HttpPost]
[ValidateAntiForgeryToken]
public JsonResult GetData( string Query)
{
#using (Ajax.BeginForm("SendInvitation", "Profile",
new AjaxOptions { HttpMethod = "POST", OnSuccess = "SendInvitationFn" },
new { #class = "form-horizontal", id = "invitation-form" }))
{
#Html.AntiForgeryToken()
<span class="red" id="invitation-result">#Html.ValidationSummary()</span>
<div class="modal-body">
<div class="row-fluid marg-b-15">
<label class="block">
</label>
<input type="text" id="EmailTo" name="EmailTo" placeholder="forExample#gmail.com" value="" />
</div>
</div>
<div class="modal-footer right">
<div class="row-fluid">
<button type="submit" class="btn btn-changepass-new">send</button>
</div>
</div>
}
I'm struggling to return a view or partial view with Ajax. Whenever I change the return type to something that isn't JSon the ajax command never succeeds. I need to return a partial view because I want to return a lot of data back.
This is my current code:
(Controller)
[HttpPost]
public ActionResult AjaxTestController(string Input)
{
string Results = Input + " -- TestTestTest";
return PartialView("Test", Results);
//return new JsonResult() { };
}
(View)
function AjaxTest() {
alert("test");
$.ajax({
type: "POST",
url: "Home/AjaxTestController",
data: "Input=Test11111",
success: function () {
alert("Success!");
}
});
Thanks!
You can use the $.post command for that:
function AjaxTest() {
alert("test");
$.post({
url: "Home/AjaxTestController",
data: "Input=Test11111",
success: function (response) {
alert(response);
}
});
try the following:
$(function () {
$('#submit').live('click', function () {
AjaxTest();
});
});
function AjaxTest() {
$.ajax({
type: "POST",
url: '#Url.Action("AjaxTestController", "Home")',
data: { Input: "Test - " + new Date() },
success: function (data) {
$('#partialResult').html(data);
},
error: function (xhr, err) {
alert(xhr.responseText);
}
});
};
inside your view and ensure that you have your target div set up for the partial to be populated into:
<div id="partialResult"></div>
also, for the example above, I added a button to the view to initiate the ajax (purely for testing):
<input type="button" value="Submit" id="submit" />
your 'partialview' should look something like this:
#model string
<h2>
Partial Test</h2>
<p>
#Model
</p>
no other changes are required to the existing action for this to now function as required.
[UPDATE] - I changed the AjaxTest() method to include the error event (the result of which is captured in an alert). hopefully, this may help further.
partial View is different than view you have to specify the whole path to the partial view or have it in share folder. otherwise is going to return not found and never success. any way this always work for me, try
partialView("~/Views/ControllerView/Test.cshtml")
Is it possible to do something like this using asp.net mvc 3
#using(Ajax.BeginForm("SomeAction","MyController",new AjaxOptions {OnSuccess="function(content){ alert(content); }"}))
{
#Html.Partial("Recorder")
<input type="submit" />
}
I am using Jquery for ajax operations and not MSAjax.
Thanks
You can just use a normal Html.BeginForm, assign a id to the form, and use the jquery ajax to handle submission:
#using (Html.BeginForm("Index", "Home", FormMethod.Post, new { id = "formData" }))
The submission function:
// Function to submit form data
function submitForm() {
var frm = $('#formData');
$.ajax({
url: '/Home/Create',
type: 'POST',
data: frm.serialize(),
beforeSend: function () {
},
onsuccess: function (){},
success: function (result) { },
error: function () { }
});
}
Hope this what you mean/need :)
