I have an old asp.net mvc project using JS. I need to add Cross-Site Request Forgery protection, but I don't know, how to implement it in my case.
Could somebody help me with this, please?
chtml-view:
#model WebGridResults<IndexingCollectionModel>
#{
ViewBag.Title = "Manage Collections";
Layout = "~/_Indexing.cshtml";
}
#section grid_options
{
<div class="km-grid-option-padding">
<ul class="inline pull-right">
<li>
<a id="kmid_removeSelected"
class="km-grid-option remove"
href="#Url.Action("DeleteSelected", "Indexing", new { Area = "Admin" })"
data-target="km_grid_body"
data-redirect="#Url.Action("ManageCollections", "Indexing", new { Area = "Admin" })"
data-actiontype="submit_selected"
data-message="Do you want to continue?"><i class="icon-remove"></i> Remove Selected</a>
</li>
</ul>
</div>
}
JS-part:
$("[data-actiontype='submit_selected']").bind("click",
function () {
var $this = $(this);
var message = $this.data("message");
KM.Ajax.ShowConfirmation({ title: "Warning", message: message }, function () {
var url = $this.attr("href");
var redirect = $this.data("redirect");
var targetId = $this.data("target");
var selected = [];
var SelectedItemsIds = GetSelectedItemsIds();
$.each(SelectedItemsIds, function (Key, Item) {
selected.push({ name: "selected", value: Item });
});
//THIS PART WAS ADDED BY ME *********
var token = $("input[name='__RequestVerificationToken']").val();
if(token !== undefined && token !== "")
selected.push({name: "__RequestVerificationToken", value: token});
//*****************
$.ajax({
type: "POST",
url: url,
data: selected,
success: function (result) {
if (typeof (result) == "object") {
var json = result || {};
if (json.Success) {
var $target = $("#" + targetId);
if( settings.fullPageLoad === true )
{
location.reload();
}
else
{
$target.load( redirect, function()
{
if( settings.reloadCallback )
{
settings.reloadCallback();
}
} );
}
}
}
},
dataType: "json",
traditional: true
});
});
return false;
});
Controller:
[HttpPost]
[ValidateAntiForgeryToken()]
public ActionResult DeleteSelected(Guid[] selected)
{
try
{
_presenter.Delete(selected);
return Json(new { Success = true });
}
catch (Exception ex)
{
ModelState.AddModelError(ErrorRemoveSelected, ex.Message);
var errors = ModelState.ParseErrors();
return Json(new { Success = false, Errors = errors });
}
}
I've tried to add to request data (it is my part of code) in JS-function:
var token = $("input[name='__RequestVerificationToken']").val();
if(token !== undefined && token !== "")
selected.push({name: "__RequestVerificationToken", value: token});
Also I've added [ValidateAntiForgeryToken()] to controller method.
And it works, but only one time. When I try to perform the same action on the same page - it doesn't work.
What am I doing wrong?
Thank you in advanced!

I am looking to show a modal, I have my Modals as partial classes, so if you select the class .js-verify-songs it loads up the partial _VerifySong . If however there is an error, it should load up the error partial _ErrorMessage. And finally if you select .js-reject-song it should load _RejectSong partial.
Any idea how I would do this, please?

I am unsure though how I would show a list of error in my error partial view. Also how do you load a partial view with Ajax?
Currently you click verify and it loads the spinner, but I would like to load a partial view which is a modal. I’ve used partials because it’s what was decided. I’m just unsure how to get them to load using Ajax.
I am trying to check if an email address exists in the database. I have an external JavaScript file that I am using to call my jQuery (to keep my view clean). Perhaps it is because I am running with SSL enabled? (I am using https)
Function in external js file:
function checkemail() {
var email = $("#email").val();
$.ajax({
url: "/Account/CheckEmailExists/",
data: JSON.stringify({ p: email }),
type: "POST",
contentType: "application/json; charset=utf-8",
success: function (data) {
alert(data)
}
});
}
Action in Controller:
public ActionResult CheckEmailExists(string p)
{
bool bEmailExists = false;
using (RBotEntities EF = new RBotEntities())
{
var query = (from U in EF.AspNetUsers
where U.Email == p
select U).FirstOrDefault();
if(query.Email != null)
{
bEmailExists = true;
}
else
{
bEmailExists = false;
}
}
return Json(bEmailExists, JsonRequestBehavior.AllowGet);
}
I seem to be getting an error stating the following:
XML Parsing Error: no root element found Location:
https://localhost:44347/Account/CheckEmailExists/ Line Number 1,
Column 1:
My understanding would be that this ActionResult does not exist. But it does ?
Am I doing something wrong, or is there a reason why an ActionResult can not be called via an external JavaScript file ?
Try this
In Controller
[httppost]
public ActionResult CheckEma.........
In JS
function checkemail() {
var email = $("#email").val();
$.ajax({
url: "/Account/CheckEmailExists/",
data: { p: email },
type: "POST",
success: function (data) {
alert(data)
}
});
}
No need for Json.Stringify and ContentType here
function checkemail() {
var email = $("#email").val();
$.ajax({
url: "/Account/CheckEmailExists",
data: { p: email },
type: "POST",
success: function (data) {
alert(data)
}
});
}
So I found out what was causing the issue...
Above my Action result, I needed to add [AllowAnonymous] data annotation and then it reached my ActionResult! I would prefer to not allow anonymous, but it works and I wanted to share this in case it helps someone else. Below is my code:
ActionResult:
[AllowAnonymous]
public ActionResult CheckEmailExists(string p)
{
bool bEmailExists = false;
using (RBotEntities EF = new RBotEntities())
{
var query = (from U in EF.AspNetUsers
where U.Email == p
select U).FirstOrDefault();
if (query.Email != null)
{
bEmailExists = true;
}
else
{
bEmailExists = false;
}
}
return Json(bEmailExists, JsonRequestBehavior.AllowGet);
}
JavaScript function in JavaScript File:
function checkemail() {
var email = $("#email").val();
var bReturnedValue = false;
$.ajax({
url: "/Account/CheckEmailExists/",
data: { p: email },
async: false,
success: function (data) {
if(data)
{
bReturnedValue = true;
}
else
{
bReturnedValue = false;
}
}
});
return bReturnedValue;
}
And this is how I initiated it(I am doing a popover to specify that the email exists):
$("#createacc_next").click(function () {
var bEmailExists = false;
bEmailExists = checkemail();
if (bEmailExists) {
$("#email").attr("disabled", false).css("border-color", "red");
$('#email').popover({ title: 'Attention', content: 'Email address already exists', placement: 'top', trigger: 'focus' });
Email_Validation_Passed = false;
}
})
I have a MVC view that by clicking on submit button it post Data using Ajax to the Controller. The controller return json result that is messages and I show them on the View. The problem is when I click on Submit button it working fine but when I push Enter after show the Thank you page again it post to the controller method and show a page with json Data as bellow: (I need to make the Enter work as pushing Submit as well)
{"status":"success","message":""}
This is my View:
#using (Html.BeginForm("forgotPassword", "Home", FormMethod.Post))
{
#Html.AntiForgeryToken()
<div>
<div>Email Address</div>
<div><input type="email" name="email" placeholder="example#email.com" id="email" class="forgot-password-textbox"></div>
<div><label id="Message" class="forgot-password-error-message"></label></div>
<div><input type="button" value="Submit" id="btn-reset-password" onclick="resetPasswordHandler()" class="orange-button forgot-password-button"></div>
</div>
}
This is my Controller Method:
[HttpPost]
[Route("forgotPassword")]
public async Task<JsonResult> ForgotPassword(ForgotPasswordRequest forgotPasswordRequest)
{
...
try
{
if (ModelState.IsValid)
{
if (!string.IsNullOrEmpty(forgotPasswordRequest.Email))
{
users = await authenticationService.GetUserByEmailAsync(forgotPasswordRequest.Email);
if (users.Any())
{
if(users.FirstOrDefault().StatusId == 2)
{
return Json(new { status = "error", message = Constants.MessageStrings.ForgotPasswordDisabledUser });
}
//New User without creating password
if (string.IsNullOrEmpty(users.FirstOrDefault().PasswordHash))
{
return Json(new { status = "error", message = Constants.MessageStrings.ForgotPasswordDisabledUser });
}
....
}
}
else
{
ModelState.AddModelError("", Constants.MessageStrings.NoUser);
return Json(new { status = "error", message = Constants.MessageStrings.NoUser });
}
}
}
else
{
.......
return Json(new { status = "error", message = Constants.MessageStrings.RequiredFields });
}
and this is my Ajax to call controller:
function resetPasswordHandler() {
var postResult = null;
var data = {
Email: document.getElementById('email').value
};
var path = "/forgotPassword";
var errorMessage = document.getElementById('Message');
$.ajax({
dataType: "text",
url: path,
data: data,
type: "POST",
cache: false,
success: function (result) {
postResult = $.parseJSON(result);
if (postResult.status == "success") {
$('#forgot').hide();
$('#forgot-thank-you').show();
return false;
}
else {
errorMessage.innerHTML = postResult.message;
}
},
error: function () {
errorMessage.innerHTML = "An error occured";
}
});
return false;
};
window.onkeydown = function () {
if (window.event.keyCode == '13') {
resetPasswordHandler();
}
}
return Json(new { status="success",message="what ever your msg"}, JsonRequestBehavior.AllowGet);
I would remove the click handler from the button, and handle the submit event of the relevant form.
You should give an id for easier targeting
#using (Html.BeginForm("forgotPassword", "Home", FormMethod.Post, new { id = "reset-form" }))
And simplify your script (since you are using jQuery) to
function resetPasswordHandler(event) {
var postResult = null,
data = {
Email: $('#email').val()
},
path = "/forgotPassword",
errorMessage = $('#Message');
event.preventDefault();
$.ajax({
dataType: "text",
url: path,
data: data,
type: "POST",
cache: false,
success: function(result) {
postResult = $.parseJSON(result);
if (postResult.status == "success") {
$('#forgot').hide();
$('#forgot-thank-you').show();
return;
} else {
errorMessage.html(postResult.message);
}
},
error: function() {
errorMessage.html("An error occured");
}
});
return false;
};
$('#reset-form').on('submit', resetPasswordHandler);
I call the Ajax to get the result from web API in my MVC project. in my local the page works but in production it is not working and giving me this error in .js file exactly at this line: $.ajax
http://mylink.cloudapp.azure.com/searchuser 404 (Not Found)
x.extend.ajax anonymous function
This is my .js file:
$(document).ready(function () {
$('#btnSearch').click(function (evt) {
// debugger;
if (ValidateInput()) {
var data = {
LastName: $.trim($('#LastName').val() || ''),
Zip: $.trim($('#Zip').val() || ''),
Ssn: $.trim($('#Ssn').val() || '')
};
var token = $('[name=__RequestVerificationToken]').val();
$.ajax({
dataType: "json",
//headers: { "__RequestVerificationToken": token },
data: data,
url: '/searchuser',
type: 'POST',
cache: false,
success: function (result) {
console.log(result);
if (result && result.success) {
$('#ApplicationId').val(result.data.applicantId);
if (result.data.exception == null) {
$('#stepTwo').show();
$('#EmailAddress').val(result.data.userEmailAddress);
}
else {
$('#txtareaResponse').val(result.data.exception);
}
}
},
error: function () { debugger; alert('failure'); }
});
}
});
and this is top of my view:

<script src="~/Scripts/Verify.js"></script>
and this is the controller method:
[AllowAnonymous]
[Route("searchuser")]
[HttpPost]
public async Task<ActionResult> SearchUser(UserInfo userInfo)
{
object userObject = null;
if (userInfo.LastName != null && userInfo.Zip != null && userInfo.Ssn != null)
{
string accessKey = CreateAccountKey(userInfo.LastName, userInfo.Zip, userInfo.Ssn);
UserKey userKey = new UserKey();
userKey.AccountKey = accessKey;
//var response = await httpClient.GetAsync(string.Format("{0}{1}/{2}", LoanApiBaseUrlValue, "/verifyuser", accessKey));
var response = await httpClient.PostAsJsonAsync(string.Format("{0}{1}", LoanApiBaseUrlValue, "/verifyuser"), userKey);
if (response.IsSuccessStatusCode)
{
userObject = new JavaScriptSerializer().DeserializeObject(response.Content.ReadAsStringAsync().Result) as object;
var json = response.Content.ReadAsStringAsync().Result;
var userVerify = new JavaScriptSerializer().Deserialize<VerifyUser>(json);
}
}
var respone = new
{
success = userObject != null,
data = userObject
};
return Json(respone, JsonRequestBehavior.AllowGet);
}
Try just returning an ActionResult
[AllowAnonymous]
[Route("searchuser")]
[HttpPost]
public ActionResult SearchUser(..){..}
also in your ajax call use the Razor syntax
$.ajax({
url: "#Url.Action("method", "Controller")",
type: "GET",
data: {},
success: function (data) {
//do stuff...
}
});
I have an $.ajax function on my page to populate a facility dropdownlist based on a service type selection. If I change my service type selection back and forth between two options, randomly the values in the facility dropdownlist will remain the same and not change. Is there a way to prevent this? Am I doing something wrong?
Javascript
function hydrateFacilityDropDownList() {
var hiddenserviceTypeID = document.getElementById('<%=serviceTypeID.ClientID%>');
var clientContractID = document.getElementById('<%=clientContractID.ClientID%>').value;
var serviceDate = document.getElementById('<%=selectedServiceDate.ClientID%>').value;
var tableName = "resultTable";
$.ajax({
type: 'POST',
beforeSend: function () {
},
url: '<%= ResolveUrl("AddEditService.aspx/HydrateFacilityDropDownList") %>',
data: JSON.stringify({ serviceTypeID: TryParseInt(hiddenserviceTypeID.value, 0), clientContractID: TryParseInt(clientContractID, 0), serviceDate: serviceDate, tableName: tableName }),
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (data) {
a(data);
}
,error: function () {
alert('HydrateFacilityDropDownList error');
}
, complete: function () {
}
});
}
function a(data) {
var facilityDropDownList = $get('<%=servicesFormView.FindControl("facilityDropDownList").ClientID%>');
var selectedFacilityID = $get('<%= selectedFacilityID.ClientID%>').value;
var tableName = "resultTable";
if (facilityDropDownList.value != "") {
selectedFacilityID = facilityDropDownList.value;
}
$(facilityDropDownList).empty();
$(facilityDropDownList).prepend($('<option />', { value: "", text: "", selected: "selected" }));
$(data.d).find(tableName).each(function () {
var OptionValue = $(this).find('OptionValue').text();
var OptionText = $(this).find('OptionText').text();
var option = $("<option>" + OptionText + "</option>");
option.attr("value", OptionValue);
$(facilityDropDownList).append(option);
});
if ($(facilityDropDownList)[0].options.length > 1) {
if ($(facilityDropDownList)[0].options[1].text == "In Home") {
$(facilityDropDownList)[0].selectedIndex = 1;
}
}
if (TryParseInt(selectedFacilityID, 0) > 0) {
$(facilityDropDownList)[0].value = selectedFacilityID;
}
facilityDropDownList_OnChange();
}
Code Behind
[WebMethod]

return result;
}
$get return XHR object not the return value of the success call and $get function isn't synchronous so you should wait for success and check data returned from the call
these two lines do something different than what you expect
var facilityDropDownList = $get('<%=servicesFormView.FindControl("facilityDropDownList").ClientID%>');
var selectedFacilityID = $get('<%= selectedFacilityID.ClientID%>').value;
change to something similar to this
var facilityDropDownList;
$.ajax({
url: '<%=servicesFormView.FindControl("facilityDropDownList").ClientID%>',
type: 'get',
dataType: 'html',
async: false,
success: function(data) {
facilityDropDownList= data;
}
});
