I have these ViewModels:
public class UserAddRoleListViewModel
{
public String Id { get; set; }
public String Name { get; set; }
}
public class SaveUserNewRoleViewModel
{
[Required]
public String RoleId { get; set; }
public String RoleName { get; set; }
public List<UserAddRoleListViewModel> RoleList { get; set; }
}
How can I pass an array of objects that have a format like this:
var object = {
Id: rowIdItem,
Name: rowItem
};
dataSet.push(object);
to my MVC Controller here:
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult VerifyRole(SaveUserNewRoleViewModel Input)
{
IEnumerable<object> errors = null;
if (ModelState.IsValid)
{
if(Input.RoleList[0] != null)
{
foreach (var item in Input.RoleList)
{
if (Input.RoleId == item.Id)
{
ModelState.AddModelError("RoleId", "Role already exists");
errors = AjaxError.Render(this);
return Json(new { success = false, errors });
}
}
return Json(new { success = true });
}
return Json(new { success = true });
}
else
{
errors = AjaxError.Render(this);
return Json(new { success = false, errors });
}
}
So far it seems like its always passing an nothing when I debug it
EDIT:
Just to clarify. I can already pass the item via ajax. It's just that when I debug, RoleList is empty.
This is my ajax function:
$(document).on("submit", "#modal", function (e) {
e.preventDefault();
var selectedText = $("##Html.IdFor(m=>m.RoleId) :selected").text();
var selectedId = $("##Html.IdFor(m=>m.RoleId)").val();
var form_data = $(this).serializeArray();
form_data.push({ name: "RoleList", value: dataSet });
console.log(form_data);
rowIdItem = selectedId;
rowItem = selectedText;
$("#close").trigger("click");
$.ajax({
url: "#Url.Action("VerifyRole", #ViewContext.RouteData.Values["controller"].ToString())",
method: "POST",
data: form_data,
contentType: "application/x-www-form-urlencoded; charset=UTF-8",
success: function (result) {
if (result.success) {
rowIdItem = selectedId;
rowItem = selectedText;
$("#close").trigger("click");
return;
}
$.each(result.errors, function (index, item) {
// Get message placeholder
var element = $('[data-valmsg-for="' + item.propertyName + '"]');
element.empty();
// Update message
element.append($('<span></span>').text(item.errorMessage));
// Update class names
element.removeClass('field-validation-valid').addClass('field-validation-error');
$('#' + item.propertyName).removeClass('valid').addClass('input-validation-error');
});
}
});
return false;
});
EDIT 2:
Added code that fills dataSet:
$(document).on($.modal.AFTER_CLOSE, function (event, modal) {
dataSet.push(object);
table.row.add(object).draw();
$("#modal").empty();
});
Javascript
$("#myBtn").click(function () {
var dataSet= [];
var obj = {
Id: rowIdItem,
Name: rowItem
};
dataSet.push(obj);
var data = {
"RoleId": '1',
"RoleName ": 'roleName',
"RoleList": dataSet
};
$.ajax({
type: "POST",
traditional:true,
url: "controller/VerifyRole",
content: "application/json;",
dataType: "json",
data: data ,
success: function () {
}
});
});
Controller/Action
[HttpPost]
public ActionResult VerifyRole(SaveUserNewRoleViewModel input)
{
...
}
Try this:)
$(document).on("submit", "#modal", function (e) {
e.preventDefault();
var selectedText = $("##Html.IdFor(m=>m.RoleId) :selected").text();
var selectedId = $("##Html.IdFor(m=>m.RoleId)").val();
var form_data = {};
form_data.RoleId = selectedId;
form_data.RoleName =selectedText;
console.log(form_data);
rowIdItem = selectedId;
rowItem = selectedText;
$("#close").trigger("click");
$.ajax({
url: "#Url.Action("VerifyRole", #ViewContext.RouteData.Values["controller"].ToString())",
method: "POST",
data: JSON.stringify(form_data),
contentType: "application/x-www-form-urlencoded; charset=UTF-8",
success: function (result) {
if (result.success) {
rowIdItem = selectedId;
rowItem = selectedText;
$("#close").trigger("click");
return;
}
$.each(result.errors, function (index, item) {
// Get message placeholder
var element = $('[data-valmsg-for="' + item.propertyName + '"]');
element.empty();
// Update message
element.append($('<span></span>').text(item.errorMessage));
// Update class names
element.removeClass('field-validation-valid').addClass('field-validation-error');
$('#' + item.propertyName).removeClass('valid').addClass('input-validation-error');
});
}
});
return false;
});
my example with datasets:
$("body").on("click", "#btnSave", function () {
var ops = new Array();
$("#table TBODY TR").each(function () {
var row = $(this);
var ps = {};
ps.colname1 = row.find("TD").eq(0).html();
ps.colname2 = row.find("TD").eq(1).html();
ps.colname3= row.find("TD").eq(2).html();
ops.push(ps);
});
var item = {};
item.nam1 = "test";
item.List = ops;
$.ajax({
type: "POST",
url: " ...",
data: JSON.stringify(item),
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (r) {
}
});
});

I have a model created in javascript as follows
function Vehicle() {
this.type = 'Vehicle';
this.data = {
VehicleKey: null
}
};
I have a similar model created in c# as follows
public class Vehicle
{
public string VehicleKey { get; set; }
}
Now I am building an array of VehicleKeys in javascript as follows
function GetVehicleDetails(inputarray) {
var vehicleKeys = [];
for (var i = 0; i < inputarray.length; i++) {
var vehicleObject = new Vehicle();
vehicleObject.data.VehicleKey = inputarray[i].VehicleKey ? inputarray[i].VehicleKey : null;
vehicleKey.push(vehicleObject.data);
}
return vehicleKeys ;
}
I am calling the $.post(url, data) as follows
var objectToSend = GetVehicleDetails(selectedVehicles);
var data = JSON.stringify({
'vehicles': objectToSend
});
$.post(url, data)
.done(function (result) {
if (result) {
download(result, 'VehicleReport.xlsx', { type: 'application/octet-stream' });
console.log("Report created successfully");
}
else {
console.log("Error creating report");
}
}).fail(function (error) {
console.log("Error creating report.");
});
The MVC Controller has a method to accept Vehicles with multiple VehicleKeys coming from javascript
public byte[] CreateVehicleReport(List<Vehicle> vehicles)
{
//Generation of report and pass it back to javascript
}
Here I am able to submit the data in javascript as 10 and 11 for Vehicles but when it catches the c#, the count is coming as 0.
Any help would be greatly appreciated.
$.post is not posted Content-Type json data so you need to use $.ajax
function GetVehicleDetails(inputarray) {
var vehicleKeys = [];
for (var i = 0; i < inputarray.length; i++) {
var vehicleObject = {}; // Set Object
vehicleObject.VehicleKey = inputarray[i].VehicleKey ? inputarray[i].VehicleKey : null;
vehicleKeys.push(vehicleObject);
}
return vehicleKeys;
}
var objectToSend = GetVehicleDetails(selectedVehicles);
$.ajax({ type: 'POST',
url: url,
data: JSON.stringify(objectToSend),
contentType: "application/json",
dataType: 'json',
success: function (data) {
alert('data: ' + data);
},
}).done(function () {
if (result) {
console.log("Report created successfully");
}
else {
console.log("Error creating report");
}
}).fail(function () {
console.log("Error creating report.");
});
C# Method
[HttpPost("CreateVehicleReport")]
public byte[] CreateVehicleReport([FromBody]List<Vehicle> vehicles)
{
return null;
//Generation of report and pass it back to javascript
}
I used a similar approach once but with ajax and it went like this:
fill your array directly with the properties inside your class as object { } make sure the names are exactly the same:
function GetVehicleDetails(inputarray) {
var data_Temp = [];
for (var i = 0; i < inputarray.length; i++) {
var _vehiclekey = inputarray[i].VehicleKey ? inputarray[i].VehicleKey : null;
data_Temp.push({ VehicleKey : _vehiclekey });
});
return data_Temp;
}
var objectToSend = GetVehicleDetails(selectedVehicles);
var JsonData = JSON.stringify({ vehicles: objectToSend });
$.ajax({
type: "POST",
contentType: "application/json",
url: "/controllerName/actionName", //in asp.net using mvc ActionResult
datatype: 'json',
data: JsonData,
success: function (response) {
},
error: function (response) {
console.log(response);
}
});
And the ActionResult in the controller should look like this:
[HttpPost]
public ActionResult Create(List<Vehicle> vehicles)
{
//do whatever you want with the class data
}
I don't know if this is helpful for you but this always works for me and i hope it helps.
I need some help. I write little app using ASP.NET MVC5 with JavaScript, jQuery, Ajax... and I can't send data from javascript to MVC Controller and change the model.
ViewModel
public class MyViewModel
{
//...
public string SearchString { get; set; }
public int? FirstInt { get; set; }
public int? SecondInt { get; set; }
}
Javascript
function keystroke() {
var a = 0, b = 0;
$('#search').keyup(function (event) { a = 1; });
$('#search').keydown(function (event) { b = 1; });
$("#search").keypress(function (event) {
if (e.which === 13) {
e.preventDefault();
$('form').click(function () {
sendForm(a, b);
});
}
});
};
function sendForm(a, b) {
$.ajax({
url: #Url.Action("Index", "Home"),
type: 'POST',
contentType: 'application/json',
data: JSON.stringify({
FirstInt: a,
SecondInt: b
}),
success: function () {
alert('success');
}
});
};
View
#using (Html.BeginForm("Index", "Home", FormMethod.Post, new { #class = "form-inline", role = "form" }))
{
<div class="form-group has-feedback">
#Html.TextBox("SearchString", ViewBag.SearchFilter as string, new
{
#class = "form-control",
onclick="keystroke()",
id = "search"
})
</div>
}
Controller
public async Task<ActionResult> Index(MyViewModel model)
{
//...
if (model.SearchString != null)
{
//...
var a = model.FirstInt;
var b = model.SecondInt;
}
//...
return View(model);
}
Help me, please, to send all the values to controller. Those that changed in JavaScript and what I enter in the textbox. Thanks.
Javascript Code:
function keystroke() {
var a = 0, b = 0;
$('#search').keyup(function (event) { a = 1; });
$('#search').keydown(function (event) { b = 1; });
$("#search").keypress(function (event) {
if (e.which === 13) {
e.preventDefault();
$('form').click(function () {
var text = $("#search").val()
sendForm(a, b, text);
return false;
});
}
});
};
function sendForm(a, b, text) {
var data = {FirstInt: a,SecondInt: b,SearchString: text}
$.ajax({
url: 'Home/Index',
type: 'POST',
contentType: 'application/json',
data: data,
success: function () {
alert('success');
}
});
};
Controller Code
[HttpPost]
public async Task<ActionResult> Index(MyViewModel model)

//...

{
//...
var a = model.FirstInt;
var b = model.SecondInt;

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]
public static string HydrateFacilityDropDownList(int serviceTypeID, int clientContractID, DateTime serviceDate, string tableName)
{
List<PackageAndServiceItemContent> svcItems = ServiceItemContents;
List<Facility> facilities = Facility.GetAllFacilities().ToList();
if (svcItems != null)
{
// Filter results
if (svcItems.Any(si => si.RequireFacilitySelection))
{
facilities = facilities.Where(f => f.FacilityTypeID > 0).ToList();
}
else
{

}
$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;
}
});
I try to pass my grid Data from jQuery to the MVC Action via Ajax.
I have a button "Save" on my page, and this is jQuery code for click:
var result = [];
$('#btnSave').click(function () {
$('#tblMatters tbody tr.mattersRow').each(function () {
var item = {};
if ($(this).find('td.qbmatter > div.dropdown').length > 0) {
item.QBMatter = $(this).find('td.qbmatter > div.dropdown > a').text();
} else {
item.QBMatter = $(this).find('td.qbmatter').text();
}
item.Hours = $(this).find('td.hours').text();
item.Person = $(this).find('td.person').text();
if ($(this).find('td.rate > div.dropdown').length > 0) {
item.Rate = $(this).find('td.rate > div.dropdown > a').text();
} else {
item.Rate = $(this).find('td.rate').text();
}
item.Amount = $(this).find('td.amount').text();
result.push(item);
});
$.ajax({
url: "/Home/SaveQBMatter",
type: "POST",
data: { 'Matters': result },
dataType: "json",
traditional: true,
contentType: "application/json; charset=utf-8",
success: function (data) { alert("Success!"); },
error: function () { alert("An error has occured!!!"); }
});
});
I checked the result array and it's correct. It contains every value that should be.
In my HomeController I have the following model for my data:
public class QBMatter
{
public string QBDescription { get; set; }
public string Person { get; set; }
public decimal Hours { get; set; }
public int Rate { get; set; }
public decimal Amount { get; set; }
}
And the following Action:
public ActionResult SaveQBMatter (QBMatter[] Matters)
{
DBAccess dba = new DBAccess();
int QBMatterID = 0;
foreach (QBMatter qb in Matters)
{
dba.InsertQBMatter(qb.QBDescription, qb.Person, qb.Hours, qb.Rate, qb.Amount, ref QBMatterID);
}
return RedirectToAction("Home", "Index", "Home");
}
But I always getting the "An error has occured!!!" result... And I even don't get to the action, so error somewhere on the ajax level...
What I'm doing wrong?
You need to stringify the data while sending it.
Try:
$.ajax({
url: "/Home/SaveQBMatter",
type: "POST",
data: JSON.stringify({ 'Matters': result }),
dataType: "json",
contentType: "application/json; charset=utf-8",
success: function (data) {
alert("Success!");
},
error: function () {
alert("An error has occured!!!");
}
});
I'm using ajax to get the corresponding row values in modal popup for edit in MVC 4 razor..
for username textbox i get like this...
#Html.TextBoxFor(u => u.useredit.userName,new { #class = "input-xlarge focused", id="Edituname", type = "text" })

#Html.CheckBoxFor(u => u.useredit.isActive, new {id="EditActiv"})
i'm getting plain checkbox.where i gone wrong..or is there any other way for check box,,

i'm getting the unchecked checkbox in edit popup..pls smeone help me..thnks in advance...
For your view
#Html.CheckBoxFor(u => u.useredit.isActive, new {id="EditActiv"})
Make the below changes and see if it working
[HttpPost]
public ActionResult getUserState(int userid)
{
data[9] = user.isActive.ToString()
return Json(data);
}
Try use prop() method
<script type="text/javascript">
function Getuser(_StateId) {
var url = "/admin/getUserState/";
$.ajax({
url: url,
data: { userid: _StateId },
cache: false,
type: "POST",
success: function (data) {
var editCheck=(data[9]=== 'true')?true:false;
$('#EditActiv').prop('checked',editCheck); //use prop()
}
});
