How to make delete button an html button instead of an ajax button

I want to change the delete button from an ajax button to an html button. I am currently using ajax/javascript for the delete button. When I click the Delete button, a modal window to confirm that I want to delete comes up and once I click confirm it will delete the vote. The Delete Action redirect I changed to RedirectToAction but the page errors out (InvalidOperationException: No route matches the supplied values.). The redirect isn't right I believe or maybe I need another return for the method?
<div class="modal fade" id="delete-vote-modal" tabindex="-1"
role="dialog"
data-backdrop="static">
<form method="post" asp-controller="Discussion" asp-action="DeleteVote"
enctype="multipart/form-data">
<input id="packet-item-id" asp-for="#Model.PacketItemId" type="hidden"
/>
<input id="voting-type" asp-for="#Model.VotingType" type="hidden"
/>
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title">Delete Vote</h5>
<button type="button" class="close" data-dismiss="modal"
aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<input type="hidden" name="voteId" id="voteId" value="" />
Do you want to delete this vote ?
<div style="text-align: center; display: none"
id="loaderDiv">
<img src="~/images/loading.gif" width="150" />
</div>
</div>
<div class="modal-footer">
<a href="#" class="btn btn-default" data-
dismiss="modal">Cancel</a>
<input type="submit"
value="Confirm"
class="btn btn-success col-sm-12 col-md-2 col-lg-2"
data-action="submit" />
</div>
</div>
</div>
</form>
[HttpPost]
public async Task<IActionResult> DeleteVote(long voteId, int
packetItemId, string votingType, CancellationToken cancellationToken)
{
try
{
await _discussionService.DeleteVoteAsync(
voteId,
cancellationToken)
.ConfigureAwait(true);
TempData.Put(key: TempDataKey.Vote.DeleteMessage,
StatusMessageModel.Create(UserStringsService.VoteDeletedSuccessfully,
false));
return RedirectToAction("/Vote?packetItemId=" + packetItemId +
"&votingType=" + votingType);
//return Json(new { isSuccess = true, statusMessage =
UserStringsService.VoteDeletedSuccessfully });
}
catch
{
Logger.LogError($"Error in deleting the Vote Id: {voteId}");
TempData.Put(key: TempDataKey.Vote.DeleteMessage,
StatusMessageModel.Create(UserStringsService.VoteDeleteFailed, false));
return RedirectToAction("/Discussion/Vote?packetItemId=" +
packetItemId + "&votingType=" + votingType);
//return Json(new { isSuccess = false, statusMessage =
UserStringsService.VoteDeleteFailed });
}
}

From the code, the bakend need to receive the data with an object.
Note: the route parameter in Redirect is an absolute path.
[HttpPost]
public async Task<IActionResult> DeleteVote(ViewModel viewModel, CancellationToken cancellationToken)
{
return Redirect("/Discussion/Vote?packetItemId="+viewModel.PacketItemId+ "&votingType="+viewModel.VotingType);
}
public IActionResult Vote(int packetItemId, string votingType)
{
return Ok(new { packetItemId = packetItemId, votingType = votingType });
}
Model
public class ViewModel
{
public int PacketItemId { get; set; }
public string VotingType { get; set; }
//...

ASP.NET Core MVC update partial view after submitig a form

This is in ASP.NET Core MVC 2.1.
What I have is a main Index page on witch I load all my partial views.
<button type="button" id="CreateButton" class="btn btn-success" style="margin-top: 20px;">Nova osoba</button>
<button type="button" id="LoadDataButton" class="btn btn-info" style="margin-top: 20px;">Ucitati podatke</button>
<div id="CreateEditView">
</div>
<div id="TablePeopleView">
</div>
The way I load data into "TablePeopleView" is like this.
function AjaxCall(url) {
$("#TablePeople").replaceWith(
$.ajax({
url: url,
method: "POST",
success: function (html) {
$("#TablePeopleView").html(html);
}
}));
}
$(document).ready(function () {
AjaxCall("#Url.Action("IndexAjax")");
});
This calls the IndexAjax method from the controller and creates this partial view inside "TablePeopleView"
#model List<Person>
<table style="margin-top: 20px;" class="table table-condensed" id="TablePeople">
<thead>
<tr>
<th>ID</th>
<th>Ime</th>
<th>Prezime</th>
<th>Grad</th>
<th>Postanski broj</th>
<th>Broj mobitela</th>
<th> </th>
<th> </th>
</tr>
</thead>
<tbody>
#foreach (var item in Model)
{
<tr>
<td>#item.ID</td>
<td>#item.FirstName</td>
<td>#item.LastName</td>
<td>#item.CityName</td>
<td>#item.PostalCode</td>
<td>#item.MobileNumber</td>
<td>
<button type="button" class="btn btn-toolbar EditButton" data-url="#Url.Action("Edit","Zadatak")/#item.ID">
Uredi osobu
</button>
</td>
<td>
<button type="submit" class="btn btn-danger DeleteButton" data-url="#Url.Action("Delete","Zadatak")/#item.ID">
Obriši osobu
</button>
</td>
</tr>
}
</tbody>
</table>
And it works fine, gets the data and shows it on table.
When I want to create a new person I click on the "CreateButton" and get a new partial view inside "CreateEditView". The partial view looks like this.
#model Person
<div class="modal fade" id="CreateOrEditModal" role="dialog">
<div class="modal-dialog">
<!-- Modal content-->
<div class="modal-content">
<div class="modal-header">
#if (Model == null)
{
<h4 class="modal-title">Nova osoba</h4>
}
else
{
<h4 class="modal-title">Uredi osobu</h4>
}
</div>
<div class="modal-body">
<form asp-controller="Zadatak" id="CreateOrEditModalForm">
<div class="form-group">
<label class="control-label">Ime osobe</label>
<input asp-for="FirstName" class="form-control" id="FirstName" />
<span asp-validation-for="FirstName" class="text-danger"></span>
</div>
<div class="form-group">
<label class="control-label">Prezime osobe</label>
<input asp-for="LastName" class="form-control" id="LastName" />
<span asp-validation-for="LastName" class="text-danger"></span>
</div>
<div class="form-group">
<label class="control-label">Naziv grada</label>
<input asp-for="CityName" class="form-control" id="CityName" />
<span asp-validation-for="CityName" class="text-danger"></span>
</div>
<div class="form-group">
<label class="control-label">Poštanski broj</label>
<input asp-for="PostalCode" class="form-control" id="PostalCode" onkeypress="return isNumberKey(event)" />
<span asp-validation-for="PostalCode" class="text-danger"></span>
</div>
<div class="form-group">
<label class="control-label">Mobilni broj</label>
<input asp-for="MobileNumber" class="form-control" id="MobileNumber" onkeypress="return isNumberKey(event)" />
<span asp-validation-for="MobileNumber" class="text-danger"></span>
</div>
<div class="form-group">
<input type="submit" value="Pospremi osobu" class="btn btn-default" id="SavePerson" />
</div>
</form>
</div>
<div class="modal-footer">
<button type="button" id="ClosePerson" class="btn btn-default" data-dismiss="modal">Zatvori</button>
</div>
</div>
</div>
</div>
The way I get the partial view to show up in "CreateEditView" is like this.
$('#CreateButton').click(function () {
var url = "#Url.Action("Create","Zadatak")";
$("#CreateEditView").load(url, function () {
$("#CreateOrEditModal").modal("show");
});
});
The way I save date from the form "CreateOrEditModalForm" is with this.
$("#CreateEditView").on("click", "#SavePerson", function (event) {
$("#CreateOrEditModalForm").removeData('validator');
$("#CreateOrEditModalForm").removeData('unobtrusiveValidation');
$.validator.unobtrusive.parse("#CreateOrEditModalForm");
$("#CreateOrEditModalForm").validate();
if ($("#CreateOrEditModalForm").valid()) {
$("#CreateOrEditModal").modal("hide");
}
});
I had to do it like this because it is loaded through a partial view witch is not loaded on page load.
After the form is validated it calls the "Create" method from the controller witch looks like this.
[HttpPost]
public IActionResult Create(Person model)
{
if (ModelState.IsValid)
{
this._dbContext.People.Add(model);
this._dbContext.SaveChanges();
return NoContent();
}
return NoContent();
}
Now this is where my problem comes I think. If the "ModelState.IsValid" is valid the new person will be saved to the DB and it will return NoContent. I put no content so the page does not refresh but if I put return RedirectToAction(nameof(IndexAjax)); like I did in the begginig it just loads the partila view in a new page like this.
I do not want that to happen, I just want the table to be refreshed with the new person while staying on the page.

Ajax allows websites to load content onto the screen without refreshing the page.
Here is a working demo you could check:
Model:
public class Person
{
public int ID { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string CityName { get; set; }
public string PostalCode { get; set; }
public string MobileNumber { get; set; }
}
View(Views/Zadatak/Index.cshtml):
<button type="button" id="CreateButton" class="btn btn-success" style="margin-top: 20px;">Nova osoba</button>
<button type="button" id="LoadDataButton" class="btn btn-info" style="margin-top: 20px;">Ucitati podatke</button>
<div id="CreateEditView">
</div>
<div id="TablePeopleView">
</div>
#section Scripts
{ //be sure add _ValidationScriptsPartial....
#{await Html.RenderPartialAsync("_ValidationScriptsPartial");}
<script>
function AjaxCall(url) {
//the same as yours..
}
$(document).ready(function () {
AjaxCall("#Url.Action("IndexAjax")");
});
$('#CreateButton').click(function () {
//the same as yours..
});
$("#CreateEditView").on("click", "#SavePerson", function (event) {
$("#CreateOrEditModalForm").removeData('validator');
$("#CreateOrEditModalForm").removeData('unobtrusiveValidation');
$.validator.unobtrusive.parse("#CreateOrEditModalForm");
$("#CreateOrEditModalForm").validate();
if ($("#CreateOrEditModalForm").valid()) {
$("#CreateOrEditModal").modal("hide");
//add the following code....
$("#TablePeople").replaceWith(
$.ajax({
url:"#Url.Action("Create", "Zadatak")",
method: "POST",
data: $("#CreateOrEditModalForm").serialize(),
success: function (html) {
$("#TablePeopleView").html(html);
}
}));
}
});
</script>
}
Be sure modify your CreateEditView.cshtml:
#model Person
<div class="modal fade" id="CreateOrEditModal" role="dialog">
//...
<div class="form-group">
#*change type="submit" to type="button"*#
<input type="button" value="Pospremi osobu" class="btn btn-default" id="SavePerson" />
</div>
</form>
</div>
<div class="modal-footer">
<button type="button" id="ClosePerson" class="btn btn-default" data-dismiss="modal">Zatvori</button>
</div>
</div>
</div>
</div>
Controller:
public class ZadatakController : Controller
{
private readonly YourContext _context;
public ZadatakController(YourContext context)
{
_context = context;
}
[HttpGet]
public async Task<IActionResult> Index()
{
return View();
}
[HttpPost]
public async Task<IActionResult> IndexAjax()
{
//change here....
return PartialView("_IndexTable", await _context.Person.ToListAsync());
}
public IActionResult Create()
{
return PartialView("CreateEditView");
}
[HttpPost]
public async Task<IActionResult> Create(Person person)
{
if (ModelState.IsValid)
{
_context.Add(person);
await _context.SaveChangesAsync();
//change here....
return PartialView("_IndexTable", await _context.Person.ToListAsync());
}
return View(person);
}
}
Result:

Modal Pop-Up Not Passing iFormFile Data On JavaScript Ajax Intercept

This is sort of an add-on to my previous question:
Modal Pop-Up Not Closing Properly After Form Submission
I'm trying to reuse the modal pop-up functionality for another pop-up on the same page. This time I am using it to upload a file. This is the javascript in question:
$('body').on('click', '.relative', function (e) {
e.preventDefault();
var form = $(this).parents('.modal').find('form');
var actionUrl = form.attr('action');
var dataToSend = form.serialize();
$.post(actionUrl, dataToSend).done(function (data) {
$('body').find('.modal-content').html(data);
var isValid = $('body').find('[name="IsValid"]').val() == 'True';
if (isValid) {
$('body').find('#modal-container').modal('hide');
window.location.href = "/Issue/Edit";
}
});
})
I inadvertently misspelled "relative" on the submit button of this form:
#model Models.AttachmentModel
<!--Modal Body Start-->
<div class="modal-content">
<input name="IsValid" type="hidden" value="#ViewData.ModelState.IsValid.ToString()" />
<!--Modal Header Start-->
<div class="modal-header">
<h4 class="modal-title">Upload File</h4>
<button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button>
</div>
<!--Modal Header End-->
<form asp-action="FileUpload" method="post" enctype="multipart/form-data" asp-controller="Attachment">
#Html.AntiForgeryToken()
<div class="modal-body form-horizontal">
<div>
<p>Upload a file using this form:</p>
<input type="file" name="file" />
<span asp-validation-for="#Model.aFileData" class="text-danger"></span>
</div>
<div>
<p>Enter a file description</p>
<input id="attachment" asp-for="#Model.aIssueAttachmentDescription" class="form-control" />
<span asp-validation-for="#Model.aIssueAttachmentDescription" class="text-danger"></span>
<input id="issueid" type="hidden" asp-for="#Model.issueId" class="form-control" value="#ViewBag.id" />
</div>
<!--Modal Footer Start-->
<div class="modal-footer">
#*<button type="submit" class="btn btn-success fileuploadmodal" data-save="modal">Upload</button>*#
<button data-dismiss="modal" id="cancel" class="btn btn-default" type="button">Cancel</button>
<input type="submit" class="btn btn-success realative" id="btnSubmit" data-save="modal" value="Upload">
</div>
<div class="row">
</div>
</div> <!--Modal Footer End-->
</form>
</div>
<script type="text/javascript">
$(function () {
});
</script>
With the word "relative" misspelled, the file information is being sent to the action in the controller(see below). My guess is the Javscript isn't catching the click action ($('body').on('click', '.relative', function (e)). When I spell "relative" correctly the file information is NULL:
public async Task<IActionResult> FileUpload(IFormFile file, IFormCollection collection)
{ //do something
}
What needs to change with the Javascript (or my form/controller) to get the file information? In both cases the collection information is being passed. Is there a way to get the file information added to the collection?
--------- More Info based on #Rena answer
Let me expand some more on the original code and how this works. I have a page that has a modal section that will be populated with different partial views depending upon what I want displayed in the modal. On the Main page it has the following Javascript section:
<script>
$('body').on('click', '.modal-link', function () {
var actionUrl = $(this).attr('href');
$.get(actionUrl).done(function (data) {
$('body').find('.modal-content').html(data);
});
$(this).attr('data-target', '#modal-container');
$(this).attr('data-toggle', 'modal');
});
$('body').on('click', '.relative', function (e) {
e.preventDefault();
var form = $(this).parents('.modal').find('form');
var actionUrl = form.attr('action');
var dataToSend = form.serialize();
$.post(actionUrl, dataToSend).done(function (data) {
$('body').find('.modal-content').html(data);
var isValid = $('body').find('[name="IsValid"]').val() == 'True';
if (isValid) {
$('body').find('#modal-container').modal('hide');
window.location.href = "/Issue/Edit";
}
});
})
$('body').on('click', '.close', function () {
$('body').find('#modal-container').modal('hide');
});
$('#CancelModal').on('click', function () {
return false;
});
$("form").submit(function () {
if ($('form').valid()) {
$("input").removeAttr("disabled");
}
});
</script>
I took what was provided by #Rena and inserted it into this section, but found that the Modal wouldn't close (although the data from the form in the partial view was now getting passed). I tried changing the .realative to another value on both the partial view and the javascript, but it made no difference. I then tried what #mj313 suggested in the preceding posts by changing the provided script like this to redirect to /Issue/Edit but that didn't work either.:
}).done((response, textStatus, xhr) => {
$('body').find('.modal-content').html(data);
var isValid = $('body').find('[name="IsValid"]').val() == 'True';
if (isValid) {
$('body').find('#modal-container').modal('hide');
window.location.href = "/Issue/Edit";
}
});
So while I can now pass data I can't close the Modal.

Here is the code for the file Upload
[HttpPost]
public async Task<IActionResult> FileUpload(IFormFile file, IFormCollection collection)
{
if (file == null)
{
ModelState.AddModelError("aFileData", "Please select a file.");
}
if (collection["aIssueAttachmentDescription"] == "")
{
ModelState.AddModelError("aIssueAttachmentDescription", "Please provide a description for the file.");
}
if (!ModelState.IsValid)
{
return PartialView("_UploadFile");
}
var formFileContent =
await FileHelpers.ProcessFormFile<BufferedSingleFileUploadDb>(
file, ModelState, _permittedExtensions,
_fileSizeLimit);
var thefile = new AttachmentModel
{
aFileData = formFileContent,
aFileName = file.FileName,
aIssueAttachmentDescription = collection["aIssueAttachmentDescription"],
aFileSize = file.Length,
aFileType=file.ContentType,
issueId = collection["issueId"]
};
string result = _adoSqlService.InsertFile(thefile);
ViewBag.ID = collection["issueId"];
ViewBag.JumpToDivId = "upload";
return PartialView("_UploadFile");
}
You can see in the code above that I add in model errors if the file is not selected or the description is not filled in. These are not being shown.
I can live with the collection returning the entire Edit forms data, but ideally it should only return the fields on the _UploadFile.cshtml form (aIssueAttachmentDescription, issueId)
Anything you can provide that fixes the display of the model errors as well as a way to simplify my code would be greatly appreciated.

With the word "relative" misspelled, the file information is being sent to the action in the controller(see below). My guess is the Javscript isn't catching the click action ($('body').on('click', '.relative', function (e)). When I spell "relative" correctly the file information is NULL
The <input type="submit"> defines a submit button which submits all form values to a form-handler.So although you misspelled the word,it also could submit to the action successfully by default.
For how to use ajax to pass form data with file,you could follow:
#model Mvc3_0.Controllers.HomeController.AttachmentModel
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal">
Launch demo modal
</button>
<!-- Modal -->
<div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">

Update1:
.done((response, textStatus, xhr) => {

Update2:
By using your code,I find that you add the modal html in a form which is in the main page.This will cause the form in modal which is in _UploadFile.cshtml could not generate well in my project.Here is the whole working demo:
Main Page:
#model AttachmentModel
<div class="row">
<div>
//change here.....
<div id="modal-container" class="modal fade" tabindex="-1">
<div class="modal-dialog modal-lg">
<div class="modal-content">
</div>
</div>
</div>
<form asp-action="Edit">
<br />
#*This table contains the second control that generates a modal which contains the _UploadFile.cshtml*#
<table id="upload" width="100%">
<tr>
<td width="90%" style="padding:5px 5px 0px 5px;background-color:midnightblue;color:white">
<label class="control-label">Upload Attachments</label>
</td>
<td style="background-color: midnightblue; padding-right:5px">
<a href="#Url.Action("FileUpload", new { controller = "Attachment", issueid = "1" })"
class="modal-link btn btn-success">Upload Files</a>

Load DataTable data to a Edit Modal

I am trying to create an edit function for my data table. The data table is created using Yajra Data tables. Everything working fine unless when I try to load existing data into the edit modal it fails. No error is showing but the modal does not launch. I have only included a little portion of my code here for easy reference.
Modal:

jquery funtion:
// Edit action
$(document).on('click', '.updateStatus', function(){
$tr = $(this).closest('tr');
var data = $tr.clidren("td").map(function(){
return $(this).text();
}).get();
console.log(data);
$('#id').val(data[0]);
$('#job_id').val(data[2]);
$('#stage_1').val(data[3]);
$('#conversion').val(data[4]);
$('#updateStatusModal').modal('show');
});
I tried this method I found but this is not working. Can anyone provide me any pointers here?

I've just didn't seen your front scripts (also back-end codes), but instead I can share my implementation for that you need. It works perfectly like showed in this (screenshot).
Here I'll put front and back codes. There is functionality for editing existsing Datatable record, also record deletion.

I think this can help you and others to build wanted functionality. Here this could be also with more hint-comments, but as it not small, I can answer later via post comments.

i am building a Laravel ERP-like web application and am implementing a CRUD function modal like you. I have made mine a server-side processing application with resource APIs in Laravel. Well, please be reminded that i have cut the #extends(layout.app) & #section('stylesheet') parts to go right into the answer. You should extend them in your own application to make everything work.

I have not included any protection in it like gate, auth or so. But basically this is the skeleton of doing CRUD with dataTable in Laravel framework with both JS, Ajax, Jquery, PHP all in one. Kindly be reminded that the queries for such CRUD actions are directly linked to the Database server. If you want to show data processed by the DataTable, use your own jquery function to fetch and show them on the modal. My answer is not the best but i hope it helps you >:)
(I could not post a picture to show you here as i dont have enough reputation lol. gg)

Now the question is when the page loaded, I found the the code reached click event script. It is strange. When I click the button, it doesn't reach the script. But it goes to the controller action method,
[HttpPost]
public ActionResult LanguageEdit(MyModel model)
{
I guess some stupid error to cause the onclick event not fired correctly, but I can't figure it out.
EDIT
public ActionResult LanguageEdit(int id)
{
var model = new CountryLanguageModel();
model.CountryId = id;
model.CountryLanguageQuestion = MyService.GetQuestion(x => x.CountryId == id);
return View(model);
}

Add type='button' attribute to your buttons, if not it will behave as a submit button.

can you change button to a ?
<button class="btn btn-success" id="editLanguage">Edit</button>
to
<a href="/Country/LanguageEdit?id=#Model.CountryId" class="btn btn-success" />
Some more information
if you want to GET somekind of HTML use HTTPGET instead of HTTPPOST.
Use HTTPPOST if you want to send some kind of information, that server should for example save. Use HTTPGET if you want to render some kind of view ( for example get a new view),
Your Action required 'MyModel model' not a id.

As per your comment you may get this behaviour:
why it was fired when page loaded, I didn't click the button at all.
When your javascript code not inside the button click event and instead it is inside any of the other event such document ready or page load ..etc.
So kindly check the event of javascript and surely you will get the direction to solution .
After checked ,If you ,still had the same problem. kindly show us your javascript so that it will be useful to help you further
Thanks
