Using Modal JavaScript in the Partial View of .NET CORE will not work after Ajax Post

I use the Modal display field in the Partial View to input data for the User, and use data-url=#url.action("Create") in the main screen to call Modal.
And wrote Autocomplete JavaScript in Partial View.
It works perfectly before using Ajax Post.
But after going through Ajax, the JavaScript cannot be used when it returns because of an error.
How can I make corrections?
Main View
<div id="PlaceHolderHere" data-url="#Url.Action("Create")"></div>
Ajax Code
$(function () {
var PlaceHolderElement = $('#PlaceHolderHere');
$('button[data-toggle="ajax-modal"]').click(function (event) {
event.preventDefault();
var url = $(this).data('url');
$.get(url).done(function (data) {
PlaceHolderElement.html(data);
PlaceHolderElement.find('.modal').modal('show');
});
});
PlaceHolderElement.on('click', '[data-save="modal"]', function (event) {
event.preventDefault();
var form = $(this).parents('.modal').find('form');
var actionUrl = form.attr('action');
var sendData = new FormData(form.get(0));
console.log(sendData);
$.ajax({
url: actionUrl,
method: 'post',
data: sendData,
processData: false,
contentType: false,
cache: false,
success: function (redata) {
console.log(redata);
if (redata.status === "success") {
PlaceHolderElement.find('.modal').modal('hide');
}
else {
var newBody = $('.modal-body', redata);
var newFoot = $('.modal-footer', redata);
PlaceHolderElement.find('.modal-body').replaceWith(newBody);
PlaceHolderElement.find('.modal-footer').replaceWith(newFoot);
}
},
error: function (message) {
alert(message);
}
})
})
})
Partial View of JavaScript part
#{await Html.RenderPartialAsync("_ValidationScriptsPartial");}
<script src="~/bootstrap-autocomplete/dist/latest/bootstrap-autocomplete.min.js"></script>
$('#BossName').autoComplete({
resolver: 'custom',
minLength: 2,
formatResult: function (item) {
return {
value: item.value,
text: "[" + item.value + "] " + item.text,
}
},
noResultsText:'There is no matching data, please confirm whether there is data in the company field',
events: {
search: function (qry, callback) {
// let's do a custom ajax call
$.ajax(
'#Url.Action("GetRolesByAutoComplete","Roles")',
{
data: {
'q': qry,
'key': document.getElementById('CompanyCode').value
}
}
).done(function (res) {
callback(res)
});
}
}
});
$('#BossName').on('autocomplete.select', function (evt, item) {
console.log(item);
$('#BossID').val(item.value);
$('#BossName').val(item.text);
});

</div>
</div>

You send data to the server, but when it fails you replace modal contents.
Replacing HTML destroys everything that was already there, so you wipe everything that was done by your autocomplete plugin.
All you need to do is to initialize autocomplete again:
success: function (redata) {
if (redata.status === "success") {
} else {
var newBody = $('.modal-body', redata);
var newFoot = $('.modal-footer', redata);
PlaceHolderElement.find('.modal-body').replaceWith(newBody);
PlaceHolderElement.find('.modal-footer').replaceWith(newFoot);
// INITIALIZE AUTOCOMPLETE HERE
}
},

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">

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:

AntiforgeryToken generation from using #Ajax.BeginForm()

I have an issue in generating anti-forgery token manually inside ajax methods. So my question If I used ajax.beginform(), does it generate a token like the #html.beginform? If so, how can I use it with my ajax methods?
Kindly ignore the long code in the view. My main concern is with the ajax methods. I posted it to show you the view in case of the suggestion of using the beginForm().

Here's an example of Ajax.BeginForm from one of my views:
<!-- FORM Atributo -->
#using (Ajax.BeginForm(accionFormulario, "Atributos", new AjaxOptions() { OnSuccess = "onSuccessCreate" }, new { #id = "frmCreate" }))
{
#Html.AntiForgeryToken()
#Html.HiddenFor(model => model.AtributoId)
#Html.HiddenFor(model => model.EmpresaId)
<div class="modal-body">
<div class="row">
// the form inputs ....
</div>
</div>
<div class="modal-footer">
<button class="btn btn-secondary mx-1" type="button" data-dismiss="modal" aria-label="Close">#Global.Cancelar</button>
<button class="btn btn-primary" type="submit"><strong>#Global.Guardar</strong></button>
</div>
}
This generates the AntiForgeryToken as expected:
You can capture it with javascript as you were doing in your view.

Laravel upload image through modal not working

Im making an inventory system in laravel and I want to upload an image every products that I have. My problem is I cant upload an image. I tried my old code in uploading photo and it is not working in my current project. The upload code you see in the controller is in a laravel collective form. But now, I am using a modal and an ajax request to save the inputs into the database. Can someone know what should I do about this? Btw, my modal doesnt have a form tag because I thought forms will not work in modals. Thanks in advance!
Modal Create.

I Can’t add a comment, that is dumb ...
Your also going to likely need to encode the image data in the json.
See How do you put an image file in a json object?

How to submit form in jquery

This maybe a simple problem, but I can't find the cure.
When I executes this :-
$('#save_results').on("click", function () {
$('#formSaveQuotationPrepDetail').submit();
});
Everything works fine. But when I do this :-
$('#save_results').on("click", function () {
$('#formSaveQuotationPrepDetail').submit(function (e) {
var result = '#TempData["StatusMsg"]';
e.preventDefault();
if (result == 'Success') {
alert("Saved Successfully.");
}
})
});
This is my code behind :-
[HttpPost]
public ActionResult SaveQuotePreparation(QuotationPreparationEntity quoteP)
{
string result = objManager.SaveQuotePreparation(quoteP);
if (!string.IsNullOrEmpty(result) && (result == GeneralConstants.Inserted || result == GeneralConstants.Updated))
{
//Payment Gateway
data = GeneralConstants.SavedSuccess;
TempData["StatusMsg"] = "Success";
}
return new JsonResult { Data = data, JsonRequestBehavior = JsonRequestBehavior.AllowGet };
}
My HTML is a long code , I've made it short just for understanding :-
#using (Html.BeginForm("SaveQuotePreparation", "Technical", FormMethod.Post, new { #id = "formSaveQuotationPrepDetail" }))
{
<div class="row">
<form>
<div class="col-md-12 text-left">
<div class="row text-center">
<div class="col-md-4">
<div class="form-group text-left">
<label class="control-label ">
Quote Number
</label>
#Html.DropDownListFor(m => m.QuoteNo, new SelectList(#ViewBag.ListQuoteNo, "DataStringValueField", "DataTextField", Model.QuoteNo),
new
{
#class = "form-control requiredValidation",
#id = "QuoteNo",
#data_inneraction = "validationCall",
#onfocusout = "return ValidateRequiredFieldsOnFocusOut(this)"
})
<span class="HideValidMsg">Please Select QuoteNo</span>
</div>
</div>
<div class="col-md-4">
<div class="form-group text-left">
<label class="control-label">
Product Line
</label>
#Html.DropDownListFor(m => m.ProductLine, new SelectList(#ViewBag.ListProdGrp, "DataStringValueField", "DataTextField", Model.ProductLine),
new
{
#class = "form-control requiredValidation",
#id = "ProductLine",
#onfocusout = "return ValidateRequiredFieldsOnFocusOut(this)",
ng_model = "ProductLine",
ng_change = "GetProductLineDetails(ProductLine)"
})
<span class="HideValidMsg">Please Select ProductLine</span>
</div>
</div>
</div>
</div>
<div class="row">
<div class="col-md-12 pt-4 text-center">
<button type="button" class="btn btn-success btn-sm" data-dismiss="modal" id="save_results">Save</button>
#*<input style="font-size:18px" type="button" class="btn btn-success btn-sm" data-dismiss="modal" id="save_results" value="Save" />*#
<input style="font-size:18px" type="button" class="btn btn-secondary btn-sm" data-dismiss="modal" value="Close" />
</div>
</div>
</form>
The Event don't fire on click. I don't get any error or anything.
I want to return JSON data on submit and show it as an alert on the screen.

You can do form submit in javascript like this..
$(document).on("submit", "form", function (event) {
event.preventDefault();
$.ajax({
url: $(this).attr("action"),
type: $(this).attr("method"),
dataType: "JSON",
data: new FormData(this),
processData: false,
contentType: false,
success: function (data, status) {
successFunction()
}
},
error: function (xhr, desc, err) {
}
});
});
The From will define like this
<form class="form-horizontal" id="frm" name="frm" action="/Controler/Action" method="post" enctype="multipart/form-data"></form>
And Need to create the button as submit
<input type="submit"/>

i dont have your html code but ,
if you want your form to be submitted by on click event :
$('#save_results').on("click", function () {
e.preventDefault();
$('#formSaveQuotationPrepDetail').submit();
if (result == 'Success') {
alert("Saved Successfully.");
}
});
take a look at this example to see difference between your first and second code .
NOTE : in your code result is not defined , i am not sure where have you brought it from

You did mistake in view page. Please remove <form> tag inside view page. It will work.
You only use below code instead of your code:
note: Html.Beginform() method work as tag in HTML
#using (Html.BeginForm("SaveQuotePreparation", "Technical", FormMethod.Post, new { #id = "formSaveQuotationPrepDetail" }))
{
<div class="row">
<div class="col-md-12 text-left">
<div class="row text-center">
<div class="col-md-4">
<div class="form-group text-left">
<label class="control-label ">
Quote Number
</label>
#Html.DropDownListFor(m => m.QuoteNo, new SelectList(#ViewBag.ListQuoteNo, "DataStringValueField", "DataTextField", Model.QuoteNo), new { #class = "form-control requiredValidation", #id = "QuoteNo", #data_inneraction = "validationCall", #onfocusout = "return ValidateRequiredFieldsOnFocusOut(this)" })
<span class="HideValidMsg">Please Select QuoteNo</span>
</div>
</div>
<div class="col-md-4">
<div class="form-group text-left">
<label class="control-label">
Product Line
</label>

<span class="HideValidMsg">Please Select ProductLine</span>
</div>
</div>
</div>
</div>
<div class="row">
