How to pass a parameter to a modal form using Ajax

I have a razor page that displays a list of expenses for the Report selected. I have an "Add Expense" button on the page that brings up a modal. The modal is a partial View of the form. What i need to do is pass the ExpenseId to the modal. I can get the Id from the url like this
#{ var expenseId = Request.Url.Segments[3]; }
the button currently looks like this
<button type="button" data-toggle="modal" data-target="#expenseModal_#expenseId" data-id="#expenseId" class="btn btn-primary" id="addExpenses">
Add Expense
</button>
There are a few things in this that i do not know if i even need them. I was trying different things.
Modal
<!-- MODAL -->
<div class="modal fade" id="expenseModal_#expenseId" tabindex="-1" role="dialog" aria-labelledby="expenseModalLabel" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h4 class="modal-title" id="expenseModalLabel"> Expences </h4>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div> <!-- MODEL HEADER-->
<div class="modal-body">
</div> <!-- MODAL BODY-->
</div>
</div>
Javascript
<script type="text/javascript">
$(document).ready(function () {
$("#addExpenses").click(function () {
$(".modal-body").html('');
$.ajax({
type: 'GET',
url: '#Url.Action("_ExpenseForm", "Admin")',
data: { type: $(this).attr("data-type") },
success: function (response) {
$(".modal-body").html(response);
$("#expenseModal").modal('show');
},
error: function () {
alert("Something went wrong");
}
});
});
});
</script>
The expense Id has to be inserted in the form so that when it is saved it saves it to the correct Expense report.
Controller actions
ExpensesDataAcessLayer objexpense = new ExpensesDataAcessLayer();
public ActionResult ExpenseReports()
{
return View(db.ExpenseReports.ToList());
}
public ActionResult Expenses(int ExpenseId)
{
return View(db.Expenses.Where(x => x.ExpenseId == ExpenseId).ToList());
}
public ActionResult _ExpenseForm()
{
CustomerEntities customerEntities = new CustomerEntities();
List<SelectListItem> categoryItem = new List<SelectListItem>();
ExpensesViewModel casModel = new ExpensesViewModel();
List<ExpenseTypes> expensetypes = customerEntities.ExpenseType.ToList();
expensetypes.ForEach(x =>
{
categoryItem.Add(new SelectListItem { Text = x.CategoryItem, Value = x.ItemCategoryId.ToString() });
});
casModel.ExpenseTypes = categoryItem;
return View(casModel);
}
Thanks for your help!

You can store expenseId into hidden field, like this
<input id="expenseId" name="expenseId" type="hidden" value="#Request.Url.Segments[3]">
Then you can get like this
$("#addExpenses").click(function () {
var expenseId = $("#expenseId").val();
// after code here
Updated
You can get expenseId like this
var expenseId = $(this).attr("data-id")
Then you can assign it to hidden field or anywhere in Model, Like this
<!-adding aditional input into HTML in MODEL-!>
<input id="expenseId" name="expenseId" type="hidden" value="">
<!- Javascript-!>
var expenseId = $(this).attr("data-id")
expenseId.val(expenseId );

modal iteration in foreach loop using ajax

I got a problem with foreach loop. What am i trying to do is get data (JsonResult) from action in controller. Get get songs for each album.
public JsonResult SongListByAlbum(int albumID)
{
var songs = (from song in Song.GetSongList()
join album in Album.GetAlbumList()
on song.AlbumID equals album.AlbumID
where (albumID == album.AlbumID)
select song).ToList();
return Json(songs,JsonRequestBehavior.AllowGet);
}
Then put them into view, for album get list of songs and show them as modals
There is my view:
#foreach (var item in Model.Albums){
<button id="#item.AlbumID" type="button" class="btn btn-primary myModals" data-toggle="modal" data-target="#exampleModal-#item.AlbumID">
Show
</button>
<!-- Modal -->
<div class="modal fade" id="exampleModal-#item.AlbumID" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel-#item.AlbumID" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLabel-#item.AlbumID">#item.AlbumName #item.Year, #item.BandName</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div id="parent" class="modal-body">
</div>
<div class="modal-footer">
<button id="closeModal"type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
}
And there is a script, where I get songs for each album.
<script>
$(".myModals").on("click", function () {
var Id = $(this).attr('id');
alert(Id);
$.ajax({
type: "GET",
url: '#Url.RouteUrl(new{ action= "SongListByAlbum", controller="Default"})',
data: {albumID:Id},
contentType: "application/json;charset=utf-8",
dataType: "json",
success: function (result) {
for (var i in result) {
$('#parent').append('<p class="toRemove">' + result[i].SongName + '</p>');
}
},
error: function (response) {
alert('error');
}
});
});
</script>
The problem is : when i click on the first modal button everything is fine, i get what i want to. But when i click on the second one i got empty modal. Then when i click again on the first one i got data from previous click and penultimate. Image: enter image description here

To avoid multiple <div id="parent"> elements, you should probably assign the Id the same way you do for the buttons. Like <div id="parent-#item.AlbumID">. Then in your ajax call reference the correct div. $('#parent-' + Id).
Not sure if that is your only probably, but might get you closer.

How to popup(open) a bootstrap modal on ajax success

I have a JSP page,say xyz.jsp. I have a button called "send Mail" that has it's onclick() property set to a script function called sendMail(). Sending mail includes sending html data to the controller for generating PDF for which I am using Ajax. Now after the mail is sent successfully ,i want to show a pop-up indicating success. So on Ajax success i want to trigger the popup.
I am using bootstrap modal for popup.
This is my code for button and modal:
<div id="reportbuttons">
<button type="button" class="btn bg-red waves-effect" onclick="convertToPdf()" style="margin-right: 5px;float: right; margin-top: -8px">Download</button>
<button type="button" class="btn bg-red waves-effect" onclick="sendMail()" style="margin-right: 5px;float: right; margin-top: -8px">Send Mail</button>
<!-- Modal -->
<div class="modal fade" id="myModal" role="dialog">
<div class="modal-dialog">
<!-- Modal content-->
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-
dismiss="modal">×</button>
<h4 class="modal-title">Modal Header</h4>
</div>
<div class="modal-body">
<p>Some text in the modal.</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data
dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
</div>
And, this is my script:
<script>
function sendMail() {
let doc = new jsPDF('p','pt','a4');
doc.setProperties({
title: 'PDF Document',
subject: 'subject',
author: 'ABC',
keywords: 'generated, javascript, web 2.0, ajax',
creator: 'XYZ'
});
//document.getElementById('reportbuttons').remove();
document.getElementById('reportbuttons').style.display ="none";
doc.addHTML(document.body, function() {
var data = doc.output('datauristring');
var reqJson = {};
reqJson.machineId = "<%=machineId%>";
reqJson.monthYear = "<%=monthYear%>";
reqJson.data = data;
$.ajax(
{
url : "sendMail/",
type: "POST",
dataType: 'json',
data : JSON.stringify(reqJson),
contentType: "application/json",
success:function(data)
{
$("#myModal").modal();
alert('mail sent successfully');
document.getElementById('reportbuttons').style.display ="block";
},
error: function(data)
{
document.getElementById('reportbuttons').style.display ="block";
}
});
});
}
</script>
I want to show the bootstrap modal popup after the mail is succesfully sent or in other words on Ajax success.

Why is the delete button on my application not working?

I made a delete button that's supposed to delete some entries from a model, but i keep getting an error that i'm not sure how to solve, I have a controller that has an IActionresult named deletelname, and everything seems logical but i just don't know why it's not working. If someone could look at the code and give me some feed back i would appreciate it very much.
The view:
#model IEnumerable<Models.pinfo>
#using Models
#foreach (var s in Model){
<h1> #s.fname #s.lname </h1> <h3> #s.comment </h3> <a class="GoDelete" href="javascript:void(0)" data-id="#s.lname">Delete</a>
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button>
<h4 class="modal-title" id="myModalLabel">Deleting....</h4>
</div>
<div class="modal-body">
Are you sure to Delete this Course?
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button id="btndelete" type="button" class="btn btn-primary">Delete</button>
</div>
</div>
</div>
</div>
}
#section scripts
{
<script>
$(document).ready(function() {
$("#btndelete").click(function () {
$('#myModal').modal('hide');
var id = $('#hfId').val();
window.location.href = '#Url.Action("deletelname","Home")/'+id;
});
$(".GoDelete").click(function () {
var id = $(this).attr("data-id");
$('#hfId').val(id);
$('#myModal').modal('show');
});
});
</script>
}
the Controller piece:
public IActionResult deletelname(pinfo pinfo)
{
var fsname = db.pinfo;
var lsname = db.pinfo;
var csomment = db.pinfo;
foreach (var fname in fsname)
{
db.Remove(fname);
}
foreach (var lname in lsname){
db.Remove(lname);
}
return View("Contact", "Home");
}
here is the error i get when i press the delete button:

The error message is because you are passing the string "Home" as the model for the view "Contact". The view is expecting an enumerable object of type Model.pinfo
try passing the pinfo object back out of the controller when rendering the view. I'm not sure that will do what you want but it seems to be what you are looking for.
public IActionResult deletelname(pinfo pinfo)
{
var fsname = db.pinfo;
var lsname = db.pinfo;
var csomment = db.pinfo;
foreach (var fname in fsname)
{
db.Remove(fname);
}
foreach (var lname in lsname){
db.Remove(lname);
}
return Contact();
}
Javascript is not correct either
$("#btndelete").click(function () {
$.ajax({
url: '#Url.Action("deletelname","Home")',
method: 'POST',
data: { pinfo: $('#hfId').val() },
success: function (response) {
// this code gets run after the request is successful
// based on the controller method that we have written, the response
// should be all of the "Contact" view html re-rendered.
console.log(response);
//if there is an error you will probably not want to close the modal
// so only close if it is successful
$('#myModal').modal('hide');
},
error: function (response) {
//runs if there is an error
console.log(response);
}
});
});
