Jquery load whole page instead of only modal

I'm trying to make a "Create project" modal. At first i created it inside a partial view but i found it difficult to populate it with data from other models, so instead i decided to move the partial view content inside my actual razor page.
All works as it should but when I press the button to launch the modal, the current page is loaded in the background as well.
Here is the html for the modal code:
<div class="modal fade" id="add-project" tabindex="-1" role="dialog" aria-labelledby="addProjectLabel" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="addContactLabel">Create Project</h5>
</div>
<div class="modal-body">
<form asp-page-handler="ProjectModalPartial">
#*numele metodei*#
<input name="IsValid" type="hidden" value="#ViewData.ModelState.IsValid.ToString()" />
<div class="form-group">
<label asp-for="ProjectsModel.ProjectName">Title</label>
<input asp-for="ProjectsModel.ProjectName" class="form-control" placeholder="MyProject1" />
<span asp-validation-for="ProjectsModel.ProjectName" class="text-danger"></span>
</div>
<br />
<div class="form-group">
<label asp-for="ProjectsModel.ProjectDescription">Description</label>
<textarea asp-for="ProjectsModel.ProjectDescription" class="form-control" rows="3" placeholder="This is my first project"></textarea>
<span asp-validation-for="ProjectsModel.ProjectDescription" class="text-danger"></span>
</div>
<br />
<div class="center" style="padding-bottom:0px;">
<p style=" margin: 2px">Project Participants</p>
<select multiple id="TicketType" class="form-control dropdown-toggle" asp-for="ProjectsModel.ProjectParticipants" asp-items="new SelectList(Model.UserList)" style="width: 470px;"></select>
</div>
</form>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary" data-save="modal">Save</button>
</div>
</div>
</div>
And here is the jquery code,without the logic for saving:
$(function () {
var placeholderElement = $('#modal-placeholder');
$('button[data-toggle="ajax-modal"]').click(function (event) {
var url = $(this).data('url');
$.get(url).done(function (data) {
//$(document.body).html(data).find('.modal').modal('show');
placeholderElement.html(data);
placeholderElement.find('.modal').modal('show');
});
});});
Is there another way of loading the modal, without the additional content?
Here is a photo so you better see what's happening

I managed to solve the problem.
Since I no longer have a partial view I don't need the placeholderElement anymore, so I can get rid of .find(modal) all together.
The code now looks like this:
$(function() {
var placeholderElement = $('#modal-placeholder');
$('button[data-toggle="ajax-modal"]').click(function(event) {
var url = $(this).data('url');
$.get(url).done(function (data) {
$('#add-project').modal('show');
});
});
});

Modal doesn't close on Save operation

I am following this guide (https://softdevpractice.com/blog/asp-net-core-mvc-ajax-modals/) for my Modals, and got everything working except for the last part which closes the Modal when it saves without errors. Essentially what the article shows is to add an IsValid input tag that's hidden and stores the ModelState which would be used to determine whether or not it is a successful save and should close the modal.
// find IsValid input field and check it's value
// if it's valid then hide modal window
var isValid = newBody.find('[name="IsValid"]').val() == 'True';
if (isValid) {
placeholderElement.find('.modal').modal('hide');
}
Would love any input on this. My code is as follows:
View
<div id="AddStudyModal"></div>
// unrelated code here
<button type="button" class="btn btn-secondary" data-toggle="ajax-modal" data-bs-target="#add-study" data-url="#Url.Action("AddStudy", "App", new {id = Model.GUID})">Add</button>
Partial View
#model AddStudyViewModel
<div class="modal fade" id="add-study" tabindex="-1" role="dialog" aria-labelledby="addStudyLabel" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">

Site.Js
$(function (){
var AddStudyElement = $('#AddStudyModal');
$('button[data-toggle="ajax-modal"]').click(function(event){
var url = $(this).data('url');
$.get(url).done(function(data){
AddStudyElement.html(data);
AddStudyElement.find('.modal').modal('show');
})
})
AddStudyElement.on('click', '[data-save="modal"]', function(event){
event.preventDefault();
var form = $(this).parents('.modal').find('form');
var actionUrl = form.attr('action');
var sendData = form.serialize();
// $.post(actionUrl, sendData).done(function(data){
// AddStudyElement.find('.modal').modal('hide');
// })
$.post(actionUrl, sendData).done(function (data) {
var newBody = $('.modal-body', data);
AddStudyElement.find('.modal-body').replaceWith(newBody);
// find IsValid input field and check it's value
// if it's valid then hide modal window
var isValid = newBody.find('[name="IsValid"]').val() == 'True';
if (isValid) {
AddStudyElement.find('.modal').modal('hide');
}
});
});
});
Edit: After more examination it seems like my issue may be related to my RedirectToAction. I have posted my controller action below
[HttpPost]
public IActionResult Study(StudyViewModel model)
{
if (ModelState.IsValid)
{
var response= _repo.AddEditStudy(model.StudyGuid,model.SelectedStudyCatalogGuid, model.ParticipantGuid, model.StartDate, model.EndDate);
if (response.Success)
{
TempData["Message"] = response.Message;
return RedirectToAction("EditParticipant", new {id = model.ParticipantGuid});
}
}
model.Studies = GetStudyCatalog();
return PartialView("_StudyModal", model);
}

FormControlName not showing the previous values in angular 7 material modal

I want this modal to have the existing values of the field. I can be done through formControlName. But it is not happening.I click on the edit button and on that click function , i assign the values before opening the edit Modal. However, they don't fill the text boxes in the modal. In console it appears before i click the modal button. Please help
app.component.ts
openEditModal(taskIdValue:number){
console.log("Task Id Value = ", taskIdValue)
for(var i = 0 ; i<this.result.length ; i++){
if(this.result[i].taskId == taskIdValue ){
console.log("this.result[i] = ", this.result[i])
localStorage.setItem('editTaskId',this.result[i].taskId);
localStorage.setItem('editTaskName',this.result[i]. taskName);
}
}
this.editTaskId = localStorage.getItem('editTaskId')
this.editTaskName = localStorage.getItem('editTaskName')
$('#editModal').click();
this.displayEdit = true;
}
editTask(){
console.log("this.result.taskId", )

You'd better use [(ngModel)] with your object maybe, your typescript code is not clear enough with the way you build editTaskForm, so I suggest to organize the code clearly, and step by step, you will get it working.
Greetz!

you can set the previous value by using this.formGroupname.patchValue({}), For example
this.form.patchValue({ fullname1: this.fullname1, });

hide/show popup on ajax request using php

I am trying to make a submit using ajax but I'm facing issues, I'm having two popup one is #popup-subscribe and the other is #popup-subscribe-success, I wanted to hide the first popup on subscribe and show the second popup.
This is how I open the first popup:
<button class="btn btn-round btn-primary mt-1 w-100" data-toggle="popup" data-target="#popup-subscribe">Subscribe Now</button>
The first popup is:
<!-- Subscribe PopUp -->
<div id="popup-subscribe" class="popup col-10 col-md-4 p-6" data-animation="slide-up">
<button type="button" class="close" data-dismiss="popup" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
<form action="#" method="post" name="form-subscribe" id="form-subscribe">
<h5>Stay Updated</h5>
<p>Latest news direct to your inbox — <mark>no spams</mark>.</p>
<div class="form-group">
<input class="form-control" type="text" name="full_name" placeholder="Your Full Name">
</div>
<div class="form-group">
<input class="form-control" type="email" name="email_id" placeholder="Your Email Address">
</div>
<div class="form-group">
<input class="form-control" type="text" name="cell_no" placeholder="Your Cell Number">
</div>
<button class="btn btn-lg btn-block btn-primary" type="submit">Subscribe</button>
</form>
</div>
and the second popup is:
<!-- Subscribe Success -->
<div id="popup-subscribe-success" class="popup col-10 col-md-4 p-6" data-animation="slide-up">
<button type="button" class="close" data-dismiss="popup" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
<h5>Stay Updated</h5>
<p id="subscriber_ip"></p>
<p>Latest news direct to your inbox — <mark>no spams</mark>.</p>
</div>
and the script I'm using is:
//form-subscription-submit-action
$("#form-subscribe").submit(function(e) {
e.preventDefault();
$.ajax({
type: "POST",
url: "assets/php/ajax_functions.php",
data: $(this).serialize()+"&action=form-subscribe",
dataType: "json",
success: function(data){
if(data.status==1) {
$("#popup-subscribe").hide();
//$("#popup-subscribe-success").find("#subscriber_ip").html(data.subscriber_ip)
$("#popup-subscribe-success").show();
}
}
});
});
the first popup is getting hidden but the second popup is not getting visible.

Show modal on submit form

Here's the code of an Angular 4 component used to collect contact information from visitors:
.html:
<form (submit)="onCreateContact()">
<div class="form-group">
<input type="text" [(ngModel)]="contactname" name="contactname" class="form-control form-control-lg" placeholder="Name">
</div>
<div class="form-group">
<input type="email" [(ngModel)]="contactemail" name="contactemail" class="form-control form-control-lg" placeholder="Email">
</div>
<div class="form-group">
<input type="text" [(ngModel)]="contactphone" name="contactphone" class="form-control form-control-lg" placeholder="Phone">
</div>
<input type="submit" class="btn btn-outline-light btn-block" data-toggle="modal" data-target='#addContactModal'>
</form>
<!-- Modal -->
<div class="modal fade" id="addContactModal" tabindex="-1" role="dialog" aria-labelledby="addContactModalLabel" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="addContactModalLabel">Contact</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
Thanks for contacting us! We will get in touch with you shortly.
</div>
<div class="modal-footer">
<button type="button" class="btn btn-primary" data-dismiss="modal">OK</button>
</div>
</div>
</div>
</div>
.ts:
onCreateContact() {
let contact = {
contactname: this.contactname,
contactemail: this.contactemail,
contactphone: this.contactphone
}
return this.http.post('api/contacts/add', contact).map(res => res.json()).subscribe(data => {
if(data.success) {
console.log(data);
} else {
console.log('Failed to add contact');
}
}
);
}
All contact fields are required; the data is not passed to the backend if not all fields are filled.
Currently, the Bootstrap modal popups every time I press the submit button, even when the data is not passed. How can I show it only when the data is actually passed to the server?

You are toggling the modal when the user clicks on the submit button.
What you need to do is, toggle the modal from component class(.ts) after getting the response from the backend.
So in your ".ts" file add below line under the imports section
declare var $: any;
Then toggle modal after receiving response from backend as below
onCreateContact() {
return this.http.post('api/contacts/add', contact).map(res => res.json()).subscribe(data => {
if(data.success) {
console.log(data);
$('#addContactModal').modal('show'); // Add this line
} else {
console.log('Failed to add contact');
$('#errorModalId').modal('show'); // If you are planning to show error modal when something goes wrong.
}
});
}
Don't forget to remove data-toggle and data-target attribute from submit button.
Hope this helps.
