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');
});
});
});

Javascript function undefined, but IT IS

I'm doing some testing with AJAX form submissions and I keep getting ReferenceError: submit_ajax is not defined from the code below. However, you can see that it IS defined.
<script type="javascript">
function submit_ajax(){
data = {'email':$('#email2').val(),'password':$('#pwd2').val()}
$.ajax({
url: 'ajax_testing.php',
data: data,
success: function() {
//AJAX success
$('#success_fail').html('success!');
window.setTimeout(function() { $('#success_fail').hide(); }, 3000);
$('#myModal2').hide();
},
error: function() {
//Ajax failure
$('#success_fail').html('failed!');
window.setTimeout(function() { $('#success_fail').hide(); }, 3000);
$('#myModal2').hide();
}
});
}
</script>
<div>
<div id="success_fail"></div>
<!-- Trigger the modal with a button -->
<button type="button" class="btn btn-info btn-lg" id="button_for_modal2" data-toggle="modal" data-target="#myModal2">Form Submitted via AJAX and No Parent Refresh</button>
<!-- Modal -->
<div class="modal fade" id="myModal2" 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">Title of Form</h4>
</div>
<div class="modal-body">
<h2>Vertical (basic) form</h2>
<!--<form action="<?PHP echo $_SERVER['PHP_SELF']; ?>" method="post">*******************************AJAX*********************************-->
<div class="form-group">
<label for="email">Email:</label>
<input type="email" class="form-control" id="email2" placeholder="Enter email (ajax)" name="email2">
</div>
<div class="form-group">
<label for="pwd">Password:</label>
<input type="password" class="form-control" id="pwd2" placeholder="Enter password (ajax)" name="pwd2">
</div>
<button onclick="submit_ajax()" class="btn btn-default">Submit</button>
<!--</form>-->
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
</div>
I've tried running the function directly in the console and I get the same thing.
Any idea about what's going wrong here?

Instead of using <script type="javascript"> use <script type="text/javascript"> which is valid type for JS code.

change your script tag, either dont include type or set it as type="text/javascript"
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script type="text/javascript">
function submit_ajax(){
alert('submit_ajax working')
data = {'email':$('#email2').val(),'password':$('#pwd2').val()}
$.ajax({
url: 'ajax_testing.php',
data: data,
success: function() {
//AJAX success
$('#success_fail').html('success!');
window.setTimeout(function() { $('#success_fail').hide(); }, 3000);
$('#myModal2').hide();
},
error: function() {
//Ajax failure
$('#success_fail').html('failed!');
window.setTimeout(function() { $('#success_fail').hide(); }, 3000);
$('#myModal2').hide();
}
});
}
</script>
<button onclick="submit_ajax()" class="btn btn-default">Submit</button>

Save Signature when Form is Submitted

I'm using the jSignature plugin to add signature capture to a simple Bootstrap modal window - the signature capture displays correctly and I can draw and save the signature without any issues. Here's a screenshot showing the signature modal window in action:
At present the user must enter their signature then click the Save button below the signature for it to be saved. They then have to click the Submit button to submit the form which updates a database etc.
Here's the html code for the modal window:
<div class="modal" id="myModal">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal"><span aria-hidden="true">×</span><span class="sr-only">Close</span></button>
<h4 class="modal-title">Approver Signature</h4>
</div>
<div class="modal-body">
<form id="saveEvent" action="update.php" method="post">
<div class="form-group">
<input type="hidden" name="id" value="123456">
<input type="hidden" id="hiddenSigData" name="hiddenSigData" />
<label for="yourName">Approver Name</label>
<input type="text" class="form-control" id="managerName" name="managerName" placeholder="Manager's Name" value="Peter Rabbit">
<label for="managerNotes">Approver Notes</label>
<input type="text" class="form-control" id="managerNotes" name="managerNotes" placeholder="Manager's Notes" value="">
</div>
<div class="form-group">
<label for="yourSignature">Approver Signature</label>
<div id="signature"></div>
<button type="button" class="btn btn-default" onclick="$('#signature').jSignature('clear')">Clear</button>
<button type="button" class="btn btn-primary" id="btnSave">Save</button>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button>
<button type="submit" class="btn btn-success">Submit</button>
</div>
</form>
</div>
<!-- /.modal-content -->
</div>
<!-- /.modal-dialog -->
</div>
<!-- /.modal -->
We have found them many users are forgetting to click the Save button to first save the signature and simply clicking the Submit button which submits the form but doesn't include the signature, and by the time we notice it's too late to get the signature again.
Here's the Javascript that runs when the signature Save button is clicked:
$(document).ready(function() {
$('#btnSave').click(function() {
var sigData = $('#signature').jSignature('getData', 'default');
$('#hiddenSigData').val(sigData);
console.log('jSignature saving signature');
});
})
We're looking for a way, when the Submit button is pressed, to automatically save the signature first and then submit the form. Not sure if this is possible or how to achieve this?

You can use an event handler.
$("#saveEvent").submit(function(){
var sigData = $('#signature').jSignature('getData', 'default');
$('#hiddenSigData').val(sigData);
console.log('jSignature saving signature');
});
You're done!

onclick returns function is not defined

I've a Bootstrap modal for changing a user's password. The problem, however, is that no matter what I try I cannot get the event to fire, be it via onclick or by attaching the button to an event using .on. It simply will not recognise it.
I've tried putting the <script> tags above the modal, below the modal, and even inside the modal, only to always have onclick return Uncaught ReferenceError: updatePassword is not defined. I then removed the onclick, assigned an ID to the submit button, and tried $('#update-password').on('click', function() { ... }); but this wasn't recognised at all.
The culprit in all of this is almost definitely the Bootstrap modal, and I'm guessing it's got something to do with how the browser handles it upon page load.

My apologies if this has been asked before. The only questions I could seem to find were those asking how to launch a modal through onclick.

The problem is that your event is not getting binded with button
Please find the JSFIDDLE here
In your HTML - do the following in the script tag
<head>
<script>
function updatePassword(){
console.log('updatePassword');
}
$(document).ready(function(){
// $('.btn-primary').on('click',function(){ - This too works
// console.log('foo');
//});
$('.btn-primary').on('click',updatePassword);
});
</script>
</head>

form inside modal won't submit with jQuery

I have a form inside a bootstrap modal that I want to submit via an Ajax request. I've followed along closely with this post. For some reason, I can't get the form to actually submit. Here's the HTML for my modal.
<div id="modal-close" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="modal1" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h3 id="myModalLabel">Edit Introduction</h3>
</div>
<div class="modal-body">
<form id="modal-form-close" method="post">
<input type="hidden" name="event_timestamp" value="{{event.timestamp}}">
<input type="hidden" name="event_desc" value="{{event.desc}}">
<input type="hidden" name="status" value="closed">
<input type="text" name="resolution" value="">
</form>
</div>
<div class="modal-footer">
<button class="btn" data-dismiss="modal" aria-hidden="true">Close</button>
<button class="btn btn-primary" data-dismiss="modal" id="modal-close-submit">Save changes</button>
</div>
</div>
</div>
</div>
And here's my JavaScript:
<script>
$(function(){
$('#modal-form-close').on('submit', function(e){
e.preventDefault();
$.ajax({
url: '/events/edit/{{event.event_id}}/script',
data: $('#modal-form-close').serialize(),
type: 'POST',
success: function(data){
alert('successfully submitted')},
error: function(data){
alert('something went wrong')
}
});
});
});
</script>
With the javascript written this way, nothing ever happens when I press submit the form. However, if I change the function to .on('click'), things work as expected. What am I missing?

Found the answer here.
I needed to wire the "click" action back to the submit button.
$('button#submit').on('click', function(e){
And add an id=submit to the submit button
<button id="submit" class="btn btn-primary" data-dismiss="modal">Save changes</button>
It's amazing how far you can get copy-pasting code from stack overflow.

Try to add this type in your button
<button type="submit" class="btn btn-primary" data-dismiss="modal" id="modal-close-submit">Save changes</button>

I do this:
give a form an ID <form id="submit_modal">
make a button type="button" and tells him what to do when click onClick="document.getElementById('submit_modal').submit();". So the submit button will looks like this :
<button type="button" class="btn btn-primary" onClick="document.getElementById('submit_modal').submit();">Submit</button>
