Close Bootstrap Modal from within injected HTML?

Script to Call Modal, and HTML Skeleton for Modal: (which is working)
<script>
$(document).on("click", ".addworker", function (e) {
e.preventDefault();
var $popup = $("#popup");
var popup_url = $(this).data("popup-url");
$(".modal-content", $popup).load(popup_url, function () {
$popup.modal("show");
});
});
</script>
<div id="popup" class="modal fade" role="dialog">
<div class="modal-dialog modal-lg">
<div class="modal-content">
</div>
</div>
</div>
The HTML loaded into modal-content is returned by a django view which sits behind the url. (this part is working too)
Inside this HTML i have the Button, which i want to use to then close the modal again.
But when the Modal got injected with the HTML and is open, it seems like the modal is out of scope, so i tried to get it back with var $popup = $("#popup");.
And i indeed get back the Object, but the $popup.modal("hide"); Method doesnt work.
<script>
$(document).on("click", ".cancel", function (e) {
var $popup = $("#popup");
$popup.modal("hide");
});
</script>
<div class="modal-header">
<h1>{{ aoe }} Worker: {{ id }}</h1>
</div>
<form action="add/" method="post">
{% csrf_token %}
<div class="modal-body">
{{ form|crispy }}
</div>
<div class="modal-footer">
<input type="button" class="btn btn-secondary cancel" value="Cancel">
<input type="submit" class="btn btn-primary" value="Submit">
</div>
</form>
My first workaround: (inside the html file that gets injected to the modal)
<script>
$(document).on("click", ".cancel", function (e) {
var $popup = document.querySelector('#popup');
$popup.classList.remove('show');
$('#popup').css("display", "none");
var $back = document.querySelector('.modal-backdrop');
$back.parentNode.removeChild($back);
});
</script>
This works, but is not really that convenient.
Second Workaround:
Just call $("#popup").click() when pressing the Close Button,
to simulate a click into the free area next to the Modal.
Feels like cheating, but at least its less effort now.
Still, i would like to know the "proper" way to do this.

Problem Solved. I included JQuery in Both HTML Files, which seemed to cause the function not to work anymore. Now it works using $("#popup").modal('hide');

Materialize modal not working

I wrote a simple code for materialize modal.
HTML code:
<a class="waves-effect waves-light btn view" data-target="modal1">View Scores</a>
<!-- Modal Structure -->
<div id="modal1" class="modal">
<div class="modal-content">
<h4>Modal Header</h4>
<p>A bunch of text</p>
</div>
<div class="modal-footer">
Agree
</div>
</div>
JS code:
$(document).ready(function() {
// the "href" attribute of .modal-trigger must specify the modal ID that wants to be triggered
/*$('.view').click(function (){
$('#modal1').modal('open');
alert('edskjcxnm');
});*/
/*$('.view').leanModal();*/
$('#modal1').modal('open');
});
JSFiddle link: https://jsfiddle.net/7f6hmgcf/
Why isn't it working?

Initialize all modals first. $('.modal').modal();
Complete code will look like this
(function ($) {
$(function () {
//initialize all modals
$('.modal').modal();
//now you can open modal from code
$('#modal1').modal('open');
//or by click on trigger
$('.trigger-modal').modal();
}); // end of document ready
})(jQuery); // end of jQuery name space

Not 100% sure what you are asking for here, but if what you are asking is how to trigger modal on button click you can simply do it by setting an onclick like this:
<a class="waves-effect waves-light btn view" onclick="$('#modal1').modal('open');">View Scores</a>
But before you can do $('#modal1').modal('open'); you need to initiate the modal in your js, like this:
$(document).ready(function() {
$('#modal1').modal();
});
You can check out my solution in this fiddle: https://jsfiddle.net/AndreasMolle/7f6hmgcf/13/
Another solution might be to do it this way:
<a class="waves-effect waves-light btn view" href="#modal1">View Scores</a>

MaterializeCCS documents aren't too clear, here's how I solved my problem.
HTML
<!-- Modal Trigger -->
<a class="waves-effect waves-light btn modal-trigger" href="#modal1">Modal</a>
<!-- Modal Structure -->
<div id="modal1" class="modal">
<div class="modal-content">
<h4>Modal Header</h4>
<p>A bunch of text</p>
</div>
<div class="modal-footer">
Agree
</div>
</div>
JavaScript
$(document).ready(function(){
// the "href" attribute of .modal-trigger must specify the modal ID that wants to be triggered
$('.modal-trigger').leanModal();
});

I recently updated my project to materializecss 0.98.0 and with this version I need to initialize modals before open it.
//Old
$('#modal1').openModal();
//New
$('#modal1').modal().modal('open');
I don't find any configuration like "autoOpen" on the modal initial options :(.

$( document ).ready(function() {
$('.modal').modal();
$('#modal1').on('click', function() {
});
});
https://jsfiddle.net/juands/z512cb7f/3/ check this link

Try Materialize.Modal class
let modal=new Materialize.Modal($("#yourModal"));
modal.open(); //Open it on some event
modal.close(); //This is not needed as you can close it with the modal buttons. It's tricky

Why these confirmation modal is not showing up?

I use a template that uses bootstrap. I'm having trouble with showing a modal.
The form has a jquery validation, if everything is ok then when clicking on submit a confirmation modal should appear to ask user if he is sure he wants to store that information. If form doesn't pass validation then a simple message appears.
For the mentioned actions I build this:
<form action="#" id="form_sample_2" class="form-horizontal">
<div class="alert alert-error hide">
<button class="close" data-dismiss="alert"></button>Existen errores en el formulario. Por favor verifique.</div>
<!-- modal -->
<div id="myModal" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel3" aria-hidden="true">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true"></button>
<h3 id="myModalLabel3">Cargar Usuario</h3>
</div>
<div class="modal-body">
<p></p>
</div>
<div class="modal-footer">
<button class="btn" data-dismiss="modal" aria-hidden="true">Cerrar</button>
<button data-dismiss="modal" class="btn green" id="btnYes">Confirmar</button>
</div>
</div>
<!-- end modal -->
</form>
As you can see, modal and error message has the attribute "hide"...
the js file:
var handleValidation2 = function () {
// for more info visit the official plugin documentation:
// http://docs.jquery.com/Plugins/Validation
var form2 = $('#form_sample_2');
var error2 = $('.alert-error', form2);
var success2 = $('#myModal', form2);
//IMPORTANT: update CKEDITOR textarea with actual content before submit
form2.on('submit', function () {
for (var instanceName in CKEDITOR.instances) {
CKEDITOR.instances[instanceName].updateElement();
}
})
form2.validate({
errorElement: 'span', //default input error message container
errorClass: 'help-inline', // default input error message class
focusInvalid: false, // do not focus the last invalid input
ignore: "",
rules: {
//some code
},
submitHandler: function (form) {
success2.show();
error2.hide();
}
//some code
On this snippet, if form doesn't pass validation then error2.hide() function shows up the alert error message.
Problem comes when form passes validation when success2.show() function should show confirmation modal, but it's not doing that. Nothing appears when form is ok and I'm wondering what am I doing wrong.
Any help would be really much appreciated.
J.

Instead of success2.show(); use success2.modal('show')
This should fix your issue

submitHandler: function (form) {
success2.removeAttr('aria-hidden');
success2.show();
error2.hide();
}
do u try to remove att aria-hidded. hope that work for u

ASP.NET MVC validation not working on bootstrap modal

I can't get the bootstrap modal and asp.net mvc validation start working together. I've got a complex form with some validation displayed in bootstrap modal. Unfortunetely when I hit the submit button the validation doesn't work at all.
The form uses standard asp.net mvc validation. Below there is a part of it just to get the idea of how it is build:
#using (Html.BuildForm().AddClass("form-horizontal").Id("contact-add-popup").EncType(FormEncType.MultipartData).Begin()) {
#Html.AntiForgeryToken()
#Html.Partial("_Alerts")
<div class="control-group">
<div class="control-group company-field">
#Html.BuildLabelFor(m => m.Name).AddClass("control-label")
<div class="controls">
#Html.BuildTextBoxFor(m => m.Name).AddClass("input-xxlarge")
#Html.ValidationMessageFor(m => m.Name)
</div>
</div>
(...)
Here is my modal:
<div id="createContactModal" class="modal hide fade modal-contact" tabindex="-1" role="dialog" aria-labelledby="createContactModalLabel" aria-hidden="true" data-backdrop="static">
<div class="modal-header">
<h4 class="modal-label" id="createContactModalLabel">Add contact</h4>
</div>
<div class="modal-body">
#Html.Partial("_CreateContact", new ContactCreateModel())
</div>
<div class="modal-footer">
Zapisz
<button class="btn" data-dismiss="modal" aria-hidden="true">Zamknij</button>
</div>
And some javascript that I hope to get the validation working:
$('#createContactModal').on('shown', function () {
$("#contact-add-popup").removeData("validator");
$("#contact-add-popup").removeData("unobtrusiveValidation");
$.validator.unobtrusive.parse("#contact-add-popup");
});
$('#contact-add-popup').on('submit', function(e){
e.preventDefault();
$.validator.unobtrusive.parse($("#contact-add-popup"));
if ($('#contact-add-popup').valid()){
alert('AJAX');
}
});
The line if ($('#contact-add-popup').valid()) returns always true. How can I get the modal and validation to work?

You should try this way:
var form = $("#contact-add-popup")
.removeData("validator")
.removeData("unobtrusiveValidation");
$.validator.unobtrusive.parse(form);
Stackoverflow: unobtrusive validation not working with dynamic content

After some research I found that javascript validation script files were missing - so the client side validation was not working at all. After including these files everything works fine.
Thanks for all answers.

Add this in the base view, load modal and enable client side validation.
#section scripts {
#{ await Html.RenderPartialAsync("_ValidationScriptsPartial"); }
#* The normal bootstrap behavior is to only grab the content
for the modal once, if you need to pull in different partial
views then the data on the modal will have to be cleared. *#
<script src="~/lib/jquery-validation-unobtrusive/jquery.validate.unobtrusive.js"></script>
<script type="text/javascript">
$(function () {
$('#modal-container').on('show.bs.modal', function (event) {
var button = $(event.relatedTarget); // Button that triggered the modal
var url = button.attr("href");
var modal = $(this);
//enable client side validation after page is loaded
modal.find('.modal-content').load(url, function () {
$('#registration_form').removeData("validator");
$('#registration_form').removeData("unobtrusiveValidation");
$.validator.unobtrusive.parse('#registration_form');
});
});
});
</script>
}

$.post keeps redirecting me

I have problem with jquery $.post function. I use this function a lot and same function works fine except in one case and I don't understand why it keeps redirecting me after script was executed, here is js code:
var record;
$('.delbtt').on('click', function(e){
e.preventDefault();
var deleteid = $(this).parent().parent().find('#id').text();
record = $(this).parent().parent();
$('#delrecord').empty().val(deleteid);
});
$(document).on('submit', '#delteform', function() {
var formData = $(this).serialize();
$.post('includes/delete.php',formData,processData);
function processData(data){
record.remove();
};
});
HTML:
<!-- Modal -->
<div class="modal fade" id="deleteFormModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<form id="deleteform" class="form-horizontal" role="form" action="includes/delete.php" method="POST"> <!-- -->
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h4 class="modal-title">Delete record</h4>
</div>
<div class="modal-body">
<p>Are you sure you want to delete this person?</p>
</div>
<input type="hidden" id="delrecord" name="delrecord" value="" />
<div class="modal-footer">
<button type="button" class="btn btn-default empty" data-dismiss="modal">Cancel</button>
<button id="delentry" type="submit" class="btn btn-danger">Delete Person</button>
</div>
</form>
</div><!-- /.modal-content -->
</div><!-- /.modal-dialog -->
</div><!-- /.modal -->
I know that function is executed successfully, because if I put alert("Why is this not working?"); after record.remove();, I can see alert and in background code executed, but instead of staying at the same page it redirects me to 'includes/delete.php'. I tried disabling all other $.post functions that I have in my JS, I tried using $('#deleteform').submit(), I tried putting it outside of my main $(document).ready(function() {}); same results... Always same result it redirects me after function completes instead of staying on a page. Does anybody have idea why am I getting this behavior?
php code:
<?php
include('budgetprop/Initialize.php');
Database::GetInstance()->ConnectToServer($errors);
$record = $_POST['delrecord'];
# CONNECT TO DB
if(Database::GetInstance()->ConnectToServer($errors)){
$insertSQL1 = "DELETE FROM salaries WHERE record_id = '".$record."' ";
$stmt1 = sqlsrv_query(Database::GetInstance()->databaseConnection, $insertSQL1);
# IF THERE IS AN ERROR
if(!$stmt1){
echo "Error, cannot delete record";
}else{
Database::GetInstance()->LastInsertId($stmt1);
}
# IF ALL QUERIES WERE SUCCSESSFUL, COMMIT THE TRANSACTION, OTHERWISE ROLLBACK
if($stmt1 && !$errors){
sqlsrv_commit(Database::GetInstance()->databaseConnection);
# FREE THE STATEMENT
Database::GetInstance()->FreeDBStatement($stmt1);
echo "success";
return true;
}else{
sqlsrv_rollback(Database::GetInstance()->databaseConnection);
# FREE THE STATEMENT
Database::GetInstance()->FreeDBStatement($stmt1);
return false;
}
# NO CONNECTION WAS MADE
}else{
return false;
};
?>
preventDefault() doesn't work either

It sounds like your form is still being submitted, hence the redirect. You can stop it with preventDefault()...
$(document).on('submit', '#deleteform', function(e) {
e.preventDefault();
var formData = $(this).serialize();
$.post('includes/delete.php',formData,processData);
function processData(data){
record.remove();
};
});

Assuming "deleteform" is the ID of a form element on your page, within which you have an input or button of type "submit", I would suggest changing the delentry button to have a type of "button".
Most browsers will perform a POST/GET on a form that has an input or button of type submit when that button is clicked.
I would then update your jQuery event handler to select the button and specify an onclick event:
$('#delentry').click(function() {
...
});
If you wish to maintain some form of graceful degradation, you could leave the markup as a submit type button and on $(document).ready(), update the type of the button to be "button".
