thymeleaf fragments - html modal for confirmation dialog - javascript

I have a confirmation dialog that is resurfacing on some pages so I thought that I can make a thymeleaf fragment for it.
I created a new html page (modal.html) and a div containing the modal:
<div th:fragment="confirm">
<div id="confirm" class="modal fade" 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">Please confirm</h4>
</div>
<div class="modal-body">
<button type="button" class="btn btn-danger" data-dismiss="modal">Cancel</button>
<a id="btn-confirm" class="btn btn-primary pull-right">Confirm</a>
</div>
</div>
</div>
</div>
</div>
Then I included it like this on the pages:
<div th:include="fragments/modal :: confirm"></div>
This kind of syntax worked for my header.
The problem is that it is visible at all times now.
When I include the same modal code on the page directly it only pops up when toggled.
Can someone help me?
Thanks!

The modal CSS class has display: none;, so it's hidden by default.
Your div that includes the fragment probably is inside an element that has a CSS class that sets the CSS display property to something different than none, and overwrites the modal CSS class.
Check in the developers extension (F12) the style of the element to see what overwrites the display property
And make sure you include
<link rel="stylesheet" th:href="#{/css/bootstrap.min.css}"/>

Load Bootstrap Modal content only when it has been opened

I'm using Bootstrap Modal to load lightboxes with some resource-heavy content.
But the content is loaded immediately with the page. And since there's several lightboxes it slows the page down significantly.
I want the content to load only when the modal button is clicked. But I don't want to call the modal code from a separate page, since that would complicate everything.
Is there some way to use JS or AJAX to load the modal content only when the modal box opens?
Somehow trigger it to load when the button is clicked and then turn the content off, when the box is closed.
Also bear in mind that I don't know almost anything about JS or AJAX.
--EDIT: It would be great if the same solution could be applied to tabbed content--
The code I'm using:
<!-- Trigger the modal with a button -->
<button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">Open</button>
<!-- Modal -->
<div class="modal fade" id="myModal" role="dialog">
<div class="modal-dialog modal-lg">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
</div>
<div class="modal-body">
<iframe width='100%' height='368' src='#' frameborder='0' allowfullscreen></iframe>
</div>
</div>
</div>
</div>

strange symbols in modal instead of content

we created a website where we want to show some examples of our cards as thumbnails, but when you click on it a larger picture should be displayed in a modal window. Now locally (windows machine) it works perfect, but once hosted (linux machine) the whole content (title, markup, picture, buttons) of the modal are displayed as a set of strange symbols.
The code of the modal:
<div class="col-md-4">
<a href="images/JUNO-FOTO-MW.png" class="thumbnail" data-toggle="modal" data-target="#ModalJUNO">
<img src="images/JUNO-FOTO.gif" alt="geboortekaartje Juno" style="width:200px;height:200px">
<p>geboortekaartje </br>Juno</p>
</a>
</div>
<!-- Modal -->
<div id="ModalJUNO" class="modal fade" role="dialog">
<div class="modal-dialog modal-lg">
<!-- Modal content-->
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">Geboortekaartje Juno</h4>
</div>
<div class="modal-body">
<img src="images/JUNO-FOTO-MW.gif" title="geboortekaartje Juno" alt="geboortekaartje Juno wil nu eventjes niet laden" width="850" height="850">
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
The result of the hosted site
A part of the result:
Since it is not only the picture but the whole modal that is displayed like this, it does not seems like it is an encoding problem.
Any help is greatlty appreciated!
Remove href from your <a> tags.
I debugged bootstrap.js and found, that jQuery.load function is used to load modal's content.
Take a look at

Opening Bootstrap Modal with anchor tag

I am trying to open a Bootstrap Modal using the anchor tag. This is my HTML:
<ul class="dropdown-menu">
<li><a data-toggle="modal" href="#createModal">create group chat</a>
<!-- Modal -->
<div class="modal fade" id="createModal" 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>
</li>
When I click on the anchor tag for create group chat, the background blacks out but the actual dialog box does not appear. My website has another Bootstrap Modal that load when the page first loads, so I am not sure if this problem is being caused by a naming conflict. This Modal is named createModal and the other one I am using is called myModal
Try moving the modal outside of the li element.
Also, to get the fiddle working, you just need to add the external references to bootstrap.

Bootstrap Modal not working completely on CodePen

I am attempting to make a Calculator in JavaScript. I'm almost at the end, so I added a modal through Bootstrap, which contains an instruction list(somewhat like a manual). While the modal works perfectly on my local machine, it works only halfway through in CodePen.
The issue appears to be that a click on the button brings up the modal but it does not go away if you click on the "Close" button or even the "cross" icon on the modal. It looks like the modal is disabled when it opens up, and the only way to get everything working again is to refresh the codepen link.
As I'm making this calculator for an online tutorial exercise, I need to submit it via CodePen only. So I've got to make this work.
Here's the relevant HTML -
<div id="instructions">
<!-- Button trigger modal -->
<button type="button" class="btn btn-primary btn-large" data-toggle="modal" data-target="#myModal">
Launch Instructions
</button>
<!-- Modal -->
<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">Instructions</h4>
</div>
<div class="modal-body">
<ul class="list-group">
<li class="list-group-item">Click on the AC button before beginning each new calculation.</li>
<li class="list-group-item">For square root of a number, first press the number then press the square root button.</li>
<li class="list-group-item">An operation that results in a number too large to fit on the screen will display zero instead.</li>
<li class="list-group-item">If a number has too many digits after the decimal point to fit on screen, some of the digits will be truncated.</li>
<li class="list-group-item">Some operations like divide by zero, and square root of negative integers are not permitted.</li>
</ul>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
</div>
In CodePen, I've added BootStrap through CSS quickadd, and for JS, I added jQuery and then Bootstrap(in that order), so I'm not sure why it doesn't work. I have followed the same order in my local files, where the modal works perfectly-
<script src="http://code.jquery.com/jquery-1.11.3.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js" integrity="sha384-0mSbJDEHialfmuBBQP6A4Qrprq5OVfW37PRR3j5ELqxss1yVqOtnepnHVP9aJ7xS" crossorigin="anonymous"></script>
<script type="text/javascript" src="4.js"></script>
Here's the CodePen link for my calculator. Interestingly though, I made another Pen here where I was testing just the modal bit, and it works just fine here.
It is happening because you have made position of instructions fixed.
As you had made #instructions fixed, which is the parent of modal, the modal was relatively above its parent(#instructions), but the parent(#instructions) itself was below the backdrop(<div class="modal-backdrop fade in"></div>) as it's(#instructions) z-index was not set which gets created when you open a modal window.
If I remove position fixed from the div instructions your modal works fine.
Instead of fixing the div to the bottom you can directly apply the CSS on the button.
#instructions button {
position: fixed;
left: 44%;
bottom: 0;
}
Or else you could just move the #instructions above the backdrop div.
#instructions{
z-index: 1049;/*keeping z-index above 1040*/
position: fixed;
left: 44%;
bottom: 0;
}
A small demo of the same issue, where one cannot click on close buttons inside the modal in Chrome whereas the buttons are clickable in FF. Here the modal is placed inside another container whose position is fixed.
Try getting the z-index of modal's parent in FF and Chrome.
In this demo $('.parent').css('z-index');
Chrome z-index is set to 0
FF z-index is set to 'auto'
This explains the above issue.
$(function(){
$('.modal-body > span').html($('.parent').css('z-index'));
});
.parent{
position: fixed;
}

I had this problem too.
Problem is comming from html, created by bootstrap js:
<div class="modal-backdrop fade in"></div>
This line is created directly before end of element. This cause "z-index stacked element problem." I believe that bootstrap .js do creation of this element wrong. If you have in mvc layout page, this script will cause still the same problem. Beter js idea cut be to get target modal id and inject this line to html before...
this.$backdrop = $(document.createElement('div'))
.addClass('modal-backdrop ' + animate)
.appendTo(this.$body)
SO SOLUTION IS repair bootstrap.js - part of modal:
.appendTo(this.$body)
//REPLACE TO THIS:
.insertBefore(this.$element)
SOLUTION 2:
add to your page this script:
$('.modal').appendTo("body")
Solution3:
Add to css:
.modal-backdrop{display:none;}

Add page to certain div in bootstrap modal windows

I am working on a project that use bootstrap, in it I need to show modal windows that contain other html page I use the following code
<a class="menuItemManageContent"
href="<%= request.getContextPath()%>/news/index/NEWS/0943ac5b-e556-49eb-acef-a112a56e3e7b/managePortlet.html"
data-toggle="modal" data-target="#modal-table_<%= request.getParameter("instanceId").toString() %>">Manage content</a>
<div id="modal-table_<%= request.getParameter("instanceId").toString() %>" class="modal fade" tabindex="-1">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header no-padding">
<div class="table-header">
<button type="button" class="close" data-dismiss="modal"
aria-hidden="true">
<span class="white">×</span>
</button>
mange
</div>
</div>
<div id="contentBody" class="modal-body no-padding">
</div>
</div>
<!-- /.modal-content -->
</div>
</div>
the code above work fine , it is showing the modal with my page in it the only part I need to put my content in contentBody so I still have the header for the modal as I design it, my question here is there is an easy way to do that with no javascript, can I tell the data-target to put the page in the contentBody div instead of the default modal content which is override my div.
fine, i got it work I just move the header out of the content and that solve the issue, I will leave this question hopefully it help someone else
