Bootstrap data-toggle modal content within a function

I'm new to programming, and I have this simple question but I can't figure out how to do it.
I got this working code from Boostrap 4:
<!-- Button trigger modal -->
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModalLong">
Launch demo modal
</button>
<!-- Modal -->
<div class="modal fade" id="exampleModalLong" tabindex="-1" role="dialog" aria-labelledby="exampleModalLongTitle" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLongTitle">Modal title</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
...
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
But instead of having a button I want to create a function to fire up the modal content:
function openModal(){
/* DESCRIPTION: Open the warning modal */
// data-toggle="modal" data-target="#exampleModal"
}
But I don't know how to the same thing as data-toggle and
data-target do in the button click.
Someone has a hint how to do that?

You have to use the Bootstrap JS api for the modal ( Link attached at the end of this answer ).
Here is the straight answer :-)
function openModal(){
/* DESCRIPTION: Open the warning modal */
$('#exampleModalLong').modal('show');
}
Here is another SO question related to this : How can I trigger a Bootstrap modal programmatically?
Here is a detailed link on Bootstrap official documentation on various javascript methods for modals.
https://getbootstrap.com/docs/4.0/components/modal/#methods

Just use this line in your function:
$('#myModal').modal('show');
Note: remember to replace your modal id with myModal.

Bootstrap popup model not working on my webpage

The bootstrap popup is not showing up on my website. I have copied the popup code from the official Bootstrap website.
Here is the link to my website Link to webiste
The popup button is located before the footer credits.

Current condition :
Query Bootstrap Modal is not working
Below code is copy pasted from your give url http://home.india-market.online/
It is working properly in separate example
Solution:
You have footer, <footer class="footer-social-icon text-center section_padding_70 clearfix">
Some how there is z-index:-101; and position:fixed; in <footer>
You need to remove model outside from <footer> and apply directly before </body> tag ends.
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css"/>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
<!-- Button trigger modal -->
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModalLong">
Launch demo modal
</button>
<!-- Modal -->
<div class="modal fade" id="exampleModalLong" tabindex="-1" role="dialog" aria-labelledby="exampleModalLongTitle" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLongTitle">Modal title</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
...
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
I hope it will start working normally.
Old Code from website is :

The reason is that modal content is placed (nested) inside footer element. Move that modal div to body and modal will appear.

Using Bootstrap 3, is there a way to reuse the same HTML for different media queries to practice DRY?

I've been reading Bootstrap 3's documents about modals, and it makes sense to use this HTML for the modal content. I'd be creating this modal on mobile:
<!-- Button trigger modal -->
<button type="button" class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
Launch demo modal
</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">Modal title</h4>
</div>
<div class="modal-body">
...
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
My question is, I'd want to reuse the HTML inside the body of the modal for a sidebar on the desktop media query. How would I do so without repeating the HTML for a second time as a completely different div that simply contains the exact same content?

Dismiss bootstrap modal changes on cancel

I have a bootstrap modal, which has table with attribute contenteditable = trueinside of it (table is created dynamically with js). I'd like to set up a neat feature - if user presses cancel then the changes in table will be dismissed. I understand that i could do this with writing a function for different states and then calling out the previous state in case of cancel. I'm just thinking that is there a quicker-better-faster approach?
I did some searching and found one link which had similar issue, but the approach and result there are a bit different from mine which means that it didn't work for me.
Here's my code - parts of it are in Estonian, i don't think in general code is necessary for this question but i'll still provide:
<div class="modal fade" id="ajamasinModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<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"><i class="fa fa-cog" style="font-size:20px"></i> Ajamasin</h4>
</div>
<div class="modal-body">
<div id="changeablevoor"></div>
<button type="button" class="btn btn-primary" onClick="muudaClick()">Change</button>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-danger" data-dismiss="modal">Cancel</button>
<button type="button" class="btn btn-success" data-dismiss="modal">Save</button>
</div>
</div>
</div>
</div>

Try the following approach ( view comments inline ):
Html
<div class="modal fade" id="ajamasinModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
//...
<div class="modal-footer">
<button type="button" class="btn btn-danger" data-dismiss="modal">Cancel</button>
<button type="button" class="btn btn-success" data-dismiss="modal">Save</button>
</div>
</div>
</div>
</div>
JS
// Add hidden event of the modal
$('#ajamasinModal').on('hidden.bs.modal', function (e) {
cancelModal(); // Call the function to cancel the modal after hiding of the modal
})
// Cancel the modal
function cancelModal() {
// Re-generate content with default values
}
More information about these events of Bootstrap Modal can be found here in the Docs of Bootstrap: Bootstrap Modal Events

Bootstrap Confirmation Dialog

I currently have a page that asks the user if they want to actually do something. Currently, it works like this:
Do This Thing
<script type="text/javascript">
function promptUser() {
return confirm("Are you sure you want to do this thing?");
}
</script>
Now, the user wants to add some graphics, etc to the dialog. For that reason, I want to use the Bootstrap Modal window as I have it elsewhere in my code. I've added the following:
<div id="confirmDialog" class="modal hide fade">
<div class="modal-body">
Are you sure you want to do this thing?
</div>
<div class="modal-footer">
<button type="button" data-dismiss="modal" class="btn btn-primary" id="confirmed">Yes</button>
<button type="button" data-dismiss="modal" class="btn">No</button>
</div>
</div>
However, I'm not sure how to wire up the interaction with the link. If the user says "No", I want to stay on the page. If the user says "Yes", I want to redirect the user to the url in the href. How do I set this up?
Thanks

HTML
<!-- Button trigger modal -->
<button type="button" class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
click me
</button>
<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<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">Modal title</h4>
</div>
<div class="modal-body">
...
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary" id="confirm">confirm</button>
</div>
</div>
</div>
</div>
JS
$('#confirm').on('click', funciton(){
window.location.href = "http://stackoverflow.com";
});

$('#confirmed').click(function(){
location.href = "some URL "
});
It will stay on no as it's default behavior or bootstrap modal and we have attached event on yes button on mention above.

Late to the party, but things have moved on in the last few years. For reference, in case anyone else needs to ask the same question, it might be easier to wrap the modal in a form, and use an input to respond:
<!-- Modal -->
<form action="letsdothisthing.php method="post">
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<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">Modal title</h4>
</div>
<div class="modal-body">
...
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<input type="submit" class="btn btn-primary value="YES" ></input>
</div>
</div>
</div>
</div>
</form>
