How to open a Bootstrap modal window using jQuery?

JavascriptJqueryTwitter Bootstrap

Javascript Problem Overview

I'm using Twitter Bootstrap modal window functionality. When someone clicks submit on my form, I want to show the modal window upon clicking the "submit button" in the form.

<form id="myform" class="form-wizard">
    <h2 class="form-wizard-heading">BootStap Wizard Form</h2>
    <input type="text" value=""/>
    <input type="submit"/>
</form>

<!-- Modal -->
<div id="myModal" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
    <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
        <h3 id="myModalLabel">Modal header</h3>
    </div>
    <div class="modal-body">
        <p>One fine body…</p>
    </div>
    <div class="modal-footer">
        <button class="btn" data-dismiss="modal" aria-hidden="true">Close</button>
        <button class="btn btn-primary">Save changes</button>
    </div>
</div>

jQuery:

$('#myform').on('submit', function(ev) {
    $('#my-modal').modal({
        show: 'false'
    });	
	
		
	var	data = $(this).serializeObject();
    json_data = JSON.stringify(data);
    $("#results").text(json_data); 
	$(".modal-body").text(json_data); 
	 
    // $("#results").text(data);
 
	ev.preventDefault();
});

Javascript Solutions

Solution 1 - Javascript

Bootstrap has a few functions that can be called manually on modals:

$('#myModal').modal('toggle');
$('#myModal').modal('show');
$('#myModal').modal('hide');

You can see more here: Bootstrap modal component

Specifically the methods section.

So you would need to change:

$('#my-modal').modal({
    show: 'false'
});

to:

$('#myModal').modal('show');

If you're looking to make a custom popup of your own, here's a suggested video from another community member:

Solution 2 - Javascript

Most often, when $('#myModal').modal('show'); doesn't work, it's caused by having included jQuery twice. Including jQuery 2 times makes modals not to work.

Remove one of the links to make it work again.

Furthermore, some plugins cause errors too, in this case add

jQuery.noConflict(); 
$('#myModal').modal('show');

Solution 3 - Javascript

In addition you can use via data attribute

<button type="button" data-toggle="modal" data-target="#myModal">Launch modal</button>

In this particular case you don't need to write javascript.

You can see more here: http://getbootstrap.com/2.3.2/javascript.html#modals

Solution 4 - Javascript

Just call the modal method(without passing any parameters) using jQuery selector.

Here is example:

$('#modal').modal();

Solution 5 - Javascript

If you use links's onclick function to call a modal by jQuery, the "href" can't be null.

For example:

... ...
<a href="" onclick="openModal()">Open a Modal by jQuery</a>
... ...
... ...
<script type="text/javascript">

function openModal(){

    $('#myModal').modal();
}		
</script>

The Modal can't show. The right code is :

<a href="#" onclick="openModal()">Open a Modal by jQuery</a>

Solution 6 - Javascript

Here is how to load bootstrap alert as soon as the document is ready. It is very easy just add

 $(document).ready(function(){
   $("#myModal").modal();
});

I made a demo on W3Schools.

<!DOCTYPE html>
<html lang="en">
<head>
  <title>Bootstrap Example</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <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/3.2.1/jquery.min.js"></script>
  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
</head>
<body>

<div class="container">
  <h2>Here is how to load a bootstrap modal as soon as the document is ready </h2>
  <!-- Trigger the modal with a button -->


  <!-- Modal -->
  <div class="modal fade" id="myModal" role="dialog">
    <div class="modal-dialog">
    
      <!-- Modal content-->
      <div class="modal-content">
        <div class="modal-header">
          <button type="button" class="close" data-dismiss="modal">&times;</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>
  
</div>

<script>
$(document).ready(function(){
   $("#myModal").modal();
});
</script>

</body>
</html>

Check out the complete solution here:

http://www.w3schools.com/bootstrap/tryit.asp?filename=trybs_ref_js_modal_show&stacked=h

Make sure to put libraries in required order to get result:

1- First bootstrap.min.css 2- jquery.min.js 3- bootstrap.min.js

(In other words jquery.min.js must be call before bootstrap.min.js)

    <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/3.1.1/jquery.min.js">
</script> 

 <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>

Solution 8 - Javascript

Try to use jQuery instead of $ sign when calling the function, it worked in my case as you can see below.

jQuery.noConflict(); 
jQuery('#myModal').modal('show');

jQuery.noConflict(); because when jQuery('#myModal').modal('show'); doesn't work, it's caused by having included jQuery twice. Including jQuery 2 times makes modals not to work. and it would resolve the problem in that case, as in my case it is repeating.

Solution 9 - Javascript

I tried several methods which failed, but the below worked for me like a charm:

$('#myModal').appendTo("body").modal('show');

Solution 10 - Javascript

Try

$("#myModal").modal("toggle")

To open or close the modal with id myModal.

If the above is not working then it means bootstrap.js has been overridden by some other js file. Here is a solution

1:- Move bootstrap.js to the bottom so that it will override other js files.

2:- Make sure the order is like below

<script src="plugins/jQuery/jquery-2.2.3.min.js"></script>
<!-- Other js files -->
<script src="plugins/jQuery/bootstrap.min.js"></script>

Solution 11 - Javascript

<script type="text/javascript">
    $(function () {
        $("mybtn").click(function () {
            $("#my-modal").modal("show");
        });
    });
</script>

Solution 12 - Javascript

<form id="myform" class="form-wizard">
    <h2 class="form-wizard-heading">BootStap Wizard Form</h2>
    <input type="text" value=""/>
    <input type="submit" id="submitButton"/>
</form>

<!-- Modal -->
<div id="myModal" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
    <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
        <h3 id="myModalLabel">Modal header</h3>
    </div>
    <div class="modal-body">
        <p>One fine body…</p>
    </div>
    <div class="modal-footer">
        <button class="btn" data-dismiss="modal" aria-hidden="true">Close</button>
        <button class="btn btn-primary">Save changes</button>
    </div>
</div>

You can launch the modal with the code below this.

$(document).ready(function(){
    $("#submitButton").click(function(){
        $("#myModal").modal();
    });
});
