How to open a Bootstrap modal window using jQuery?

Question

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();
});

Check out the complete solution here:

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>

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 use javascript.

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

Answer 3

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.

Answer 4

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>

Answer 5

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');
