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(); }); 

Answer 1

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:

Answer 2

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');
