Passing data to a bootstrap modal

I think you can make this work using jQuery's .on event handler.

Here's a fiddle you can test; just make sure to expand the HTML frame in the fiddle as much as possible so you can view the modal.

HTML

<p>Link 1</p><a data-toggle="modal" data-id="ISBN564541" title="Add this item" class="open-AddBookDialog btn btn-primary" href="#addBookDialog">test</a><p> </p><p>Link 2</p><a data-toggle="modal" data-id="ISBN-001122" title="Add this item" class="open-AddBookDialog btn btn-primary" href="#addBookDialog">test</a><div class="modal hide" id="addBookDialog"> <div class="modal-header">    <button class="close" data-dismiss="modal">×</button>    <h3>Modal header</h3>  </div>    <div class="modal-body">        <p>some content</p>        <input type="text" name="bookId" id="bookId" value=""/>    </div></div>

JAVASCRIPT

$(document).on("click", ".open-AddBookDialog", function () {     var myBookId = $(this).data('id');     $(".modal-body #bookId").val( myBookId );     // As pointed out in comments,      // it is unnecessary to have to manually call the modal.     // $('#addBookDialog').modal('show');});

Here is a cleaner way to do it if you are using Bootstrap 3.2.0.

Link HTML

<a href="#my_modal" data-toggle="modal" data-book-id="my_id_value">Open Modal</a>

Modal JavaScript

//triggered when modal is about to be shown$('#my_modal').on('show.bs.modal', function(e) {    //get data-id attribute of the clicked element    var bookId = $(e.relatedTarget).data('book-id');    //populate the textbox    $(e.currentTarget).find('input[name="bookId"]').val(bookId);});

Here's how I implemented it working from @mg1075's code. I wanted a bit more generic code so as not to have to assign classes to the modal trigger links/buttons:

Tested in Twitter Bootstrap 3.0.3.

HTML

<a href="#" data-target="#my_modal" data-toggle="modal" data-id="my_id_value">Open Modal</a>

JAVASCRIPT

$(document).ready(function() {  $('a[data-toggle=modal], button[data-toggle=modal]').click(function () {    var data_id = '';    if (typeof $(this).data('id') !== 'undefined') {      data_id = $(this).data('id');    }    $('#my_element_id').val(data_id);  })});
