Answer 1

Here is working snippet.

 function modal(ref) { alert($(ref).data("id")); } 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-id="1" onclick='modal(this)'>Open Modal</button> 

Answer 2

Read this: Why can't I use onClick to execute a function inside a jQuery $(document).ready function?

1. Add an id to the button: id="btnModal"

2. Delete this: onclick='modal(this)'

3. Put this (outside your document.ready ):

    $('#btnModal' ).click(function() { $('#myModal').modal('show'); });
