Send parameter to Bootstrap modal window?

Question

I have a problem, I cannot pass any parameters to a modal window (using Bootstrap 3), I tried using the solution stated in this link, but I cannot make it work:

Dynamically load information to Twitter Bootstrap modal

(Solution kexxcream user).

But pressing the button, the display does not show me anything, apparently blocks, attached a picture below:

I have attached the code (same code post above left);

HTML Code:

      <div id="myModal" class="modal hide fade">
      <div class="modal-header">
        <button class="close" data-dismiss="modal">&times;</button>
        <h3>Title</h3>
      </div>
      <div class="modal-body">            
          <div id="modalContent" style="display:none;">

          </div>
      </div>
      <div class="modal-footer">
        <a href="#" class="btn btn-info" data-dismiss="modal" >Close</a>
      </div>
  </div>

JS Code:

    $("a[data-toggle=modal]").click(function() 
    {   
        var essay_id = $(this).attr('id');

        $.ajax({
            cache: false,
            type: 'POST',
            url: 'backend.php',
            data: 'EID='+essay_id,
            success: function(data) 
            {
                $('#myModal').show();
                $('#modalContent').show().html(data);
            }
        });
    });

Button:

<a href='#myModal' data-toggle='modal' id='2'> Edit </a>

PHP Code (backend.php):

<?php
$editId = $_POST['EID'];
?>
  <div class="jumbotron">
   <div class="container">
    <h1>The ID Selected is <?php echo $editId ?></h1>
   </div>
  </div>

$editId = filter_var($_POST["id"], FILTER_SANITIZE_NUMBER_INT); // just playing safe :) — Afonso Gomes, Mar 04 '16 at 00:43

There is a better solution than the accepted answer, specifically using data-* attributes. Setting the id to 1 will cause you issues if any other element on the page has id=1. Instead, you can do:

<button class="btn btn-primary" data-toggle="modal" data-target="#yourModalID" data-yourparameter="whateverYouWant">Load</button>

<script>
$('#yourModalID').on('show.bs.modal', function(e) {
  var yourparameter = e.relatedTarget.dataset.yourparameter;
  // Do some stuff w/ it.
});
</script>

i had to use `e.relatedTarget.dataset.yourparameter` (in lower case) even though I used `data-yourParameter` in the markup. Don't know why. – galdin May 21 '15 at 13:53
Huh, good to know. I guess I've never actually camelCased a data-* attribute before. Thx! – Joe May 22 '15 at 18:27

First of all you should fix modal HTML structure. Now it's not correct, you don't need class .hide:

<div id="edit-modal" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
                <h4 class="modal-title" id="myModalLabel">Modal title</h4>
            </div>
            <div class="modal-body edit-content">
                ...
            </div>
            <div class="modal-footer">
                <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
                <button type="button" class="btn btn-primary">Save changes</button>
            </div>
        </div>
    </div>
</div>

Then links should point to this modal via data-target attribute:

<a href="#myModal" data-toggle="modal" id="1" data-target="#edit-modal">Edit 1</a>

Finally Js part becomes very simple:

    $('#edit-modal').on('show.bs.modal', function(e) {

        var $modal = $(this),
            esseyId = e.relatedTarget.id;

        $.ajax({
            cache: false,
            type: 'POST',
            url: 'backend.php',
            data: 'EID=' + essayId,
            success: function(data) {
                $modal.find('.edit-content').html(data);
            }
        });
    })

I found the solution at: Passing data to a bootstrap modal

So simply use:

 $(e.relatedTarget).data('book-id');

with 'book-id' is a attribute of modal with pre-fix 'data-'

I have found this better way , no need to remove data , just call the source of the remote content each time

$(document).ready(function() {
    $('.class').click(function() {
        var id = this.id;
        //alert(id);checking that have correct id
        $("#iframe").attr("src","url?id=" + id);
        $('#Modal').modal({ 
            show: true 
        });
    });
});
