Answer 1

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);
            }
        });
    })

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>

Answer 3

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-'

Answer 4

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 
        });
    });
});
