make bootstrap twitter dialog modal draggable

问题:

I'm trying to make bootstrap twitter dialog modal draggable with this jquery plugin:

http://threedubmedia.com/code/event/drag#demos

but it doesn't work.

var $div = $('html');
console.debug($('.drag'));
$('#modalTest')
    .drag("start", function(ev, dd) {
        dd.limit = $div.offset();
        dd.limit.bottom = dd.limit.top + $div.outerHeight() - $(this).outerHeight();
        dd.limit.right = dd.limit.left + $div.outerWidth() - $(this).outerWidth();
    })
    .drag(function(ev, dd) {
        $(this).css({
            top: Math.min(dd.limit.bottom, Math.max(dd.limit.top, dd.offsetY))
            , left: Math.min(dd.limit.right, Math.max(dd.limit.left, dd.offsetX))
        });
    }); 

Have you idea how can I do it?

回答1:

$("#myModal").draggable({
    handle: ".modal-header"
}); 

it works for me. I got it from there. if you give me thanks please give 70% to Andres Ilich

回答2:

The top-ranked solution (by Mizbah Ahsan) is not quite right ...but is close. If you apply draggable() to the modal dialog element, the browser window scroll bars will drag around the screen as you drag the modal dialog. The way to fix that is to apply draggable() to the modal-dialog class instead:

$(".modal-dialog").draggable({
    handle: ".modal-header"
});

Thanks!

You can use the code below if you dont want to use jQuery UI or any third party pluggin. It's only plain jQuery.

$(".modal").modal("show");

$(".modal-header").on("mousedown", function(mousedownEvt) {
    var $draggable = $(this);
    var x = mousedownEvt.pageX - $draggable.offset().left,
        y = mousedownEvt.pageY - $draggable.offset().top;
    $("body").on("mousemove.draggable", function(mousemoveEvt) {
        $draggable.closest(".modal-dialog").offset({
            "left": mousemoveEvt.pageX - x,
            "top": mousemoveEvt.pageY - y
        });
    });
    $("body").one("mouseup", function() {
        $("body").off("mousemove.draggable");
    });
    $draggable.closest(".modal").one("bs.modal.hide", function() {
        $("body").off("mousemove.draggable");
    });
});

.modal-header {
    cursor: move;
}

<div class="modal fade" tabindex="-1" role="dialog">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
        <h4 class="modal-title">Modal title</h4>
      </div>
      <div class="modal-body">
        <p>One fine body&hellip;</p>
      </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><!-- /.modal-content -->
  </div><!-- /.modal-dialog -->
</div>

Like others said, the simpliest solution is just call draggable() function from jQuery UI just after showing modal:

$('#my-modal').modal('show')
              .draggable({ handle: ".modal-header" });

But there is a several problems with compatibility between Bootstrap and jQuery UI so we need some addition fixes in css:

.modal
{
    overflow: hidden;
}
.modal-dialog{
    margin-right: 0;
    margin-left: 0;
}
.modal-header{      /* not necessary but imo important for user */
    cursor: move;
}

回答5:

use the jquery UI draggable, much simpler http://jqueryui.com/draggable/

回答6:

i did this:

$("#myModal").modal({}).draggable();

and it make my very standard/basic modal draggable.

not sure how/why it worked, but it did.

回答7:

In my case I am enabling draggable. It works.

var bootstrapDialog = new BootstrapDialog({
    title: 'Message',
    draggable: true,
    closable: false,
    size: BootstrapDialog.SIZE_WIDE,
    message: 'Hello World',
    buttons: [{
         label: 'close',
         action: function (dialogRef) {
             dialogRef.close();
         }
     }],
});
bootstrapDialog.open();

Might be it helps you.

回答8:

In my own case, i had to set backdrop and set the top and left properties before i could apply draggable function on the modal dialog. Maybe it might help someone ;)

if (!($('.modal.in').length)) {       
$('.modal-dialog').css({
     top: 0,
     left: 0
   });
}
$('#myModal').modal({
  backdrop: false,
   show: true
});

$('.modal-dialog').draggable({
  handle: ".modal-header"
});
