Jquery Draggable with Zoom Problem

jQuery - draggable div with zoom

You don't need to set zoom property. I just added the difference to draggable's position which occurs due to the zoom property. Hope it helps.

Fiddle

JS

var zoom = $('#canvas').css('zoom');
var canvasHeight = $('#canvas').height();
var canvasWidth = $('#canvas').width();

$('#dragme').draggable({
    drag: function(evt,ui)
    {
        // zoom fix
        ui.position.top = Math.round(ui.position.top / zoom);
        ui.position.left = Math.round(ui.position.left / zoom);

        // don't let draggable get outside the canvas
        if (ui.position.left < 0) 
            ui.position.left = 0;
        if (ui.position.left + $(this).width() > canvasWidth)
            ui.position.left = canvasWidth - $(this).width();  
        if (ui.position.top < 0)
            ui.position.top = 0;
        if (ui.position.top + $(this).height() > canvasHeight)
            ui.position.top = canvasHeight - $(this).height();  

    }                 
});

Jquery droppable area wrong if zoomed

Thats a known jQueryUI-Bug since many years (See this or this).
AFAIK there is still no way to fix this.

Maybe these changes in the jQueryUI-Code itself may help you.
