How do I get the coordinate position after using jQuery drag and drop?

How do I get the coordinate position after using jQuery drag and drop? I want to save the coordinate to a database, so that next time I visit, the item will be in that position. For example, x: 520px, y: 300px?

EDIT:

I am PHP and mysql programmer :)

Is there any tutorial out there?

This worked for me:

$("#element1").droppable(
{
    drop: function(event, ui)
    {
        var currentPos = ui.helper.position();
            alert("left="+parseInt(currentPos.left)+" top="+parseInt(currentPos.top));
    }
});

$(function() 
  {
    $( "#element" ).draggable({ snap: ".ui-widget-header",grid: [ 1, 1 ]});
  });
    $(document).ready(function() {
        $("#element").draggable({

None of the above worked for me.

Here's my solution- works great:

$dropTarget.droppable({
    drop: function( event, ui ) {

    // Get mouse position relative to drop target: 
    var dropPositionX = event.pageX - $(this).offset().left;
    var dropPositionY = event.pageY - $(this).offset().top;
    // Get mouse offset relative to dragged item:
    var dragItemOffsetX = event.offsetX;
    var dragItemOffsetY = event.offsetY;
    // Get position of dragged item relative to drop target:
    var dragItemPositionX = dropPositionX-dragItemOffsetX;
    var dragItemPositionY = dropPositionY-dragItemOffsetY;

    alert('DROPPED IT AT ' + dragItemPositionX + ', ' + dragItemPositionY);

(Based partly off solution given here: https://stackoverflow.com/a/10429969/165673)

I was need to save the start position and the end position. this work to me:

    $('.object').draggable({
        stop: function(ev, ui){
            var position = ui.position;
            var originalPosition = ui.originalPosition;
        }
    });

I would start with something like this. Then update that to use the position plugin and that should get you where you want to be.

Had the same problem. My solution is next:

$("#element").droppable({
    drop: function( event, ui ) {

        // position of the draggable minus position of the droppable
        // relative to the document
        var $newPosX = ui.offset.left - $(this).offset().left;
        var $newPosY = ui.offset.top - $(this).offset().top;

    }
});

Cudos accepted answer is great. However, the Draggable module also has a "drag" event that tells you the position while your dragging. So, in addition to the 'start' and 'stop' you could add the following event within your Draggable object:

    // Drag current position of dragged image.
    drag: function(event, ui) {

        // Show the current dragged position of image
        var currentPos = $(this).position();
        $("div#xpos").text("CURRENT: \nLeft: " + currentPos.left + "\nTop: " + currentPos.top);

    }

If you are listening to the dragstop or other events, the original position should be a ui parameter:

dragstop: function(event, ui) {
    var originalPosition = ui.originalPosition;
}

Otherwise, I believe the only way to get it is:

draggable.data("draggable").originalPosition

Where draggable is the object you are dragging. The second version is not guaranteed to work in future versions of jQuery.

I just made something like that (If I understand you correctly).

I use he function position() include in jQuery 1.3.2.

Just did a copy paste and a quick tweak... But should give you the idea.

// Make images draggable.
$(".item").draggable({

    // Find original position of dragged image.
    start: function(event, ui) {

        // Show start dragged position of image.
        var Startpos = $(this).position();
        $("div#start").text("START: \nLeft: "+ Startpos.left + "\nTop: " + Startpos.top);
    },

    // Find position where image is dropped.
    stop: function(event, ui) {

        // Show dropped position.
        var Stoppos = $(this).position();
        $("div#stop").text("STOP: \nLeft: "+ Stoppos.left + "\nTop: " + Stoppos.top);
    }
});

<div id="container">
    <img id="productid_1" src="images/pic1.jpg" class="item" alt="" title="" />
    <img id="productid_2" src="images/pic2.jpg" class="item" alt="" title="" />
    <img id="productid_3" src="images/pic3.jpg" class="item" alt="" title="" />
</div>

<div id="start">Waiting for dragging the image get started...</div>
<div id="stop">Waiting image getting dropped...</div>
