jquery draggable options

Question

i want the draggable object to revert back to its original position when i click a button. i used 'destroy' option but it doesnt seem to work. it disables the dragging but doesnt revert back to original position.

can someone help?

EDIT PART:

$('#Zoom').toggle(function() {
                $("#draggable").draggable({});},
            function() {
                $("#draggable").draggable('destroy');});

this is a toggle button that i am using to enable dragging. the destroy option only disables dragging and does not revert the object back to the original position.

also this is the button i want to make the object come back to its original position:

nextImg.addEventListener('click', function() {img.setAttribute("src", "img"+(++imgnum)+".jpg");}, false);

How about this?

<script type="text/javascript">
jQuery(document).ready(function() { 
    $("#draggable").data("Left", $("#draggable").position().left)
                    .data("Top", $("#draggable").position().top);
    $("#draggable").draggable();

    $("#nextImg").bind('click', function() {
        $("#draggable").animate(
            { "left": $("#draggable").data("Left"), 
                "top": $("#draggable").data("Top")
            }, "slow");
        $("#draggable").attr("src", "img"+(++imgnum)+".jpg");
    });
});
</script>

I've made some assumptions, such as the nextImg object having an id of "nextImg" so that I can bind the click event using jQuery (one less step in the javascript event binding process?) I'm also assuming that you don't really want to destroy the drag functionality.

Revert executes when dragging has stopped (with optional delay), not on click.

$(document).ready(function() {
   var originalTop = $('#draggable').position().top;
   var originalLeft = $('#draggable').position().left;

   $('#Zoom').toggle(
         function() {
            $("#draggable").draggable({});},
         function() {
            $("#draggable").draggable('destroy');
            $('#draggable').position().top = originalTop;
            $('#draggable').position().left= originalLeft;
         });
});
