var dialogoffset = {     top: 10,     left: 200 }; $('button').click(function () {     var parent = $('#desktop');     var parentpos = parent.offset();     var parentindex = $('#desktop').index(parent);     var numdialogs = $('.dlg' + parentindex).length;     var dialogtop = parentpos.top + dialogoffset.top + numdialogs * 30;     var dialogposition = [parentpos.left + dialogoffset.left + numdialogs * 30, dialogtop];      $('<div class="dlg' + parentindex + '"></div>').dialog({         position: dialogposition,         width: 250,         close: function () {             $(this).dialog('destroy').remove();         }     }); });
