jquery – 如何将网格从一个栅栏拖动到另一个栅格？

$(function () { //DOM Ready

    $(".gridster ul").gridster({
        widget_margins: [5,5],widget_base_dimensions: [160,160]
    });

    var gridster = $(".gridster ul").gridster().data('gridster');
    $( ".draggable" ).draggable();
    $( ".gridster " ).droppable({
        drop: function( event,ui ) {
            $( ".draggable" ).removeAttr("style");
            gridster.add_widget('<li class="new"></li>',1,1);                 
        }
    });                         
});
