javascript – Jquery draggable / droppable和sortable组合

我被要求创建一个正方形网格,其中每个正方形可能包含或不包含链接,这些链接应该能够围绕网格移动.

我认为draggable / droppable将是可行的方式并且它可以正常工作,但是,现在我们希望能够让draggables交换,如果一个被丢弃在另一个之上.所以它现在看起来像是可以排序的.但是,sortable看起来更像是列表的意思,而我没有像列表那样编写它.

有没有一种简单的方法来制作我到目前为止所做的工作,或者我是否需要使用可排序的方式完全重写它？我是javascript的新手,我花了一段时间才能做到这一点,而且我不是要求代码,但我担心必须重新计算整个事情！任何意见？

这是我的代码的一个小提琴：http://jsfiddle.net/kvVkT/

和代码：

HTML

<div id="gridcontainer">
    <div id="-2:-2" class="droppable occupied">
        <a href="" id ="508" class="bookmark draggable white" title="white" "target="_blank">1</a>
    </div>
    <div id="-2:-1" class="droppable">2</div>
    <div style="clear:both"></div>
    <div id="-2:0" class="droppable">3</div>
    <div id="-2:1" class="droppable occupied">
        <a href="" id ="567" class="bookmark draggable white" title="white" "target="_blank">4</a>
    </div>
    <div style="clear:both"></div>
</div>

CSS

#gridcontainer{position:relative;padding:25px;color:#ff0004;BACkground:#ffffff;}
.droppable{width:65px; height:65px;float:left; margin:5px;BACkground:#000000;}
.bookmark {float:left;width:65px; height:65px;display:block;position:absolute;}
.position{float:left;width:65px; height:65px;display:block;}
.position:hover{BACkground-image:url(../img/tilehover.png);}
.bookmark.ui-draggable-dragging {-moz-Box-shadow: 0 0 5px #d9d9d9; -webkit-Box-shadow: 0 0 5px #d9d9d9; Box-shadow: 0 0 5px #d9d9d9;}
.draggable{ BACkground:#888888;}
[draggable] {
  -moz-user-SELEct: none;
  -khtml-user-SELEct: none;
  -webkit-user-SELEct: none;
  user-SELEct: none;
}

JavaScript的

$('.draggable').draggable({ start: function() {$('#dropdownAddTile').slideDown();},stop: function() {$('#dropdownAddTile').slideUp();},containment: '#container',snap:'.droppable',snapMode:'inner',revert:'invalid',snapTolerance: 32});
$('.droppable').droppable({drop: handleDropEvent,accept: function(E){if(e.hasClass('draggable')) { if (!$(this).hasClass('occupied')) {return true; }}}});
function handleDropEvent( event,ui ) {
      event.preventDefault();
      var draggable = ui.draggable;
      var droppable = $(this);
      var droppablEID = $(this).attr("id");
      var draggablEID = ui.draggable.attr("id");
      $('.draggable').draggable({Containment: '#container',snapTolerance: 32});
      $('.droppable').droppable({drop: handleDropEvent,accept: function(E){if(e.hasClass('draggable')) { if (!$(this).hasClass('occupied')) {return true; }}}});
      var initPosit = ui.draggable.parent().attr('id');
      //save new position
      $.post("tiles/updatetilePosition",{ draggablEID:draggablEID,droppablEID: droppablEID }).done(function(data) {
         //alert(data);
      })
      $(this).addClass('occupied');
      ui.draggable.parent().removeClass('occupied');
      if($(ui.draggablE).parent() !==$(this)){
            $(ui.draggablE).appendTo($( this ));
      }
}

感激地收到任何意见

$(function () {
    $('#container div').draggable({
        containment: "#container",Helper: 'clone',snap: true,snapMode: 'inner',snapTolerance: 32,revert: 'invalid'
    });

    $('#container div').droppable({
        hoverClass: 'ui-state-highlight',drop: function (event,ui) {
            var _drop = $(this),_drag = $(ui.draggablE),_dropChildren = _drop.children(),//original drop children
                _dragChilden = _drag.children(); //original drag children

            if(_dropChildren.length > 0){
                _dropChildren.appendTo(_drag);
            }

            _dragChilden.appendTo(_drop);
        }
    });
});
