如何删除div的可拖动事件？

我想在容器中添加新的.point,然后draggablge它,但首先我要取消绑定所有可拖动的$('.piont')事件,怎么做？

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript" src="http://code.jquery.com/ui/1.8.2/jquery-ui.js"></script>
<style type="text/css">
    *{margin:0;padding:0}
    .container{
        margin:50px;
        width:100px;
        height:100px;
        border:1px solid #777;
        position:relative
    }
    .point{
        width:20px;
        height:20px;
        background-color:tan;
        position:absolute;
    }
</style>
<script type="text/javascript">
    $(function(){
        $('.point').draggable({
            stop: function (e){
                alert(1);
            }
        }); 
    });

    function unbind_draggable(){
        // how can unbind draggable for .point?
    }
</script>
<div class="container">
    <div class="point"></div>
    <div class="point"></div>
    <div class="point"></div>
    <div class="point"></div>
</div>
<button onclick="unbind_draggable()">unbind_draggable</button>

要删除可拖动事件:

 $( ".selector" ).draggable( 'disable' ); OR
 $( ".selector" ).draggable( 'destroy' );

进一步的细节检查jQuery UI API文档.点击这里

对于你的问题:

function unbind_draggable(){
     $('point').draggable( 'destroy' );
     //OR
     $('point').draggable( 'disable' );
}
