## 实现 ##

webapp下新建droppable文件夹，在其下新建basic.html

<!DOCTYPE html>
    <html lang="en">
    <head>
        <meta charset="UTF-8">
        <title>可放置</title>
        <link rel="stylesheet" type="text/css" href="/easyui/themes/icon.css">
        <link rel="stylesheet" type="text/css" href="/easyui/themes/default/easyui.css">
        <script type="text/javascript" src="/easyui/jquery.min.js"></script>
        <script type="text/javascript" src="/easyui/jquery.easyui.min.js"></script>
    </head>
    <body>
    <style type="text/css">
        .drags{
            width:50px;
            hejght:50px;
            margin:5px;
            border:1px solid #ccc;
        }
        .container, #drop{
            width:300px;
            height:300px;
            border:1px solid #ccc;
            float:left;
            margin:5px;
        }
    </style>
    
    <div class="container">
        <div class="drags" id="drag1">drag1</div>
        <div class="drags" id="drag2">drag2</div>
        <div class="drags" id="drag3">drag3</div>
    </div>
    
    <div id="drop">
    </div>
    <script type="text/javascript">
            $(".drags").draggable({
                //拖拽时产生克隆对象
                proxy:"clone",
                //松开后返回原地
                revert:true
            });
            //设置为可放置
            $("#drop").droppable({
                //设置可接受的
                accept:"#drag1,#drag2",
                onDragEnter:function (e,source) {
                    //变成小手
                    $(source).draggable("options").cursor="pointer";
                    $(source).draggable("proxy").css("border","1px solid red");
                },
                onDragLeave:function (e,source) {
                    //变成不可放置
                    $(source).draggable("options").cursor="no-drop";
                    $(source).draggable("proxy").css("border","1px solid #ccc");
                },
                onDrop:function (e,source) {
    
                    $(this).append(source);
                }
            })
    </script>
    
    </body>
    </html>
