js 右键菜单(自己写的，有点问题求解)

右键页面空白处，出现div块 ，左键单击其他空白处，div消失问题：右键出现 div ,我单击div区域里面的东西，不会除外外面的左键事件，也就是div不消失，如何改，这个好像是什么冒泡了代码：

    <script type="text/javascript">
        $(document).ready(function () {
            var mouseX;
            var mouseY;
            $(document).bind("contextmenu", function (e) {  //去掉默认右键功能
                return false;
            });                       
            $(document).mousedown(function (e) {
                mouseX = event.clientX;
                mouseY = event.clientY;                
                if (3 == e.which) { //右键单击
                    $("#area").css('margin-left', mouseX);
                    $("#area").css('margin-top', mouseY);
                    $("#area").show();                                     
                } else if (1 == e.which) { //左键单击
                    $("#area").hide();                          
                }
            })        })          
    </script>
</head>
<body>
    <form id="form1" runat="server">
    <div>      
    <div id="area" style="width:150px; height:200px; background-color:red; display:none;" >
    <input type="button" value="我是按钮" onmousedown="alert('11');" />
    </div>
    </div>
    </form>
</body>
</html>
