第一种方法：angularjs自定义指令：

指令：

   app.directive(‘onBlankHide‘,function () {
        return {
            restrict: ‘A‘,scope: {
                pop: ‘=‘
            },link: function (scope,element,attr) {
                element.on(‘click‘,function (e) {
                    $(‘#‘ + scope.pop).fadeIn();
                    $(document).click(function () {
                        $(‘#‘ + scope.pop).hide();
                    });
                     //阻止底层冒泡
                     e.stopPropagation();
                });

                $(‘#‘ + scope.pop).click(function (e) {
                    //阻止底层冒泡
                    e.stopPropagation();
                })
            }
        }
    });

调用方法：

<input id="btn" type="button" value="显示DIV" on-blank-hide pop="‘myDiv‘" />
    <div id="myDiv">
        This is a div;
    </div>

说明：pop是向指令传递的值，表示关联弹框的id名，不要忘‘’

完整栗子（代码可直接copy）：

常规方法(代码可直接copy)：

        #myDiv {
            background-color: #FFFFFF;
            width: 250px;
            height: 250px;
            display: none;
        }
    </style>
</head>

<body>
    <input id="btn" type="button" value="显示DIV" />
    <div id="myDiv">
        This is a div;
    </div>
</body>
<script type="text/javascript">
    $(function () {
        $("#btn").click(function (event) {
            $(‘#myDiv‘).fadeIn();
            $(document).one("click",function () { //对document绑定一个影藏Div方法
                    $(‘#myDiv‘).hide();
                });

            event.stopPropagation(); //阻止事件向上冒泡
        });
        $(‘#myDiv‘).click(function (event) {

            event.stopPropagation(); //阻止事件向上冒泡
        });
    });
  
</script>

</html>

深夜还在码代码，但是我总觉得是值得的，因为我又懂了一个知识点。
