                                    if (obj && typeof obj.OperationType != "undefined") {
                                        obj.OperationType(1);
                                    }
                                };
                            }
                        };

在IE下，把上面的回调函数的“document.getElementById("btnDis")”改成“$("#btnDis")”这样绑定事件就不行，但是就算是原来的这里也没错，IE报其他地方的乱七八糟的错误。
