$(function(){var _IE = (function () {            var v = 3, div = document.createElement('div'), all = div.getElementsByTagName('i');            while (                div.innerHTML = '<!--[if gt IE ' + (++v) + ']><i></i><![endif]-->',                all[0]            );            return v > 4 ? v : false;        } ());                if(_IE>8||!_IE){        $.getScript("<%=basePath%>/js/common_h.js");         $.getScript("<%=basePath%>/jslib/sweet-alert/js/sweet-alert.js");         $('head').append('<link href="<%=basePath%>/jslib/sweet-alert/css/sweet-alert.css" rel="stylesheet" type="text/css" />')        }else{         $.getScript('<%=basePath%>/js/common.js');        }})
