function myBrowser(){ version:function(){ var u=navigator.userAgent; return { opera:u.indexOf("Opera")>-1,//opera浏览器 ie:u.indexOf("compatible")>-1&&u.indexOf("MSIE")>-1&&!isOpera,//IE浏览器 firfox:u.indexOf("Firefox")>-1,//火狐浏览器 safari:u.indexOf("Safari")>-1,//safari浏览器 chrome:u.indexOf("Chrome")>-1,//谷歌浏览器 ios:!!u.match(/\(i[^;]+;( U;)?

}
var browser=myBrowser.version;
if(browser=="ie"){}
var userAgent = navigator.userAgent; //取得浏览器的userAgent字符串 if (isIE) { var IE5 = IE55 = IE6 = IE7 = IE8 = IE9 =IE10 =IE11 =false; var reIE = new RegExp("MSIE (\\d+\\.\\d+);"); reIE.test(userAgent); var fIEVersion = parseFloat(RegExp["$1"]); IE55 = fIEVersion == 5.5; IE6 = fIEVersion == 6.0; IE7 = fIEVersion == 7.0; IE8 = fIEVersion == 8.0; IE9 = fIEVersion == 9.0; IE10 = fIEVersion == 10.0; IE11= fIEVersion == 11.0; if (IE55) {return "IE55";} if (IE6) {return "IE6";} if (IE7) {return "IE7";} if (IE8) {return "IE8";} if (IE9) {return "IE9";} if (IE10) {return "IE10";} if (IE11) {return "IE11";} }//isIE end
