var agent = navigator.userAgent.toLowerCase();

var arr=[];

var Browser="";

var verinNum="";

//IE

if(agent.indexOf("msie") > 0){

var regStr_ie = /msie [/d.]+;/gi ;

Browser="IE";

Bversion=""+agent.match(regStr_ie)

}

//firefox

else if(agent.indexOf("firefox") > 0){

var regStr_ff = /firefox//[/d.]+/gi;

Browser="firefox";

Bversion=""+agent.match(regStr_ff);

}

//Chrome

else if(agent.indexOf("chrome") > 0){

var regStr_chrome = /chrome//[/d.]+/gi ;

Browser="chrome";

Bversion=""+agent.match(regStr_chrome);

}

//Safari

else if(agent.indexOf("safari") > 0 && agent.indexOf("chrome") < 0){

var regStr_saf = /version//[/d.]+/gi ;

Browser="safari";

Bversion=""+agent.match(regStr_saf);

}

//Opera

else if(agent.indexOf("opera")>=0){

var regStr_opera = /version//[/d.]+/gi ;

Browser="opera";

Bversion=""+agent.match(regStr_opera);

}else{

var browser=navigator.appName;

if(browser=="Netscape"){

var version=agent.split(";");

var trim_Version=version[7].replace(/[ ]/g,"");

var rvStr=trim_Version.match(/[/d/.]/g).toString();

var rv=rvStr.replace(/[,]/g,"");

Bversion=rv;

Browser="IE"

}

}

verinNum=(Bversion+"").replace(/[^0-9.]/ig,"");

arr.push(Browser);

arr.push(verinNum);

return arr;

}
