使用js代码获取浏览器版本信息如下：
例如：ie9.0 firefox34.0 chrome37.0等等
/**
* Get browser name agent version
* return browser name version
* */
function getBrowserNameAndVersion(){
var agent = navigator.userAgent.toLowerCase();
var regStr_ie = /msie [\d.]+/gi ;
var regStr_ff = /firefox\/[\d.]+/gi
var regStr_chrome = /chrome\/[\d.]+/gi ;
var regStr_saf = /safari\/[\d.]+/gi ;
var browserNV = "";
//IE
if(agent.indexOf("msie") > 0)
{
browserNV = agent.match(regStr_ie) ;
}
//firefox
if(agent.indexOf("firefox") > 0)
{
browserNV = agent.match(regStr_ff) ;
}
//Chrome
if(agent.indexOf("chrome") > 0)
{
browserNV = agent.match(regStr_chrome) ;
}
//Safari
if(agent.indexOf("safari") > 0 && agent.indexOf("chrome") < 0)
{
browserNV = agent.match(regStr_saf) ;
}
browserNV = browserNV.toString();
//other
if(""==browserNV){
browserNV = "Is not a standard browser";
}
//Here does not display "/"
if(browserNV.indexOf('firefox')!= -1 || browserNV.indexOf('chrome')!= -1){
browserNV = browserNV.replace("/","");
}
//Here does not display space
if(browserNV.indexOf('msie')!= -1){
//msie replace IE & trim space
browserNV = browserNV.replace("msie","ie").replace(/\s/g,"");
}
//return eg:ie9.0 firefox34.0 chrome37.0
return browserNV;
}
获取浏览器其他信息(可以从中截取字符串，判断其他信息)：
var browver = getBrowserNameAndVersion();
var bname = bsnav("name");
var bagent = bsnav("agent");
var bversion = bsnav("version");
alert("loading……" + browver);
alert("version: "+bversion);
alert("agernt: "+bagent);
alert("name: "+bname);
/**
* Get browser name agent version
* parm getString
* return getInfo
* */
function bsnav(string){
switch (string) {
case "version":
var browser_version = navigator.appVersion;
return browser_version;
// break;
case "agent":
var browser_agent = navigator.userAgent;
return browser_agent;
// break;
case "name":
var browser_name = navigator.appName;
return browser_name;
// break;
default:
var browser_no = "Input parameter error";
return browser_no;
// break;
}
}
