JS根據瀏覽器的useAgent來判斷瀏覽器的類型

userAgent 屬性是一個只讀的字符串，聲明了瀏覽器用於 HTTP 請求的用戶代理頭的值。

javascript語法：navigator.userAgent

PHP語法：$_SERVER[‘HTTP_USER_AGENT‘]

ASP語法：Request.ServerVariables("HTTP_USER_AGENT")

ASP.NET語法：HttpContext.Current.Request.UserAgent

JSP語法：request.getHeader("User-Agent")

接下來，如何判斷瀏覽器的類型呢 ？

IE 瀏覽器 ：

JS 代碼:

//返回瀏覽器的類型: "ie", "firefox", "chrome", "opera", "safari", "unknow"

// author: aerchi

// site:www.aerchi.com

// blog: http://blog.csdn.net/aerchi/article/details/51697592

// email: [email protected]

// date: 2016-06-17

// update: 2016-08-11 00:56:00

// call like: getBrowser(1)
// return like "chrome/50.0.2661.102"
// call like: getBrowser()
// return like "chrome"
function getBrowser(getVersion)
{
//註意關鍵字大小寫
var ua_str = navigator.userAgent.toLowerCase(), ie_Tridents, trident, match_str, ie_aer_rv, browser_chi_Type;

console.log("article url: http://blog.csdn.net/aerchi/article/details/51697592");

//判斷IE 瀏覽器,
//blog: http://blog.csdn.net/aerchi/article/details/51697592
if("ActiveXObject" in self){
// ie_aer_rv: 指示IE 的版本.
// It can be affected by the current document mode of IE.
ie_aer_rv= (match_str = ua_str.match(/msie ([\d.]+)/)) ?match_str[1] :
(match_str = ua_str.match(/rv:([\d.]+)/)) ?match_str[1] : 0;

// ie: Indicate the really version of current IE browser.
ie_Tridents = {"trident/7.0": 11, "trident/6.0": 10, "trident/5.0": 9, "trident/4.0": 8};
//匹配 ie8, ie11, edge
trident = (match_str = ua_str.match(/(trident\/[\d.]+|edge\/[\d.]+)/)) ?match_str[1] : undefined;
browser_chi_Type = (ie_Tridents[trident] || ie_aer_rv) > 0 ? "ie" : undefined;
}else{
//判斷 windows edge 瀏覽器
// match_str[1]: 返回瀏覽器及版本號,如: "edge/13.10586"
// match_str[1]: 返回版本號,如: "edge"

//若要返回 "edge" 請把下行的 "ie" 換成 "edge"。 註意引號及冒號是英文狀態下輸入的
browser_chi_Type = (match_str = ua_str.match(/edge\/([\d.]+)/)) ? "ie" :
//判斷firefox 瀏覽器
(match_str = ua_str.match(/firefox\/([\d.]+)/)) ? "firefox" :
//判斷chrome 瀏覽器
(match_str = ua_str.match(/chrome\/([\d.]+)/)) ? "chrome" :
//判斷opera 瀏覽器
(match_str = ua_str.match(/opera.([\d.]+)/)) ? "opera" :
//判斷safari 瀏覽器
(match_str = ua_str.match(/version\/([\d.]+).*safari/)) ? "safari" : undefined;
}

console.log("author: aerchi, blog: http://blog.csdn.net/aerchi");

//返回瀏覽器類型和版本號

var verNum, verStr;

verNum = trident && ie_Tridents[trident] ? ie_Tridents[trident] : match_str[1];

verStr = (getVersion != undefined) ? browser_chi_Type+"/"+verNum : browser_chi_Type;
return verStr;
}
