判斷當(dāng)前訪問網(wǎng)站的設(shè)備是否是PC
<pre>
//平臺宣蠕、設(shè)備和操作系統(tǒng)
var system ={
win : false,
mac : false,
xll : false
};
//檢測平臺
var p = navigator.platform;
system.win = p.indexOf("Win") == 0;
system.mac = p.indexOf("Mac") == 0;
system.x11 = (p == "X11") || (p.indexOf("Linux") == 0);
//跳轉(zhuǎn)語句
if(system.win||system.mac||system.xll){
alert("PC訪問");
}else{
alert("非PC訪問");
}
</pre>
JS判斷訪問設(shè)備(userAgent)加載不同頁面民效。代碼如下：
<pre>
function browserRedirect() {
var sUserAgent = navigator.userAgent.toLowerCase();
var bIsIpad = sUserAgent.match(/ipad/i) == "ipad";
var bIsIphoneOs = sUserAgent.match(/iphone os/i) == "iphone os";
var bIsMidp = sUserAgent.match(/midp/i) == "midp";
var bIsUc7 = sUserAgent.match(/rv:1.2.3.4/i) == "rv:1.2.3.4";
var bIsUc = sUserAgent.match(/ucweb/i) == "ucweb";
var bIsAndroid = sUserAgent.match(/android/i) == "android";
var bIsCE = sUserAgent.match(/windows ce/i) == "windows ce";
var bIsWM = sUserAgent.match(/windows mobile/i) == "windows mobile";
if (! (bIsIpad || bIsIphoneOs || bIsMidp || bIsUc7 || bIsUc || bIsAndroid || bIsCE || bIsWM)) {
window.location.href = B頁面;
}
}
browserRedirect();
</pre>
JS判斷客戶端操作系統(tǒng)類型(platform)來定義不同的字體表現(xiàn)冕杠。
<pre>
// 更詳細(xì)的探測當(dāng)前客戶端使用的操作系統(tǒng)
function detectOS() {
var sUserAgent = navigator.userAgent;
var isWin = (navigator.platform == "Win32") || (navigator.platform == "Windows");
var isMac = (navigator.platform == "Mac68K") || (navigator.platform == "MacPPC") || (navigator.platform == "Macintosh") || (navigator.platform == "MacIntel"); if (isMac)
return "Mac";
var isUnix = (navigator.platform == "X11") && !isWin && !isMac;
if (isUnix) return "Unix";
var isLinux = (String(navigator.platform).indexOf("Linux") > -1);
if (isLinux) return "Linux";
if (isWin) {
var isWin2K = sUserAgent.indexOf("Windows NT 5.0") > -1 || sUserAgent.indexOf("Windows 2000") > -1;
if (isWin2K) return "Win2000";
var isWinXP = sUserAgent.indexOf("Windows NT 5.1") > -1 || sUserAgent.indexOf("Windows XP") > -1;
if (isWinXP) return "WinXP";
var isWin2003 = sUserAgent.indexOf("Windows NT 5.2") > -1 || sUserAgent.indexOf("Windows 2003") > -1;
if (isWin2003) return "Win2003";
var isWin2003 = sUserAgent.indexOf("Windows NT 6.0") > -1 || sUserAgent.indexOf("Windows Vista") > -1;
if (isWin2003) return "WinVista";
var isWin2003 = sUserAgent.indexOf("Windows NT 6.1") > -1 || sUserAgent.indexOf("Windows 7") > -1;
if (isWin2003) return "Win7";
}
return "other";
}
</pre>
另一種方法谨娜，使用mootools框架：
<pre>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<title>未命名</title>
<meta http-equiv="content-type" content="text/html;charset=utf-8" />
<meta name="generator" content="Geany 0.21" />
</head>
<body>
<h1>test Browser.Platform.linux</h1>
<script type="text/Javascript" language="JavaScript">
var s = null;
s = Browser.Platform.linux;
alert(s);
if (Browser.Platform.linux)
alert("linux");
else
alert("not linux");
</script>
</body>
</html>
</pre>
**使用JS架框有現(xiàn)成的判斷 **
例如motools架框中：
Browser.Platform.mac - (boolean) 當(dāng)前操作系統(tǒng)是否為Mac
Browser.Platform.win - (boolean) 當(dāng)前操作系統(tǒng)是否為Windows
Browser.Platform.linux - (boolean) 當(dāng)前操作系統(tǒng)是否為Linux
Browser.Platform.ipod - (boolean) 當(dāng)前操作系統(tǒng)是否為iPod Touch / iPhone
Browser.Platform.other - (boolean) 當(dāng)前操作系統(tǒng)即不是Mac, 也不是Windows或Linux
Browser.Platform.name - (string) 當(dāng)前操作系統(tǒng)的名稱
