JS 判断运行当前脚本的应用程序是否为手机端或者一些其他信息，在我的工作中遇到的不是十分频繁，被我的同事一问就给问住了，所以把之前找到的一些知识点整理出来，供大家参考，若哪里不对欢迎指出，我会及时的更改 (#^.^#)。
window.navigator
先从这个属性入手：window.navigator 返回一个navigator对象的引用，可以用它来查询一些关于运行当前脚本的应用程序的相关信息。
常用属性和方法：（想知道详细属性和方法的请点MDN）
Navigator 对象属性
| 属性 | 说明 |
|---|---|
| appCodeName | 返回当前浏览器的内部“代码”名称,该名称可能是不"正确"的. |
| appName | 返回当前浏览器的正式名称,该名称可能是不"正确"的. |
| appVersion | 返回当前浏览器的版本号,该值可能是不"正确"的. |
| cookieEnabled | 返回一个布尔值,表明当前浏览器是否启用了cookies. |
| platform | 返回一个字符串,表明当前所使用的系统平台类型. |
| userAgent | 返回当前浏览器的user agent字符串. |
Navigator 对象方法
| 方法 | 描述 |
|---|---|
| javaEnabled() | 表明当前浏览器是否启用了对Java的支持. |
| vibrate() | 如果设备支持震动(手机或其他),则触发设备震动. |
| registerContentHandler | 允许网站将自己注册成为一个给定MIME类型的内容的处理程序. |
eg:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
</head>
<body>
<div id="test"></div>
<script>
txt = "<p>浏览器代号: " + navigator.appCodeName + "</p>";
txt+= "<p>浏览器名称: " + navigator.appName + "</p>";
txt+= "<p>浏览器版本: " + navigator.appVersion + "</p>";
txt+= "<p>启用Cookies: " + navigator.cookieEnabled + "</p>";
txt+= "<p>硬件平台: " + navigator.platform + "</p>";
txt+= "<p>用户代理: " + navigator.userAgent + "</p>";
txt+= "<p>用户代理语言: " + navigator.systemLanguage + "</p>";
document.getElementById("test").innerHTML=txt;
</script>
</body>
</html>
常用跳转代码
<script type="text/javascript">

测试是什么终端
var u = navigator.userAgent;
var isAndroid = u.indexOf('Android') > -1 || u.indexOf('Adr') > -1; //android终端
var isiOS = !!u.match(/(i[^;]+;( U;)? CPU.+Mac OS X/); //ios终端
alert('是否是Android：'+isAndroid);
alert('是否是iOS：'+isiOS);
