通过UserAgent判断智能手机(设备,Android,IOS)、微信浏览器

定义和用法

userAgent 属性是一个只读的字符串，声明了浏览器用于 HTTP 请求的用户代理头的值。

一般来讲，它是在 navigator.appCodeName 的值之后加上斜线和 navigator.appVersion 的值构成的。

例如：Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; SV1; .NET CLR 1.1.4322)。

语法

navigator.userAgent

判断手机设备

c#代码：

String ua = Context.Request.UserAgent.ToString();
//string[] keywords = { "Android", "iPhone", "iPod", "iPad", "Windows Phone", "MQQBrowser" };
            //排除 Windows 桌面系统           
            if (ua.ToLower().IndexOf("android") > -1 || ua.ToLower().IndexOf("adr") > -1)
            {
                //Android
            }
            else
            {
                //ios
            }

js代码：

var ua = navigator.userAgent.toLowerCase().toString();
    console.log(ua);
    //string[] keywords = { "Android", "iPhone", "iPod", "iPad", "Windows Phone", "MQQBrowser" };
    //排除 Windows 桌面系统           
    if (ua.indexOf("android") > -1 || ua.indexOf("adr") > -1)
    {
        //amdroid
        siteid = 196;
    }
    else if (ua.indexOf("iphone") > -1 || ua.indexOf("ipod") > -1 || ua.indexOf("iPad") > -1)
    {
        //ios
    }

判断是否微信平台

js代码：

//判断是否为微信浏览器
function isWeiXinBrowser() {
    var ua = navigator.userAgent.toLowerCase();
    if (ua.match(/MicroMessenger/i) == 'micromessenger') {
        return true;
    } else {
        return false;
    }
}
