通过UserAgent判断智能手机(设备,Android,IOS)

最近一直在升级公司的手机站点，出了个触屏版专用的，做好后，就尝试通过 Agent 来判断相应的智能手机设备，然后跳转到新的手机站点

经过不懈的努力，终于搜集了比较全的智能设备的 Agent，然后又写了程序，直接上代码吧，希望能帮助到你

///<summary>    /// 根据 Agent 判断是否是智能手机    ///</summary>    ///<returns></returns>    public static bool CheckAgent()    {        bool flag = false;        string agent = HttpContext.Current.Request.UserAgent;        string[] keywords = { "Android", "iPhone", "iPod", "iPad", "Windows Phone", "MQQBrowser" };           //排除 Windows 桌面系统            if (!agent.Contains("Windows NT") || (agent.Contains("Windows NT") && agent.Contains("compatible; MSIE 9.0;")))            {                //排除 苹果桌面系统                if (!agent.Contains("Windows NT") && !agent.Contains("Macintosh"))                {                    foreach (string item in keywords)                    {                        if (agent.Contains(item))                        {                            flag = true;                            break;                        }                    }                }            }          return flag;    }

代码解释：

1. !agent.Contains("Windows NT") && !agent.Contains("Macintosh") 排除Window 桌面系统和苹果桌面系统

2. "Android", "iPhone", "iPod", "iPad", "Windows Phone", "MQQBrowser" 这些是判断智能设备Agent中的关键词

3. MQQBrowser 为 QQ 手机浏览器，QQ 手机的Agent 比较特殊，所以单独判断

下面搜集的一些Agent，话说找到这么多的智能设备，好不容易啊：

改写为JS

/**

*/
$.checkMobile = function(){
    var flag = false;
   var agent = navigator.userAgent.toLowerCase();
   var keywords = [ "android", "iphone", "ipod", "ipad", "windows phone", "mqqbrowser" ];

    //排除 Windows 桌面系统
    if (!(agent.indexOf("windows nt") > -1) || (agent.indexOf("windows nt") > -1 && agent.indexOf("compatible; msie 9.0;") > -1)) {

        if (!(agent.indexOf("windows nt") > -1) && !agent.indexOf("macintosh") > -1 ) {
            for (var item in keywords) {
                if (agent.indexOf(item) > -1 ) {
                    flag = true;
                    break;
                }
            }
        }
    }
   return flag;
