精准判断是360、IE和其他浏览器

function myexplorer(){
    var explorer = window.navigator.userAgent;
    if (!!window.ActiveXObject || "ActiveXObject" in window){//IE
        if (!window.XMLHttpRequest){
            return myexplorer="IE"; //IE6
        }else if (window.XMLHttpRequest && !document.documentMode){
            return myexplorer="IE"; //IE7
        }else if (!-[1,] && document.documentMode && !("msDoNotTrack" in window.navigator)){
            return myexplorer="IE"; //IE8
        }else{//IE9 10 11
            var hasStrictMode=(function(){
                "use strict";
                return this===undefined;
            }());
            if (hasStrictMode){
                if (!!window.attachEvent){
                    return myexplorer="IE"; //IE10
                }else{
                    return myexplorer="IE"; //IE11
                }
            }else{
                return myexplorer="IE"; //IE9
            }
        }
    }else{//非IE
        //application/vnd.chromium.remoting-viewer 可能为360特有
        var is360 = _mime("type", "application/vnd.chromium.remoting-viewer");

        if (isChrome() && is360) {
            return myexplorer= "360";
        }else{
            return myexplorer= "other"; //其他浏览器
        }
    }
}

var browser = myexplorer();
if(browser == "IE" || browser == "360"){
    get_video_list();
}else{
   alert("其他");
}

//检测是否是谷歌内核(可排除360及谷歌以外的浏览器)
function isChrome(){
    var ua = navigator.userAgent.toLowerCase();

    return ua.indexOf("chrome") > 1;
}
//测试mime
function _mime(option, value) {
    var mimeTypes = navigator.mimeTypes;
    if(mimeTypes){
        for (var mt in mimeTypes) {
            if (mimeTypes[mt][option] == value) {
                return true;
            }
        }
        return false;
    }
}

方法二

$.browser = function () {
    var userAgent = navigator.userAgent;
    var isOpera = userAgent.indexOf("Opera") > -1;
    if (isOpera) {
       return "Opera"
    };
    if (userAgent.indexOf("Firefox") > -1) {
      return "Firefox";
    }
   if (userAgent.indexOf("Chrome") > -1) {
       if (window.navigator.webkitPersistentStorage.toString().indexOf('DeprecatedStorageQuota') > -1) {
           return "Chrome";
        } else {
             return "360";
       }
    }
    if (userAgent.indexOf("Safari") > -1) {
      return "Safari";
    }
      if (userAgent.indexOf("compatible") > -1 && userAgent.indexOf("MSIE") > -1 && !isOpera) {
          return "IE";
     };
}
