JS 一些功能代码块[如判断设备]

function IsPC()  
       {  
           var userAgentInfo = navigator.userAgent;  
           var Agents = new Array("Android", "iPhone", "SymbianOS", "Windows Phone", "iPad", "iPod");  
           var flag = true;  
           for (var v = 0; v < Agents.length; v++) {  
               if (userAgentInfo.indexOf(Agents[v]) > 0) { flag = false; break; }  
           }  
           return flag;  
       }
