    };

    //检测平台
    var p = navigator.platform;

    system.win = p.indexOf("Win") == 0;
    system.mac = p.indexOf("Mac") == 0;
    system.x11 = (p == "X11") || (p.indexOf("Linux") == 0);
    system.ipad = (navigator.userAgent.match(/iPad/i) != null)?true:false;

    if (system.win || system.mac || system.xll ||system.ipad) {
      
    } else {

       //some code;
