html添加js代码

var system = {};
var p = navigator.platform;
var u = navigator.userAgent;
 
system.win = p.indexOf("Win") == 0;
system.mac = p.indexOf("Mac") == 0;
system.x11 = (p == "X11") || (p.indexOf("Linux") == 0);
if (system.win || system.mac || system.xll) {//如果是PC转 
    if (u.indexOf('Windows Phone') > -1) {  //win手机端
 
    }
    else {
        window.location.href = "Expires.aspx?error=1";
    }
}
