使用device.js检测设备并实现不同设备展示不同网页
html代码：
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<script src="device.js"></script>
</head> <body style="margin: auto; position: absolute; width:100%; height: 100%">
<script>
var isMobile = device.mobile(),
isIos = device.ios(),
isAndroid = device.android();
if(isMobile){
alert("手机");
}else{
alert("pc");
}
if(isIos){
alert("ios");
}
if(isAndroid){
alert('安卓');
} </script>
</body>
</html>
