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>
引入device.js
