JavaScript–Apple设备检测示例代码

// Apple detection object
var Apple = {};
Apple.UA = navigator.userAgent;
Apple.Device = false;
Apple.Types = ["iPhone", "iPod", "iPad"];

for (var d = 0; d < Apple.Types.length; d++) {
  var t = Apple.Types[d];
  Apple[t] = !!Apple.UA.match(new RegExp(t, “i”));
  Apple.Device = Apple.Device || Apple[t];
}

// is this an Apple device?
alert(
  “Apple device? ” + Apple.Device +
  “\niPhone? ” + Apple.iPhone +
  “\niPod? ” + Apple.iPod +
  “\niPad? ” + Apple.iPad
);
