移动端设备判断，简短够用

var isWebkit = /Webkit/i.test(navigator.userAgent),    isChrome = /Chrome/i.test(navigator.userAgent),    isMobile = !!("ontouchstart" in window),    isAndroid = /Android/i.test(navigator.userAgent),    isIE = document.documentMode;

移动端设备判断仍然简短判断的也挺全

js判断手机移动设备是Android平台还是ios平台

if (/android/i.test(navigator.userAgent)){    // todo : android} if (/ipad|iphone|mac/i.test(navigator.userAgent)){    // todo : ios}
