使用js判断web网站访问端是电脑还是手机

<script type="text/javascript">

var browser = {

/*

* 获得当前浏览器的版本信息

*/

versions: function () {

var u = window.navigator.userAgent, app = window.navigator.appVersion;

return {

//IE内核

trident: u.indexOf('Trident') > -1,

//opera内核

presto: u.indexOf('Presto') > -1,

//苹果、谷歌WebKits内核

webKit: u.indexOf('AppleWebKit') > -1,

//火狐内核

gecko: u.indexOf('Gecko') > -1 && u.indexOf('KHTML') == -1,

//是否为移动终端

mobile: !!u.match(/AppleWebKit.*Mobile.*/),

//ios终端

ios: !!u.match(/\(i[^;]+;( U;)? CPU.+Mac OS X/),

//android终端

android: u.indexOf('Android') > -1,

//iPhone

iPhone: u.indexOf('iPhone') > -1,

//iPod

iPod: u.indexOf('iPod') > -1,

//iPad

iPad: u.indexOf('iPad') > -1,

//是否web应该程序，没有头部与底部

webApp: u.indexOf('Safari') == -1

};

}()

}
