判断手机客户端

var browser = {
versions: function () {
var u = navigator.userAgent;
return {
ios: !!u.match(/\(i[^;]+;( U;)? CPU.+Mac OS X/), //ios终端
android: u.indexOf('Android') > -1 || u.indexOf('Linux') > -1 //android终端或uc浏览器
};
}()
}
if (browser.versions.ios == true) {
window.location.href = "https://itunes.apple.com/us/app/guang-xi-ren-cai-wang-guan/id882436427?mt=8";
} else if (browser.versions.android == true) {
window.location.href = "http://app.gxrc.com/appdown?ID=1";
}
