2.JS判断手机操作系统（ios或android）并跳转到不同下载页面
$(function () {
???var u = navigator.userAgent, app = navigator.appVersion;
???var isAndroid = u.indexOf(‘Android‘) > -1 || u.indexOf(‘Linux‘) > -1; //g
???var isIOS = !!u.match(/\(i[^;]+;( U;)? CPU.+Mac OS X/); //ios终端
???if (isAndroid) {
???????window.location.href = ‘appDownload.html‘;
???}
???if (isIOS) {
???????window.location.href = ‘iosDownload.html‘;
???}
});
