比较好的网站地址

1.在线查询身份证号地址：

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';
}
});
