Js to get browser information and page information

1. js gets browser information, including determining whether the browser is mobile or not, browser information, and android version

2. js obtains the url, domain, and title of the page.

 

Function browserInfo () {var browser = {versions: function () {var u = window. navigator. userAgent; // android var num; if (u. indexOf ('think')>-1) {// IEreturn IE;} else if (u. indexOf ('presto ')>-1) {// operareturn Opera;} else if (u. indexOf ('gecko ')>-1 & u. indexOf ('html ') =-1) {// firefoxreturn Firefox;} else if (u. indexOf ('applewebkit '& u. indexOf ('safari ')>-1)>-1) {// Apple, Google kernel if (u. indexO F ('chrome ')>-1) {// chromereturn Chrome;} else if (u. indexOf ('opr') {// webkit Operareturn Opera_webkit} else {// Safarireturn Safari;} else if (u. indexOf ('mobile')>-1) {// if (!! U. match (/(I [^;] +; (U ;)? CPU. + Mac OS X/) {// iosif (u. indexOf ('iphone ')>-1) {// iphonereturn iPhone} else if (u. indexOf ('ipod ')>-1) {// ipodreturn iPod} else if (u. indexOf ('ipad ')>-1) {// ipadreturn iPad} else if (u. indexOf ('android')>-1 | u. indexOf ('linux ')>-1) {// androidnum = u. substr (u. indexOf ('android') + 8, 3); return {type: Android, version: num };} else if (u. indexOf ('bb10')>-1) {// return BB10;} else if (u. indexOf ('iemobile ') {// windows phonereturn Windows Phone }}}// browser version var browserVsersion = browser. versions (); // the current page path var url = window. location. href; // the current page domain name var host = window. location. host; // the current page domain name var host2 = document. domain; alert (host2); // the current page title var title = document. title; // source URL urlvar referer; if (document. referrer. length> 0) {referer = document. referrer;} try {if (referer. length = 0 & opener. location. href. length> 0) {referer = opener. location. href ;}} catch (e) {referer = window. location. href;} // current page source urlreferer = referer. replace ('HTTP ://','');}
