How to obtain browser Information

Window has a navigator object to let us know all the information about the browser. We can use a series of API functions to know the information about the browser.

The JavaScript code is as follows:
Copy codeThe Code is as follows: function message () {txt = "<p> browser code name:" + navigator. appCodeName + "</p>"; txt + = "<p> browser name:" + navigator. appName + "</p>"; txt + = "<p> browser platform and version:" + navigator. appVersion + "</p>"; txt + = "<p> whether to enable cookie:" + navigator. cookieEnabled + "</p>"; txt + = "<p> operating system platform:" + navigator. platform + "</p>"; txt + = "<p> User-agent header value:" + navigator. userAgent + "</p>"; document. getElementById ("example "). innerHTML = txt ; If (navigator. appName = "Netscape" | navigator. appName = "Microsoft Internet Explorer") & (parseFloat (navigator. appVersion)> = 4) {alert ("your browser is advanced! ");} Else {alert (" it's time to upgrade your browser! ");}}

We can use this function to notify the user browser whether to update the browser, and also to help the user know the browser information.
