How to detect which type and version of browser does the User is using ?

I tried the following code, but it is not working.

var browserType = navigator.appName;
Alert(browserType);

Why are you doing this? Unless you're computing statistics this is probably the wrong thing to do. — sorpigal, Dec 10 '12 at 13:37
This isn't working because `Alert` is not defined ... use `alert` instead ... JavaScript is case-sensitive — Manse, Dec 10 '12 at 13:38
@ManseUK, Exactly you are correct. I tried with small letter. It is working fine. Thanks. — Earth, Dec 10 '12 at 13:40

Use small letter a instead of A in the alert.

var browserType = navigator.appName;
alert('the browser type is: ' + browserType);

Thanks. I found out the solution. – Earth Dec 10 '12 at 13:43
Your code gives the answer as `Netscape` when I tried in the `Chrome`. – Earth Dec 10 '12 at 13:54
@user1891768 It returns netscape for most browsers, Google 'window.navigator.appName netscape' - there are better ways to do what you're asking. – dsgriffin Dec 10 '12 at 13:57

If I code as `navigator.appName` alone, it works perfectly in all the browser. Also, I edited your answer since the above code is working fine as I checked in all the browsers. – Earth Dec 10 '12 at 14:00

Replace

Alert(browserType);

with

alert(browserType);

javascript is case sensitive.

But :

it's almost always wrong to try to detect the browser's type. Prefer detection of features
when we must, we usually explore (with regexes) navigator.appVersion or navigator.userAgent instead of navigator.appName.

For example :

 var isMobile = /Android|webOS|iPhone|iPad|iPod|BlackBerry|Mini/i.test(navigator.userAgent);

You can get the name of browser using this code:

window.navigator.appCodeName

Your code gives the answer as `Mozilla` for all browsers. – Earth Dec 10 '12 at 13:52
