Using javascript to detect browser type [duplicate]

Answer 1

I think jQuery got it right when they support testing for features instead of just browser.

Answer 2

This is basic for browser type detection but from this littel code its difficult to understand what going wrong.... Can u add body of isBrowser() that will help.

Answer 3

The best and shortest way to find the browser type for IE is.. U can do same for other browser types

if (navigator.appName == "Microsoft Internet Explorer"){

// Ur piece of validation 

}

Answer 4

A very good article on this comes from Quirksmode: http://www.quirksmode.org/js/support.html

The script supplied by 'lajuette' is good but it doesn't make you much smarter. The same author explain his thinking behind the script in the above link and basically what he says is:

• It is not about browser detection
• It is about object detection
• This leads to the knowledge of which browser is used.

Answer 5

I hope this helps:

(it's a long script, so i don't want to post it here)

Answer 6

function whereUWantToDetectBrowser(){
        if (navigator.appName == "Microsoft Internet Explorer")
        intExp();
        else
        other();

}
function intExp(){
        //do what you want to do for specifically Internet Explorer
}
function other(){
        //do what you want to do for other browsers
}

this code solves the problem. Instead of calling functions from whereUWantToDetectBrowser(), if you write your specific code there, this will cause an error. And code will not run. Because a browser detects the code which it has to run (specific to each browser). and if you are distinguishing the code means the code is not working in some browsers, so you want to write it specifically for those browsers. So, other() will have not effect in IE, as intExp() has no effect in other browsers.
