Function to check a users browser v1.2

jsavagedesign

I though I'd share this with everyone.
Browser detection can help a lot with your web page and this function I have been working on will do just that.

I welcome any revisions to this that you can suggest.
Also, any bugs that need corrected.

The following function will return the users browser name, version, and their OS.

Enjoy!

    tn=nua.indexOf(ui[0])+ui[0].length+1;if(ui[0]==k[0]||ui[0]==k[1]|| ui[0]==k[2]){ui[1]=nua.substr(tn,3);

    }else if(ui[0]==k[3]){if(nua.charAt(tn)!="/"){ui[1]=nua.substr(tn,3);} else{tn+=1;ui[1]=nua.substr(tn,3);}

    if(nua.indexOf("Mac")!=-1){ui[2]="Macintosh";}else if(nua.indexOf("Windows")!=-1){ui[2]="Windows";}

    return ui.toString();

Heya, J.

Not to rain on your parade, but the generally-recommended method for checking to see if a browser supports an object, property or method is to use object detection.

You have a good browser-agent detection script, and there are uses for browser-agent detection.

Yeah, truthfully I haven't used this function much (but then again I don't do a lot of really advanced coding). But, if anyone needs to do this I though I'd help them out. Thanks for the artical link thou, that site has helped me a out a bunch in the past as-well.

I unually try to get a page to work universally, it just makes thinks easier. But, like recently, where a page with CSS styles will look perfect in all the other browsers but, Internet Explorer. After hours of trying to correct this I gave up and used something like this:

Expand|Select|Wrap|Line Numbers

 
var b = browserCheck();
 
if(b.indexOf("MSIE") == -1) {

    document.getElementById("greenDiv").style.marginLeft = '95px';

}

I know, not preatty but it makes the boss happy. :)
