Detect if IE7 & work around it? Help!

[Head In A Pan]

I'm trying to adapt an old piece of javascript to allow it to work with IE7 (which it wont... yet)

At the start of my js there is a line of code:

var ns = (navigator.appName.indexOf("Netscape") != -1);
which detects if netscape & makes some sort of rule (I am new at this - bear with me)

And in my searches for a IE7 equivalent I have found:
ie7=(this.ver.indexOf("MSIE 7")>-1 && this.dom)?1:0;

If this is the same sort of thing, how do I adapt it to my code?

Any suggestions?

Browser detection is not recommended, use object detection instead.

See this link - it gives you want you want, but read the object detection link.
