$ in JS.

Have you defined $ somewhere? Are you using the prototype framework?

That's what i wanted ...What is prototype framework?
Should it be installed separately?
Please clarify me!

If you just want to use the dollar function, then you don't need to include the whole prototype package which can be quite large.

You can define it yourself, e.g.

You can define it yourself, e.g. Code: ( text ) function $() {     var elems = [];     for (var i = 0; i < arguments.length; i++) {         var elem = arguments[i];         if (typeof elem == 'string')             elem = document.getElementById(elem);         if (arguments.length == 1)             return elem;         elems.push(elem);     }     return elems; }

I understand your point.
But whole prototype package where i can it?

All you had to do was search for it. Type "prototype" into your favourite search engine and hey presto! It's even included in the Offsite Links thread.

OK, I'm feeling generous. Here it is: http://www.prototypejs.org/.

Ok Thanks!
Basically who developed it?

Check out the site. It should have some info.
