Hi.

I read jQuery core.js(1.5) last month with my friends who love it. :-)

We were not sure what is the code of "jQuerySubclass.subclass = this.subclass;" in the jQuery.sub method.

How can I use it and what is the meaning of this substitution.

I checked unit test of core.js, but I have no idea.

If I don't set any value to jQuery.subclass, subclass property of the sub-class is undefined.

1. var subClass = $.sub();
2. subClass.subclass; // => undefined
3. subClass.subclass = "subClassName";
4. var subsubClass = subClass.sub()
5. subsubClass.subclass // => "subClassName"
6. var subsubsubClass = subsubClass.sub()
7. subsubsubClass.subclass // => "subClassName"

What is the advantage of subclass property ?

Best regards.
