[jQuery] extend an Object

[jeanluca]

Hi All

I tried to add functions to an object like

     function User(n, a) {
         this.name = n ;
        this.aux = a ;
     }
     function auxis() {
       alert(this.aux);
     }

       $(document).ready( function() {
         var u = new User("Jack") ;
         u.extend({
             whoami: function() { alert(this.name); },
            autis: auxis
         }) ;
         u.whoami() ;
}) ;

Eventually I will have 2 object A and B and I want to merge A into B:

    B.exend(A) ;

However it doesn't work at all. Any suggestions how to fix this ?
