[jQuery] extend an Object

[jQuery] extend an Object


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 ?
