Can you create an superclass of 2 javascript objects

Question

I have a base object class called coretype e.g.

 function coreotype(a,b,c){
    var coreA= a;
    var coreB= b;
    var coreC= c;
    function coreF(){...do something...}
    }

I then have a number of modification processes e.g.

function modifyA(m1){var md1 = m1; function mf(){...do something...}}

and

function modifyA(m1){var md1 = m1; function mf(){...do something...}}

I want to create super object classes of the core type and the 1 of the modification processes to create new object classes e.g. typeA which is an object class of coref + modifyA

so that I can define an object by doing something like:

var thing1 = new typeA(a,b,c,m1)

Is this possible? Also can these super classes be made using an interface so that I could remove say coreB from the resulting super class or am I just expecting more OOP than javascript can deliver? I would prefer an answer using javascript over jquery as I would really like to understand how it is being done. Thanks

not really a javascript guru, but you might want sometyhing like this modifyA.prototype = new coreotype; modifyB.prototype = new coreotype;.. — Vlad Otrocol

Thanks I got it working using your suggestion function coreotype(a,b,c){ this.coreA= a; this.coreB= b; this.coreC= c; function coreF(){} } function modifyA(m1){this.md1 = m1; function mf(){}} function modifyB(m1){var md1 = m1; function mf(){}} var typeA = modifyA var typeB = modifyB typeA.prototype = new coreotype(1,2,3); typeB.prototype = new coreotype(1,2,3); var thing1 = new typeA(1); var thing2 = new typeB(2); alert(thing1.coreB + thing2.coreC); — user1554759

check it out a post by John Resig about more robust Javascript Inheritance and OOP than the simple prototype: http://ejohn.org/blog/simple-javascript-inheritance/
