You need to keep a reference to this from inside t if you want to access it within a.func . Try the following:

var t = function(){
    var this_t = this; // Use this_t to access this.p and this.function1 inside a

    this.p=0;
    this.function1 = function(){

    }

    var a=new ob();
    a.func = function(){//overrides the func

        this_t.p = 1;
        this_t.function1();

    }

};
