Is this what you want:

obj1.getName.call(obj2);

As @roland said, you can also use .apply(obj2, [arr of args]) if you want to provide an array of arguments to the method.

EDIT: If you want to import all obj1 methods into obj2, you can do that with pure JavaScript:

for (var m in obj1) {
    // if you want to copy obj1's attributes, remove this line
    if (obj1[m] instanceof Function) {
        obj[2][m] = obj1[m];
    }
}

Or you can do it with jQuery:

$.extend(obj2, obj1);

If are looking to use obj1 as a template for creating new objects, you can use Object.create to do this.

var obj1 = {
  name : 'honda',
  getName : function(){
   console.log(this.name);
  }
}

var obj2 = Object.create(obj1);
obj2.name = 'bob';
obj2.getName(); // outputs 'bob'
