obj.doSomething = function()
{
  console.log('done');
}

obj.doSomething();

This won't affect any of obj's existing fields or methods (the obvious exception being if there's already a doSomething).

var myFunc = function() { ... };
var myObj = { func: myFunc };

myObj.func();

You can also skip the myFunc temporary variable if you want to.

Pretty vague, but here you go:

var obj = {};
obj.foo = function() {
    return "baz";
};

// code...

obj.foo();
