Javascript: How to get current object value in an associative array?

Question

var obj = {
    "key": "some",
    "foo": function() {return obj.key; // key undefined}
}

is there a way to get the reference to key inside the function?

Answer 1

Probably. If foo is called as obj.foo() , you'll be able to use this.key . However, obj should not be undefined at that point; if you're changing it later and don't want to rely on this , you can keep it in a different scope:

var obj = (function () {
    var obj = {
        key: "some",
        foo: function () { return obj.key; }
    };

    return obj;
})();
