get

function

`scope.get(key [, options])`

Walks up the scope to find a value at key. Stops at the first context where key has a value.

scope.get("first.name");

Parameters

key {key}:
A dot seperated path. Use "." if you have a property name that includes a dot.

Returns

{*}:

The found value or undefined if no value is found.

Use

scope.get(key) looks up a value in the current scope's context, if a value is not found, parent scope's context will be explored.

var list = [{name: "Justin"},{name: "Brian"}],
    justin = list[0];

var curScope = new Scope(list).add(justin);

curScope.get("name"); //-> "Justin"
curScope.get("length"); //-> 2

Prefixing a key with "./" prevents any parent scope look ups. Prefixing a key with one or more "../" shifts the lookup path that many levels up.

var list = [{name: "Justin"},{name: "Brian"}];
list.name = "Programmers";
list.surname = "CanJS";

var justin = list[0];
var brian = list[1];
var curScope = new Scope(list).add(justin).add(brian);

curScope.get("name"); //-> "Brian"
curScope.get("surname"); //-> "CanJS"
curScope.get("./surname"); //-> undefined
curScope.get("../name"); //-> "Justin"
curScope.get("../surname"); //-> "CanJS"
curScope.get(".././surname"); //-> "undefined"
curScope.get("../../name"); //-> "Programmers"
