Question

This has been bugging me for quite some time now. All I want to do is return a value from an array given its key, but use a variable (_interview) to choose what array to return from.

var utils = function () {

var _language = "";
var _interview = "";
var _base = "";

var _alerts = function (code) {

    var en = new Array(),
        fr = new Array();

    en[0] = "You must enter a value in the box before continuing.";
    fr[0] = "Vous devez entrer une sélection pour les options mises en évidence.";

    // I know _interview is returning the correct value of either "en" or "fr"
    // I have tried this[_interview][code] but I get property not defined at the index
    // How do I return the index from the right array?
};

return {

    lang : function () {

        _language = $("#language option:selected").val();
        var answer = confirm(_alerts(0)); // Call from here

    }
};
}();

$(document).ready(function ()
{
    utils.lang();
});

Better to use 2D Array (deep object structure), and strings as keys instead of integer indexes

var languages = {
    'en': {
        'string_key_1' : 'String For Key 1'
    },
    'fr': {
        'string_key_1' : 'Le String ...'
    }
};

To get values like

var key = 'string_key_1';
var translated_value = languages[_interview][key];
