Ever faced problem with native javascript not supporting Key-Value pair to store in an array and you may need variable indexing into your array?

By default, Arrays in javascript have only numeric indexing and its natively not possible to support an array with a string as index values.

The solution is to store key-value pair objects into the array and retrieve the value by calling a dedicated function.

Here is the code snippet:

//Script Include: Gears

var Gears = Class.create();
Gears.prototype = {
    initialize: function () {
        this.Weapons = []; //One weapon per level [{level : weapon},...]
    },

    _addWeapons: function (weapon, level) { //req type
        if (this._getWeapon(level) == '') {
            this.Weapons.push({
                level: level,
                weapon: weapon
            }); //Push the weapon key value pair in the array
        }
    },

    _getWeapon: function (level) {
        var weapon = '';
        for (i = 0; i < this.Weapons.length; i++) {
            if (this.Weapons[i].level == level) {
                weapon = this.Weapons[i].weapon;
            }
        }
        return weapon;
    },

    type: 'Gears'
}
