Javascript associative array

Javascript does not feature associative arrays. However, you can create something similar using object arrays.

Example:

arr={'key1': 'value1','key2':'value2'};

This array can be accessed with:

the_value = array['key2']

Values can be added or changes:

arr['key3']='value3';

You can iterate over the object array using Jquery:

$.each( arr, function( index, value ){



    sum += value;



});
