• Author: [Behrooz Janfada](behrooz dot janfada at gmail com)

Sorts a column containing Farsi numbers. Farsi numbers can easily be mapped 1:1 to latin numbers - ۱ = 1, ۲ = 2, ۱۲ = 12 and so on.

Plug-in code

jQuery.extend( jQuery.fn.dataTableExt.oSort, {
    "farsi-numbers-pre" : function(a) {
        function farsiToLatin(farsi) {
            switch(farsi) {
                case "۰": return 0; break;
                case "۱": return 1; break;
                case "۲": return 2; break;
                case "۳": return 3; break;
                case "۴": return 4; break;
                case "۵": return 5; break;
                case "۶": return 6; break;
                case "۷": return 7; break;
                case "۸": return 8; break;
                case "۹": return 9; break;        
                default : return 0; break;
            }        
        }
        var latin = '', i = 0;
        for (i; i<a.length; i++) {
            latin += farsiToLatin(a.charAt(i))
        }
        return parseInt(latin)
    },

    "farsi-numbers-asc": function(a, b) {
        return ((a < b) ? -1 : ((a > b) ? 1 : 0))
    },

    "farsi-numbers-desc": function(a, b) {
        return ((a < b) ? 1 : ((a > b) ? -1 : 0))
    }

} );
