Sorts columns containing UTF8 Farsi numbers
- 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))
}
} );
