Ultimate Date / Time sorting

Sort date and time in any format using Moment.js

• Author: Allan Jardine

This plug-in for DataTables represents the ultimate option in extensibility for sorting date / time strings correctly. It uses Moment.js to create automatic type detection and sorting plug-ins for DataTables based on a given format. This way, DataTables will automatically detect your temporal information and sort it correctly.

For usage instructions, please see the DataTables blog post that introduces it.

Plug-in code

(function (factory) {
    if (typeof define === "function" && define.amd) {
        define(["jquery", "moment", "datatables.net"], factory);
    } else {
        factory(jQuery, moment);
    }
}(function ($, moment) {

function strip (d) {
    if ( typeof d === 'string' ) {
        // Strip HTML tags and newline characters if possible
        d = d.replace(/(<.*?>)|(\r?\n|\r)/g, '');

        // Strip out surrounding white space
        d = d.trim();
    }

    return d;
}

$.fn.dataTable.moment = function ( format, locale, reverseEmpties ) {
    var types = $.fn.dataTable.ext.type;

    // Add type detection
    types.detect.unshift( function ( d ) {
        d = strip(d);

        // Null and empty values are acceptable
        if ( d === '' || d === null ) {
            return 'moment-'+format;
        }

        return moment( d, format, locale, true ).isValid() ?
            'moment-'+format :
            null;
    } );

    // Add sorting method - use an integer for the sorting
    types.order[ 'moment-'+format+'-pre' ] = function ( d ) {
        d = strip(d);
        
        return !moment(d, format, locale, true).isValid() ?
            (reverseEmpties ? -Infinity : Infinity) :
            parseInt( moment( d, format, locale, true ).format( 'x' ), 10 );
    };
};

}));

CDN

This plug-in is available on the DataTables CDN:

Note that if you are using multiple plug-ins, it is beneficial in terms of performance to combine the plug-ins into a single file and host it on your own server, rather than making multiple requests to the DataTables CDN.
