Table Date Column Sort with Jquery

Some time we want to sort date filed in a Table with Jquery.

Here I add a parser in ready function.

$(document).ready(function () {

            $.tablesorter.addParser({

                id: 'dateMS',

                is: function (s) {// return false so this parser is not auto detected

                    return false;

                },

                format: function (s) {

                    var mydate = s; // here my date Formate is yyyy-MM-dd we know that javaScript default format is MM/dd/yyyy so I am converting date filed in a (MM/dd/yyyy) format.

                    var datecal = mydate.split('-')[1].toString() + "/" + mydate.split('-')[2].toString() + "/" + mydate.split('-')[0].toString();

                    var d = Date.parse(datecal);

                    if (isNaN(d)) {

                        return -1;

                    }

                    return d;

                },

                // set type, either numeric or text

                type: 'numeric'

            });

            $("#TblActiveCases").tablesorter({ sortList: [[0, 0]], textExtraction: "complex", widthFixed: false, dateFormat: 'YYYY-mm-dd',

                headers: { 1: { sorter: 'dateMS' }, 2: { sorter: false} }

            })

        });
