javascript - DataTables - Ignore empty moment date values when sorting -


i'm using datatables , trying ignore empty values on date column based momentjs when sorting.

e.g: 08 nov 2016 09:47 pm

http://codepen.io/anon/pen/qqbwva?editors=1010

currently have , sorts values expected contains empty cells. 

$.fn.datatable.moment('dd mmm yyyy hh:mm a'); $('.table-data').datatable();

i've tried following custom sorting method posted here https://datatables.net/forums/discussion/1178/sorting-dates-handling-null-values

jquery.extend(jquery.fn.datatableext.osort, {     'date-asc': function (a, b) {       var x = date.parse(a);       var y = date.parse(b);       if (x == y) { return 0; }       if (isnan(x) || x < y) { return 1; }       if (isnan(y) || x > y) { return -1; }     },     'date-desc': function (a, b) {       var x = date.parse(a);       var y = date.parse(b);       if (x == y) { return 0; }       if (isnan(y) || x < y) { return -1; }       if (isnan(x) || x > y) { return 1; }     } });  $('.table-data').datatable({     columndefs: [       { type: 'date', targets: -1 }     ] });

but seems no difference. appreciate if sort issue.

update want move empty valued row last won't visible @ first place. http://jsfiddle.net/dnsl2oc4/2/

try instead:

$(document).ready(function() {   //$.fn.datatable.moment('dd mmm yyyy hh:mm a');   jquery.extend(jquery.fn.datatableext.osort, {     'datenonstandard-asc': function (a, b) {       var x = date.parse(a);       var y = date.parse(b);       if (x == y) { return 0; }       if (isnan(x) || x < y) { return 1; }       if (isnan(y) || x > y) { return -1; }     },     'datenonstandard-desc': function (a, b) {       var x = date.parse(a);       var y = date.parse(b);       if (x == y) { return 0; }       if (isnan(y) || x < y) { return -1; }       if (isnan(x) || x > y) { return 1; }     }   });   $('.table-data').datatable({     columndefs: [       { type: 'datenonstandard', targets: -1 }     ]   }); });

if you're doing non-standard sorting it'd better clear ;-)

it seems want , think logic sound using moment overkill. might need test more, though...
