javascript - How to make custom date sort in datatables? -


i have table column of dates:

2015-03-03 20:14  2015-04-15 20:33  2015-04-20 09:34  2015-04-28 22:18

but cells have no date (i mark -). when using general sorting function looks like:

— — — 2015-03-03 20:14 2015-04-15 20:33 2015-04-20 09:34 2015-04-28 22:18

but need:

2015-03-03 20:14 2015-04-15 20:33 2015-04-20 09:34 2015-04-28 22:18 —  — —

actually, had sort 2 parameters , set rows without date in end of table. added 2 data attribute (status , date in timestamp format):

<tr>   <td><span class="label label-warning" data-status="0" data-date="1397562467">status 0</span></td>   <td>2015-03-03 20:14</td> </tr> <tr>   <td><span class="label label-warning" data-status="1" data-date="1397567321">status 1</span></td>   <td>2015-04-15 20:33</td> </tr> <tr>   <td><span class="label label-warning" data-status="0" data-date="1397567746">status 0</span></td>   <td>2015-04-20 09:34</td> </tr> <tr>   <td><span class="label label-warning" data-status="0" data-date="1397567321">status 0</span></td>   <td>2015-04-15 20:33</td> </tr>

i made new custom sort function:

jquery.fn.datatableext.osort['status-date-asc']  = function(x,y) {                  var xstatus, xdate, ystatus, ydate;                  xstatus = $(x).data('status');                 ystatus = $(y).data('status');                 xdate   = $(x).data('date');                 ydate   = $(y).data('date');                  return xstatus > ystatus ? 1                         : xstatus < ystatus ? -1                         : xdate > ydate ? 1                         : xdate < ydate ? -1 : 0;              };

and init row new sort function:

        var currenttable = $('#current_table').datatable( {              "aasorting": [ [5, 'asc'] ],             "aocolumns": [                 null,                 null,                 null,                 null,                 null,                 { "stype": 'status-date' },                 null,                 null,                 null             ],       });

finally, looks:

  • status 0, date = 2015-03-03 20:14
  • status 0, date = 2015-04-15 20:33
  • status 0, date = 2015-04-20 09:34
  • status 0, date = 2015-04-28 22:18
  • status 0, date = n/a
  • status 0, date = n/a
  • status 0, date = n/a
  • status 1, date = 2015-03-03 20:14
  • status 1, date = 2015-04-15 20:33
  • status 1, date = 2015-04-20 09:34
  • status 1, date = 2015-04-28 22:18
  • status 1, date = n/a
  • status 1, date = n/a
  • status 1, date = n/a
