Datatables filter numbers greater than

Question

I am using datables, I need to filter particular column whose values are greater than 50 , I tried below code , but nothing happens

oTable.api().column( 10 )
           


        

Answer 1

"Nothing happens" because nothing is expected to happen. filter() should be used to create internal datasets or extract subsets of data - if you want to filter the rows in the table you should use a custom filter. It could look like this :

$.fn.dataTable.ext.search.push(function(settings, data, dataIndex) {
  return data[10] > 50 //type conversion is not necessary
})

This works as a "master" filter before .search() (and other filters). If you want to remove the filter you can use $.fn.dataTable.ext.search.pop(). So

1. $.fn.dataTable.ext.search.push( filter function )
2. table.draw()
3. $.fn.dataTable.ext.search.pop()

Answer 2

If you want to check any number greater than 5 then you can write ternary conditional with the hidden column in dataTable. Using filter add MORETHAN5RECORD as a value in the select dropdown to filter greater than 5 records.

Here is the Code :
var table = $('#record_table').DataTable({});
$('.FILTERCLASS').on('keyup change', function () {
		buildFilters(table,this);
});	
	
function buildFilters(table, element){					
    var type = $(element).data('type'),
        col = $(element).data('col'),
        id = $(element).id;   
      table
          .column( col )
          .search( element.value )
          .draw();
    }

 <td><?php 
echo (($row['xyz'] >= 5) ? $val['xyz']."(MORETHAN5RECORD)" : $val['xyz']); ?> </td>
