JQuery DataTable Column Filters With Delay Search Until 3+ Characters Or Enter Key

I'm try to achieve that, but so far not working. Tried those suggestion either in stackoverflow or datatables forum so far no luck yet. I tried the fnSetFilteringEnterPress of jQue

Solution 1:

Maybe this plugin might be of some help or give you an idea on how to continue:

Filter on Return

Add it to your script like this:

$(function() {
  $.fn.dataTableExt.oApi.fnFilterOnReturn = function(oSettings) {
    var _that = this;
    this.each(function(i) {
      $.fn.dataTableExt.iApiIndex = i;
      var $this = this;
      var anControl = $('input', _that.fnSettings().aanFeatures.f);
      anControl.unbind('keyup').bind('keypress', function(e) {
        //here's the part that you might need to modify:
        if (e.which == 13) {
          $.fn.dataTableExt.iApiIndex = i;
          _that.fnFilter(anControl.val());
        }
      });
      return this;
    });
    return this;
  };

  $('#datatable').DataTable({
    "oLanguage": {
      "sSearch": "Filter Data"
    },
    "iDisplayLength": -1,
    "sPaginationType": "full_numbers"
  }).fnFilterOnReturn();
});
