  filtering: function(e) {
      //get filter descriptor
      var filter = e.filter;
/* The result can be observed in the DevTools(F12) console of the browser. */

function autocomplete_filtering(e) {

  var filter = e.filter;
/* The result can be observed in the DevTools(F12) console of the browser. */
  console.log(filter);

  // handle the event

  filtering: function(e) {
      var filter = e.filter;

      if (!filter.value) {
        //prevent filtering if the filter does not value
        e.preventDefault();
      }
  }
});
</script>
