-

i have html textbox uses javascript autocomplete feature in jquery ui - v1.11.4. suggested string textbox concatenation of several columns (patient_no,patient_name,age , residence) table in database. wanted truncate part of string since require patient_no column placed in textbox.

possible text suggestion : '00032 >> tom michael >> 14yrs >> westlands'

what want placed in textbox : '00032'

below code

//html  <input name="patientno" id="patientno" type="text"   />     //autocomplete.php     $pat_no_seq_result = pg_query("select patient_no  || ' >> ' || surname || ' ' || other_name || ' >> ' || (current_date-year_of_birth)/365 || 'yrs' || ' >> '||residence hp_outpatient_register;");     $dname_list = array();     while ($row = pg_fetch_row($pat_no_seq_result)) {         $dname_list[] = $row[0] ;     }      //javascript   <script type="text/javascript">         $(function() {             var availabletags = <?php include('autocomplete.php'); ?>;             $("#patientno").autocomplete({                 source: availabletags,//autofocus: true                 select: function(event, ui) {                 getpatientno(ui.item.value);             }             });              function getpatientno(value) {             var patno = value.substring(0, value.indexof(' '));             document.getelementbyid("patientno").value = patno;         }         });     </script>
