php - how to use select method with auto complete? -

code:

<script> $(function() {     $( "#college_name" ).autocomplete({         source: 'search.php',         minlength:2,         select: function(event, ui) {     var x = ui.item.value;     $("#college_name").attr('value',x);     }     }); }); </script>  <script>    $(document).ready(function(){        $("#college_name").select(function(){           alert("hi");        });    }); </script> 

html code:

<input type="text" id = "college_name"  name = "college_name" value="" placeholder = "college name" autocomplete="off"> <input type='text' name='college_id' id='college_id'>

add alert message in select event of autocomplete.

 <script>     $(function() {         $( "#college_name" ).autocomplete({             source: 'search.php',             minlength:2,             select: function(event, ui) {         var x = ui.item.value;         $("#college_name").attr('value',x);          alert("hi");         }         });     });     </script>
