The list in Jquery UI Autocomplete is not updating correctly

Currently, I am using jQuery UI Autocomplete in conjunction with WebSockets to fetch and display a list of options. Each time a keystroke is detected on the input field (.keyup()), a call is made to retrieve the list. However, I have encountered an issue where after entering a character and fetching the corresponding list, the next keystroke continues searching within the previous list instead of the newly fetched one. The only way to refresh the list is by pressing backspace. How can I ensure that the list updates immediately without this workaround? Any assistance would be greatly appreciated.

UPDATE: Here is a snippet of the code: This section detects keystrokes and triggers the search

$('#pick_up_location').keyup(function(e) {
var param = $("#pick_up_location").val();                                  
var userType = "1";                                             
search(param, userType,"CBPickSearchAction", "", 0);                                                        

This part displays the received results in the autocomplete widget:

function onMessage(data) {
try {
    var obj = $.parseJSON(data);
    $("#pick_up_location").autocomplete({
             source: obj,
             minLength: 0,
             delay: 0,
             autoFocus: true,
             search: function() {},
             focus: function(event, ui) {
                event.preventDefault();
                return false;
              },
             open: function(event, ui){
                    $('#pick_up_location').autocomplete("widget").width(); 
             .data( "ui-autocomplete" )._renderItem = function(ul, item) {
            return $( "<li></li>" )
              .data( "item.autocomplete", item )
              .append( "<a>" + item.label + "</a>" )
              .appendTo( ul );
          };

          $("#pick_up_location").autocomplete('enable');
          $("#pick_up_location").keydown();
  } catch(err) {
        //console.log( err.message);
      }

Answer №1

After much trial and error, I finally managed to find a solution to my issue. The problem stemmed from the fact that typical autocomplete lists retrieve results from another domain using ajax calls. However, in my attempt to create a commercial application without relying on ajax, I encountered difficulties with the autocomplete feature. Moreover, I had set a self-imposed restriction of making API calls through a single websocket connection.

The breakthrough came when I decided to establish a new javascript connection to the Java websocket, utilizing its onmessage function to receive and populate the autocomplete response. Previously, the autocomplete's source was sourced from a variable containing pre-fetched results, leading to suboptimal functionality as it only searched through existing data without refreshing upon keystrokes.

Below is the revised code snippet:

function locationSearch() {
     $("#pick_up_location").autocomplete({
        source: function(request,response) {
            var action = "CBPickSearchAction";
            var userType = 1;
            var requestString = createRequestStringForLocationSearch(action, userType, request.term);
            webSocket_local.send(requestString);

            webSocket_local.onmessage = function(event) {
                data = event;
                data = formatLocationResponse(data, action);
            response($.parseJSON(data));
            };
        },
         minLength: 0,
         delay: 0,
         autoFocus: true,
            focus: function( event, ui ) {
                event.preventDefault();
                return false;
              },
              open    : function(event, ui){
                    $('#pick_up_location').autocomplete("widget").width(); 
            },
          .data( "ui-autocomplete" )._renderItem = function( ul, item ) {
            return $( "<li></li>" )
              .data( "item.autocomplete", item )
              .append( "<a>" + item.label + "</a>" )
              .appendTo( ul );
          };
}

$('#pick_up_location').keyup(function(e) {
       locationSearch();
}   

With this approach, I successfully eliminated the need for ajax in my web application. :)

If there are alternative solutions worth exploring, I'm eager to learn more about them.
