jquery autocomplete renderItem

Question

I have the following code. It generates no js errors. Can't get the autocomplete to display any results:

$(function() {
    $.ajax({
    url: "data.xml",
    dataType: "xml",
    cache: false,
    success: function (xmlResponse) {
        var data_results = $("Entry", xmlResponse).map(function () {
            return {
                var1: $.trim($("Partno", this).text()),
                var2: $.trim($("Description", this).text()),
                var3: $.trim($("SapCode", this).text()),
                var4: $("Title", this).text(),
                var5: $.trim($("File", this).text()),
                var6: $.trim($("ItemID", this).text())
            };
        }).get();

        $("#searchresults").autocomplete({
            source: data_results,
            minLength: 3,
            select: function (event, ui) {
                ...
            }
        }).data( "autocomplete" )._renderItem = function( ul, item ) {
                return $( "<li></li>" ).data("item.autocomplete", item)
                    .append( "<a>" + item.var1 + "<br>" + item.var2 + "</a>")
                    .appendTo( ul );
        };

    }
});

Any ideas what I might be missing? Thanks in advance.

It seems that .data('autocomplete') is now .data('ui-autocomplete').

By default, autocomplete expects your source array to contain objects with either a label property, a value property, or both.

With that in mind you have two options:

1. Add a label or value property to your source objects when you process the array from your AJAX call:

   var data_results = $("Entry", xmlResponse).map(function () {
       return {
           var1: $.trim($("Partno", this).text()),
           var2: $.trim($("Description", this).text()),
           var3: $.trim($("SapCode", this).text()),
           var4: $("Title", this).text(),
           var5: $.trim($("File", this).text()),
           var6: $.trim($("ItemID", this).text()),
           value: $.trim($("Description", this).text())
       };
   }).get();
   

   The value you assign will be used on focus, select, and to search on.

2. Change the source function to perform custom filtering logic:

   $("#searchresults").autocomplete({
       source: function (request, response) {
           var matcher = new RegExp($.ui.autocomplete.escapeRegex(request.term), "i");
   
           response($.grep(data, function (value) {
               return matcher.test(value.var1) || 
                      matcher.test(value.var2);
               /* etc., continue with whatever parts of the object you want */
           }));
       },
       minLength: 3,
       select: function (event, ui) {
           event.preventDefault();
           this.value = ui.var1 + ui.var2;
       },
       focus: function (event, ui) {
           event.preventDefault();
           this.value = ui.var1 + ui.var2;
       }
   }).data( "autocomplete" )._renderItem = function( ul, item ) {
           return $( "<li></li>" ).data("item.autocomplete", item)
               .append( "<a>" + item.var1 + "<br>" + item.var2 + "</a>")
               .appendTo( ul );
   };
   

   Note that with this strategy you have to implement custom select and focus logic.
