jQuery Autocomplete order of results

问题

I am using the jQuery-autocomplete plugin to get suggestions for completion of the input string using an AJAX call to a server. Also, the server takes care of returning the results in the order I would want them to appear but autocomplete shows them in a different order.

How can I configure jQuery autocomplete to not reorder the output ? I don't require any kind of processing on the client's end as the data has already been ranked/sorted as required.

回答1:

Simply sorting the server results before sending it to autocomplete should do it.

So before you echo json_encode($return_arr); use the sort() function on $return_arr

You can also try something like this:

The logic is to build up an array of matches that start with the term, and then concatenate that with matches that contain the term but don't start with it.

$(document).ready(function () {
    var source = ['Adam', 'Benjamin', 'Matt', 'Michael', 'Sam', 'Tim'];
    $("input").autocomplete({
        source: function (request, response) {
            var term = $.ui.autocomplete.escapeRegex(request.term)
                , startsWithMatcher = new RegExp("^" + term, "i")
                , startsWith = $.grep(source, function(value) {
                    return startsWithMatcher.test(value.label || value.value || value);
                })
                , containsMatcher = new RegExp(term, "i")
                , contains = $.grep(source, function (value) {
                    return $.inArray(value, startsWith) < 0 &&
                        containsMatcher.test(value.label || value.value || value);
                });

            response(startsWith.concat(contains));
        }
    });
});

Well, it turned out to be simpler than I thought. I decided to read the code of the plugin and modify it by commenting out the code that sorts my output.

That is when I found a variable 'sortResults:true' in defaults. So, all I needed was to set that variable to false. I didn't find this in the documentation though.

$('#search').autocomplete ( { url: "index.php", sortResults: false } )

Now the output is in the exact order that I require.

I got the idea of reading the code to find/solve the problem from here : jQuery "Autocomplete" plugin is messing up the order of my data (That isn't the same plugin)

Thanks. :)

Since there's no sortResults options in current build of jQuery Autocomplete plugin, I had to search another solution to this problem and found out the only reason the plugin is sorting result is that server response is being normalized everytime it's not a pure array with objects {label: ..., value: ...}.

Considering PHP as a language of your use, json_encode(array_values($your_array)); should do the trick.
