how to change jQuery autocomplete plugin default querystring key? (term to that i want)

jQuery autocomplete plugin sent request like this

is there any way to change term querystring key to another? i can't find option that provide this for me ;)


I assume you're using jQuery UI AutoComplete

You need to provide a callback as the source, like this:

    source: function(term, callback) {
        $.getJSON("url", { foo: term }, callback);

The above is not correct for the current release (1.8.6). Not sure if it ever was...

  source: function(request, response) {
    $.getJSON("url", { foo: request.term }, response);

foo: being the new param key name..

Actually I dug up the code that the plugin uses. Adapting it to change the term would be something like this:

    source: (function() {
        var xhr;
        return function(request, response) {
            if (xhr) {
            xhr = $.ajax({
                url: '',
                data: {
                    foo: request.term
                dataType: 'json',
                success: function(data) {
                error: function() {

I would say this has 2 advantages:

  1. Abort pending requests
  2. Call the response with an empty set in case of error, which seems more polite to me
