So I came up with this script that ajax calls google's suggestions and JSONP returns the search results. I managed to make the results sorted but I'd like to implement jquery autocomplete instead. I've tried any possible way I could think of but haven't got any results.

Here is the a working fiddle: http://jsfiddle.net/YBf5J/ and here is the script:

$(document).ready(function() {      
    $('#q').keyup(retrieve);
    $('#q').focus();
    $('#results').show('slow');



    $("#q").autocomplete(parse, {
    Height:100,
    width:620,
    noCache: false,
    selectFirst: false
    });
});    


function retrieve() {
    $.ajax({
        type: "GET",
        url: 'http://suggestqueries.google.com/complete/search?qu=' + encodeURIComponent($('#q').val()),
        dataType: "jsonp",
        jsonpCallback: 'parse'
    });    
}



var parse = function(data) {
    var results = "";
    f开发者_开发知识库or (var i = 0; i < data[1].length; i++) {
        results += '<li>' + '<a href="#">' + data[1][i][0] + '</a>' + '</li>';
    }

    $('#results').html('' + results + '');
    $('#results > li a').click(function(event) {
        event.preventDefault();
        $('#q').val($(this).html()).closest('form').submit();
    });

}

And here's the simple body:

<body><input type="text" id="q"><div id="results"></div></body>

Any help is really appreciated. Thanks alot, rallyboy.

Here is an example of using the Jquery-UI Auto complete. Taken from your code, all i did was update the auto complete source every time the data changes using this code.

var parse = function(data) {
var results = [];
for (var i = 0; i < data[1].length; i++) {
     results.push(data[1][i][0]);
}
$('#q').autocomplete({
    source: results
});

See fiddle

It uses just the base CSS but that can be changed by pointing it at which ever theme you want.
