I'm sorry I thought it was best to tell where to find the error... On my page I include 'jquery-1.3.2.min.js', and the 'jquery.autocomplete.js' file.
I also include a file (search.autocomplete.php) that has list of words to autocomplete which looks like this "var autogemeenten = [ { text :'\'s-Hertogenbosch', url :'\'s- Hertogenbosch.html'}, { text :'Aa en Hunze', url :'Aa en Hunze.html'} ] ;" I'm using the following code to execute the auto complete and automatically redirect to the selected page. <script type="text/javascript"> $().ready(function() { $("#list-gemeente").autocomplete(autogemeenten, { matchContains: true, minChars: 2, formatItem: function(item) { return item.text; } }) .result(function(event, item) { location.href = item.url; }); }); </script> thanks again for your help
