<script type="text/javascript">
    $('#search').autocomplete({
        source: function(req, add){  

            //pass request to server  
            $.getJSON("suggest.php?callback=?", req, function(data) {  

                //create array for response objects  
                var suggestions = [];  

                //process response  
                $.each(data, function(i, val){  
                suggestions.push(val.lable+' '+val.value+' '+val.both);  
            });  

            //pass array to callback  
            add(suggestions);  
            });  
        },  
        select: function(e, ui) {
        $('#search').val(ui.item.lable);
        },
        width: 300,
        max: 10,
        delay: 50,
        minLength: 1,
        scroll: false,
        highlightItem: true
      });
    </script>

server respond

([{"lable":"apartamentos mojácar beach","value":"mojacar","both":"spain"},{"lable":"hotel mandakini grand","value":"new delhi","both":"india"},{"lable":"hotel sol y mar sharming inn","value":"sharm el sheikh","both":"egypt"},{"lable":"la quinta inn and suites sarasota","value":"sarasota","both":"usa"},{"lable":"ocean sand golf and beach resort","value":"punta cana","both":"dominican republic"},{"lable":"rooms barcelona","value":"barcelona","both":"spain"},{"lable":"villa maroc essaouira","value":"essaouira","both":"morocco"},{"lable":" il casale farmhouse with panoramic swimming poo","value":"bettona","both":"italy"},{"lable开发者_开发知识库":" shelley's ","value":"lynton","both":"united kingdom"},{"lable":" 1 melrose blvd by seasons in africa","value":"johannesburg","both":"south africa"}]);

i know the problem is in "SELECT" and "SOURCE" field of autocomple but i dont know how to work with it. how to parse the respond so it can work. it work with only one field but not with 4 fields(vars)

ok now i can get 3 virables from the server i add them in the source. but i cant select only one all the time it select all the string! how can i manage that?

If you want to use jquery ui autocomplete, your data must be "a simple Array of Strings, or it contains Objects for each item in the array, with either a label or value property or both". This is from the documentation at http://jqueryui.com/demos/autocomplete/

Your server response does not follow the expected data type, you should modify suggest.php to post-process the data into label-value pairs.

As I understand it, you also want to perform a custom action when an item is selected from the autocomplete, so you should also add a handler for the 'select' event.

I don't understand. In what way does your code not work? What does suggest.php look like? If suggest.php is a list of strings formated as you wish it should work fine.
