  • I understand that its been answered already. but I hope this will help someone in future and saves so much time and pain.

    complete code is below: This one I did for a textbox to make it Autocomplete in CiviCRM. Hope it helps someone

    CRM.$( 'input[id^=custom_78]' ).autocomplete({
                autoFill: true,
                select: function (event, ui) {
                        var label = ui.item.label;
                        var value = ui.item.value;
                        // Update subject field to add book year and book product
                        var book_year_value = CRM.$('select[id^=custom_77]  option:selected').text().replace('Book Year ','');
                        //book_year_value.replace('Book Year ','');
                        var subject_value = book_year_value + '/' + ui.item.label;
                        CRM.$('#subject').val(subject_value);
                        CRM.$( 'input[name=product_select_id]' ).val(ui.item.value);
                        CRM.$('input[id^=custom_78]').val(ui.item.label);
                        return false;
                },
                source: function(request, response) {
                    CRM.$.ajax({
                        url: productUrl,
                            data: {
                                            'subCategory' : cj('select[id^=custom_77]').val(),
                                            's': request.term,
                                        },
                        beforeSend: function( xhr ) {
                            xhr.overrideMimeType( "text/plain; charset=x-user-defined" );
                        },
    
                        success: function(result){
                                    result = jQuery.parseJSON( result);
                                    //console.log(result);
                                    response(CRM.$.map(result, function (val,key) {
                                                             //console.log(key);
                                                             //console.log(val);
                                                             return {
                                                                     label: val,
                                                                     value: key
                                                             };
                                                     }));
                        }
                    })
                    .done(function( data ) {
                        if ( console && console.log ) {
                         // console.log( "Sample of dataas:", data.slice( 0, 100 ) );
                        }
                    });
                }
      });
    

    PHP code on how I'm returning data to this jquery ajax call in autocomplete:

    /**
     * This class contains all product related functions that are called using AJAX (jQuery)
     */
    class CRM_Civicrmactivitiesproductlink_Page_AJAX {
      static function getProductList() {
            $name   = CRM_Utils_Array::value( 's', $_GET );
        $name   = CRM_Utils_Type::escape( $name, 'String' );
        $limit  = '10';
    
            $strSearch = "description LIKE '%$name%'";
    
            $subCategory   = CRM_Utils_Array::value( 'subCategory', $_GET );
        $subCategory   = CRM_Utils_Type::escape( $subCategory, 'String' );
    
            if (!empty($subCategory))
            {
                    $strSearch .= " AND sub_category = ".$subCategory;
            }
    
            $query = "SELECT id , description as data FROM abc_books WHERE $strSearch";
            $resultArray = array();
            $dao = CRM_Core_DAO::executeQuery( $query );
            while ( $dao->fetch( ) ) {
                $resultArray[$dao->id] = $dao->data;//creating the array to send id as key and data as value
            }
            echo json_encode($resultArray);
        CRM_Utils_System::civiExit();
      }
    }

    You need to transform the object you are getting back into an array in the format that jQueryUI expects.

    You can use $.map to transform the dealers object into that array.

    $('#dealerName').autocomplete({
        source: function (request, response) {
            $.getJSON("/example/location/example.json?term=" + request.term, function (data) {
                response($.map(data.dealers, function (value, key) {
                    return {
                        label: value,
                        value: key
                    };
                }));
            });
        },
        minLength: 2,
        delay: 100
    });
    

    Note that when you select an item, the "key" will be placed in the text box. You can change this by tweaking the label and value properties that $.map's callback function return.

    Alternatively, if you have access to the server-side code that is generating the JSON, you could change the way the data is returned. As long as the data:

    • Is an array of objects that have a label property, a value property, or both, or
    • Is a simple array of strings

    In other words, if you can format the data like this:

    [{ value: "1463", label: "dealer 5"}, { value: "269", label: "dealer 6" }]
    

    or this:

    ["dealer 5", "dealer 6"]
    

    Then your JavaScript becomes much simpler:

    $('#dealerName').autocomplete({
        source: "/example/location/example.json"
    });

    I use this script for autocomplete...

    $('#custmoers_name').autocomplete({
        source: function (request, response) {
    
            // $.getJSON("<?php echo base_url('index.php/Json_cr_operation/autosearch_custmoers');?>", function (data) {
              $.getJSON("Json_cr_operation/autosearch_custmoers?term=" + request.term, function (data) {
              console.log(data);
                response($.map(data, function (value, key) {
                    console.log(value);
                    return {
                        label: value.label,
                        value: value.value
                    };
                }));
            });
        },
        minLength: 1,
        delay: 100
    });
    

    My json return :- [{"label":"Mahesh Arun Wani","value":"1"}] after search m

    but it display in dropdown [object object]...
