jQuery Autocomplete using extraParams to pass additional GET variables

Question

I am referring specifically to the jQuery Autocomplete v1.1 plugin by Jörn Zaefferer [source: http://bassistance.de/jquery-plugins/jquery-plugin-autocomplete/] as there seems to

Answer 1

With regards to the most voted answer, I think there is a much simpler syntax by just appending the extra request value into the source url.

This:

$("#city_id").autocomplete({
    source: src+"?country_id="+$("#country_id").val().
    min_length: 3,
    delay: 300
});

does the same as:

$("#city_id").autocomplete({
    source: function(request, response) {
        $.ajax({
            url: src,
            dataType: "json",
            data: {
                term : request.term,
                country_id : $("#country_id").val()
            },
            success: function(data) {
                response(data);
            }
        });
    },
    min_length: 3,
    delay: 300
});

given that src is an url string.

Answer 2

use a .each first, then you can use $(this) and set whatever you need into a variable. the resulting variable can be used in the autocomplete

$(".autosuggest").each(function (index, object) {
    var autosuggestType = $(this).attr("autoSuggestType");
    $(this).autocomplete("url",
            {                    
                extraParams: {
                    autoSuggestType: autosuggestType
                },

Answer 3

Try this:

$('.ajax-auto input').setOptions({
  extraParams: {
    search_type: function(){
      return $(this).attr('name');
    }
  }
})

I am using the autocomplete function that is now part of jquery ui. Passing an 'extraParams' field does not work but you can just append the values in the request query string.

$(document).ready(function() {
    src = 'http://domain.com/index.php';

    // Load the cities straight from the server, passing the country as an extra param
    $("#city_id").autocomplete({
        source: function(request, response) {
            $.ajax({
                url: src,
                dataType: "json",
                data: {
                    term : request.term,
                    country_id : $("#country_id").val()
                },
                success: function(data) {
                    response(data);
                }
            });
        },
        min_length: 3,
        delay: 300
    });
});

Answer 5

Try with

$( "#ricerca" ).autocomplete({
                source: "response.php?param=param",
                minLength: 2
});

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

(you can replace 'CRM.$' with '$' or 'jQuery' depending on your jQuery version)

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();
  }
}
