jQuery Autocomplete using extraParams to pass additional GET variables

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 be quite a few variations of this plugin.

I'm trying to pass additional parameters to the server when the user starts typing because I have multiple fields that I want autocomplete to provide suggestions for.

In addition to the query, I want to send the input name attribute to the server but I can't seem to use $(this).attr('name') within the extraParams.

My jQuery:

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

This is my HTML.

 <form method="post" action="#" id="update-form" autocomplete="off">
  <ol>
         <li class="ajax-auto">
             <label for="form-initials">Initials</label>
                <input type="text" id="form-initials" name="initials" />
            </li>
         <li class="ajax-auto">
             <label for="form-company">Company</label>
                <input type="text" id="form-company" name="comp开发者_C百科any" />
            </li>
  </ol>
 </form>

Any suggestions?

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://example.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
    });
});

Try this:

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

You can use the built in jquery ui autocomplete like so:

          $(function() {
         $("#BurroughName").autocomplete({
                minLength: 0,
                source: function( request, response) {
                            $.ajax({
                                        url: "/JsonData/GetBurroughFromSearchTermJson",
                                        dataType: "json",
                                        data: {
                                                    term: request.term,
                                                    CityId: $("#CityId").val()
                                        },
                                        success: function( data ) {
                                                    response( data );
                                        }
                            });
                },                  
                select: function( event, ui) {
                    $("#BurroughId").val(ui.item.id);

                    if (ui.item.id != null) {
                         var cityId = $('#CityId').val();
                        $.getJSON("/AdSales/City.mvc/GetCityJSONListFromBrand", { burroughId: ui.item.id }, function(data) {
                             $("#CityId").fillSelect(data);
                             var foo = $("#CityId option[value=" + cityId + "]");
                             if(($("#CityId option[value=" + cityId + "]").length > 0) && cityId != "")
                             {
                                 $("#CityId").val(cityId);
                             }
                        });
                    }
                    $('#burroughSpinner').fadeOut('slow', function(){});
                }
         });
     });

Here's their jsonp example: http://jqueryui.com/demos/autocomplete/#remote-jsonp

I had a similar Problem... don't know if it will work for you ....

I Tried

 $("#awbCusName").autocomplete("getOracleCus.php?",{
  extraParams: {
  ZONE: function() { return $("#awbZone").val(); }, 
  SE: function() { return $("#awbSE").val(); }, 
  WSC: function() { return $("#awbWSC").val(); } 
 },
delay:200,
selectOnly:true,
cacheLength:0,
autoFill:true,
matchSubset:true,
minChars:1
});

CACHELENGTH:0 did the trick

Thanks

While less than ideal, I've hacked/modified the plugin to get it to work for me.

Simply, I've altered the AJAX jQuery function within the plugin.

Around line 363 you'll see:

        $.ajax({
            // try to leverage ajaxQueue plugin to abort previous requests
            mode: "abort",
            // limit abortion to this input
            port: "autocomplete" + input.name,
            dataType: options.dataType,
            url: options.url,
            data: $.extend({
                q: lastWord(term),
                search_type: $(input).attr('name'), // my mod to pickup multiple fields
                limit: options.max
            }, extraParams),
            success: function(data) {
                var parsed = options.parse && options.parse(data) || parse(data);
                cache.add(term, parsed);
                success(term, parsed);
            }
        });

I'm still looking for an elegant solution to this so feel free to keep suggestions coming.

jQuery( "#jac" ).autocomplete({
    source: autocompleteURL,
    minLength: 2,
    search: function( event, ui ) { 

        // update source url by adding new GET params
        $(this).autocomplete( 'option', 'source', autocompleteURL + 'var1=aaa&var2=bbb' );
    }
})

Works for me with jquery.ui.autocomplete 1.8.17

Using the autocomplete in JQuery 1.7.something...

Using an aspx data grid: I needed autocomplete to fire for any record choosen but with different seed data based on the value entered. I also needed two other fields that are being displayed in the record on the data grid to get my data for the autocomplete. The fields I need to reference all have their own class name.

    $(".AutoSearch").autocomplete({
            DateTime: "",
            Maker: "",
            search: function (event, ui) {
                DateTime = $(this).parent().parent().parent().find(".DateTime").text();
                Maker = $(this).parent().parent().parent().find(".Maker").text();
            },
            source: function (request, response) {
                $.ajax({
                    type: "POST",
                    dataType: "json",
                    url: "AutoList.aspx/GetListOfAutos",
                    data: "{ " +
                        "'DateTime': '" + DateTime + "', " +
                        "'Maker': '" + Maker + "', " +
                        "'SearchSeed': '" + request.term + "', " +
                        "'NumberToRetrieve': '" + 100 + "'" +
                    " }",
                    contentType: "application/json; charset=utf-8",
                    success: function (data) {
                        response($.map(data.d, function (item) {
                            return {
                                label: item.Description,
                                value: item.Number
                            }
                        }));
                    },
            error: function (XMLHttpRequest, textStatus, errorThrown) {
                        alert("There was an error retrieving the Data.");
                    }
                });
            },
            change: function (event, ui) {
                $(this).parent().parent().parent().parent().parent().parent().css("background-color", "#EEC900");
                $(this).parent().parent().parent().parent().parent().parent().find(".chkReadyExport").find("input:checkbox").prop("checked", false);
            },
            select: function (event, ui) {
                this.value = ui.item.value;
                return false;
            },
            minlength: 6,
            open: function () {
                $(this).removeClass("ui-corner-all").addClass("ui-corner-top");
            },
            close: function () {
                $(this).removeClass("ui-corner-top").addClass("ui-corner-all");
            }
        });
    }

I added two properties; DateTime and Maker and then using search: which is fired before the autocomplete fires source: I was able to get the data I needed from the row that I was on. This provided me a nice way to keep all my searching and extra data items all in one place.

The .parent().parent() and so on is because I have multi-line tables to display my data in the gridview and I need to traverse up the tree and then find the text box or label I'm looking for and change the background color of the row with the changed data. I am not proficient at finding items with jQuery yet thus the parent.parent... thing.

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.

I am not sure why it is not working.

But you can first check/debug for value of $(this).attr('name').

Also one more thing as here explained [in options tab], you can check with Firebug to see ajax post request(for url and it's data) which will help you to resolve the problem.

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
                },

I had the same problem, but oddly enough, only with the minified version of the autocomplete plugin. When I used the non-minified version, it works. I haven't looked at the minified version yet to see what the difference might be.

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 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);

                                response(CRM.$.map(result, function (val,key) {
                                                         //console.log(key);

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

/**

    $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( ) ) {
