问题
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="company" />
</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://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
});
});

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.
回答8:
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.
回答9:
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.
回答10:
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
},
回答11:
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.
回答12:
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();
}
}
