I have very generic javascript code for autocomplete. Everything works fine, but when You type:
Manner
You will have result:
Manner
Männer
In database i have words with special letters, but in case "manner" i dont want to show word with letter "ä" - as this dont fit to result to me.
How can i ignore results like this ?
Thank You for any advice.
The code:
$(document).ready(function () {
if ($('#tags').length <= 0) {
return;
}
var $project = $('#tags');
$project.autocomplete({
minLength: 2,
source: function (request, response) {
$.ajax({
dataType: "json",
type: 'post',
cache: false,
data: {term: request.term},
url: '/ajax/',
success: function (data) {
response($.map(data, function (item) {
return {
label: item.Cities__zip,
value: item.Cities__zip
}
}));
}
});
},
});
});
This looks to like something that would be better to handled server rather than client side. But if you want to do it in the ajax call you could do something like this, which utilizes a regular expression to match non-English characters, and filters those items out:
$(document).ready(function () {
if ($('#tags').length <= 0) {
return;
}
var $project = $('#tags');
$project.autocomplete({
minLength: 2,
source: function (request, response) {
$.ajax({
dataType: "json",
type: 'post',
cache: false,
data: {term: request.term},
url: '/ajax/',
success: function (data) {
response($.map(data, function (item) {
return (/[^\u0000-\u007F]+/).test(item.Cities__zip) ? null :
{
label: item.Cities__zip,
value: item.Cities__zip
}
}));
}
});
},
});
});

I am getting response through autofill which i can view through inspect in chrome. But I couldn't display properly neither i am getting any result in console.log
$(document).ready(function(){
$(function() {
$("#search_text").autocomplete({
source: "/find_city",
minLength: 1,
data:$('#search_text').val(),
success:function(data){
console.log(data);
}
});
});
})
Your source must be your ajax request
source: function (request, response) {
$.ajax({
url: "/find_city",
data: $('#search_text').val(),
dataType: "json",
success: function (data) {
// do something
}
});
}
and in your callback just return assign your desired value and label for the select input option element(s)
response($.map(data, function (item) {
return {
label: item.name,
value: item.name
}
}));
So you code would be like this
source: function (request, response) {
$.ajax({
url: "/find_city",
data: $('#search_text').val(),
dataType: "json",
success: function (data) {
response($.map(data, function (item) {
return {
label: item.name,
value: item.name
}
}));
}
});
}
I have found solution to my issue. I have changed name field from cities table to value and it works like a charm. I could also use key field
i used jqueryui autocomplete iwant be the same work for some input text
but when i use $(this).val() for send value of textbox it show error and when i use (".Degree").val() shows and send to server first textbox it incorrect
function DegreeAutoComplete() {
$(".Degree").autocomplete({
position: { my: "right top", at: "right bottom", collision: "none" },
source: function (request, response) {
var spin = $(".spinnerDegree");
spin.addClass("fa-spin fa-spinner");
$.ajax({
url: "#Url.Action("GetDegree")",
type: "POST",
dataType: "json",
data: { search: $(".Degree").val() },
success: function (data) {
spin.removeClass("fa-spin fa-spinner");
response($.map(data, function (item) {
return { label: item.PersianName, value: item.PersianName, id: item.Id };
}));
}
});
},
messages: {
noResults: '',
results: function (resultsCount) { }
},
select: function (event, ui) {
// ui.item.value contains the id of the selected label
alert($(this).val());
$(this).attr("sel", ui.item.id);
}
});
}
when i use: $(this).val();
elem.nodeName is undefined
hooks = jQuery.valHooks[ elem.type ] || jQuery.valHooks[elem.nodeName.toLowerCa...
how can i fix it
this refers to ajax object inside it. Save this reference before using it in inside scope.
var spin = $(".spinnerDegree");
spin.addClass("fa-spin fa-spinner");
var $that = $(this);// save reference
$.ajax({
url: "#Url.Action("
GetDegree ")",
type: "POST",
dataType: "json",
data: { search: $that.val() },//use $that var here
success: function(data) {
spin.removeClass("fa-spin fa-spinner");
response($.map(data, function(item) {
return { label: item.PersianName, value: item.PersianName, id: item.Id };
}));
}
});
EDIT:
Just checked jquery UI doc
You should use request.term thats it.
source: function(request, response) {
$.ajax({
url: "#Url.Action("GetDegree")",
type: "POST",
dataType: "json",
data: {
search: request.term
},
success: function(data) {
//....
}
});
}
I haven't had a lot of experience with jQuery but below is Autocomplete code that is successfully bolding the search characters in the search result dropdown rows:
.autocomplete({
delay: 500,
minLength: 0,
source: function(request, response) {
// delegate back to autocomplete, but extract the last term
var list = $.ui.autocomplete.filter(availableTags, extractLast(request.term));
if (request.term) {
regex = new RegExp('(' + extractLast(request.term) + ')', 'gi');
list = list.map(function(item) {
return {
label: item.label.replace(regex, '<b>$1</b>'),
value: item.value
}
})
}
response(list);
},
I'm now trying to switch the source to an AJAX lookup. Can anyone let me know what the edit would be to the following AJAX code to get bold text characters like the first code example does?
.autocomplete({
delay: 500,
minLength: 0,
source: function (request, response) {
$.ajax({
url: 'default.aspx/fGetCityLookupData',
data: "{'strSearchText': '" + extractLast(request.term) + "'}",
dataType: "json",
type: "POST",
contentType: "application/json; charset=utf-8",
success: function (data) {
response($.map(data.d, function (item) {
return {
label: item.split('|')[1],
value: item.split('|')[0]
}
}))
},
error: function (response) {
alert(response.responseText);
},
failure: function (response) {
alert(response.responseText);
}
});
},
TIA

I have this script that adds elements with data by a get json function.
$(document).ready(function() {
ADD.Listitem.get();
});
It basicly adds a bunch of html tags with data etc. The problem I have is following:
$(document).ready(function() {
ADD.Listitem.get();
var arr = [];
$(".Listitem-section-item-title").each(function() {
arr.push($(this.text()));
});
});
-
get: function(web) {
AST.Utils.JSON.get("/_vti_bin/AST/ListItem/ListitemService.svc/GetListItem", null, AST.Listitem.renderListitem);
},
renderListitem: function(data) {
$("#Listitem-template").tmpl(data["ListItemResults"]).prependTo(".ListItem-section-template");
}
and here is the json get:
ADD.Utils.JSON.get = function (url, data, onSuccess) {
$.ajax({
type: "GET",
contentType: "application/json; charset=utf-8",
async: true,
url: url,
data: data,
cache: false,
dataType: "json",
success: onSuccess,
error: ADD.Utils.JSON.error,
converters: { "text json": ADD.Utils.JSON.deserialize }
});
}
The array each loop is not running beacuse the get method is not finished with rendering the Listitem-section-item-title selector so it cant find the selector.
Is there any good solutions for this?
You could change your functions to return the promise given by $.ajax :
ADD.Utils.JSON.get = function (url, data) {
return $.ajax({
type: "GET",
contentType: "application/json; charset=utf-8",
async: true,
url: url,
data: data,
cache: false,
dataType: "json",
converters: { "text json": ADD.Utils.JSON.deserialize }
}).fail(ADD.Utils.JSON.error);
}
get: function(web) {
return AST.Utils.JSON.get("/_vti_bin/AST/ListItem/ListitemService.svc/GetListItem", null).done(AST.Listitem.renderListitem);
},
So that you can do
$(document).ready(function() {
ADD.Listitems.get().done(function(){
var arr = [];
$(".Listitem-section-item-title").each(function() {
arr.push($(this.text()));
});
});
});
Callback:
$(document).ready(function() {
ADD.Listitem.get(url,data,function(){
var arr = [];
$(".Listitem-section-item-title").each(function() {
arr.push($(this.text()));
});
});
});
Without callback:
If you cant get the get method to take a callback or return a promise then I think the best way will be to check when its done.
$(document).ready(function() {
ADD.Listitem.get();
var timer = setInterval(function(){
if ($("#thingWhichShouldExist").length>0){
var arr = [];
$(".Listitem-section-item-title").each(function() {
arr.push($(this.text()));
});
clearInterval(timer);
}
},50);
});
Retrieve the values and on success, call a function which will push the values into the array.
Also, arr.push($(this.text())); should be arr.push($(this).text());.
I am using Jquery autocomplete with ajax.
Everything works fine except when I set minLength to 0.
When I choose an element from the list, the autocomplete doesn't stop running and shows me the list again.
Here is the code:
$("#id_from").autocomplete({
source: function (request, response) {
$.ajax({
url: "http://127.0.0.1:8000/core/get_from_cities",
dataType: "json",
data: {term: request.term},
success: function (data) {
response($.map(data.data, function (item) {
return {
label: item.value,
value: item.value
}
}));
}
});
},
minLength: 0
});
Thanks..
EDIT:
Here is the solution I came up with:
$("#id_to").focus(function() {
$( "#id_to" ).autocomplete( "enable" );
});
$("#id_ffrom").autocomplete({
source: function (request, response) {
$.ajax({
url: "http://127.0.0.1:8000/core/get_from_cities",
dataType: "json",
data: {term: request.term},
success: function (data) {
response($.map(data.data, function (item) {
return {
label: item.city,
value: item.city,
}
}));
}
});
},
minLength: 0,
select: function (event, ui) {
$('#id_from_country').val(ui.item.country)
$("#id_ffrom").autocomplete( "disable" );
}
});
