i'm trying to add an autocomplete to an input box (i'm in asp.net/vb.net project) with the autocomplete source from a database.
So i've created a webservice and i did an ajax call:
<script type="text/javascript">
$(document).ready(function () {
$('#modelloInput').autocomplete({
source: function (request, response) {
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "WebServices/AutocompleteWS.asmx/getTuttiIModelli",
data: "{'prefix':'" + request.term + "'}",
dataType: "json",
async: true,
success: function (data) {
response(data.d);
},
error: function (result) {
//alert("Error");
}
});
}
});
});
</script>
<input type=text id="modelloInput" />
Now when i run the application and i write something in the inputbox i got the entire list in the autocomplete box.
I can write everything but i get always the entire list of elements.
Why?
I think there must be some issue in your web-service code,
you can use this basic code for autoComplete,
$( "input.suggest-user" ).autocomplete({
source: function( request, response ) {
$.ajax({
dataType: "json",
type : 'Get',
url: 'yourURL',
success: function(data) {
$('input.suggest-user').removeClass('ui-autocomplete-loading'); // hide loading image
response( $.map( data, function(item) {
// your operation on data
}));
},
error: function(data) {
$('input.suggest-user').removeClass('ui-autocomplete-loading');
}
});
},
minLength: 3,
open: function() {
},
close: function() {
},
focus:function(event,ui) {
},
select: function( event, ui ) {
}
});
OR
$("#id").autocomplete(
{
search: function () {},
source: function (request, response)
{
$.ajax(
{
url: ,
dataType: "json",
data:
{
term: request.term,
},
success: function (data)
{
response(data);
}
});
},
minLength: 2,
select: function (event, ui)
{
var test = ui.item ? ui.item.id : 0;
if (test > 0)
{}
}
});

After searching for an event successfully, I would like to open the update / delete dialog with all information filled in. But nothing happens.
I have this code in Default.aspx:
<script type="text/javascript">
$(function () {
$("[id$=txtSearch]").autocomplete({
source: function (request, response) {
$.ajax({
url: '<%=ResolveUrl("~/Default.aspx/GetEvent") %>',
data: "{ 'prefix': '" + request.term + "'}",
dataType: "json",
type: "POST",
contentType: "application/json; charset=utf-8",
success: function (data) {
response($.map(data.d, function (item) {
return {
label: item.split('|')[0],
val: item.split('|')[1]
}
}))
},
error: function (response) {
// alert(response.responseText);
},
failure: function (response) {
alert(response.responseText);
}
});
},
select: function (e, i) {
$("[id$=hfCustomerId]").val(i.item.val);
date = moment(i.item.label, "DD/MM/YYYY HH:mm");
$("#calendar").fullCalendar('gotoDate', date);
let eventProva = $("#calendar").fullCalendar("getEventById", i.item.label);
$("#calendar").fullCalendar('updateEvent', eventProva);
},
minLength: 1
});
});
</script>
where 'i.item.label' is the event id.But nothing happens with the line $("#calendar").fullCalendar('updateEvent', eventProva);
I need to dynamicly pass data to my select list with jquery. I see that data in console but my list is empty. Can you help me find the solution?
<script type="text/javascript">
var kunnr;
$(document).ready(function () {
$('#NAME1').autocomplete({
source: function (request, response) {
$.ajax({
url: "Form2",
method: 'POST',
data: {
term: $('#NAME1').val()
},
success: function (data) {
response(data);
}
});
},
select: function (event, ui) {
kunnr = ui.item.kunnr;
$.ajax({
url: "Form3",
method: 'POST',
data: {
kunnr: kunnr
},
success: function (data) {
console.log(data);
//there is my data ^ i need to pass to select list
}
});
}
});
});
</script>
My select list
#Html.DropDownListFor(model => model.Subaccount, new SelectList(" "), new { #class = "form-control" })
Change your javascript code to this
var kunnr;
$(document).ready(function () {
$('#NAME1').autocomplete({
source: function (request, response) {
$.ajax({
url: "Form2",
method: 'POST',
data: {
term: $('#NAME1').val()
},
success: function (data) {
response(data);
}
});
},
select: function (event, ui) {
kunnr = ui.item.kunnr;
$.ajax({
url: "Form3",
method: 'POST',
data: {
kunnr: kunnr
},
success: function (data) {
var selectData = JSON.parse(data);//use JSON.parse(), if the data is not already json formatted
$("#Subaccount").empty();
selectData.forEach(function (obj) {
//NOTE the Value and Text are what you assigned them when you fetched them
$('#Subaccount').append($('<option></option>').val(obj.Value).html(obj.Text));
});
}
});
}
});
});
I'm working with jQuery UI Auto Complete extenders for populating list.
Here i include this article for more reference of my code detail.
Here I modify method for auto complete. In article this calls from css class and I want from the ID of the control.
This is my jQuery script :
<script type="text/javascript">
$(document).ready(function () {
SearchText();
});
function SearchText() {
$("#<%=txt_reason.ClientID %>").autocomplete({
source: function (request, response) {
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "Raise_Ticket.aspx/SearchReasons",
data: "{'prefixText':'" + $("#<%=txt_reason.ClientID %>").val() + "'}",
dataType: "json",
success: function (data) {
response(data.d);
},
error: function (result) {
alert("Error");
}
});
}
});
}
</script>
And this is my method:
[System.Web.Script.Services.ScriptMethod(ResponseFormat = System.Web.Script.Services.ResponseFormat.Json)]
[System.Web.Services.WebMethod]
public static List<string> SearchReasons(string prefixText)
{
using (DataClassesDataContext db = new DataClassesDataContext())
{
var query = db.Reasons.Where(r => r.ReasonText.Contains(prefixText)).Select(r => r).ToList();
List<string> reasons = new List<string>();
foreach (var item in query)
{
reasons.Add(item.ReasonText.ToString());
}
return reasons;
}
}
The problem is not detecting this textbox not displaying result.
Use this
<script type="text/javascript">
$(document).ready(function () {
SearchText();
});
function SearchText() {
$("#txt_reason").autocomplete({
source: function (request, response) {
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "Raise_Ticket.aspx/SearchReasons",
data: "{'prefixText':'" + $("#txt_reason").val() + "'}",
dataType: "json",
success: function (data) {
response(data.d);
},
error: function (result) {
alert("Error");
}
});
}
});
}
</script>
Using this you can also try
$(document).ready(function () {
$("#textbox").autocomplete({
source: function (request, response) {
$.ajax({
url: "URL",
type: "POST",
dataType: "json",
data: { term: request.term },
success: function (retrieveddata) {
if (retrieveddata.length > 0) {
}
},
error: function (request, status, error) {
console.log("Error! " + request.responseText);
}
})
},
});
})
Take Tern Variable in Code
I am using jQuery Autocomplete.
It's making an AJAX request on every keypress which I don't want. If data from a previous AJAX request matches a search it should not make any more AJAX requests.
<script>
$('#tags').autocomplete({
source: function (request, response) {
$.ajax({
url: '/TestDDl/Index',
// data: "{ 'prefix': '" + request.term + "'}",
dataType: "json",
type: "POST",
contentType: "application/json; charset=utf-8",
success: function (data) {
response($.map(data.user, function (item) {
return {
label: data.name,
val: data.val
}
}))
},
error: function (response) {
alert(response.responseText);
},
failure: function (response) {
alert(response.responseText);
}
});
},
autoFocus: true,
keypress: function (event, ui) {
alert('Not Selected');
if (!ui.item) {
alert('Not Selected');
}
}
});
});
Here if I am typing the name of a user which is already in previous AJAX request data, it should not make an AJAX request on next the keypress.
You can declare a variable, assing user input to it, then update it in your success function. And just before making next call, check if your variable matches the next data.
Something like this:
<script>
var recent = '';
$('#tags').autocomplete({
source: function (request, response) {
if (recent == request.term) {
return;
}
recent = request.term;
$.ajax({
url: '/TestDDl/Index',
data: "{ 'prefix': '" + request.term + "'}",
dataType: "json",
type: "POST",
contentType: "application/json; charset=utf-8",
success: function (data) {
response($.map(data.user, function (item) {
return {
label: data.name,
val: data.val
}
}))
},
error: function (response) {
alert(response.responseText);
},
failure: function (response) {
alert(response.responseText);
}
});
},
autoFocus: true,
keypress: function (event, ui) {
alert('Not Selected');
if (!ui.item) {
alert('Not Selected');
}
}
});
</script>
<script>
window.xyz = []; //For saving history
$('#tags').autocomplete({
source: function (request, response) {
if(xyz[request]){
response(xyz[request]); // Return previously saved data
}else(
$.ajax({
url: '/TestDDl/Index',
// data: "{ 'prefix': '" + request.term + "'}",
dataType: "json",
type: "POST",
contentType: "application/json; charset=utf-8",
success: function (data) {
var res = $.map(data.user, function (item) {
return {
label: data.name,
val: data.val
}
});
xyz[request]=res; //set data to reuse later
response(res)
},
error: function (response) {
alert(response.responseText);
},
failure: function (response) {
alert(response.responseText);
}
});
}
},
autoFocus: true,
keypress: function (event, ui) {
alert('Not Selected');
if (!ui.item) {
alert('Not Selected');
}
}
});
</script>
Your next ajax reques should be in the Success function of the first ajax request.Buid the logic there.If you find the match don't call the second ajax request else call the second ajax request and all should be in the success function of the first ajax request.
I'm trying to recreate JQUery autocomplete example from its website:
http://jqueryui.com/autocomplete/#multiple-remote
The only thing I change is I changes the source property from :
source: function( request, response ) {
$.getJSON( "search.php", {
term: extractLast( request.term )
}, response );
},
To:
source: function (request, response) {
$.ajax({
type: "POST",
url: "/UIClientsWebService.asmx/SearchCRMUsers",
data: "{term:'" + extractLast(request.term) + "'}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (result) {
$("#commentBody").autocomplete("option", "source", result.d);
}
}, response);
},
Now the problem is autocomplete just work for first ',' . When I choose my first item, then when I want to search and choose second item, nothing happen. There is no error in my firebug. I can see search method call but source does not change and also nothing shown as my autocomplete items. I can see my search term change correctly but actually no search happen.
try add the option multiple: true to your script
$(document).ready(function() {
src = '/UIClientsWebService.asmx/SearchCRMUsers';
$("#yourSelector").autocomplete({
source: function(request, response) {
$.ajax({
url: src,
dataType: "json",
data: "{term:'" + extractLast(request.term) + "'}",
success: function(data) {
response(data);
}
});
},
min_length: 3,
delay: 300,
multipleSeparator:",",
multiple: true,
});
});
