<script src="../Script/jquery-1.10.2.js"></script>
<script src="../Script/jquery-ui.js"></script>
<script type="text/javascript">
$(function () {
$('.textBox').autocomplete({
source: function (request, response) {
$.ajax({
url: "/Services/BusService.asmx/GetRouteInfo",
data: { param: $('.textBox').val() },
dataType: "json",
type: "POST",
contentType: "application/json; charset=utf-8",
dataFilter: function (data) { return data; },
success: function (data) {

}
}))
},
error: function (XMLHttpRequest, textStatus, errorThrown) {

});
});
</script>
my c# code:
[WebMethod]
public string[] GetRouteInfo(string param)
{
List<string> list_result = new List<string>();
AutoTaxiEntities useEntity = new AutoTaxiEntities();
System.Data.Entity.Core.Objects.ObjectResult<DAL.Model.SP_FIND_ROUTE_ROUTESTOPS_Result> sp_result = useEntity.SP_FIND_ROUTE_ROUTESTOPS(param);
foreach (DAL.Model.SP_FIND_ROUTE_ROUTESTOPS_Result sp_result_item in sp_result.ToList())
{
list_result.Add(sp_result_item.ID + "," + sp_result_item.ITEMTYPE + "," + sp_result_item.TITLE);
}
return list_result.ToArray();
}
Looking at your added script references, i think you have not added autocomplete.js script. Please add it and try it once.Please click here
$(document).ready(function () {
$('#<%=txtSearch.ClientID%>').autocomplete({
source: function (request, response) {
$.ajax({
type: "POST",
url: "/Services/BusWebService.asmx/GetRouteInfo",
data: "{ 'param': '" + request.term + "' }",
dataType: "json",
contentType: "application/json; charset=utf-8",
dataFilter: function (data) { return data; },
success: function (data) {
response($.map(data.d, function (item) {
return {
itemid: item.split(',')[0],
itemtype: item.split(',')[1],
label: item.split(',')[2]
}
}))
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert(textStatus);
}
});
},
minLength: 2,
select: function (event, ui) {
$('#<%=hfItem.ClientID%>').val(ui.item.itemid + ',' + ui.item.itemtype + ',' + ui.item.label);
//$("form").submit();
}
});
});

If I use the lower version of jquery than many functionalities stops working. I searched for the solution but failed. Please help me with this issue. I am using a website template for my project.
Jquery
<script type="text/javascript">
var dollar = $.noConflict();
dollar(function () {
dollar("#txtDoctorLocation").autocomplete({
source: function (request, response) {
var param = { query: $('#txtDoctorLocation').val() };

i am Creating a page that search all client details...
i am also using json for autocomplete textbox with data of datatable...
<script type="text/javascript">
$(document).ready(function () {
$("#<%=txtSearch.ClientID %>").autocomplete({
source: function (request, response) {
$.ajax({
url: '<%=ResolveUrl("~/Service.asmx/GetCustomers") %>',
data: "{ 'prefix': '" + request.term + "'}",
dataType: "json",
type: "POST",
contentType: "application/json; charset=utf-8",
success: function (data) {
response($.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) {
$("#<%=hfCustomerId.ClientID %>").val(i.item.val);
},
minLength: 1
});
});
i want to view data of that selected name on textbox on textchanged event,
their setup of textbgox looks like..`
<asp:TextBox ID="txtSearch" runat="server" AutoPostBack="True"
ontextchanged="txtSearch_TextChanged"></asp:TextBox>
That textchenged event trigger properly in mozilla, but not working in chrome,,
can anyone suggests some solution....
I would suggest calling server side's textbox onchange event after selecting a value from the autocomplete list as,
...
select: function (e, i) {
$("#<%=hfCustomerId.ClientID %>").val(i.item.val);
__doPostBack("txtSearch", "TextChanged");
},
minLength: 1
});
and remove autopostback property of that textbox as we are firing it from client side.
Or you can make an ajax call on select event and populate required data in client side itself.
` $(document).ready(function () {
var prm = Sys.WebForms.PageRequestManager.getInstance();
prm.add_initializeRequest(InitializeRequest);
prm.add_endRequest(EndRequest);
InitAutoCompl();
});
function InitializeRequest(sender, args) {
}
function EndRequest(sender, args) {
InitAutoCompl();
}
function InitAutoCompl() {
$("#<%=txtSearch.ClientID %>").autocomplete({
source: function (request, response) {
$.ajax({
url: ''<%=ResolveUrl("~/Service.asmx/GetCustomers") %>',
data: "{ 'prefix': '" + request.term + "'}",
dataType: "json",
type: "POST",
contentType: "application/json; charset=utf-8",
success: function (data) {
response($.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);
}
});
},
minLength: 1, change: function (event, ui) { __doPostBack("txtSearch", "TextChanged"); }
});
}
and remove Autopostback="true" from TextBox

How do I create textbox which can save any input in database using jquery Ajax in Asp.net mvc4...
e.g:I write "my new task" in textbox and click on button and this saves in database with "The project" id and the "UserId" which is login in application,
so how can I create this in mvc4, here is my code..
public actionresult Insert(task,projectId,UserId)
{
//linq to sql here...
}
and Ajax code is
source: function(request, response) {
$.ajax({
url: pagePath + "/insert",
data: "{ 'id': '" + request.term + "'}",
dataType: "json",
type: "POST",
contentType: "application/json; charset=utf-8",
dataFilter: function(data) { return data; },
success: function(data) {
response($.map(data.d, function(item) {
{
value = item.Name
return value;
}
}))
},
error: function(XMLHttpRequest, callStatus, errorThrown) {
alert(callStatus);
}
});
},
Is this the correct way? Can someone please guide me
source: function(request, response) {
$.ajax({
url: "controllername/actionmethodname",
data: "{task:value,projectId:value,UserId:value }",
dataType: "json",
type: "POST",
success: function(data) {
response($.map(data.d, function(item) {
{
value = item.Name
return value;
}
}))
},
error: function(XMLHttpRequest, callStatus, errorThrown) {
alert(callStatus);
}
});
},
I am trying to use jQuery Autocomplete on a text box, but it's not working.
Here is my script to get autocomplete list from database but it gives me error and alerts error message.
$(function () {
$("#ContentPlaceHolderSearch_txt_Search").autocomplete({
source: function (request, response) {
$.ajax({
url: "Service/AutoComplete.asmx/GetCompletionListName",
data: "{ 'prefixText': '" + request.term + "' }",
dataType: "json",
type: "POST",
contentType: "application/json; charset=utf-8",
dataFilter: function (data) { return data; },
success: function (data) {
response($.map(data.d, function (item) {
return {
value: item
}
}))
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert(textStatus);
}
});
},
minLength: 2
});
});
Here Is my server code
[WebMethod]
public string[] GetCompletionListName(string prefixText, int count)
{
List<string> items = new List<string>(count);
GA_UsersTableAdapter uta = new GA_UsersTableAdapter();
UserControllar.GA_UsersDataTable udt = uta.GetDataByNameAutoComplete(prefixText);
foreach (DataRow row in udt.Rows)
{
items.Add(row["Full_Name"].ToString());
}
return items.ToArray();
}
i just changed my service path in script from
url: "Service/AutoComplete.asmx/GetCompletionListName"
to
url: "../Service/AutoComplete.asmx/GetCompletionListName"
and it works now...
I now have a working JavaScript autocomplete function, thanks to help from many of you. Now I want to make the function reusable. There are three variables that need to be specified for each instance of the function, as shown below. What I don't know how to do is instantiate this function with different values for these three vars.
Here is my HTML field:
<div class="ui-widget">
Text or Value:
<input type="text" id="dotmatch" />
</div>
And here is the JavaScript code which I want to keep in its own .js file:
var matchFieldName = 'dotmatch';
var resultFieldName = 'dotnumber';
var lookupURL = "/AutoSuggestJSTest/AutoSuggest.asmx/DOTList";
$(function() {
$('#' + matchFieldName).autocomplete({
source: function(request, response) {
$.ajax({
type: "POST",
url: lookupURL,
contentType: 'application/json',
dataType: "json",
data: JSON.stringify({ prefixText: request.term, count: 20 }),
success: function(data) {
var output = jQuery.parseJSON(data.d);
response($.map(output, function(item) {
return {
label: item.Label + "(" + item.Value+ ")",
value: item.Value
}
}));
},
error: function(XMLHttpRequest, textStatus, errorThrown) {
alert(textStatus);
}
});
},
minLength: 2,
select: function(event, ui) {
$('#' + resultFieldName).val(ui.item.value);
return ui.item.label;
}
});
});
insin was close. The solution I worked out this morning is;
function AutoComplete(matchFieldName, resultFieldName, lookupURL) {
$('#' + matchFieldName).autocomplete({
source: function(request, response) {
$.ajax({
type: "POST",
url: lookupURL,
contentType: 'application/json',
dataType: "json",
data: JSON.stringify({ prefixText: request.term, count: 20 }),
success: function(data) {
var output = jQuery.parseJSON(data.d);
response($.map(output, function(item) {
return {
value: item.Value,
label: (item.Label == item.Value) ? item.Label : item.Label + "(" + item.Value + ")"
}
}));
},
error: function(XMLHttpRequest, textStatus, errorThrown) {
alert(textStatus);
}
});
},
minLength: 2,
select: function(event, ui) {
$('#' + resultFieldName).val(ui.item.value);
}
});
}
On the web page:
<div id="AutoSuggest">
DOT Job Title or Number:
<input type="text" id="dotmatch" style="width:300px;" />
</div>
And on the web page, after the tag:
<script type="text/javascript" src="js/DOTAutocomplete.js"></script>
<script type="text/javascript">
$(function() {
AutoComplete("dotmatch", "dotnumber", "/AutoSuggestJSTest/AutoSuggest.asmx/DOTList");
});
</script>
It looks like you're using jQuery, so you might want to implement it as a plugin.
(function($) {
$.fn.bobsAutocomplete = function(resultFieldName, lookupURL) {
this.autocomplete({
source: function(request, response) {
$.ajax({
type: "POST",
url: lookupURL,
contentType: 'application/json',
dataType: "json",
data: JSON.stringify({prefixText: request.term, count: 20}),
success: function(data) {
var output = jQuery.parseJSON(data.d);
response($.map(output, function(item) {
return {
label: item.Label + "(" + item.Value+ ")",
value: item.Value
}
}));
},
error: function(XMLHttpRequest, textStatus, errorThrown) {
alert(textStatus);
}
});
},
minLength: 2,
select: function(event, ui) {
$('#' + resultFieldName).val(ui.item.value);
return ui.item.label;
}
});
return this;
};
})(jQuery);
Usage:
$("#dotmatch").bobsAutocomplete("dotnumber", "/AutoSuggestJSTest/AutoSuggest.asmx/DOTList");
