Ajax - Firefox not working

ajax chrome also works. But firefox is not working. I did not understand the reason. Sometimes I have this problem. Firefox also needs to be written differently. Help please.
$(function () {
//[id$ = txtAra]
$("[id$=txtAra]").autocomplete({
source: function (request, response) {
$.ajax({
url: "/AramaScript.aspx/Search",
data: "{ 'prefix': '" + request.term + "'}",
dataType: "json",
type: "POST",
contentType: "application/json; charset=utf-8",
success: function (data) {
response($.map(data.d, function (item) {
return {
label: item,
val: item
}
}))
},
error: function (response) {
alert(response.responseText);
},
failure: function (response) {
alert(response.responseText);
}
});
},
select: function (e, i) {
$("#btnAra").click();
},
minLength: 1
});
});

Autocomplete adding extra spaces

Image Example
Image Example Keyboard
My auto commplete is adding extra spaces when data is selected from web services, how do i fix this?
i've tried mostly everything but isnt getting any results
Code:
https://jsfiddle.net/jz1e4tr6/1/
$(document).ready(function () {
$("#<%=TextBox1.ClientID%>").autocomplete({
source: function (request, response) {
$.ajax({
url: '<%=ResolveUrl("/Normal/WebServices/AutoComplete.asmx/GetSubject")%>',
data: "{ 'prefix': '" + request.term + "'}",
dataType: "json",
type: "POST",
contentType: "application/json; charset=utf-8",
success: function (data) {
response($.map(data.d, function (item) {
return {
label: item.split('-')[0],
attr: item.split('-')[1]
}
}))
},
error: function (response) {
alert(response.responseText);
},
failure: function (response) {
alert(response.responseText);
}
});
},

An alternative "tweak" but not the right solution... before clicking submit in the code behind... i get the value from the textbox and into a variable. And trim the variable.

Textbox's Textchanged event not fire in chrome

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);

Autocomplete returns an error on ajax request

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...
