Ajax Response is not defeined - javascript

I am quite green when it comes to AJAX and am trying to get an email address from an ASP.Net code behind function
When using the below code I am getting the error as per the title of this issue.
This is the code I am using
$('.txtRequester').focusout(function () {
console.log("textBox has lost focus");
function ShowCurrentTime() {
$.ajax({
type: "POST",
url: "Default.aspx/FindEmailAddress",
data: '{id: "' + $("txtRequester").val + '" }',
contentType: "application/json; charset=utf-8",
dataType: "json",
success: OnSuccess,
failure: function (response) {
alert(response.d);
}
});
}
function OnSuccess(response) {
alert(response.d);
}
});
which is an adaptation of the code from this site.
ASP.Net Snippets
When changing the line
success: OnSuccess to success: alert(response) or success: alert(data)
I get the error up, but if I use success: alert("ok") I get the message saying ok so I suspect that I am getting into the function as below.
<System.Web.Services.WebMethod()> _
Public Shared Function FindEmailAddress(ByVal id As String) As String
Dim response As String = GetEmail(id)
Return response
End Function
I would be extremely grateful if someone to help me and let me know where I am going wrong on this one.
thanks

I think you have can check the state of failure by using this code below as I think there is wrong syntax used by you.
$('.txtRequester').focusout(function () {
console.log("textBox has lost focus");
function ShowCurrentTime() {
$.ajax({
type: "POST",
url: "Default.aspx/FindEmailAddress",
data: JSON.stringify({id: ' + $(".txtRequester").val() + ' }),
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(data, status, header){
console.log(data);
},
error: function (response) {
alert(response.d);
}
});
}
});
then definitely you will get error response, if your success won't hit.

You have not called the function thats why its never get called.
$('.txtRequester').focusout(function () {
console.log("textBox has lost focus");
ShowCurrentTime();
});
function ShowCurrentTime() {
$.ajax({
type: "POST",
url: "Default.aspx/FindEmailAddress",
data: '{id: "' + $("txtRequester").val() + '" }',
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (response) {
Onsuccess(response);
},
failure: function (response) {
alert(response.d);
}
});
}
function OnSuccess(response) {
alert(response.d);
}
This will help :)

use ajax directly ,
$('.txtRequester').focusout(function () {
console.log("textBox has lost focus");
var cond = $(".txtRequester").val();
$.ajax({
type: "POST",
url: "Default.aspx/FindEmailAddress",
data: {id:cond},
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(response){
alert(response.d);
},
failure: function (response) {
alert(response.d);
}
});
});

Change $('.txtRequester') to $('#txtRequester')
and
Change $("txtRequester").val to $('#txtRequester').val()

Post AJAX API Javascript SAPUI5 failed

I want to use POST method with AJAX in SAPUI5 javascript but I found an error.
var url = "https://xxxx*xxxx.co.id:8877/TaspenSAP/SimpanDosirPunah";
$.ajax({
type: "POST",
url: url,
data: JSON.stringify({
nomorDosir: "01001961288",
kodeCabang: "A02"
}),
dataType: "json",
async: false,
contentType: 'application/json; charset=utf-8',
success: function(data, textStatus, xhr){
console.log("sukses: " + data + " " + JSON.stringify(xhr));
},
error: function (e,xhr,textStatus,err,data) {
console.log(e);
console.log(xhr);
console.log(textStatus);
console.log(err);
}
});
error:
I already did change code with dataType=text, or data: {nomorDosir: "01001961288", kodeCabang: "A02"} (without stringify), but I not yet find the solution. How to fix this problem?
Thanks.

Not sure what your use case is but if you are trying to post to an oData service, it might be much easier to use SAPs createEntry method where the URL is the path to the model you want to post to and your JSON are the properties:
var oModel = new sap.ui.model.odata.v2.ODataModel("https://services.odata.org/V2/OData/OData.svc/");
//oModel should use your service uri
var url = "https://xxxx*xxxx.co.id:8877/TaspenSAP/SimpanDosirPunah";
oModel.createEntry(url, {
properties: {
nomorDosir: "01001961288",
kodeCabang: "A02"
}
}, {
method: "POST",
success: function(response) {
alert(JSON.stringify(response));
//do something
},
error: function(error) {
alert(JSON.stringify(error));
}
});
oModel.submitChanges();
What you have is wrong json format, you have:
data: JSON.stringify({nomorDosir: "01001961288", kodeCabang: "A02"}),
Which actually should be:
data: {"nomorDosir": "01001961288", "kodeCabang": "A02"},
Which then you don't need to do a json.stringify on, because it already IS a json format. Hope this will help you out.
Which you could also try is setting a variable outside like this:
var url = "https://xxxx*xxxx.co.id:8877/TaspenSAP/SimpanDosirPunah";
var json = {"nomorDosir": "01001961288", "kodeCabang": "A02"};
$.ajax({
type: "POST",
url: url,
data: json,
dataType: "json",
async: false,
contentType: 'application/json; charset=utf-8',
success: function(data, textStatus, xhr){
console.log("sukses: "+data+" "+JSON.stringify(xhr));
},
error: function (e,xhr,textStatus,err,data) {
console.log(e);
console.log(xhr);
console.log(textStatus);
console.log(err);
}
});

Why Unable to get success callback in Jquery/ajax call to RESTful services?

function GET() {
jQuery.support.cors = true;
$.ajax({
url: 'http://localhost:32253/api/UserDetail/GetRoleDetails',
type: 'GET',
async:true,
contentType: "application/json",

alert("Success!");
}
});
return false;
}
I am very much new to ajax,I tried a ajax call to my services method which returns value.But the success callback function is never fired .I only get error.What might be the reason?
I tried using dataType to jsonp and other similar solutions which had been found in Stackoverflow regarding this issue.Nothing worked out.I am getting server response as 200 oK.
try this code
$.ajax({
type: "POST",
url: URL,
async: true,
contentType: "application/json; charset=utf-8",
dataType: "json",
jsonp: "onJSONPLoad",
jsonpCallback: "newarticlescallback",
crossDomain: "false",
beforeSend: function (xhr) {
},
error: function (request, status, error) {
console.log("Error In Web Service...." + request.responseText);
return false;
},
success: ajax_success,
complete: function (xhr, status) {
}
});
create function "ajax_success" in ur page
like below
function ajax_success(parsedJSON) { //you code here
}
this may be help you
try this code
$.ajax({
type: "POST",
url: URL,
async: false,
contentType: "application/json; charset=utf-8",
dataType: "json",
jsonp: "onJSONPLoad",
jsonpCallback: "newarticlescallback",

},
success: function (data) {
Result = data;

Ajax method to a webmethod in asmx is not firing

I have a strange problem with the below AJAX jQuery method to call a webmethod in an asmx service. It's not firing when I try to call it, but the moment I uncomment any of the alert in code to debug, it works all of sudden.
It confuses me, what would be the problem? Am I missing something here..
Code:
var endXsession = function() {
var fwdURL = "";
$.ajax({
type: "POST",
url: "Session.asmx/RemoveSession",
data: "{}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(msge) {
//alert(msge.d);
fwdURL = msge.d;
},
error: function(response) {
//alert(response.responseText);
fwdURL = response.responseText;
}
});
//alert(fwdURL);
return fwdURL;
};
response.responseText is undefined ... it's response.statusText ..
function endXsession() {
var fwdURL = "";
$.ajax({
type: "POST",
url: "Session.asmx/RemoveSession",
data: "{}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (msge) {
// alert(msge.d);
fwdURL = msge.d;
}
,
error: function (response) {
// alert(response.statusText);
fwdURL = response.statusText;
}
});
// alert(fwdURL);
return fwdURL;
}
console.log(endXsession());

Call ajax.fail() from ajax.success()

So all I want to do is conditionally call the .fail method from within the .success method, how?
var ajaxCall = $.ajax({
url: pUrl,
type: "POST",
data: pData,
dataType: "json",
processData: false,
contentType: "application/json; charset=utf-8"
})
.always(function () {
alert("always");
})
.success(function (data) {
if (data == "fail") { ajaxCall.fail(); return; }
alert("success");
})
.fail(function () {
alert("fail");
});
$.ajax return a promise so you can't do it directly. Your best shot is that :
var fail = function () {
alert("fail");
};
var ajaxCall = $.ajax({
url: pUrl,
type: "POST",
data: pData,
dataType: "json",
processData: false,
contentType: "application/json; charset=utf-8"
})
.always(function () {
alert("always");
})
.success(function (data) {
if (data == "fail") { fail(); return; }
alert("success");
})
.fail(fail);
You can simply call as this.fail(); as shown below :-
var ajaxCall = $.ajax({
url: pUrl,
type: "POST",
data: pData,
dataType: "json",
processData: false,
contentType: "application/json; charset=utf-8"
})
.always(function () {
alert("always");
})
.success(function (data) {
if (data == "fail")
{
this.fail();
return;
}
alert("success");
})
.fail(function () {
alert("fail");
});
For more information :-
http://www.youlikeprogramming.com/2013/07/jqueryajax-conditionally-call-error-method-fro-success/
just use the "this" keyword to actually call any other method of the ajax call, I have made a sample for error method.
$.ajax({
url: 'url',
dataType: 'json',
contentType: 'application/json; charset=utf-8;',
type: 'GET',
success: function (dataReturn) {
this.error('error called explicitly');
},
error: function (errorMessage) {
if(errorMessage.ResponseText) // or directly compare as errorMessage !== "error called explicitly" if u send the same message elsewhere
//actual error code
else
alert(errorMessage);
}
});
hope this helps :)

function calling ajax returns false

I have a javascript function which makes a JSON call to a web service using jQuery.
In the success function I need to evaluate the JSON response and if necessary make another call to a different method in the same web service.
Here is how I do it:
function firstAjaxCall(aid, tid) {
$.ajax({
type: "POST",
contentType: "application/json;charset=utf-8",
url: "/webservices/Webservice.asmx/Method1",
data: "{ auctionId: '" + aid + "'}",
dataType: "json",
success: function (response) {
var respData = response.d;
//do some stuff
if (respData.HasEnded == true) {
clearInterval(tid);
var end = false;
end = endFunction(aid);
if (end) {
// do some other stuff
}
}
},
failure: function (errorMsg) { alert(errorMsg.toString()); }
});
}
and the endFunction which is being called from within the ajax success function:
function endFunction(aid) {
var hasEnded = false;
$.ajax({
type: "POST",
contentType: "application/json;charset=utf-8",
url: "/webservices/Webservice.asmx/Method2",
data: "{ auctionId: '" + aid + "'}",
dataType: "json",
success: function (callbackData) {
var endRespData = callbackData.d;
hasEnded = endRespData.Success;
alert(hasEnded.toString());
},
failure: function(XMLHttpRequest, textStatus, errorThrown) {
console.log(textStatus, errorThrown);
}
});
return hasEnded;
}
Here is the weird stuff. The ajax-call is made all right. The code on the server is running according to plan. However, if I try to set a firebug breakpoint in the success function of endFunction(aid) is is not hit, but the alert box is shown displaying the word true. This is somewhat good since it seems that we are actually reaching the success function. The hasEnded variable however is never set to true so it always returns false.
Calling endFunction(1) from the Firebug console displays an alert box with the word true and returns value false.
What's going wrong?
AJAX is asynchronous — the $.ajax call will not wait for the server to reply.
Therefore, the return hasEnded; line runs before the AJAX callback.
You need to make your endFunction take a callback parameter, like $.ajax does.
http://api.jquery.com/jQuery.ajax/
It looks like you're using "failure" in the documentation you have "error":
error(XMLHttpRequest, textStatus, errorThrown)
also you should do something like this:
function firstAjaxCall(aid, tid) {
$.ajax({
type: "POST",
contentType: "application/json;charset=utf-8",
url: "/webservices/Webservice.asmx/Method1",
data: "{ auctionId: '" + aid + "'}",
dataType: "json",
success: function (response) {
var respData = response.d;
//do some stuff
if (respData.HasEnded == true) {
clearInterval(tid);
var end = false;
endFunction(aid,function(endv){
if (endv) {
// do some other stuff
}
});
}
},
error: function (errorMsg) { alert(errorMsg.toString()); }
});
}
function endFunction(aid,endcallback) {
var hasEnded = false;
$.ajax({
type: "POST",
contentType: "application/json;charset=utf-8",
url: "/webservices/Webservice.asmx/Method2",
data: "{ auctionId: '" + aid + "'}",
dataType: "json",
success: function (callbackData) {
var endRespData = callbackData.d;
hasEnded = endRespData.Success;
alert(hasEnded.toString());
endcallback(hasEnded);
},
error: function(XMLHttpRequest, textStatus, errorThrown) {
console.log(textStatus, errorThrown);
endcallback("?");
}
});
//return hasEnded;
}
