how to catch the jquery ajax function return value in another variable

I am looking to store a value which is return by the AJAX function, here is the my code, in the AJAX success it is showing well, but when am storing that data which is saying undefined.
The following serviceNumber, which I am storing the enCrypt return value
var serviceNumber = enCrypt(typeofServiceNumber);// when am catching the function data which is saying "undefined"
the following code is my ajax function
function enCrypt(id) {
if (id > 0) {
$.ajax({
url: $("baseUrl").html() + "JobProfiles/Encryption",
type: "POST",
dataType: "json",
data: { Id: id },
success: function (encdata) {
return encdata;
},
error: function (data) {
$('#loading').hide();
}
});
}
}
Can you help me to know what is wrong in my code? Thanks in advance.

You can't use return like this, because the function is async + it's a function in a function...so actually yeah you cant return there xD
Just do something like:
enCrypt(typeofServiceNumber);
//and in your ajax:
success: function (encdata) {
go_on(encdata);
},
//and then
function go_on(serviceNumber)
{
//here you can use it :D
}

just add the
cache: false,
async: false,
to you ajax function
function enCrypt(id) {
var encnum;
$.ajax({
url: $("baseUrl").html() + "JobProfiles/EncodeIds",
type: "POST",
cache: false,
async: false,
dataType: "Json",
data: { Ids: id },
success: function (encdata) {
encnum = encdata;
},
error: function (data) {
$('#loading').hide();
}
});
return encnum;
}

How to set the some specified time to ajax call ,So that if request is taking time retrieve the data ,It should come to the FAIL Block

var ajaxRequest = new enyo.Ajax({
cacheBust: false,
contentType: 'application/json;charset=utf-8',
method: 'POST',
timeout: 8000,
async: false,
handleAs: 'json',
data: JSON.stringify({
// Data to connect to the external service.
url: url
method: 'GET',
contenttype: 'application/json;charset=utf-8',
content: 'username=l&pwd=p' + searchParams
}),
success: function (inSender, inResponse) {
},
fail: function (inSender, inResponse) {
}
ajaxRequest.go(ajaxRequest.data).response('success').error('fail');
};
lets say ,call to the webservice taking 5 to 6 seconds time or if there is slow internet connection ,How to redirect to fail block

what about manually call to fail-callback-func, something like:
var getDataFail = true;
function getData() {
setTimeOut(fileCallbackFunc, 6000);
$.ajax({
url: yourURL,
success: doneCallbck,
error: doneCallbck,
//other ajax params
});
}
function fileCallbck() {
if (getDataFail) {
//your fail logic...
console.error('get data fail');
}
}
function doneCallbck() {
getDataFail = false;
console.error('get data done');
}

ajax request not working on IE

function VReload()
{
$.ajax({
type: "GET",
url: "/foo/",
success: function (data) {
$("#myid").html(data);
}
});
}
$(document).ready(function() {
setInterval('VReload()', 1000)
});
This piece of code is working fine on Mozilla and chrome but not on IE. Ajax call is not firing on IE. What could be the reason.

Switch off caching by doing this:
$.ajax({
type: "GET",
cache: false,
url: "/foo/",
success: function (data) {
$("#myid").html(data);
}
});

set cache false
$.ajaxSetup({ cache: false });
or
$.ajax({
cache: false,
//other options
});

Try this:
function VReload()
{
var timestamp = new Date();
$.ajax({
type: "GET",
url: "/foo/" + "&timestamp=" + timestamp.getTime(),
success: function (data) {
$("#myid").html(data);
}
});
}
$(document).ready(function() {
setInterval('VReload()', 1000)
});

use jQuery's $.get() function
$.get('/foo/', {}, function(data){
// whatever
});

jQuery Ajax Function

I am trying to write a jQuery Ajax function, to reduce the amount of code in the page because the script is called a few times in the page. I can't seem to get it to work. Here is the code i have:
var loadURL = $(this).attr('href');
function load(){
$.ajax({
url: loadURL,
type: 'GET',
cache: true,
data: {
delay: 4
},
success: function(data) {
$('#load').html(data)
}
});
return false;}
$('#one').click(function(){ load(); });
$('#two').click(function(){ load(); });
$('#three').click(function(){ load(); });
Two
Two
Two
can anyone guide me here please?

i think the way you are getting href is wrong
function load(item){
var loadURL = $(item).attr('href');
$.ajax({
url: loadURL,
type: 'GET',
cache: true,
data: {
delay: 4
},
success: function(data) {
$('#load').html(data)
}
});
return false;}
$('#one').click(function()
{
load($(this));
return false; //you should mention return false here
});

It is worth noting that you can define your own jQuery functions if you wish..

jquery exit function in ajax call

Is there a way to exit a function, depending on the result of an GET request.
For example, in the below function, hi, if the GET results in data, where data === '1', I want to exit the function.
function hi () {
$.ajax({
url: "/shop/haveItem",
type: "GET",
success: function (data) {
if (data == '1') {
// exit hi() function
}
}
});
// some executable code when data is not '1'
}
How can I go about accomplishing this?

I think the solution can be something like this
function hi () {
$.ajax({
url: "/shop/haveItem",
type: "GET",
success: function (data) {
if (data == '1') {
ifData1();
} else {
ifDataNot1()
}
}
});
}
function ifData1 () { /* etc */ }
function ifDataNot1 () { /* etc */ }
If you have an ajax function, you should always work with callback functions. If you make an ajax function synchronous, then the browser will be blocked for the duration of ajax call. Which means that the application will remain non-responsive during the duration of the call.

You should be able to return false to simulate "exit".
function hi()
{
$.ajax({
url: "/shop/haveItem",
type: "GET",
async:false,
success: function(data){
if(data == '1')
return false
}
});
//some executable code when data is not '1'
...
}

One thing you can do is have a flag variable. Assign it to true or false, depending on if you want to exit or not.
function hi()
{
var flag=false;
$.ajax({
url: "/shop/haveItem",
type: "GET",
async:false,
success: function(data){
if(data == '1')
flag=true;
}
});
if ( flag ) return;
//some executable code when data is not '1'
...
}

Creating a global flag variable I think would work the best. Tested and working!!
window.flag = [];
function hi()
{
$.ajax({
url: "/shop/haveItem",
type: "GET",
async:false,
success: function(data){
if(data == '1')
flag = true;
}
});
if (flag) {
return false;
}
//some executable code when data is not '1'
...
}
