Get ajax request result as input for second ajax request

I am a bit stuck with the below issue, my code is similar to this:
function (){
var myVar = myFirstAjaxFunction()
$.ajax({
url: myUrl + myVar
....
})
}
My first ajax function is returning a string that I would like to use in the end of my function, but I do not know how to wait for the first function to be done.
I hope this is clear, thanks for your help!

Here is an example:
$.ajax({
success: function (data) {
var a = data;
$.ajax({
data: 'data=' + a,
success: function (data2) {
}
});
}
});
Or you pass callback :
function myFirstAjaxFunction (callback){
$.ajax({
success: function (data) {
callback(data);
}
});
}
and usage :
myFirstAjaxFunction(function(data){
//call 2nd ajax
});

$.post(url1,{ params:myVar}, function(result) {
$.post(url2,{params:result}, function(final_result) {
//use final_result here... :)
});
});

I think you should take help of callback function, please look at the below code. will help you.
function myFirstAjaxFunction(callback){
$.ajax({
url: "demo_test.txt",
success: function(result){
return callback('your-string');
}
});
}
function (){
myFirstAjaxFunction(function(myVar){
$.ajax({
url: myUrl + myVar
....
})
})
}

Return the promise from the ajax call. Example snippet for your reference
function (){
myFirstAjaxFunction()
}
function myFirstAjaxFunction() {
$.ajax({
url: '',
success: function(response) {
//response of the first api call
secondApiCall(responseoffirst);
}
});
}
function secondApiCall(value) {
$.ajax({
url: '',
success: function(response) {
console.log(response);
}
});
}

You can use Async/Await:
async function (){
var myVar = await $.ajax({
url: firstAjaxCallUrl
....
})
$.ajax({
url: myUrl + myVar
....
})
}

Ajax is not a function

I'm getting this problem with my jQuery when I type something on my input type.
There is my js:
$(document).ready(function(){
$("#cif").keyup(function(){
var name = document.getElementById("cif").value;
console.info(name);
$.ajax({
type: 'post',
url: '<?php echo site_url(); ?>register/cif',
dataType: 'json',
data: {
cif:name,
},
success: function (response) {
$('#raosocial').html(response);
if(response=="OK"){
return true;
}
else{
return false;
}
}
});
});
});
I tried without $.ajax but syntax error appeared

Make sure you aren't using the slim version of jQuery that doesn't include $.ajax().Download the full jQuery here

SyntaxError: expected expression, got '}'

I'm starting to program with JS and PHP and my question is why the console give this error, I search a lot of websites but without clues about this. If you can help I'll apreciate it
<script>
$(function(){
$("#btn_enviar").click(function(){
$.ajax({
type: "post",
url: "registro.php",
data: $("#form_members").serialize(),
success: function()
});
});
return false;
});
</script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>

you forgot {} after function()
Updated JS
$(function () {
$("#btn_enviar").click(function () {
$.ajax({
type: "post",
url: "registro.php",
data: $("#form_members").serialize(),
success: function (){}
});
});
return false;
});

how to use ajax response data in another javascript

I am working with google map.My map data come from php using ajax response.
My ajax code:
<script type="text/javascript">
$.ajax({
type: "POST",
url: "mapajax.php",
dataType:'text',
success: function (result) {
console.log(result);
}
});
</script>
Now I have need to put my response data in my map var location
function initialize() {
var locations = [
//Now here I put my ajax response result
];
How can I do that?

You'll have to refactor your code a little. I'm assuming you call initialize from the success callback.
Pass the locations array as an argument to initialize.
function initialize(locations) { ... }
$.ajax({
type: "POST",
url: "mapajax.php",
dataType:'text',
success: function (result) {
initialize(result);
}
});
Then you can cut down even more and just do success: initialize, as long as initialize doesn't expect other parameters.

Here is a fiddle with an example using $.when but its for SYNTAX only not making the call
http://jsfiddle.net/2y6689mu/
// Returns a deferred object
function mapData(){ return $.ajax({
type: "POST",
url: "mapajax.php",
dataType:'text'
});
}
// This is the magic where it waits for the data to be resolved
$.when( mapData() ).then( initialize, errorHandler );
EDIT** function already returns a promise so you can just use
mapData().then()
per code-jaff comments

This is done using callbacks, http://recurial.com/programming/understanding-callback-functions-in-javascript/ , here's a link if you want to read up on those. Let's see your current code here:
<script type="text/javascript">
$.ajax({
type: "POST",
url: "mapajax.php",
dataType:'text',
success: function (result) {
console.log(result);
}
});
</script>
As you noticed, the 'result' data is accessible in the success function. So how do you get transport it to another function? You used console.log(result) to print the data to your console. And without realizing it, you almost solved the problem yourself.
Just call the initialize function inside the success function of the ajax call:
<script type="text/javascript">
$.ajax({
type: "POST",
url: "mapajax.php",
dataType:'text',
success: function (result) {
initialize(result);
}
});
</script>

Is expected dataType response from $.ajax() to mapajax.php call text ?
Try
$(function () {
function initialize(data) {
var locations = [
//Now here I put my ajax response result
];
// "put my ajax response result"
// utilizing `Array.prototype.push()`
locations.push(data);
// do stuff
// with `locations` data, e.g.,
return console.log(JSON.parse(locations));
};
$.ajax({
type: "POST",
url: "mapajax.php",
dataType: 'text',
success: function (result) {
initialize(result);
}
});
});

jquery function problem

I have this function
function onclickRowRecord(recordID) {
$.ajax({
type: "POST",
url: '/file/to/post.to.php' ,
data: {recordID:recordID},
success: function(data) {
//how to post this to function howToPost(recordID) the recordID
}
});
}
function howToPost(recordID){
alert(recordID);
}
so how can I get the response from ajax success and post to the other function

If post you mean call the hotToPost function, then
...
success: function(data) {
howToPost(data.recordID); //or whatever
}
....
Hope this helps.

$.ajax({
type: "POST", url: '/file/to/post.to.php' , data: {recordID:recordID}, success: function(data) {
alert(recordID)
}
});
Does that work? Kinda new to jQuery
