How can I store the data in a variable of an ajax call and print it?

I have two files one with a login form, and one with the response content if the call is successful, it executes another one for loading buttons. What I would like to do is that inside the first call there is a field called RSociale and that inside has the name and surname of the user who logged in. How can I retrieve that field and print it in the part where the buttons are already there?
This is the ajax call to login:
function lg_controllacredenziali() {
sem_PulisciCampiObbligatori();
if ($('#password').hasClass("form-required") == false) { $('#password').addClass("form-required"); }
if ($('#password').hasClass("form-text") == false) { $('#password').addClass("form-text"); }
if ($('#user').val() == '') {
sem_ControllaCampiRichiesti();
lg_ControllaCampiText();
}
if ($('#user').hasClass("input-text") == true) { $('#user').removeClass("input-text"); }
if ($('#user').hasClass("input-user") == true) { $('#user').removeClass("input-user"); }
if ($('#password').hasClass("input-text") == true) { $('#password').removeClass("input-text"); }
if ($('#password').val() == '') {
sem_ControllaCampiRichiesti();
lg_ControllaCampiText();
} else {
jQuery.ajax({
url: sem_wsurl + 'ws_json_intra_logon',
type: 'GET',
data: {
login: $('#user').val(),
clear: 'S',
password: encodeURI($('#password').val())
},
dataType: 'jsonp',
processData: true,
success: function(json) {
if (json.Response[0].ResultCode != "000") {
lg_ControllaCampifalse();
if ($('#password').hasClass("input-false") == false) { $('#password').addClass("input-false"); }
if ($('#user').hasClass("input-false") == false) { $('#user').addClass("input-false"); }
if ($('#user').hasClass("input-required") == false) { $('#user').addClass("input-required"); }
if ($('#password').hasClass("input-required") == false) { $('#password').addClass("input-required"); }
} else {
//Setto i Cookie
sem_setCookie("wc_login",$('#user').val(),null);
sem_setCookie("wc_password",json.Response[0].Pwdcookie,null);
//lg_setCookie("wc_database",json.Response[0].Dbcookie,10);
sem_setCookie("wc_database","dbeutelia",null);
sem_setCookie("wc_header",sem_header,null);
sem_setCookie("wc_footer",sem_footer,null);
window.location.replace("sem_menu.html");
window.open(url, "_self");
}
},
error: function(error) {}
});
}
}
If the call is successful, it opens a page which in its turn makes another call to load the buttons
function CaricaCluster() {
if (sem_readCookie("wc_login") != null && sem_readCookie("wc_password") != null)
{
if (sem_readCookie("wc_login").replace(/\"/g,"") != '' && sem_readCookie("wc_password").replace(/\"/g,"") != '') {
jQuery.ajax({
url: sem_wsurl + 'ws_json_sem_cluster',
type: 'GET',
data: {
ws_login: sem_readCookie("wc_login").replace(/\"/g,""),
ws_password_type: 'C',
ws_pwd: encodeURI(sem_readCookie("wc_password").replace(/\"/g,""))
},
dataType: 'jsonp',
processData: true,
success: function(json) {
if (json.Response[0].ResultCode != "000") alert("errore");
else {
$.each(json, function() {
TblPulsanti = json.Response[0].Details;
StampaPulsanti();
});
}
},
error: function(error) {
alert("Errore");
}
});
}
}
}

Select2 - load data once from remote but perform search on client

I am trying to use "query" object to perform what i want. Everythings works except when i select an option nothing happen (placeholder is not replaced).
I have followed the instructing from this post Loading remote data only once with Select2
init() {
this.$view.select2({
theme: "bootstrap",
language: "fr",
allowClear: this.options.allowClear,
placeholder: this.options.placeholder,
query: (query) => {
if (this.items) {
query.callback({results: this.filterItems(query.term)});
} else {
this.loadData(query);
}
},
templateResult: (state) => {
return this.format(state);
}
});
}
loadData(query) {
$.ajax({
url: this.options.url,
dataType: 'json',
type: 'GET',
success: (data) => {
this.items = [];
for (let row of data) {
this.items.push({
id: row.id,
entity_id: row.entity_id,
text: row.label,
type: row.type,
disabled: !row.enable
});
}
query.callback({results: this.items});
}
});
}
filterItems(term) {
if (typeof term == "undefined" || term === null) {
return this.items;
}
const _term = $.trim(term.toLowerCase());
if (_term === '') {
return this.items;
}
return this.items.filter((item) => {
return item.text.toLowerCase().includes(term);
});
}
Thanx for help,

I think i have found a solution :
var s2data = $view.select2({
ajax: {
url: 'https://api.github.com/search/repositories',
data: {
q: 'select2'
},
dataType: 'json',
processResults: function(data) {
var items = [];
for (var row of data.items) {
items.push({
id: row.id,
text: row.name
});
}
this.options.set('cacheDataSource', {items: items});
return {
results: items
};
}
},
cacheDataSource: [],
allowClear: true,
placeholder: 'Select Values ...',
width: '100%',
}).data('select2');
s2data.dataAdapter.query = function(params, callback) {
var cacheDataSource = this.options.get('cacheDataSource');
if (cacheDataSource && cacheDataSource.items) {
var term = params.term;
if (typeof term == "undefined" || term == null) {
callback({results: cacheDataSource.items});
return
}
term = $.trim(term.toLowerCase());
if (term == "") {
callback({results: cacheDataSource.items});
return
}
callback({ results: cacheDataSource.items.filter(function(item) {
return item.text.toLowerCase().includes(term);
})
});
} else {
// call the original logic
var ajaxAdapterFunc = jQuery.fn.select2.amd.require('select2/data/ajax');
var ajaxAdapter = new ajaxAdapterFunc(this.$element, this.options);
ajaxAdapter.query(params, callback);
}
}

I noticed that your function code is tabbed once more than your code that calls it. It's possible that your function is scoped improperly (e.g. it's declared inside another function and you're calling it from outside that function).
If your function is coming back as undefined, it's almost certainly a scoping issue. I see nothing wrong with the function itself.
For instance:
$(document).ready(function () {
function myFunction() {
return 3;
}
});
var bob = myFunction(); //Error: myFunction is not defined.
