Jquery, Synchronous $.getJSON?

Question

JavaScript

Good afternoon.
Can you please tell me if it is possible to execute the $.getJSON function synchronously?
$.ajaxSetup({ async: false }); Does not help

Answer 1

$.ajax({
  url: url,
  dataType: 'json',
  async: false,
  data: data,
  success: callback
});

Answer 2

Somehow too lazy to think, but I think this will work:
var json = (function(data_url){
var result;
$.ajax({
async: false,
url: data_url,
dataType: 'json',
success: function®{
result = r;
}
});
return result;
})(url);

Answer 3

From the documentation for jQuery they write that it is not.
"
async
Default: true
… Cross-domain requests and dataType: "jsonp" requests do not support synchronous operation. Note that synchronous requests may temporarily lock the browser, disabling any actions while the request is active.
