This question has already been answered:

Hello. There is such a JS code:

$(document).ready(function() { $.getJSON('https://...?callback=?', function(data) { //ответ от сервера успешно получаю alert("Im in JSON"); }); alert("Im out JSON"); });

Question: why as a result is the “Im out JSON” alert first executed, and only then “Im in JSON”? Why is this kind of logic "the other way around"?

$.getJSON an asynchronous event, that is, it is executed after receiving a response from the server and does not block the execution of the rest of the code.

    This is due to asynchrony. To disable it, you can add this:

     jQuery.ajaxSetup({async:false});

    UPD: But better not.
