$.getJSON doesn't work but $.get does?

Question

PHP

Help solve the problem.
doing so

$.getJSON('http://somedomain.com/mmm?callback=? ')
  .done(function(data) {
    console.log(data);
  })
  .fail(function(jqXHR, status, error) {
    console.log(status, error);
  });

if I change getJSON to get, then in console.log() in the .done() function, the normal data object immediately falls out, which is what is needed. But why doesn't getJSON work? gives an error message

parsererror SyntaxError {stack: (...), message: "Unexpected token :"}

here are the response headers

Answer 1

You need to understand the difference between jsonp and json. These are fundamentally different things. Jsonp is how your script will wrap and play. It needs a callback. With jsonp, a script dom element is created in the body of the document into which the response is inserted. Naturally, this element must contain valid js code, with a function. Those. the server should return something like function qwe(){ /* code here */ }. And json is, in fact, a serialized array in some way, which by itself will not be executed in any way.

Answer 2

yes, the answer is probably not quite valid for json parser

Answer 3

And look what comes to jqXHR.responseText.
Maybe there's some bullshit in there.
