jQuery getJSON成功时从不调用成功函数

Question

I am using jQuery to retrieve json data from a server. The server responds with a json-encoded object. The problem is, after the server responds, my success function does not get called.

Here is my request:

$('form').on('submit', function(event) {
  event.preventDefault();
  $.getJSON('?getAvailableRoom', function(data, textStatus, jqXHR) {
    alert("Success!"); // doesn't happen
  });
});

Here is the response from the server:

Answer 1

Your JSON is invalid.

It should be:

Response
{"id":"AsuRC"}
