What is causing “Uncaught SyntaxError: Unexpected token o” with $.parseJSON() and JSON.parse() [duplicate]

Answer 1

If the header is sent:

Content-Type: text/json

Then parseJSON() does not need to be called. For example:

In a PHP I would set the header like this:

 "someValue"));

And in Javascript I would have something like this for the success function:

success: function(response) {
// This will output "someValue" to the console.
// Note the lack of the parseJSON() call. parseJSON() is called for us because the header was sent as text/json
console.log(response.someKey);
}
