We shouldn’t forget to validate our JSON data! There’s an online JSON Validator tool called JSONLint that can be used to validate JSON files. This is the best and most reliable option. The data is supplied in the form of an object, which leaves the task of creating the query string (or transmitting the request body) up to jQuery.

The exact status code is API-dependent, but for most GET requests, a status code of 200 is usual. Here we check the status to ensure that the result is indeed the object returned from a successful request and not some object containing an error message. In this case, a potential success callback would look like this: function success ( data ) ) In the simplest scenario, we only care about the returned object.

the optional success(data, textStatus, jqXHR) parameter, which is a callback function executed only if the request succeeds.

the optional data parameter, which is either an object or a string that’s sent to the server with the request.

the url parameter, which is a string containing the URL to which the request is sent.

One represents the data to send to the server the other one represents a callback to trigger in case of a successful response. getJSON (url, data, success ) īesides the required URL parameter, we can pass in two optional parameters. Essentially, it boils down to the more general $.ajax() helper, with the right options being used implicitly. The $.getJSON() method is a handy helper for working with JSON directly if you don’t require much extra configuration.
