$.postJSON about jquery-json HOT 3 CLOSED

From coolaj86 on January 21, 2010 12:48:47

There's a jquery.cors plugin which I'm working on which also relies on jquery.json
and I have that method in there.

If you'd like to help, let me know.

I'm not sure what the purpose of this function is intended to be.

jQuery has $.getJSON, which takes (url, data, success) and it makes a GET request to 'url' with data (which is an object, translated to a querystring like foo=bar&lorem=ipsum) and it parses the return value of the server (not the sending value of the client) as JSON and passes the parsed object into the success callback function.

A function named postJSON, in my opinion, would make a similar request but as POST, parsing the server return as JSON, not sending JSON to the server.

This seems a bit out of the scope of this plugin in my opinion. You could request the following to be added to jQuery though, in which case you can send JSON to the server in POST like this:

  // in jQuery core
  $.postJSON = function( url, data, callback ) {
    return jQuery.get( url, data, callback, "json" );
  }

  // In your application
  $.postJSON( 'awesome.php', { data: $.toJSON( ... ), function( response ) { ... } );

Status: WontFix

From the reference implementation ( http://json.org/JSONRequest.html ):
"JSONRequest.post does an HTTP POST of a the serialization of a JavaScript object or array, gets the response, and parses the response into a JavaScript value. If the parse is successful, it returns the value to the requesting script. In making the request, no HTTP authentication or cookies are sent. Any cookies returned by the server cause the request to fail. The JSONRequest service can only be used to send and receive JSON-encoded values. JSONRequest cannot be used to retrieve other text formats."

From there, the proposed $.postJSON() function looks consistent to me, but it depends on a 3rd party library like jquery-json (or json2.js) to do the json encoding.
