[jQuery] Sending a JSON object as data in an AJAX request

[jlb]

According to the jQuery docs, the data option (in $.ajax) is supposed
to accept a string or an object (which it then converts to a query
string).  It appears as though its not converting my object:


My Javascript is:

        var json = {
          "Request" : {
              "action"     : "doSomething",
              "params"   : {"id":"123"}
          }
       };

        $.ajax({
            type: "POST",
            url: WEB_DOMAIN + "/api.php",
            data: json
        });

In api.php contains:

 <?php var_dump($_REQUEST['Request']); ?>

Which outputs:

string(15) "[object Object]"


Does anyone know what I'm doing wrong?
