Say I submit a form via Ajax and need a response from the server:

• Pass/fail indicator
• On fail, a list of validation errors with associated field ids/names, etc

Is there a standard or best practice for the JSON format for such a structure? If so, I'd like to try to stick to it instead of ing up with my own convention.

OmniTI has a decent standard that I like and remend: http://labs.omniti./labs/jsend

{
    status : "success",
    data : {
        "posts" : [
            { "id" : 1, "title" : "A blog post", "body" : "Some useful content" },
            { "id" : 2, "title" : "Another blog post", "body" : "More content" },
        ]
     }
}

I usually use a variant:

{
    status : "error",
    messages : {
        "some_field" : "message"
    }
}

Peter Bui's got this proposal format: http://paydrotalks./posts/45-standard-json-response-for-rails-and-jquery

{
  status: "ok|redirect|error",
  to: "http://www.redirect-url.",
  html: "<b>Insert html</b>",
  message: "Insert some message here"
}

{
    "result": "false", 
    "fields":
        [
             {"id": "element1", "name": "element1"},
             {"id": "element2", "name": "element2"},
             {"id": "element3", "name": "element3"}
        ]
}

Hmm. I don't know about a standard, but you might want to just do something like

{
    "result": "false",
    "errors":
        [
             {"errorCode": "1234", "errorText": "malformed address"},
             {"errorCode": "5678", "errorText": "no username"}
        ]
}
