Form builder like Zend_Form_Html or ExtJS Form for JQuery

Question

I was wondering if there is a JavaScript based HTML Form builder, similar to what you can do with Zend_Form_Html or with the ExtJS Forms but based on JQuery? There are several form related plugins but you still have to code every form manually. The idea is, that I usually only want to edit/add single entities from my Domain Model (e.g. in Doctrine with PHP), lets say a new user. I have the user as a JSON Object

{
    'username': 'John',
    'email': '[email protected]',
    'name': 'John Doe'
    'age': '33'
}

And I could also make some meta information available (e.g. the Database knows already that age must be an Integer so I already can attach that client side validator or display a nice number spinner).

{
    'entity': 'User',
    'email': 
     {
      'type': 'text',
      'validate': 'e-mail',
      'max_lengh': 255
     },
    'name': 
     {
      'type': 'text',
      'validate': 'string',
      'max_lengh': 255
     },
    'age': 
     {
      'type': 'spinner',
      'validate': 'integer',
      'range': [0, 120]
     }
}

With this information you could already build a scaffold form so that you only have to add/edit the additional information needed. On my quick search I unfortunately didn't find anything like that.

I don't think there is one for jQuery that supports JSON input, but take a look at:

Answer 2

Since nothing like this popped up yet, I started my own project on github (moved from Google code) called jquery.dform. It is a jQuery plugin for creating html forms via JSON.

It is still in its early development stages but it is starting to get things done.
