how to create a html form using a JSON definition?

I am looking for a javascript lib which enables me to store (html) forms in JSON format, with a bit of intelligence built into validate inputs client side. Something like:

function FormController(){
  this.user = {
    name: 'John Smith',
    address:{line1: '123 Main St.', city:'Anytown', state:'AA', zip:'12345'},
    contacts:[{type:'phone', value:'1(234) 555-1212'}]
  };
  this.state = /^\w\w$/;
  this.zip = /^\d\d\d\d\d$/;
}

(This is taken from http://docs.angularjs.org/#!cookbook.form ). It's almost what I want, as it offers basic client side validation with regular expressions and you can provide defaults but it appears to still need you to create the HTML form.

I want something that only requires the definition. Any ideas?
