/**
|
||
|
|
* @fileoverview Core of the JSON Form client-side library.
|
||
|
|
*
|
||
|
|
* Generates an HTML form from a structured data model and a layout description.
|
||
|
|
*
|
||
|
|
* The library may also validate inputs entered by the user against the data model
|
||
|
|
* upon form submission and create the structured data object initialized with the
|
||
|
|
* values that were submitted.
|
||
|
|
*
|
||
|
|
* The library depends on:
|
||
|
|
* - jQuery
|
||
|
|
* - the underscore library
|
||
|
|
* - a JSON parser/serializer. Nothing to worry about in modern browsers.
|
||
|
|
* - the JSONFormValidation library (in jsv.js) for validation purpose
|
||
|
|
*
|
||
|
|
* See documentation at:
|
||
|
|
* http://developer.joshfire.com/doc/dev/ref/jsonform
|
||
|
|
*
|
||
|
|
* The library creates and maintains an internal data tree along with the DOM.
|
||
|
|
* That structure is necessary to handle arrays (and nested arrays!) that are
|
||
|
|
* dynamic by essence.
