i have a json file:
{
\"data\": \"Click\",
\"size\": \"Here\" }
and a form:
Could you take a look at the JQuery loadJSON plugin on the http://code.google.com/p/jquery-load-json/ ? On the page http://code.google.com/p/jquery-load-json/wiki/WorkingWithFormElements is explained how this plugin load JSON object into the form. You can also find one live example here http://jquery-load-json.googlecode.com/svn/trunk/edit.html?ID=17. I think that this is exactly what you need. Just create empty form and load json in the form using the following code:
$('form').loadJSON(data);
This plugin handles all form elements such as check boxes, select list radio buttons etc. If you use it you will need to download plugin from the http://code.google.com/p/jquery-load-json/source/browse/trunk/scripts/jquery.loadJSON.js.
