    var form = $(this);

})(jQuery)

Thanks :D

nice

I made a plugin that is similar to this: https://github.com/marioizquierdo/jquery.serializeJSON

It uses serializeArray under the hood, that handles the field conversion for you, then enhances to support nested attributes and arrays in the json output.

dont support textarea elements
