Callback/validation tips for jeditable

Any tips for form validation using jeditable. I would like to have the script POSTed to pass back errors with JSON, with the submitted text but can't seem to figure that one out, if even possible. Or h开发者_运维技巧ow to check text as it's being inputed via onChange.

Thx

Here is a simple sample, but not used jQuery Validation.

function isNumeric(value) {
  if (value == null || !value.toString().match(/^[-]?\d*\.?\d*$/)) return false;
  return true;
}

$('.edit').editable(your_url, {
    onsubmit: function(settings, original) {
        if (isNumeric(original)) {
            return true;
        } else {
            //display your message
            return false;
        }
    }
});
