Here’s how to clear form values with jQuery.

var clearAllFormValues = function() {
  $('input,textarea')
    .not('input[type=\\"radio\\"],input[type=\\"checkbox\\"],:hidden, :button, :submit,:reset')
    .val('');
  $('input[type=\\"radio\\"], input[type=\\"checkbox\\"],select')
    .removeAttr('checked')
    .removeAttr('selected');
}

// Clear form values within div#modal-area
var clearModalAreaFormValues = function() {
  $('#modal-area')
    .find('input,textarea')
    .not('input[type=\\"radio\\"],input[type=\\"checkbox\\"],:hidden, :button, :submit,:reset')
    .val('');
  $('#modal-area')
    .find('input[type=\\"radio\\"], input[type=\\"checkbox\\"],select')
    .removeAttr('checked')
    .removeAttr('selected');
}

That’s all from the Gemba.
