API

If you just want an is-active class to be toggled on all inputs and textareas, you can just roll with the defaults.

isempty();

If you want to only run this functionality on a specific set of elements, you can supply a nodeList to the function. Optionally you can provide the config object as the second parameter.

isempty(document.querySelectorAll('.my-elements'), {
    'class': 'is-toggled'
});

If you do not provide a nodeList the fallback will be used.

document.querySelectorAll('textarea, input:not([type=hidden]):not([type="radio"]):not([type="checkbox"]):not([type="submit"]):not([type="button"])')

Additionally you have the option to specify the class you would like to toggle without specifying a set of elements, by just providing the options object.

isempty({
    'class': 'is-toggled'
});

You can manually check the inputs by just calling isempty(). The arguments you provided the first time will be stored and use for subsequent calls without any arguments.
