Options

The enableButtons function can take an object, that may include the following properties.

className

The class name that Enable Buttons uses to locate sections. Defaults to js-enable-buttons.

enableButtons({ className: 'my-special-class' })

Data attributes

ignore

If there is a button that you don't want Enable Buttons to do it's magic on, then you can add the data-ignore attribute to it.

<form class="js-enable-buttons">
  <input type="text" name="hello" required>

  <button type="submit" disabled>
    Submit
  </button>

  <button type="button" data-ignore="true">
    Don't touch me
  </button>
</form>

Browser support

Enable Buttons is packaged with Babel, and makes use of Array.from. If you want Enable Buttons to work on browsers that don't support this method (e.g. IE11), then you will need to polyfill Array.from before calling enableButtons.
