Fired from the field when its input is being manipulated. This can be useful for hiding the feedback while the user is typing into the field. This event is also fired when an error is returned by the API.

field.addEventListener('nb:clear', function(e) { // Get the ID for this field var id = e.detail.id; // Check for an API error if (e.detail.result && e.detail.result.isError()) { // Get error message var error = e.detail.error; } });
