Question about uikit and JS. How to get the data value of the element a, in the event of the modal window "show.uk.modal"?

Question

JavaScript

Best wishes to all!
Call modal window on click on link

<a href="#modalAuth" data-type="REGISTRATION" data-uk-modal="{center:true}">Регистрация <i class="uk-icon-user-plus"</a>
<a href="#modalAuth" data-type="AUTH" data-uk-modal="{center:true}">Войти <i class="uk-icon-sign-in"></i></a>

How can I now get the data-type value from the clicked link in the "show.uk.modal" event?

$('#modalAuth').on({
        'show.uk.modal':function(modal){
            var type =????;
            console.log(type);
        },
        'hide.uk.modal': function(){}
    });
