FacetWP – show reset button only when facets are selected

<script>

/*
Code placement: see the "Javascript" section on https://facetwp.com/how-to-use-hooks/
This assumes that your reset button looks like this:

<a class="my-reset-btn" onclick="FWP.reset()">RESET</a>
*/

(function($) {
    $(document).on('facetwp-loaded', function() {
        var qs = FWP.build_query_string();
        if ( '' === qs ) { // no facets are selected
            $('.your-reset-btn').hide();
        }
        else {
            $('.your-reset-btn').show();
        }
    });
})(jQuery);
