$( 'a[href*="#"]:not([href="#"])' ).click( function() {
			var $this_link = $( this ),
				has_closest_smooth_scroll_disabled = $this_link.closest( '.et_smooth_scroll_disabled' ).length,
				has_closest_woocommerce_tabs = ( $this_link.closest( '.woocommerce-tabs' ).length && $this_link.closest( '.tabs' ).length ),
				has_closest_eab_cal_link = $this_link.closest( '.eab-shortcode_calendar-navigation-link' ).length,
