Woocommerce：如何获得变化的库存状态

Question

I have this function to personalize my product page a little. Inside my child-themes function.php I added this:

function change_product_summary_germanized(){
    global $product;

    if ($product->is_type('variable')) {

        $shopmarks = wc_gzd_get_single_product_shopmarks();

        foreach ($shopmarks as $shopmark) {
            $type = $shopmark->get_type();
            switch ($type) {
                case 'unit_price':
                    $shopmark->remove();
                    add_action('woocommerce_before_single_variation', 'woocommerce_gzd_template_single_price_unit', 20);
                    add_action('woocommerce_before_single_variation', 'custom_unit_price_title', 19);
                    break;
                case 'legal':
                    $shopmark->remove();
                    add_action('woocommerce_before_single_variation', 'woocommerce_gzd_template_single_legal_info', 40);
                    break;
                case 'delivery_time':
                    $shopmark->remove();
                    // if ( $product->is_in_stock() ) {
                        add_action('woocommerce_before_single_variation', 'woocommerce_gzd_template_single_delivery_time_info', 50);
                    // }
                    break;

            }
        }
    }
}
add_filter('woocommerce_single_product_summary', 'change_product_summary_germanized');

Works fine but as you can see I commented out an if-clause that I am having trouble with. I tried all different kinds of ways to not add the delivery-time, when the selected variation is out of stock.

Examples of what I have tried so far:

if( $product->is_in_stock() ) {...}
if( $product->get_stock_quantity() > 0 ) {...}
if( sizeof($product->get_available_variations()) > 0) {...}

...

I am pretty new to this. Anybody can point out to me, what's the way to go here?

Many may agree that this is terrible work, but I achieved what I wanted on a complicated way. A few months ago I built a function to get product-prices on my own way. It's leaned on something I found online, but I can't find the reference anymore. Anyway, I added some JQuery to hide/show elements depending on if other elements are visible.

function custom_wc_template_single_price(){
global $product;
if ($product->is_type('variable')):
    $prices = array(
        $product->get_variation_price('min', true),
        $product->get_variation_price('max', true)
    );
    $price = $prices[0] !== $prices[1] ? sprintf(__('ab %1$s', 'woocommerce'), wc_price($prices[0])) : wc_price($prices[0]);
    $prices = array(
        $product->get_variation_regular_price('min', true),
        $product->get_variation_regular_price('max', true)
    );
    sort($prices);
    $saleprice = $prices[0] !== $prices[1] ? sprintf(__('ab %1$s', 'woocommerce'), wc_price($prices[0])) : wc_price($prices[0]);

    if ($price !== $saleprice && $product->is_on_sale()) {
        $price = '<del>' . $saleprice . $product->get_price_suffix() . '</del> <ins>' . $price . $product->get_price_suffix() . '</ins>';
    }

    ?>
    <style>
        div.woocommerce-variation-price,
        div.woocommerce-variation-availability,
        div.hidden-variable-price {

            overflow: hidden;

                        $('div.legal-price-info').append('<p class="availability">' + $('div.woocommerce-variation-availability').html() + '</p>');
                    }
