How to make auto-refresh in the cart when you click +/-?

Question

JavaScript

Hello.
Can you please tell me how to update the cart automatically?
I found a code that works on manual input in the .qtu field, but due to my poor knowledge of js, I can’t add an update by clicking on +/- in any way. Our buttons are custom, so there are such problems.

add_action( 'wp_footer', 'cart_update_qty_script' );
function cart_update_qty_script() {
    if (is_cart()) :
    ?>
    <script>
        jQuery('div.woocommerce').on('change', '.qty', function(){
            jQuery("[name='update_cart']").trigger("click"); 
        });
    </script>
    <?php
    endif;
}

html block increase quantity

<div class="quantity">
     <input type="number" class="input-text qty text" step="1" value="3" title="Количество" size="4" placeholder="" inputmode="numeric">

     <input type="button" value="+" class="lafka-qty-plus">
     <input type="button" value="-" class="lafka-qty-minus"> 
</div>

Answer 1

Try Ajax Cart AutoUpdate for WooCommerce Plugin

Answer 2

jQuery('.lafka-qty-plus, .lafka-qty-minus').on('click', function() {
    jQuery("[name='update_cart']").trigger("click"); 
})
