Produkt zum Warenkorb hinzufügen und entfernen Anzahl fehlt, während Elemente in opencart

Question

Ich benutze unten Skript zum Hinzufügen von Produkten zum Warenkorb und zu entfernen, wo im Display zählen, wie viele hinzugefügt und nach dem Entfernen, wie viele links ... in meinem Skript wenn ich zähle mich zu entfernen nicht angezeigt wird und nach der Seitenzahl erfrischend zeigt, wo ich Logik verpasst bin ...

// Cart add remove functions 
var cart = { 
    'add': function(product_id, quantity) {

ich glaube, Sie müssen Ihren Code in „entfernen“ Abschnitt ändern: ändern unter:

setTimeout(function() { 
        $('#cart > button').html('<i class="fa fa-shopping-basket"></i>Cart<span id="cart-total">' + total + '</span>'); 
       }, 100); 

Nach unten:

setTimeout(function() { 
        $('#cart > button').html('<span id="cart-total"><i class="fa fa-shopping-cart"></i> ' + json['total'] + '</span>'); 
       }, 100);
