Hello guys,

i have this problem with JS on my portal. When using 

element.innerHTML = '';

for creating new elements. After saving the code in code editor on portal the part after "element.innerHTML" just cuts off. Here's the code that works on my local: 

for (let i = 0; i < itemsCount; i++) {
          let parentElement = document.body;
          let element = document.createElement("div");
          element.setAttribute("class", "item");

          var name = items[i].name;
          var price = items[i].price;
          var desc = items[i].desc;
          var img = items[i].img;
          var qty = items[i].qty;

          element.innerHTML = '<div class="image"><img src=' + img + ' alt="" /></div><div class="description"><span>' + name + '</span><span>TICKET</span></div><div class="quantity"><button class="plus-btn" type="button" name="button"><svg xmlns="http://www.w3.org/2000/svg" width="16" height="16" fill="currentColor" class="bi bi-plus" viewBox="0 0 16 16"><path d="M8 4a.5.5 0 0 1 .5.5v3h3a.5.5 0 0 1 0 1h-3v3a.5.5 0 0 1-1 0v-3h-3a.5.5 0 0 1 0-1h3v-3A.5.5 0 0 1 8 4z"/></svg></button><input type="text" name="name" value="' + qty + '"><button class="minus-btn" type="button" name="button"><svg xmlns="http://www.w3.org/2000/svg" width="16" height="16" fill="currentColor" class="bi bi-dash" viewBox="0 0 16 16"><path d="M4 8a.5.5 0 0 1 .5-.5h7a.5.5 0 0 1 0 1h-7A.5.5 0 0 1 4 8z"/></svg></button></div><div class="total-price">$' + price + '</div>';

          document.getElementById("parent").append(element);
        }

Does anyone know what to do with this or how do I write this code without "" and '' because dataverse doesnt seem to like it.
