在代碼末尾，將此代碼編輯為totaltotal.toFixed(2)


編輯：


在代碼的最后一行


function updateCartTotal() {

var cartItemContainer = document.getElementsByClassName('cart-items')[0]

var cartRows = cartItemContainer.getElementsByClassName('cart-row')

var total = 0

for (var i = 0; i < cartRows.length; i++) {

    var cartRow = cartRows[i]

    var priceElement = cartRow.getElementsByClassName('cart-price')[0]

    var quantityElement = cartRow.getElementsByClassName('cart-quantity-input')[0]

    var price = parseFloat(priceElement.innerText.replace('￡', ''))

    var quantity = quantityElement.value

    total = total + (price * quantity)

}

total = Math.round(total * 100) / 100

document.getElementsByClassName('cart-total-price')[0].innerText = '￡' + total.toFixed(2)

}
