我想在結帳總金額上有一個零，因為在末端以零結尾的產品上，總金額顯示為這樣￡1.5那么，如何更改它以像這樣顯示1.50英鎊而不會弄亂其他產品呢？任何代碼片段都將不勝感激。<!DOCTYPE html><html><head> </head><body><header class="main-header"> <nav class="main-nav nav"> </nav></header> <div class="shop-items"> <div class="shop-item"> <span class="shop-item-title">Album 0</span>  <div class="shop-item-details"><span class="shop-item-price">￡12.50</span> <button class="btn btn-primary shop-item-button" type="button">ADD TO BASKET</button> </div> <div class="shop-item"> <span class="shop-item-title">Album 2</span>  <div class="shop-item-details"> <span class="shop-item-price">￡14.50</span> <button class="btn btn-primary shop-item-button" type="button">ADD TO BASKET</button> </div> <div class="shop-item"> <span class="shop-item-title">Album 4</span>  <div class="shop-item-details"><span class="shop-item-price">￡19.50</span> <button class="btn btn-primary shop-item-button" type="button">ADD TO BASKET</button> </div> </div></section> <div class="shop-items"> <div class="shop-item"> <span class="shop-item-title">Album 6</span>  <div class="shop-item-details"><span class="shop-item-price">￡19.50</span> <button class="btn btn-primary shop-item-button" type="button">ADD TO BASKET</button> </div> <div class="shop-items"> <div class="shop-item"> <span class="shop-item-title">Album 8</span>  <div class="shop-item-details"><span class="shop-item-price">￡19.50</span> <button class="btn btn-primary shop-item-button" type="button">ADD TO BASKET</button> </div>

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)

}
