我想在结帐总金额上有一个零，因为在末端以零结尾的产品上，总金额显示为这样 £1.5那么，如何更改它以像这样显示1.50英镑而不会弄乱其他产品呢？任何代码片段都将不胜感激。<!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>

在代码末尾，将此代码编辑为totaltotal.toFixed(2)
编辑：
在代码的最后一行
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)
}
