我在shopify上遇到ajaxify购物车的问题。 添加产品时，更新购物车计数会很好，但是，只有在重新加载页面后，产品才会显示在购物车/抽屉购物车中。 我正在尝试立即更新购物车，而不必先重新加载页面。
我尝试将ajaxify脚本更改为/cart/update.js而不是/cart/add.js，但这没有用，并且产品也没有添加到购物车中。我还尝试将其设置为cart.js，它会更新购物车，但它也会转到购物车页面，而不是停留在产品页面上。
任何想法如何做到这一点？
我的Ajax代码如下：
<script>
window.onload = function() {
Shopify.AjaxifyCart = (function($) {
// Some configuration options.
// I have separated what you will never need to change from what
// you might change.
var _config = {
// What you might want to change
addToCartBtnLabel: 'Add to cart',
addedToCartBtnLabel: 'Thank you!',
addingToCartBtnLabel: 'Adding...',
soldOutBtnLabel: 'Sold Out',
howLongTillBtnReturnsToNormal: 1000, // in milliseconds.
cartCountSelector: '.CartCount',
cartTotalSelector: '#cart-price',
// 'aboveForm' for top of add to cart form,
// 'belowForm' for below the add to cart form, and
// 'nextButton' for next to add to cart button.
feedbackPosition: 'nextButton',
// What you will never need to change
addToCartBtnSelector: '[type="submit"]',
addToCartFormSelector: 'form[action="/cart/add"]',
shopifyAjaxAddURL: '/cart/add.js',
shopifyAjaxCartURL: '/cart.js'
};
// We need some feedback when adding an item to the cart.
// Here it is.
var _showFeedback = function(success, html, $addToCartForm) {
$('.ajaxified-cart-feedback').remove();
var feedback = '<p class="ajaxified-cart-feedback ' + success + '">' + html + '</p>';
switch (_config.feedbackPosition) {
case 'aboveForm':
$addToCartForm.before(feedback);
break;
case 'belowForm':
$addToCartForm.after(feedback);
break;
case 'nextButton':
default:
$addToCartForm.find(_config.addToCartBtnSelector).after(feedback);
break;
}
// If you use animate.css
// $('.ajaxified-cart-feedback').addClass('animated bounceInDown');
$('.ajaxified-cart-feedback').slideDown();
};
var _setText = function($button, label) {

$button.children().each(function() {

$(_config.cartCountSelector).html(value.replace(/[0-9]+/,cart.item_count)).removeClass('hidden-count');

<p><input type="hidden" name="id" value="{{ variant.id }}" /></p>
<div class="add-btn-container">

</button>

</form>
