Accessing product data in checkout.liquid Shopify

Hello,

please ensure, your store is Shopify PLUS.

it seems that the global liquid variables  all_products and collections are not available in the checkout.liquid file. 

So you can grab data using the following code

<script>

jQuery.getJSON('/products/<product_handle>.js', function(product) {
  alert('The title of this product is ' + product.title);
});

</script>

Please make sure you have added jQuery before this script

Thanks,

Enjoy :)
