中的Javascript变量<script> tag

Question

My knowledge of javascript is medium, sorry if this question seem too newbie

I call a (stripe) script to display the checkout, my 'desc' variable, which is properly in my page, is just not used in the tag. Instead I have 'desc'.

data-description='bonjour' works

var desc = 'bonjour' data-description=desc does not work

what am I missing here ?

<script
      src="https://checkout.stripe.com/checkout.js" class="stripe-button"
      data-key=""
      data-amount=amount
      data-name="<%= current_user.full_name %>"
      data-description=desc
      data-panel-label="Encaisser"
      data-label="Payer par carte"
      data-image="https://stripe.com/img/documentation/checkout/marketplace.png"
      data-locale="fr"
      data-currency="eur">
    </script>

Answer 1

实际上，那里没有任何Javascript-您只有HTML标记，描述了script标签及其HTML属性 ，因此您不能使用var或Javascript的其他特定功能。

Answer 2

<script no javascript here because this is HTML, not JS>
  JS can only be used here, in the content of the script tag
</script>
