尝试分解/ script部分：

 < script ...> ;&LT; {{}！} /脚本&GT; 
 

该技术类似于旧版hack，比如

 <脚本>文件撰写（ <脚本> ...< \ /脚本> 中）;< /脚本> 
 

The description says it all. How to put a JavaScript script inside handlebars template.

I want to make a dynamic Paypal button for my website.

      <script type="text/x-mustache-template" id="product-item-thumbnail-template">
      <h2>{{title}}</h2>
      <p>{{message}}</p>
      <p><a class="btn" href="#">View details &raquo;</a></p>
      <p><script src="resources/js-frameworks/paypal-button.min.js?merchant=myemail@GMAIL.COM"
            data-button="buynow"
            data-name="My product"
            data-amount="1.00"></script></p>
</script>

But this produces an error because of the tag. it closes the template script and not the paypal script

Thanks

Try breaking up the "/script" part:

<script ...><{{!}}/script>

That technique is similar to older hacks like

<script>document.write("<script>...<\/script>");</script>
