如何在handlebars.js中使用一个模板，同时在其中使用多个对象？

<script id="my-template" type="text/x-handlebars-template">
  <h1>{{title}}</h1>
  <p>Author: {{author.name}}</p>
  <p>Published: {{publishedDate}}</p>
  <h2>Comments:</h2>
  {{#each comments}}
    <p>{{this}}</p>
  {{/each}}
</script>

// 数据对象
var data = {
  title: "Handlebars.js Demo",
  author: {
    name: "John Doe"
  },
  publishedDate: "2022-01-01",
  comments: [
    "Great article!",
    "Thanks for sharing.",
    "I learned a lot."
  ]
};

// 编译模板
var template = Handlebars.compile(document.getElementById("my-template").innerHTML);

// 生成HTML代码
var html = template(data);

// 将HTML代码插入到页面中
document.getElementById("output").innerHTML = html;

<h1>Handlebars.js Demo</h1>
<p>Author: John Doe</p>
<p>Published: 2022-01-01</p>
<h2>Comments:</h2>
<p>Great article!</p>
<p>Thanks for sharing.</p>
<p>I learned a lot.</p>
