  </body>
</html>
<script id="each-template" type="text/x-handlebars-template">
  {{#each people}}
    ... output person's info here...
  {{/each}}
</script>

进行遍历里面的数据，print出来

有数据的话，进行数据渲染

<script id="each-template" type="text/x-handlebars-template">
  {{#if people}}
    ... output person's info here...
  {{/if}}
</script>

没有数据的话，就写没有数据

<script id="each-template" type="text/x-handlebars-template">
  {{#unless people.length}}
    There aren't any people.
  {{/unless}}
</script>

if else 关联的判断

<script id="each-template" type="text/x-handlebars-template">
  {{#if people.length}}
    ... output person's info here...
  {{else}}
    There aren't any people.
  {{/if}}
</script>
