        var data = {
          people: [
            { first_name: "rui", last_name: "fengyun", phone: "1234567890", email: "alan@test.com", member_since: "Mar 25, 2011" },
            { first_name: "Allison", last_name: "House", phone: "0987654321", email: "allison@test.com", member_since: "Jan 13, 2011" },
            { first_name: "Nick", last_name: "Pettit", phone: "9836592272", email: "nick@test.com", member_since: "Apr 9, 2009" },
            { first_name: "Jim", last_name: "Hoskins", phone: "7284927150", email: "jim@test.com", member_since: "May 21, 2010" },
            { first_name: "Ryan", last_name: "Carson", phone: "8263729224", email: "ryan@test.com", member_since: "Nov 1, 2008" }
          ]
        };
                                                                                                                                                                                                                                                                                                                                                                                                               
        $('#list').html(template(data));
      });
    </script>
  </body>
</html>

进行遍历里面的数据，print出来

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

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>
