车把js如果条件

Question

My json part:

var context = {
  author: [{
  id: 47,
  name: "Yehuda Katz"
},
{
  id: 48,
  name: "Kate"
},

{ id: 49, name: "Jim" }

]}

Handlebars

{{if author}}
 <li>{{id}}</li>
 <li>{{name}}</li>
{{/if}}

I want to display the contents once author key is present. If not,it won't display.

However,my above code doen't displays the author eventhough it is present.

Whats wrong in my code??

Answer 1

Handlebars block helpers (like if) need a hash character before the block statment

so instead of

{{if author}}
 <li>{{id}}</li>
 <li>{{name}}</li>
{{/if}}

do

{{#if author}}
 <li>{{id}}</li>
 <li>{{name}}</li>
{{/if}}
