Displaying a List of Items


If you need to enumerate over a list of objects, use Handlebars' {{#each}} helper:

<ul>
  {{#each person in people}}
    <li>Hello, {{person.name}}!</li>
  {{/each}}
</ul>

The template inside of the {{#each}} block will be repeated once for each item in the array, with the each item set to the person keyword.

The above example will print a list like this:

<ul>
  <li>Hello, Yehuda!</li>
  <li>Hello, Tom!</li>
  <li>Hello, Trek!</li>
</ul>

Like everything in Handlebars, the {{#each}} helper is bindings-aware. If your application adds a new item to the array, or removes an item, the DOM will be updated without having to write any code.

The {{#each}} helper can have a matching {{else}}. The contents of this block will render if the collection is empty:

{{#each person in people}}
  Hello, {{person.name}}!
{{else}}
  Sorry, nobody is here.
{{/each}}
