Displaying a List of Items Edit Page

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

1
2
3
4
5

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

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

The above example will print a list like this:

1
2
3
4
5

<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.

There is an alternative form of {{#each}} that does not change the scope of its inner template. This is useful for cases where you need to access a property from the outer scope within the loop.

1
2
3
4
5
6
7

{{name}}'s Friends

<ul>
  {{#each friend in friends}}
    <li>{{name}}'s friend {{friend.name}}</li>
  {{/each}}
</ul>

This would print a list like this:

1
2
3
4
5
6

Trek's Friends

<ul>
  <li>Trek's friend Yehuda</li>
  <li>Trek's friend Tom!</li>
</ul>

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

1
2
3
4
5

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