{{#with(expression)}}

  • Edit on GitHub

Changes the context within a block.

{{#with(EXPRESSION)}}BLOCK{{/with}}

Renders BLOCK with the result of EXPRESSION added to the top of the can-view-scope.

{{#with(person.address)}}
    Street: {{street}}
    City: {{city}}
{{/with}}

Parameters

  1. EXPRESSION {KeyLookup Expression|Call Expression}:

    A lookup expression that will provide a value.

  2. BLOCK {sectionRenderer(context, helpers)}:

    A template that is rendered with the context of the EXPRESSION’s value.

{{#with(HASHES)}}BLOCK{{/with}}

Renders BLOCK with the key-value pairs from a Hash Expression added to the top of the can-view-scope.

{{#with(innerStreet=person.address.street innerCity=person.address.city)}}
    Street: {{innerStreet}}
    City: {{innerCity}}
{{/with}}

Parameters

  1. HASHES {Hash Expression}:

    Any number of hash keys and values

  2. BLOCK {sectionRenderer(context, helpers)}:

    A template that is rendered with the hashes added to the context.

Use

{{#with()}} renders a subsection with a new context added to the can-view-scope. For example:

<!-- Template -->
{{#with(person.address)}}
    Street: {{street}}
    City: {{city}}
{{/with}}
/* Data */
{person: {address: {street: "123 Evergreen", city: "Springfield"}}}
<!-- Result -->
Street: 123 Evergreen
City: Springfield

The new context can be a lookup expression, or a set of hashes which are taken together to be a new context.

<!-- Template -->
{{#with(innerStreet=person.address.street innerCity=person.address.city)}}
    Street: {{innerStreet}}
    City: {{innerCity}}
{{/with}}
/* Data */
{person: {address: {street: "123 Evergreen", city: "Springfield"}}}
<!-- Result -->
Street: 123 Evergreen
City: Springfield

The difference between {{#with()}} and the default {{#expression}} is that the subsection BLOCK is rendered no matter what:

<!-- Template -->
{{#with(person.address)}}
    Street: {{street}}
    City: {{city}}
{{/with}}
/* Data */
{person: {}}
<!-- Result -->
Street:
City:
