public class ChooseHelper extends BasicSectionHelper
This helper should only contain when and otherwise sections. Other types of segments are always rendered.
Since we push the flow object on the context stack, it's possible to refer
the last context object with Nested.up() method. See also examples.
{{#choose}}
{{#when this.up}}
Hello active!
{{/when}}
{{#when foo}}
Hello foo!
{{/when}}
{{#otherwise}}
No match.
{{/otherwise}}
{{/choose}}
will render "Hello active!" if last context object (i.e. "this" before we
enter the choose helper) is not falsy. "Hello foo" if "this.up" is falsy and
"foo" is not falsy. And "No match." if both "this.up" and "foo" are falsy.| Modifier and Type | Class and Description |
