Properties

Property	Description
@Input()ngSwitchCase: any	Stores the HTML template to be selected on match.

Description

Within a switch container, *ngSwitchCase statements specify the match expressions as attributes. Include *ngSwitchDefault as the final case.

<container-element [ngSwitch]="switch_expression">
  <some-element *ngSwitchCase="match_expression_1">...</some-element>
  ...
  <some-element *ngSwitchDefault>...</some-element>
</container-element>

Each switch-case statement contains an in-line HTML template or template reference that defines the subtree to be selected if the value of the match expression matches the value of the switch expression.

Unlike JavaScript, which uses strict equality, Angular uses loose equality. This means that the empty string, "" matches 0.
