Adds / removes DOM sub-trees based on a numeric value. Tailored for pluralization.
Displays DOM sub-trees that match the switch expression value, or failing that, DOM sub-trees that match the switch expression's pluralization category.
To use this directive you must provide a container element that sets the
[ngPlural] attribute to a switch expression. Inner elements with a
[ngPluralCase] will display based on their expression:
[ngPluralCase]is set to a value starting with
=, it will only display if the value matches the switch expression exactly,
- otherwise, the view will be treated as a "category match", and will only display if exact value matches aren't found and the value maps to its category for the defined locale.
<some-element [ngPlural]="value"> <ng-template ngPluralCase="=0">there is nothing</ng-template> <ng-template ngPluralCase="=1">there is one</ng-template> <ng-template ngPluralCase="few">there are a few</ng-template> </some-element>
