propertyDefaults

  • Edit on GitHub

Specify default behaviors for properties on a ObservableArray.

static propertyDefaults = PROPDEFINITION

Specify default values using a [can-observable-object/object.types.propDefinition] object.

import { ObservableArray, ObservableObject, type } from "can/everything";

class Player extends ObservableObject {

}

class Players extends ObservableArray {
  static propertyDefaults = {
    type: type.convert(Number)
  };

  static items = Player;
}

const team = new Players();
team.rank = "5";

console.log(team.rank); // -> 5

The above specifies a RouteData type whose properties default to a strictly typed String and are non-enumerable.

static propertyDefaults = PROPERTY

propertyDefaults can be specified using any of the methods specified by the property type.

import { ObservableArray } from "can/everything";

class People extends ObservableArray {
  static propertyDefaults = String;
}

The above specifies all properties to default to being a strictly defined String. See Property for other possible values.

This does not set the type for items within the array. Use items for that.
