Settings

Set these settings on a DateFormatter object using its set() and setAll() methods.

Read about settings concept.

animations
#

Type Array

Inherited from IEntitySettings

Animations the element plays on its own, described as data - so they can be set from a JSON config and saved with it.

Each one animates a setting of the element (or, with target: "dataItem", a value of its data item - a map point's positionOnLine, say). They start when the setting is applied, restart when it changes, and stop when the element is disposed. A saved config keeps what was configured, never a value caught half way through an animation.

sprite.set("animations", [
  { key: "rotation", to: 360, duration: 4000, loops: 0 },
  { key: "scale", from: 1, to: 1.3, duration: 800, loops: 0, yoyo: true, easing: "sine" }
]);

@since 5.20.8

capitalize
#

Type undefined | false | true

Default true

Capitalizes the first letter of the formatted date.

#

Type string[]
