Class ElementProps

constructor

• new ElementProps(element: HTMLElement): ElementProps

  Construct the per-element collection and run the mount-time init pass. Pre-mount user writes (element.foo = …) and pre-mount attribute writes (setAttribute) leave traces on the element itself — a shadowing data property and an attribute, respectively — which each ElementProp's init pass picks up. So there's no separate initialize() step: the constructor allocates every wrapper and then runs init on each.

  The split is internal (allocate-all → init-all) so cascades during init always find existing wrappers in the Map — a wrapper materialized mid-cascade would fire its own default event in addition to the cascading update.

  Parameters

  • element: HTMLElement

    The element this collection belongs to.

  Returns ElementProps

element

ignoredAttributes

paused

• get paused(): boolean

  Whether propchange-style event dispatch is currently held. While true, fired events are queued; flipping to false flushes the queue in order.

  Returns boolean

• set paused(value: boolean): void

  Parameters

  • value: boolean

  Returns void

spec

• get spec(): Props

  Returns Props

  The class-level prop spec collection.

attributeChanged

• attributeChanged(name: string, oldValue?: string): void

  Propagate an observed attribute change to every prop reflected from it.

  Parameters

  • name: string

    Attribute name.

  • OptionaloldValue: string

  Returns void

get

• get(name: string): ElementProp

  Get the ElementProp wrapper for a prop by name, creating it on demand from this element's own class-level Props.

  Parameters

  • name: string

  Returns ElementProp

propChanged

• propChanged(ep: ElementProp, change: any): void

  Fire propchange events for ep and cascade updates to any dependents.

  Parameters

  • ep: ElementProp

    The prop that changed.

  • change: any

    Change descriptor (see ElementProp#set).

  Returns void
