An abstract pattern for defining an Application responsible for updating some object using an HTML form

A few critical assumptions:

  1. This application is used to only edit one object at a time
  2. The template used contains one (and only one) HTML form as it's outer-most element
  3. This abstract layer has no knowledge of what is being updated, so the implementation must define _updateObject
abstract
interface
param object

Some object which is the target data structure to be updated by the form.

param [options]

Additional options which modify the rendering of the sheet.

Constructors

Properties

object: any

The object target which we are using this form to modify

form: HTMLElement

A convenience reference to the form HTMLElement

filepickers: FilePicker[]

Keep track of any FilePicker instances which are associated with this form The values of this Array are inner-objects with references to the FilePicker instances and other metadata

editors: Object

Keep track of any mce editors which may be active as part of this form The values of this object are inner-objects with references to the MCE editor and other metadata

_submitting: boolean
_state: any

The current render state of the Application

options: any

The options provided to this application upon initialization

appId: number

The application ID is a unique incrementing integer which is used to identify every application window drawn by the VTT

_element: jQuery

An internal reference to the HTML element this application renders

position: any

Track the current position and dimensions of the Application UI

_dragDrop: DragDrop[]

DragDrop workflow handlers which are active for this Application

{Application.RENDER_STATES}

RENDER_STATES: Readonly<{ CLOSING: -2; CLOSED: -1; NONE: 0; RENDERING: 1; RENDERED: 2; ERROR: 3 }> = ...

The sequence of rendering states that track the Application life-cycle.

Accessors

  • get isEditable(): boolean
  • Is the Form Application currently editable?

    Returns boolean

  • get id(): string
  • Return the CSS application ID which uniquely references this UI element

    Returns string

  • get element(): jQuery
  • Return the active application element, if it currently exists in the DOM

    Returns jQuery

  • get template(): string
  • The path to the HTML template file which should be used to render the inner content of the app

    Returns string

  • get popOut(): boolean
  • Control the rendering style of the application. If popOut is true, the application is rendered in its own wrapper window, otherwise only the inner app content is rendered

    Returns boolean

  • get rendered(): boolean
  • Return a flag for whether the Application instance is currently rendered

    Returns boolean

  • get title(): string
  • An Application window should define its own title definition logic which may be dynamic depending on its data

    Returns string

  • Assign the default options which are supported by the document edit sheet. In addition to the default options object supported by the parent Application class, the Form Application supports the following additional keys and values:

    Returns ApplicationOptions

    The default options for this FormApplication class

Methods

  • getData(options?: {}): any
  • An application should define the data object used to render its template. This function may either return an Object directly, or a Promise which resolves to an Object If undefined, the default implementation will return an empty object allowing only for rendering of static HTML

    Parameters

    • options: {} = {}

      Returns any

    • _render(force: any, options: any): Promise<void>
    • An asynchronous inner function which handles the rendering of the Application

      Parameters

      • force: any

        Render and display the application even if it is not currently displayed.

      • options: any

        Additional options which update the current values of the Application#options object

      Returns Promise<void>

      A Promise that resolves to the Application once rendering is complete

    • _renderInner(...args: any[]): Promise<jQuery>
    • Render the inner application content

      Parameters

      • Rest ...args: any[]

        The data used to render the inner template

      Returns Promise<jQuery>

      A promise resolving to the constructed jQuery object

    • _activateCoreListeners(html: any): void
