WjCalendar Class

Angular 2 component for the wijmo.input.Calendar control.

Use the wj-calendar component to add Calendar controls to your Angular 2 applications. For details about Angular 2 markup syntax, see Angular 2 Markup.

The WjCalendar component is derived from the Calendar control and inherits all its properties, events and methods.

Hierarchy

Properties

asyncBindings

asyncBindings: boolean

Allows you to override the global WjOptions.asyncBindings setting for this specific component. See the WjOptions.WjOptions.asyncBindings property description for details.

displayMonth

displayMonth: Date

Gets or sets the month displayed in the calendar.

displayMonthChangedNg

displayMonthChangedNg: EventEmitter<any>

Angular (EventEmitter) version of the Wijmo displayMonthChanged event for programmatic access. Use this event name if you want to subscribe to the Angular version of the event in code. In template bindings use the conventional displayMonthChanged Wijmo event name.

firstDayOfWeek

firstDayOfWeek: number

Gets or sets a value that represents the first day of the week, the one displayed in the first column of the calendar.

Setting this property to null causes the calendar to use the default for the current culture. In the English culture, the first day of the week is Sunday (0); in most European cultures, the first day of the week is Monday (1).

formatDayHeaders: string

Gets or sets the format used to display the headers above the days in month view.

The default value for this property is 'ddd'.

formatDays

formatDays: string

Gets or sets the format used to display the days in month view.

The default value for this property is 'd ' (the space after the 'd' prevents the format from being interpreted as 'd', the standard format used to represent the short date pattern).

formatItemNg

formatItemNg: EventEmitter<any>

Angular (EventEmitter) version of the Wijmo formatItem event for programmatic access. Use this event name if you want to subscribe to the Angular version of the event in code. In template bindings use the conventional formatItem Wijmo event name.

hostElement

hostElement: HTMLElement

Gets the DOM element that is hosting the control.

initialized

initialized: EventEmitter<any>

This event is triggered after the component has been initialized by Angular, that is all bound properties have been assigned and child components (if any) have been initialized.

isDisabled

isDisabled: boolean

Gets or sets a value that determines whether the control is disabled.

Disabled controls cannot get mouse or keyboard events.

isInitialized

isInitialized: boolean

Indicates whether the component has been initialized by Angular. Changes its value from false to true right before triggering the initialized event.

isUpdating: boolean

Gets a value that indicates whether the control is currently being updated.

itemFormatter

itemFormatter: Function

Gets or sets a formatter function to customize dates in the calendar.

The formatter function can add any content to any date. It allows complete customization of the appearance and behavior of the calendar.

If specified, the function takes two parameters:

  • the date being formatted
  • the HTML element that represents the date

For example, the code below shows weekends with a yellow background:

calendar.itemFormatter = function(date, element) {
  var day = date.getDay();
  element.style.backgroundColor = day == 0 || day == 6 ? 'yellow' : '';
}

itemValidator

itemValidator: Function

Gets or sets a validator function to determine whether dates are valid for selection.

If specified, the validator function should take one parameter representing the date to be tested, and should return false if the date is invalid and should not be selectable.

For example, the code below shows weekends in a disabled state and prevents users from selecting those dates:

calendar.itemValidator = function(date) {
  var weekday = date.getDay();
  return weekday != 0 && weekday != 6;
}

lostFocusNg

lostFocusNg: EventEmitter<any>

Gets or sets the template used to instantiate Calendar controls.

Methods

applyTemplate

  • applyTemplate(classNames: string, template: string, parts: Object, namePart?: string): HTMLElement
  • Applies the template to a new instance of a control, and returns the root element.

    This method should be called by constructors of templated controls. It is responsible for binding the template parts to the corresponding control members.

    For example, the code below applies a template to an instance of an InputNumber control. The template must contain elements with the 'wj-part' attribute set to 'input', 'btn-inc', and 'btn-dec'. The control members '_tbx', '_btnUp', and '_btnDn' will be assigned references to these elements.

    this.applyTemplate('wj-control wj-inputnumber', template, {
      _tbx: 'input',
      _btnUp: 'btn-inc',
      _btnDn: 'btn-dec'
    }, 'input');

    Parameters

    • classNames: string

      Names of classes to add to the control's host element.

    • template: string

      An HTML string that defines the control template.

    • parts: Object

      A dictionary of part variables and their names.

    • Optional namePart: string

      Name of the part to be named after the host element. This determines how the control submits data when used in forms.

    Returns HTMLElement

beginUpdate

  • beginUpdate(): void

created

  • created(): void
  • If you create a custom component inherited from a Wijmo component, you can override this method and perform necessary initializations that you usually do in a class constructor. This method is called in the last line of a Wijmo component constructor and allows you to not declare your custom component's constructor at all, thus preventing you from a necessity to maintain constructor parameters and keep them in synch with Wijmo component's constructor parameters.

    Returns void

deferUpdate

  • deferUpdate(fn: Function): void
  • Executes a function within a beginUpdate/endUpdate block.

    The control will not be updated until the function has been executed. This method ensures endUpdate is called even if the function throws an exception.

    Parameters

    • fn: Function

      Function to be executed.

    Returns void

endUpdate

  • endUpdate(): void

focus

  • focus(): void
  • Sets the focus to this control.

    Returns void

getTemplate

  • getTemplate(): string
  • Gets the HTML template used to create instances of the control.

    This method traverses up the class hierarchy to find the nearest ancestor that specifies a control template. For example, if you specify a prototype for the ComboBox control, which does not specify a template, it will override the template defined by the DropDown base class (the nearest ancestor that does specify a template).

    Returns string

hasOwnProperty

  • hasOwnProperty(v: PropertyKey): boolean
  • Determines whether an object has a property with the specified name.

    Parameters

    • v: PropertyKey

      A property name.

    Returns boolean

initialize

  • initialize(options: any): void
  • Initializes the control by copying the properties from a given object.

    This method allows you to initialize controls using plain data objects instead of setting the value of each property in code.

    For example:

    grid.initialize({
      itemsSource: myList,
      autoGenerateColumns: false,
      columns: [
        { binding: 'id', header: 'Code', width: 130 },
        { binding: 'name', header: 'Name', width: 60 }
      ]
    });
    // is equivalent to
    grid.itemsSource = myList;
    grid.autoGenerateColumns = false;
    // etc.
    

    The initialization data is type-checked as it is applied. If the initialization object contains unknown property names or invalid data types, this method will throw.

    Parameters

    • options: any

      Object that contains the initialization data.

    Returns void

invalidate

  • invalidate(fullUpdate?: boolean): void
  • Invalidates the control causing an asynchronous refresh.

    Parameters

    • Optional fullUpdate: boolean

      Whether to update the control layout as well as the content.

    Returns void

isPrototypeOf

  • isPrototypeOf(v: Object): boolean
  • Determines whether an object exists in another object's prototype chain.

    Parameters

    • v: Object

      Another object whose prototype chain is to be checked.

    Returns boolean

onDisplayMonthChanged

onFormatItem

onGotFocus

onLostFocus

onRefreshed

onRefreshing

onValueChanged

propertyIsEnumerable

  • propertyIsEnumerable(v: PropertyKey): boolean
  • Determines whether a specified property is enumerable.

    Parameters

    • v: PropertyKey

      A property name.

    Returns boolean

removeEventListener

  • removeEventListener(target?: EventTarget, type?: string, fn?: any, capture?: boolean): number
  • Removes one or more event listeners attached to elements owned by this Control.

    Parameters

    • Optional target: EventTarget

      Target element for the event. If null, removes listeners attached to all targets.

    • Optional type: string

      String that specifies the event. If null, removes listeners attached to all events.

    • Optional fn: any

      Handler to remove. If null, removes all handlers.

    • Optional capture: boolean

      Whether the listener is capturing. If null, removes capturing and non-capturing listeners.

    Returns number

    The number of listeners removed.

toLocaleString

  • toLocaleString(): string
  • Returns a date converted to a string using the current locale.

    Returns string

toString

  • toString(): string
  • Returns a string representation of an object.

    Returns string

valueOf

  • valueOf(): Object
  • Returns the primitive value of the specified object.

    Returns Object

Static disposeAll

  • disposeAll(e?: HTMLElement): void
  • Disposes of all Wijmo controls contained in an HTML element.

    Parameters

    • Optional e: HTMLElement

      Container element.

    Returns void

Static getControl

  • getControl(element: any): Control
  • Gets the control that is hosted in a given DOM element.

    Parameters

    • element: any

      The DOM element that hosts the control, or a CSS selector for the host element (e.g. '#theCtrl').

    Returns Control

Static invalidateAll

  • invalidateAll(e?: HTMLElement): void
  • Invalidates all Wijmo controls contained in an HTML element.

    Use this method when your application has dynamic panels that change the control's visibility or dimensions. For example, splitters, accordions, and tab controls usually change the visibility of its content elements. In this case, failing to notify the controls contained in the element may cause them to stop working properly.

    If this happens, you must handle the appropriate event in the dynamic container and call the Control.invalidateAll method so the contained Wijmo controls will update their layout information properly.

    Parameters

    • Optional e: HTMLElement

      Container element. If set to null, all Wijmo controls on the page will be invalidated.

    Returns void

Static refreshAll

  • refreshAll(e?: HTMLElement): void
  • Refreshes all Wijmo controls contained in an HTML element.

    This method is similar to invalidateAll, except the controls are updated immediately rather than after an interval.

    Parameters

    • Optional e: HTMLElement

      Container element. If set to null, all Wijmo controls on the page will be invalidated.

    Returns void

Events

displayMonthChanged

displayMonthChanged: Event

Occurs after the displayMonth property changes.

formatItem

formatItem: Event

Occurs when an element representing a day in the calendar has been created.

This event can be used to format calendar items for display. It is similar in purpose to the itemFormatter property, but has the advantage of allowing multiple independent handlers.

For example, the code below uses the formatItem event to disable weekends so they appear dimmed in the calendar:

// disable Sundays and Saturdays
calendar.formatItem.addHandler(function (s, e) {
  var day = e.data.getDay();
  if (day == 0 || day == 6) {
    wijmo.addClass(e.item, 'wj-state-disabled');
  }
});

gotFocus

gotFocus: Event

Occurs when the control gets the focus.

lostFocus

lostFocus: Event

Occurs when the control loses the focus.

refreshed

refreshed: Event

Occurs after the control has refreshed its contents.

refreshing

refreshing: Event

Occurs when the control is about to refresh its contents.

valueChanged

valueChanged: Event

Occurs when the value of the value property changes, either as a result of user actions or by assignment in code.
