WjPopup Class

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

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

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

Hierarchy

Properties

content

content: HTMLElement

Gets or sets the HTML element contained in this Popup.

dialogResult

dialogResult: any

Gets or sets a value used as a return value for the Popup after it is hidden.

This property is set to null when the Popup is displayed. It can be set in response to button click events or in the call to the hide method to provide a result value to callers.

dialogResultEnter

dialogResultEnter: any

Gets or sets a value to be used as a dialogResult when the user presses the Enter key while the Popup is visible.

If the user presses Enter and the dialogResultEnter property is not null, the popup checks whether all its child elements are in a valid state. If so, the popup is closed and the dialogResult property is set to the value of the dialogResultEnter property.

fadeIn

fadeIn: boolean

Gets or sets a value that determines whether the Popup should use a fade-in animation when it is shown.

The default value for this property is true.

fadeOut

fadeOut: boolean

Gets or sets a value that determines whether the Popup should use a fade-out animation when it is hidden.

The default value for this property is true.

gotFocusNg

gotFocusNg: EventEmitter<any>

Angular (EventEmitter) version of the Wijmo gotFocus 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 gotFocus Wijmo event name.

hiddenNg

hiddenNg: EventEmitter<any>

Angular (EventEmitter) version of the Wijmo hidden 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 hidden Wijmo event name.

hideTrigger

hideTrigger: PopupTrigger

Gets or sets the actions that hide the Popup.

By default, the hideTrigger property is set to PopupTrigger.Blur, which hides the popup when it loses focus.

If you set the hideTrigger property to PopupTrigger.Click, the popup will be hidden only when the owner element is clicked.

If you set the hideTrigger property to PopupTrigger.None, the popup will be hidden only when the hide method is called.

hidingNg

hidingNg: EventEmitter<any>

Angular (EventEmitter) version of the Wijmo hiding 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 hiding 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.

isDraggable

isDraggable: boolean

Gets or sets a value that determines whether the popup can be dragged with the mouse by its header.

The header is identified by the '.wj-dialog-header' CSS selector. If the dialog does not contain any elements with the 'wj-dialog-header' class, users will not be able to drag the popup.

The default value for this property is false.

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.

isResizable

isResizable: boolean

Gets or sets a value that determines whether the popup can be resized by dragging its edges with the mouse.

You can limit the size of the popup by setting the host element's max-width, min-width, max-height, and min-height CSS properties.

The default value for this property is false.

isTouching

isTouching: boolean

Gets a value that indicates whether the control is currently handling a touch event.

isUpdating

isUpdating: boolean

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

isVisible

isVisible: boolean

Gets a value that determines whether the Popup is currently visible.

lostFocusNg

lostFocusNg: EventEmitter<any>

Angular (EventEmitter) version of the Wijmo lostFocus 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 lostFocus Wijmo event name.

modal

modal: boolean

Gets or sets a value that determines whether the Popup should be displayed as a modal dialog.

Modal dialogs show a dark backdrop that makes the Popup stand out from other content on the page.

If you want to make a dialog truly modal, also set the Popup.hideTrigger property to PopupTrigger.None, so users won't be able to click the backdrop to dismiss the dialog. In this case, the dialog will close only if the Popup.hide method is called or if the user presses the Escape key.

The default value for this property is false.

owner

owner: HTMLElement

Gets or sets the element that owns this Popup.

If the owner is null, the Popup behaves like a dialog. It is centered on the screen and must be shown using the show method.

refreshedNg

refreshedNg: EventEmitter<any>

Angular (EventEmitter) version of the Wijmo refreshed 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 refreshed Wijmo event name.

refreshingNg

refreshingNg: EventEmitter<any>

Angular (EventEmitter) version of the Wijmo refreshing 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 refreshing Wijmo event name.

removeOnHide

removeOnHide: boolean

Gets or sets a value that determines whether the Popup element should be removed from the DOM when the Popup is hidden, as opposed to being hidden.

The default value for this property is true.

rightToLeft

rightToLeft: boolean

Gets a value indicating whether the control is hosted in an element with right-to-left layout.

showTrigger

showTrigger: PopupTrigger

Gets or sets the actions that show the Popup.

wjModelProperty

wjModelProperty: string

Defines a name of a property represented by [(ngModel)] directive (if specified). Default value is ''.

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

containsFocus

  • containsFocus(): boolean
  • Checks whether this control contains the focused element.

    Returns boolean

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

hide

  • hide(dialogResult?: any): void
  • Hides the Popup.

    Parameters

    • Optional dialogResult: any

      Optional value assigned to the dialogResult property before closing the Popup.

    Returns void

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

onGotFocus

onHidden

onHiding

onRefreshed

onRefreshing

onShowing

onShown

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.

show

  • show(modal?: boolean, handleResult?: Function): void
  • Shows the Popup.

    Parameters

    • Optional modal: boolean

      Whether to show the popup as a modal dialog. If provided, this sets the value of the modal property.

    • Optional handleResult: Function

      Callback invoked when the popup is hidden. If provided, this should be a function that receives the popup as a parameter.

      The handleResult callback allows callers to handle the result of modal dialogs without attaching handlers to the hidden event. For example, the code below shows a dialog used to edit the current item in a CollectionView. The edits are committed or canceled depending on the Popup.dialogResult value. For example:

      $scope.editCurrentItem = function () {
        $scope.data.editItem($scope.data.currentItem);
        $scope.itemEditor.show(true, function (e) {
          if (e.dialogResult == 'wj-hide-ok') {
            $scope.data.commitEdit();
          } else {
            $scope.data.cancelEdit();
          }
        });
      }

    Returns void

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
