WjPopup Class

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.

Properties

Methods

Events

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.

The default value for this property is null.

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.

dialogResultSubmit

dialogResultSubmit: string

Gets or sets a string to be used as a dialogResult when the dialog is hosted by a form element and the user submits the form.

The default value for this property is null.

If you set this property to a non-empty string, the control will handle the form's submit event, validating the fields and closing the form with a dialogResult set to the specified value. For example:

let dlg = new Popup('#theForm', {
    dialogResultSubmit: 'ok'
});
dlg.show(true, () => {
    if (dlg.dialogResult == dlg.dialogResultSubmit) {
        // form is valid, handle results here
    }
});

See also the dialogResultEnter property, which can be used when the Popup is hosted in elements that are not forms.

draggedNg

draggedNg: EventEmitter<any>

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

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.

The default value for this property is PopupTrigger.Blur, which causes the popup to hide when it loses focus.

If you set the hideTrigger property to PopupTrigger.Click, the popup will be hidden when the user clicks the popup or its owner element.

If you set the hideTrigger property to PopupTrigger.Leave, the popup will be hidden a short interval after the mouse leaves the popup or its owner element, unless the user moves the mouse back into the popup before the interval elapses.

If you set the hideTrigger property to PopupTrigger.None, the popup will be hidden only when the hide method is called (or when the user presses the Escape key).

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.

invalidInputNg

invalidInputNg: EventEmitter<any>

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

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' or '.modal-header' CSS selectors. If the dialog does not contain any elements with the 'wj-dialog-header' or 'modal-header' classes, 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.

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 when the hide method is called (or when the user presses the Escape key).

The default value for this property is false.

owner

owner: HTMLElement | null

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.

position

position: PopupPosition

Gets or sets the PopupPosition where the popup should be displayed with respect to the owner element.

The default value for this property is PopupPosition.BelowLeft.

positionChangedNg

positionChangedNg: EventEmitter<any>

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

positionChangingNg

positionChangingNg: EventEmitter<any>

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

removeOnHide

removeOnHide: boolean

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

The default value for this property is true.

Note that removeOnHide removes the Popup element from the DOM when the Popup is hidden, but not when it is created.

If the Popup contains elements with access keys (accesskey attributes) that should not be activated when the Popup is not visible, you should remove the Popup from the DOM after it is created. For example:

import { Popup} from '@mescius/wijmo.input';
import { removeChild } from '@mescius/wijmo';
// create the Popup
let popup = new Popup('#popup', {
    owner: '#show'
});

// add event listeners to accesskey elements (accesskey element is in the DOM)
document.getElementById('alert').addEventListener('click', e => alert('hi'));

// remove Popup (and accesskey element) from DOM
// so accesskey will not work until the Popup is visible
removeChild(popup.hostElement);

resizedNg

resizedNg: EventEmitter<any>

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

resizingNg

resizingNg: EventEmitter<any>

showTrigger

showTrigger: PopupTrigger

Gets or sets the actions that show the Popup.

The default value for this property is PopupTrigger.ClickOwner, which causes the popup to appear when the user clicks the owner element.

If you set the showTrigger property to PopupTrigger.None, the popup will be shown only when the show method is called.

showingNg

showingNg: EventEmitter<any>

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

shownNg

shownNg: EventEmitter<any>

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

sizeChangedNg

sizeChangedNg: EventEmitter<any>

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

sizeChangingNg

sizeChangingNg: EventEmitter<any>

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

tabOrder

tabOrder: number

Gets or sets a value of the tabindex attribute associated with the control.

tabindex attribute value can be defined statically for a Wijmo control by specifying it on the control's host HTML element. But this value can't be changed later during application lifecycle, because Wijmo controls have complex structure, and the control may need to propagate this attribute value to its internal element to work properly.

Because of this, to read or change control's tabindex dynamically, you should do it using this property.

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. Therefore, this method is not available. 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', templateString, {
  _tbx: 'input',
  _btnUp: 'btn-inc',
  _btnDn: 'btn-dec'
}, 'input');

    @param classNames Names of classes to add to the control's host element. @param template An HTML string that defines the control template. @param parts A dictionary of part variables and their names. @param namePart Name of the part to be named after the host element. This determines how the control submits data when used in forms.

    Parameters

    • classNames: string
    • template: string
    • parts: Object
    • Optional namePart: string

    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(shouldInvalidate?: boolean): void

  • Resumes notifications suspended by calls to beginUpdate.

    Parameters

    • Optional shouldInvalidate: boolean

      should invalidate the control. Default value for this parameter is true.

    Returns 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

onDragged

onDragging

onGotFocus

onHidden

onRefreshed

onRefreshing

onResized

onResizing

onShowing

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:

      function editCurrentItem(popupEditor: Popup, view: CollectionView) {
    view.editItem(view.currentItem);
    popupEditor.show(true, (e: Popup) => {
        if (e.dialogResult == 'wj-hide-ok') {
            view.commitEdit();
        } else {
            view.cancelEdit();
        }
    });
}

    Returns void

toLocaleString

  • 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

  • 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

dragged

dragged: Event<Popup, EventArgs>

Occurs after the Popup has been dragged.

See also the isDraggable property.

dragging

dragging: Event<Popup, CancelEventArgs>

Occurs when the Popup is about to be dragged.

See also the isDraggable property.

Occurs after the Popup has been hidden.

hiding

hiding: Event<Popup, CancelEventArgs>

Occurs before the Popup is hidden.

invalidInput

invalidInput: Event<Control, CancelEventArgs>

Occurs when invalid input is detected.

Invalid input may occur when the user types or pastes a value that cannot be converted to the proper type, or a value that is outside the valid range.

If the event handler cancels the event, the control will retain the invalid content and the focus, so users can correct the error.

If the event is not canceled, the control will ignore the invalid input and will retain the original content.

lostFocus

lostFocus: Event<Control, EventArgs>

Occurs when the control loses the focus.

positionChanged

positionChanged: Event<Popup, EventArgs>

Occurs while the user moves the Popup, between the dragging and dragged events.

When the user drags the Popup, it raises the following events:

See also the isDraggable property.

positionChanging

positionChanging: Event<Popup, PopupBoundsChangingEventArgs>

Occurs while the user moves the Popup, between the dragging and dragged events.

When the user drags the Popup, it raises the following events:

See also the isDraggable property.

You can use the positionChanging event to cancel or to modify the Popup bounds as the user drags the control.

For example, the code keeps the popup in full view, preventing users from dragging parts of the Popup off the screen:

new Popup('#thePopup', {
    isDraggable: true,
    isResizable: true,
    hideTrigger: 'None',

    // keep popup fully within the browser window
    positionChanging: (s: Popup, e: PopupBoundsChangingEventArgs) => {
        let bnd = e.bounds;
        bnd.left = Math.max(Math.min(bnd.left, innerWidth + scrollX - bnd.width), scrollX);
        bnd.top = Math.max(Math.min(bnd.top, innerHeight + scrollY - bnd.height), scrollY);
    }
});
