The WjInputDateTime component is derived from the InputDateTime 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.

autoExpandSelection

autoExpandSelection: boolean

Gets or sets a value that indicates whether the control should automatically expand the selection to whole words/numbers when the control is clicked.

The default value for this property is true.

calendar

calendar: Calendar

Gets a reference to the Calendar control shown in the drop-down box.

dropDown: HTMLElement

Gets the drop down element shown when the isDroppedDown property is set to true.

dropDownCssClass

dropDownCssClass: string

Gets or sets a CSS class name to add to the control's drop-down element.

This property is useful when styling the drop-down element, because it is shown as a child of the document body rather than as a child of the control itself, which prevents using CSS selectors based on the parent control.

format

format: string

Gets or sets the format used to display the selected date.

The format string is expressed as a .NET-style Date format string.

The default value for this property is d, the culture-dependent short date pattern (e.g. 6/15/2020 in the US, 15/6/2020 in France, or 2020/6/15 in Japan).

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.

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.

inputElement

inputElement: HTMLInputElement

Gets the HTML input element hosted by the control.

Use this property in situations where you want to customize the attributes of the input element.

inputTime

inputTime: InputTime

Gets a reference to the inner InputTime control so you can access its full object model.

inputType

inputType: string

Gets or sets the "type" attribute of the HTML input element hosted by the control.

By default, this property is set to "tel", a value that causes mobile devices to show a numeric keypad that includes a negative sign and a decimal separator.

Use this property to change the default setting if the default does not work well for the current culture, device, or application. In those cases, try changing the value to "number" or "text."

Note that input elements with type "number" prevent selection in Chrome and therefore is not recommended. For more details, see this link: http://stackoverflow.com/questions/21177489/selectionstart-selectionend-on-input-type-number-no-longer-allowed-in-chrome

Static controlTemplate

controlTemplate: string

Gets or sets the template used to instantiate InputDateTime 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

onIsDroppedDownChanging

onRefreshed

onRefreshing

onTextChanged

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.

selectAll

  • selectAll(): void
  • Sets the focus to the control and selects all its content.

    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
