InputMask Class

The InputMask control provides a way to govern what a user is allowed to enter.

The control prevents users from accidentally entering invalid data and saves time by skipping over literals (such as slashes in dates) as the user types.

The mask used to validate the input is defined by the InputMask.mask property, which may contain one or more of the following special characters:

0
Digit.
9
Digit or space.
#
Digit, sign, or space.
L
Letter.
l
Letter or space.
A
Alphanumeric.
a
Alphanumeric or space.
.
Localized decimal point.
,
Localized thousand separator.
:
Localized time separator.
/
Localized date separator.
$
Localized currency symbol.
<
Converts characters that follow to lowercase.
>
Converts characters that follow to uppercase.
|
Disables case conversion.
\
Escapes any character, turning it into a literal.
DBCS Digit.
DBCS Hiragana.
DBCS big Hiragana.
DBCS Katakana.
DBCS big Katakana.
K
SBCS Katakana.
N
SBCS big Katakana.
Any DBCS character.
H
Any SBCS character.
All others
Literals.

The example below shows how you can use the InputMask control to edit strings with custom formats:

Example

Hierarchy

Constructors

constructor

  • new InputMask(element: any, options?: any): InputMask
  • Initializes a new instance of the InputMask class.

    Parameters

    • element: any

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

    • Optional options: any

      The JavaScript object containing initialization data for the control.

    Returns InputMask

Properties

hostElement

hostElement: HTMLElement

Gets the DOM element that is hosting the control.

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.

inputType

inputType: string

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

The default value for this property is text.

isDisabled

isDisabled: boolean

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

Disabled controls cannot get mouse or keyboard events.

isReadOnly

isReadOnly: boolean

Gets or sets a value that indicates whether the user can modify the control value using the mouse and keyboard.

The default value for this property is false.

isRequired

isRequired: boolean

Gets or sets a value indicating whether the control value must be a non-empty string.

The default value for this property is true.

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.

mask

mask: string

Gets or sets the mask used to validate the input as the user types.

The mask is defined as a string with one or more of the masking characters listed in the InputMask topic.

maskFull

maskFull: boolean

Gets a value that indicates whether the mask has been completely filled.

placeholder

placeholder: string

Gets or sets the string shown as a hint when the control is empty.

promptChar

promptChar: string

Gets or sets the symbol used to show input positions in the control.

rawValue

rawValue: string

Gets or sets the raw value of the control (excluding mask literals).

The raw value of the control excludes prompt and literal characters. For example, if the mask property is set to "AA-9999" and the user enters the value "AB-1234", the rawValue property will return "AB1234", excluding the hyphen that is part of the mask.

rightToLeft

rightToLeft: boolean

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

value

value: string

Gets or sets the text currently shown in the control.

Static controlTemplate

controlTemplate: string

Gets or sets the template used to instantiate InputMask controls.

Methods

addEventListener

  • addEventListener(target: EventTarget, type: string, fn: any, capture?: boolean, passive?: boolean): void
  • Adds an event listener to an element owned by this Control.

    The control keeps a list of attached listeners and their handlers, making it easier to remove them when the control is disposed (see the dispose and removeEventListener methods).

    Failing to remove event listeners may cause memory leaks.

    The passive parameter is set to false by default, which means the event handler may call event.preventDefault(). If you are adding passive handlers to touch or wheel events, setting this parameter to true will improve application performance.

    For details on passive event listeners, please see Improving scrolling performance with passive listeners.

    Parameters

    • target: EventTarget

      Target element for the event.

    • type: string

      String that specifies the event.

    • fn: any

      Function to execute when the event occurs.

    • Optional capture: boolean

      Whether the listener should be handled by the control before it is handled by the target element.

    • Optional passive: boolean

      Indicates that the handler will never call preventDefault().

    Returns void

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

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

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.

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

Events

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
