# Wijmo_Input.Inputdaterange ## Content

InputDateRange Class

The InputDateRange control extends the InputDate control and sets the selectionMode property to DateSelectionMode.Range, the monthCount property to 2, and the showMonthPicker property to ShowMonthPicker.Outside.

Use the value and rangeEnd properties to access the currently selected date range.

Use the predefinedRanges property to add pre-defined ranges that users can select from.

Properties

alwaysShowCalendar

alwaysShowCalendar: boolean

Gets or sets a value that determines whether the calendar should remain visible in the dropdown even when there are selected predefined ranges.

The default value for this property is false, which causes the control to hide the calendar if one of the predefined ranges is selected.

ariaLabelledBy

ariaLabelledBy: string

Gets or sets the aria-labelledby attribute of input element.

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.

clickAction

clickAction: ClickAction

Gets or sets a value that specifies the action to perform when the user clicks the input element in the control.

For most drop-down controls, this property is set to ClickAction.Select by default. This setting allows users to select portions of the text with the mouse.

For drop-down controls that display non-editable text (such as the MultiSelect), this property is set to ClickAction.Toggle by default.

closeOnSelection

closeOnSelection: boolean

Gets or sets a value that determines whether the control should automatically close the drop-down when the user makes a selection.

The default value for this property is true.

dropDown

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).

handleWheel

handleWheel: boolean

Gets or sets a value that determines whether the user can edit the current value using the mouse wheel.

The default value for this property is true.

Setting this property to false also disables the custom wheel handling for the control's drop-down calendar.

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.

For example, the code below uses the inputElement property to improve accessibility by adding an aria-label attribute to the control's input element:

// create an InputDate control and add an aria-label for improved accessibility
let inputDate = new InputDate('#theInputDate');
inputDate.inputElement.setAttribute('aria-label', 'enter trip start date in the format month/day/year')

inputType

inputType: string

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

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 "tel" or "text"

isAnimated

isAnimated: boolean

Gets or sets a value that indicates whether the control should use a fade-in animation when displaying the drop-down.

The default value for this property is false.

isDisabled

isDisabled: boolean

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

Disabled controls cannot get mouse or keyboard events.

isDroppedDown

isDroppedDown: boolean

Gets or sets a value that indicates whether the drop down is currently visible.

The default value for this property is false.

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 that determines whether the control value must be set to a non-null value or whether it can be set to null (by deleting the content of the control).

This property defaults to true for most controls, including ComboBox, InputDate, InputTime, InputDateTime, and InputColor. It defaults to false for the AutoComplete control.

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.

itemFormatter

itemFormatter: IDateFormatter

Gets or sets a formatter function to customize dates in the drop-down 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:

inputDate.itemFormatter = (date, element) => {
    const day = date.getDay();
    element.style.backgroundColor = day == 0 || day == 6 ? 'yellow' : '';
}

itemValidator

itemValidator: IDateValidator

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 prevents users from selecting dates that fall on weekends:

inputDate.itemValidator = date => {
    const weekday = date.getDay();
    return weekday != 0 && weekday != 6;
}

keepInvalidText

keepInvalidText: boolean

Gets or sets whether to allow invalid text

This property is used only when invalid text is set through text property in code and does not affect the behavior when invalid value is set by the end user

The default value for this property is false.

keyActionDownArrow

keyActionDownArrow: KeyAction

Gets or sets the action to perform when the DOWN ARROW key is pressed.

The default setting for this property is KeyAction.ChangeSelectionOnly, which causes the control to change the selection item while keeping the listbox closed.

Alternatively, you can set this to KeyAction.OpenDropdown to open the listbox without changing the current selection.

keyActionTab

keyActionTab: TabKeyAction

Gets or sets the action to perform when the TAB key is pressed.

The default setting for this property is TabKeyAction.CloseAndMoveFocus, which provides standard form navigation behavior by:

  • Closing the dropdown (if open)
  • Moving focus to the next focusable element

For specialized cases, you can set this to TabKeyAction.CloseAndKeepFocus to maintain focus on the control after closing the dropdown.

This setting is particularly useful for controlling accessibility behavior and keyboard navigation flow in form controls.

Example:

// Change TAB key behavior
dropDown.keyActionTab = TabKeyAction.CloseAndMoveFocus;

keyActionUpArrow

keyActionUpArrow: KeyAction

Gets or sets the action to perform when the UP ARROW key is pressed.

The default setting for this property is KeyAction.ChangeSelectionOnly, which causes the control to change the selection item while keeping the listbox closed.

Alternatively, you can set this to KeyAction.OpenDropdown to open the listbox without changing the current selection.

mask

mask: string

Gets or sets a mask to use while editing.

The mask format is the same one that the wijmo.input.InputMask control uses.

If specified, the mask must be compatible with the value of the format and separator properties.

For example, the mask '99/99/9999 - 99/99/9999' can be used for entering date ranges formatted as 'MM/dd/yyyy' with a ' - ' separator.

max

max: Date | null

Gets or sets the latest date that the user can enter.

The default value for this property is null, which means no latest date is defined.

For details about using the min and max properties, please see the Using the min and max properties topic.

min

min: Date | null

Gets or sets the earliest date that the user can enter.

The default value for this property is null, which means no earliest date is defined.

For details about using the min and max properties, please see the Using the min and max properties topic.

monthCount

monthCount: number

Gets or sets the number of months to display in the drop-down calendar.

The default value for this property is 1.

For more details on this property, please see the Calendar.monthCount property.

When showing multiple months in the same calendar, months will be shown using a wrapping flex-box container. You may use CSS to limit the number of months shown per row in the drop-down.

For example this code creates an InputDate control with a drop-down that shows three months per row:

import { InputDate } from '@mescius/wijmo.input';
let idt = new InputDate(document.createElement('#theInputDate'), {
    monthCount: 6,
    dropDownCssClass: 'three-months-per-row'
});
.three-months-per-row .wj-calendar-multimonth {
    width: calc(3 * 21em);
}

placeholder

placeholder: string

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

predefinedRanges

predefinedRanges: any

Gets or sets an object that defines predefined ranges.

This property is useful only when the selectionMode property is set to DateSelectionMode.Range.

Each property in the object represents a predefined range, identified by the property name and defined by an array with two dates (range start and end).

Properties with null values represent custom ranges to be defined by users by clicking on the calendar.

For example:

import { DateTime } from '@mescius/wijmo';
import { InputDate } from '@mescius/wijmo.input';

new InputDate(host, {
    selectionMode: 'Range',
    predefinedRanges: getRanges()
});

function getRanges() {
    let dt = DateTime,
        now = new Date();
    return {
        'This Week': [dt.weekFirst(now), dt.weekLast(now)],
        'Last Week': [dt.weekFirst(dt.addDays(now, -7)), dt.weekLast(dt.addDays(now, -7))],
        'Next Week': [dt.weekFirst(dt.addDays(now, +7)), dt.weekLast(dt.addDays(now, +7))],

        'This Month': [dt.monthFirst(now), dt.monthLast(now)],
        'Last Month': [dt.monthFirst(dt.addMonths(now, -1)), dt.monthLast(dt.addMonths(now, -1))],
        'Next Month': [dt.monthFirst(dt.addMonths(now, +1)), dt.monthLast(dt.addMonths(now, +1))],
        'Custom Range': null
    };
}

preserveCalendarNavigation

preserveCalendarNavigation: boolean

Gets or sets a value that determines whether to preserve the month when user navigates to a different month than the selected date.

The default value for this property is true.

rangeEnd

rangeEnd: Date

To enable date range selection, set the selectionMode property to DateSelectionMode.Range.

Once you do that, the selection range will be defined by the value and rangeEnd properties.

rangeMax

rangeMax: number

Gets or sets the maximum length allowed when editing date ranges.

This property is used only when the selectionMode property is set to DateSelectionMode.Range.

The default value for this property is 0, which means there is no maximum value for range lengths.

rangeMin

rangeMin: number

Gets or sets the minimum number of days allowed when editing date ranges.

This property is used only when the selectionMode property is set to DateSelectionMode.Range.

The default value for this property is 0, which means there is no minimum value for range lengths.

repeatButtons

Gets or sets a value that determines whether the calendar buttons should act as repeat buttons, firing repeatedly as the button remains pressed.

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.

separator

separator: string

Gets or sets a string used as a separator between the value and rangeEnd values shown by the control.

This property is used only when the selectionMode property is set to DateSelectionMode.Range.

The default value for this property is a ' - '.

showConfirmationButtons

showConfirmationButtons: boolean

Gets or sets whether to display the confirmation buttons in Calendar. When this property is set to true, using the arrow keys will only change the focus. And "OK" and "Cancel" buttons will be displayed below the dropdown.

showDropDownButton

showDropDownButton: boolean

Gets or sets a value that indicates whether the control should display a drop-down button.

The default value for this property is true.

showHeader

showHeader: boolean

Gets or sets a value that determines whether the calendar should display an area with the current month and navigation buttons.

The default value for this property is true.

showMonthPicker

showMonthPicker: boolean | ShowMonthPicker

Gets or sets a value that determines whether the calendar should display a list of months when the user clicks the header element on the month calendar.

The default value for this property is ShowMonthPicker.First.

showYearPicker

showYearPicker: boolean

Gets or sets a value that determines whether the drop-down calendar should display a list of years when the user clicks the header element on the year calendar.

The default value for this property is true.

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.

text

text: string

Gets or sets the text shown on the control.

value

value: Date | null

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. 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

  • 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(shouldInvalidate?: boolean): void

  • Resumes notifications suspended by calls to beginUpdate.

    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

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 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 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<Control, EventArgs>

Occurs when the control gets the focus.

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.

isDroppedDownChanged

isDroppedDownChanged: Event<DropDown, EventArgs>

Occurs after the drop down is shown or hidden.

isDroppedDownChanging

isDroppedDownChanging: Event<DropDown, CancelEventArgs>

Occurs before the drop down is shown or hidden.

lostFocus

lostFocus: Event<Control, EventArgs>

Occurs when the control loses the focus.

rangeChanged

rangeChanged: Event<InputDate, EventArgs>

Occurs when the value of the rangeEnd property changes into a non-null value, indicating a data range has been selected.

rangeEndChanged

rangeEndChanged: Event<InputDate, EventArgs>

Occurs when the value of the rangeEnd property changes.

refreshed

refreshed: Event<Control, EventArgs>

Occurs after the control has refreshed its contents.

refreshing

refreshing: Event<Control, EventArgs>

Occurs when the control is about to refresh its contents.

textChanged

textChanged: Event<DropDown, EventArgs>

Occurs when the value of the text property changes.
