Typescript Types
When using with typescript, the following types are available for the Numpad:
Type | Description |
---|---|
Numpad | Type of the Numpad instance |
MbscNumpadOptions | Type of the settings object that is used to initialize the component |
Options
Name | Type | Default value | Description |
---|---|---|---|
allowLeadingZero | Boolean | false |
If true, allows value to start with zero. |
anchor | String, HTMLElement | undefined |
Specifies the anchor element for positioning, if display is set to
'bubble'
.
If undefined, it defaults to the element on which the component was initialized.
|
animate | String or Boolean | undefined |
Animation to use for show/hide (if display is not inline). Possible values:
false , turns the animation off.
|
buttons | Array |
['set', 'cancel']
|
Buttons to display. Each item in the array will be a button. A button can be specified as a string, or as a button object.
When the passed array does not contain the predefined 'set' button, the auto-selection will be turned on.
Selecting a value on the UI this way, will be set to the input immediately.
If there are more than one wheels shown, the control will close on overlay tap. Otherwise tapping a value on the wheel will also close the control.
If a string, it must be one of the predefined buttons:
If an object, it may have the following properties:
Predefined and custom buttons example

If false , no focusing will occur.
|
focusTrap | Boolean | true |
If not in inline mode, focus won't be allowed to leave the popup. |
headerText | Boolean, String, Function | false |
Specifies a custom string which appears in the popup header. If the string contains the '{value}' substring, it is replaced with the formatted value of the numpad.If it's set to false , the header is hidden.If a function is passed, it receives the formatted value as parameter and the returned value appears in the header. |
layout | String | undefined |
Sets the layout of the component. Possible values:
|
leftKey | Object | undefined |
Defines a custom key on the left side of the 0.
The object has the following properties:

If it is If the theme for the specific platform is not present, it will default to the Mobiscroll theme. Supplied themes:
Starting from v4.9.0 setting directly the dark version of the theme is deprecated.
Use the themeVariant option instead to control the light / dark appearance of the theme.
Make sure that the theme you set is included in the downloaded package.
|
themeVariant | String | undefined |
Controls which variant of the theme will be used (light or dark). Possible values:
If not set, only the theme setting will determine which theme to use.
To use the option with custom themes, make sure to create two custom themes,
where the dark version has the same name as the light one, suffixed with

sets the dark version of a theme, e.g.
theme: 'ios-dark' .
|
touchUi | Boolean | true |
Use Can be used with the responsive option to change the user interface based on viewport width. |
Setting options dynamically
There are two ways to modify options after initalization
-
Using the option method.
The option method always triggers reinitialization. Most of the settings can be updated only this way, updating without initialization has no effect, because the markup is already generated. If the scroller was visible, the reinitialization hides it and it's not shown again automatically (except in inline display mode).
Javascript// Modify options $('#mobiscroll').mobiscroll('option', { theme: 'ios', lang: 'de' });
HTML<input id="mobiscroll"/>
-
Modify directly the
settings
object.
Useful when changing dynamic settings, which do not need redraw (e.g. readonly, calendar marked days).
// Get instance and modify a setting var inst = $('#mobiscroll').mobiscroll('getInst'); inst.settings.readonly = true; // Modify settings in an event $('#mobiscroll').mobiscroll({ onBeforeShow: function (event, inst) { inst.settings.readonly = true; } });
Events
Name | Description | |
---|---|---|
onBeforeClose(event, inst) |
Triggered before the component closes. Close can be prevented by returning false from the handler function.
Parameters
Example
|
|
onBeforeShow(event, inst) |
Triggered before the component is shown.
It is useful if you want to modify the settings object before generating the markup.
It can be used also to prevent the showing the control by returning false.
Parameters
Example
|
|
onCancel(event, inst) |
Allows you to define your own event when cancel is pressed.
Parameters
Example
|
|
onClear(event, inst) |
Triggered when the value is cleared.
Parameters
Example
|
|
onClose(event, inst) |
Triggered when the component is closed.
Parameters
Example
|
|
onDestroy(event, inst) |
Triggered when the component is destroyed.
Parameters
Example
|
|
onInit(event, inst) |

onInput(event, inst) |
Triggered when a value is entered or deleted.
Parameters
Example
|
|
onMarkupReady(event, inst) |
Triggered when the html markup of the component is generated, but it is not yet shown.
It is useful, if you want to make modifications to the markup (e.g. add custom elements), before the positioning runs.
Parameters
Example
|
|
onPosition(event, inst) |
Triggered when the component is positioned (on initial show and resize / orientation change).
Useful if dimensions needs to be modified before the positioning happens, e.g. set a custom width or height. Custom positioning can also be implemented here, in this case, returning false from the handler
function will prevent the built in positioning.
Parameters
Example
|
|
onSet(event, inst) |
Triggered when a value is set.
Parameters
Example
|
|
onShow(event, inst) |
Triggered when the component is shown.

Customizing the appearance
While the provided pre-built themes are enough in many use cases, most of the times on top of adapting to a specific platform, you'd also like to match a brand or color scheme. Mobiscroll provides various ways to achieve this:
- Create custom themes using the theme builder - the custom themes can be also built using out theme builder, on a graphical user interface, without any coding, or the need for Sass support in your project.
- Create custom themes using Sass - use this, if you need multiple themes with different color variatons, in case you have pages with different colors, or you'd like to users to customize the colors of your app.
- Override the Sass color variables - the straightforward way to change the colors in one place throughout the application.
Override the Sass Color Variables
A convenient way to customize the colors of the Mobiscroll components is to override the Sass color variables.
Let's say your branding uses a nice red accent color, and you'd like that color to appear on the Mobiscroll components as well,
while still using platform specific themes (e.g. ios
on iOS devices, material
on Android devices, and mobiscroll
on desktop).
You can override the accent color for every theme:
$mbsc-ios-accent: #e61d2a;
$mbsc-material-accent: #e61d2a;
$mbsc-mobiscroll-accent: #e61d2a;
@import "~@mobiscroll/JQuery/dist/css/mobiscroll.jquery.scss"
You can also customize the colors on many levels:
- Theme specific variables (ex.
$mbsc-material-background
,$mbsc-ios-dark-text
) are applied to all components in a theme. Complete list of variables here. - Component specific global variables (ex.
$mbsc-card-background-light
,$mbsc-listview-text-dark
) are applied to all themes for a specific component. - Component and theme specific variables (ex.
$mbsc-ios-dark-form-background
,$mbsc-material-input-text
) are applied to a specific theme and a specific component.
Global variables
These variables are applied to all base themes: iOS, material, windows and mobiscroll.
They all come in pairs. One for the light and one for the dark variant in each theme.
Variable name | Description |
---|---|
$mbsc-frame-background-light | Sets the background color of the Numpad |
$mbsc-frame-background-dark | |
$mbsc-frame-text-light | Sets the text color of the Numpad |
$mbsc-frame-text-dark | |
$mbsc-frame-accent-light | Sets the accent color of the Numpad |
$mbsc-frame-accent-dark | |
$mbsc-frame-overlay-light | Sets the color of the overlay, when the Numpad is shown as a modal |
$mbsc-frame-overlay-dark |
If you really want to get sophisticated or if a color doesn't look good on a specific theme and you want to overwrite it, you can fine tune all of the above variables individually for each theme. Below are the complete list of variables broken down to themes:
