UI Widgets NumberBox

A textbox widget that enables a user to enter numeric values.

Included in: dx.phonejs.js, dx.webappjs.js, dx.all.js

The dxNumberBox widget allows a user to enter a number between the specified min and max configuration option values.

This widget, like any other DevExtreme UI widget, can be created using one of three possible approaches: jQuery, Knockout or AngularJS. The following code demonstrates how to create the dxNumberBox widget using the Knockout approach.

HTML
<div data-bind="dxNumberBox:{min:0, max:100, value:number}"></div>

The current widget value is specified by the value option.

Declare an observable variable and pass it to the value option to update the variable each time the widget value changes.

JavaScript
var number = ko.observable(0);
