Using Range Slider Control In Onsen UI Using Visual Studio 2015

Before reading this article, please go through the article links, mentioned below.

Apache Cordova

Apache Cordova is an open-source project that aims at allowing mobile developers to build applications for all the major mobile platforms, using HTML, CSS, and JavaScript technologies.

Monaca

Monaca is a software tool and service solution for building and deploying HTML5 mobile hybrid apps. It is built on top of an open-source Apache Cordova. Monaca provides a full suite of resources including Cloud IDE, local development tools, debugger, and back-end support.

Monaca's cloud-based IDE builds HTML5 hybrid mobile apps for iOS, Android, Windows, and Chrome apps, using HTML, CSS, and JavaScript.

Monaca CLI provides Onsen UI templates, device debugger, remote building, and any service that you might need directly from your terminal.

Onsen UI Framework

Onsen UI is a front-end UI framework to develop cross-platform mobile apps, using Apache Cordova and PhoneGap. It’s fully independent of frameworks and you can easily plug these components into any project, regardless of JavaScript framework.

Onsen UI templates can be used with Visual Studio 2015. All the templates are compatible with Visual Studio Tools for Apache Cordova. It works pretty well with UWP, iOS, and Android apps.

Building Range Slider with Onsen UI Framework

The <ons-range> element is used to display a Range Slider. For setting the maximum and minimum value, we use "min" and "max" attributes. The "step" attribute is used to change the value in every step.

It can be disabled using the "disabled" attribute.

Let’s see how to start building the app using Range Slider in Onsen UI Framework and Visual Studio 2015.
